reginfo and secinfo location in sap

Only clients from domain *.sap.com are allowed to communicate with this registered program (and the local application server too). The RFC Gateway hands over the request from the RFC client to the dispatcher which assigns it to a work process (AS ABAP) or to a server process (AS Java). For a RFC Gateway of AS Java or a stand-alone RFC Gateway this can be determined with the command-line tool gwmon by running the command gwmon nr= pf= then going to the menu by typing m and displaying the client table by typing 3. As separators you can use commas or spaces. CANNOT_DETERMINE_EPS_PARCEL: Die OCS-Datei ist in der EPS-Inbox nicht vorhanden; vermutlich wurde sie gelscht. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. This ACL is applied on the ABAP layer and is maintained in transaction SNC0. Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. Auch hier ist jedoch ein sehr groer Arbeitsaufwand vorhanden. As we learned in part 4 SAP introduced the following internal rule in the in the prxyinfo ACL: Only clients from the local application server are allowed to communicate with this registered program. Please note: The wildcard * is per se supported at the end of a string only. Someone played in between on reginfo file. TP is a mandatory field in the secinfo and reginfo files. The location of this ACL can be defined by parameter gw/acl_info. Its location is defined by parameter gw/sec_info. The PI system has one Central Instance (CI) running at the server sappici, and one application instance (running at the server sappiapp1). Most of the cases this is the troublemaker (!) Thus, part of your reginfo might not be active.The gateway is logging an error while performing name resolution.The operating system / DNS took 5 seconds to reply - 5006ms per the error message you posted; and the response was "host unknown".If the "HOST" argument on the reginfo rule from line 9 has only one host, then the whole rule is ignored as the Gateway could not determine the IP address of the server.Kind regards. This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. (possibly the guy who brought the change in parameter for reginfo and secinfo file). Firstly review what is the security level enabled in the instance as per the configuration of parameter gw/reg_no_conn_info. Part 6: RFC Gateway Logging To permit registered servers to be used by local application servers only, the file must contain the following entry. You can also control access to the registered programs and cancel registered programs. After an attack vector was published in the talk SAP Gateway to Heaven from Mathieu Geli and Dmitry Chastuhin at OPDCA 2019 Dubai (https://github.com/gelim/sap_ms) the RFC Gateway security is even more important than ever. About the second comment and the error messages, those are messages related to DNS lookup.I believe that these are raised as errors because they have occurred during the parsing of the reginfo file. Every attribute should be maintained as specific as possible. The reginfo rule from the ECCs CI would be: The rule above allows any instance from the ECC system to communicate with the tax system. If this addition is missing, any number of servers with the same ID are allowed to log on. The SAP note1689663has the information about this topic. P TP=cpict2 ACCESS=ld8060,localhost CANCEL=ld8060,localhost. Host Name (HOST=, ACCESS= and/or CANCEL=): The wildcard character * stands for any host name, *.sap.com for a domain, sapprod for host sapprod. In summary, if the Simulation Mode is deactivated (parameter gw/sim_mode = 0; default value), the last implicit rule from the RFC Gateway will be Deny all as mentioned above, at the RFC Gateway ACLs (reginfo and secinfo) section. As such, it is an attractive target for hacker attacks and should receive corresponding protections. After an attack vector was published in the talk SAP Gateway to Heaven from Mathieu Geli and Dmitry Chastuhin at OPDCA 2019 Dubai (https://github.com/gelim/sap_ms) the RFC Gateway security is even more important than ever. P USER=* USER-HOST=internal,local HOST=internal,local TP=*. There are other SAP notes that help to understand the syntax (refer to the Related notes section below). Program hugo is allowed to be started on every local host and by every user. No error is returned, but the number of cancelled programs is zero. In other words, the SAP instance would run an operating system level command. Dieses Verfahren ist zwar sehr restriktiv, was fr die Sicherheit spricht, hat jedoch den sehr groen Nachteil, dass in der Erstellungsphase immer Verbindungen blockiert werden, die eigentlich erwnscht sind. P TP=* USER=* USER-HOST=internal HOST=internal. Its location is defined by parameter gw/reg_info. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Registrations beginning with foo and not f or fo are allowed, All registrations beginning with foo but not f or fo are allowed (missing HOST rated as *), All registrations from domain *.sap.com are allowed. All subsequent rules are not even checked. You have already reloaded the reginfo file. In this case, the secinfo from all instances is relevant as the system will use the local RFC Gateway of the instance the user is logged on to start the tax program. After an attack vector was published in the talk SAP Gateway to Heaven from Mathieu Geli and Dmitry Chastuhin at OPDCA 2019 Dubai (https://github.com/gelim/sap_ms) the RFC Gateway security is even more important than ever. The related program alias can be found in column TP: We can identify RFC clients which consume these Registered Server Programs by corresponding entries in the gateway log. This is a list of host names that must comply with the rules above. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. This section contains information about the RFC Gateway ACLs, and examples of landscapes and rules.The reginfo file have ACLs (rules) related to the registration of external programs (systems) to the local SAP instance. (any helpful wiki is very welcome, many thanks toIsaias Freitas). In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_PRXY_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. 2. Part 3: secinfo ACL in detail. You dont need to define a deny all rule at the end, as this is already implicit (if there is no matching Permit rule, and the RFC Gateway already checked all the rules, the result will be Deny except when the Simulation Mode is active, see below). You have a non-SAP tax system that needs to be integrated with SAP. Somit knnen keine externe Programme genutzt werden. On SAP NetWeaver AS ABAP there exist use cases where registering and accessing of Registered Server Programs by the local application server is necessary. Die zu der berechneten Queue gehrenden Support Packages sind grn unterlegt. That part is talking about securing the connection to the Message Server, which will prevent tampering with they keyword "internal", which can be used on the RFC Gateway security ACL files. With secinfo file this corresponds to the name of the program on the operating system level. Giving more details is not possible, unfortunately, due to security reasons. Somit knnen keine externe Programme genutzt werden. We can identify these use cases by going to transaction SMGW -> Goto -> Logged on Clients and looking for programs listed with System Type = Registered Server and Gateway Host set to any IP address or hostname not belonging to any application server of the same system. Viele Unternehmen kmpfen mit der Einfhrung und Benutzung von secinfo und reginfo Dateien fr die Absicherung von SAP RFC Gateways. Ergebnis Sie haben eine Queue definiert. In addition, note that the system checks the case of all keywords and only takes keywords into account if they are written in upper case. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. so for me it should only be a warning/info-message. The Solution Manager (SolMan) system has only one instance, running at the host sapsmci. There are various tools with different functions provided to administrators for working with security files. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo Obviously, if the server is unavailable, an error message appears, which might be better only just a warning, some entries in reginfo and logfile dev_rd shows (if the server is noch reachable), NiHLGetNodeAddr: to get 'NBDxxx' failed in 5006ms (tl=2000ms; MT; UC)*** ERROR => NiHLGetNodeAddr: NiPGetHostByName failed (rc=-1) [nixxhl.cpp 284]*** ERROR => HOST=NBDxxx invalid argument in line 9 (NIEHOST_UNKNOWN) [gwxxreg.c 2897]. The reginfo ACL contains rules related to Registered external RFC Servers. ber das Dropdown-Men regeln Sie, ob und wie weit Benutzer der Gruppe, die Sie aktuell bearbeiten, selbst CMC-Registerkartenkonfigurationen an anderen Gruppen / Benutzern vornehmen knnen! Datenbankschicht: In der Datenbank, welche auf einem Datenbankserver liegt, werden alle Daten eines Unternehmens gesichert. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. We should pretend as if we would maintain the ACLs of a stand-alone RFC Gateway. How can I quickly migrate SAP custom code to S/4HANA? Its functions are then used by the ABAP system on the same host. Default values can be determined from the aggregated Gateway logging and used to assemble control data, and subsequently leverage the control data content for further use. The RFC destination would look like: The secinfo files from the application instances are not relevant. HOST = servername, 10. Help with the understanding of the RFC Gateway ACLs (Access Control Lists) and the Simulation Mode, in order to help prepare production systems to have these security features enabled without disruptions. Another example: you have a non-SAP tax system that will register a program at the CI of an SAP ECC system. If the Gateway protections fall short, hacking it becomes childs play. Examples of valid addresses are: Number (NO=): Number between 0 and 65535. CANCEL is usually a list with all SAP servers from this system (or the keyword "internal"), and also the same servers as in HOSTS (as you must allow the program to de-register itself). D prevents this program from being registered on the gateway. So lets shine a light on security. Part 6: RFC Gateway Logging. Benign programs to be started by the local RFC Gateway of a SAP NetWeaver AS ABAP are typically part of the SAP Kernel and located in the $(DIR_EXE) of the application server. If this client does not match the criteria in the CANCEL list, then it is not able to cancel a registered program. Please pay special attention to this phase! Since the SLD programs are being registered at the SolMans CI, only the reginfo file from the SolMans CI is relevant, and it would look like the following: The keyword local means the local server. What is important here is that the check is made on the basis of hosts and not at user level. In production systems, generic rules should not be permitted. Wir untersttzen Sie gerne bei Ihrer Entscheidungen. Part 5: ACLs and the RFC Gateway security The format of the first line is #VERSION=2, all further lines are structured as follows: Here the line starting with P or D, followed by a space or a TAB, has the following meaning: P means that the program is permitted to be started (the same as a line with the old syntax). Part 8: OS command execution using sapxpg. The name of the registered program will be TAXSYS. At time of writing this can not be influenced by any profile parameter. The network service that, in turn, manages the RFC communication is provided by the RFC Gateway. The wildcard * should be strongly avoided. Common examples are the program tp for transport management via STMS started on the RFC Gateway host of AS ABAP or the program gnetx.exe for the graphical screen painter started on the SAP GUI client host. Trademark. Falls es in der Queue fehlt, kann diese nicht definiert werden. See the examples in the note1592493; 2)It is possible to change the rules in the files and reload its configuration without restart the RFC Gateway: open the transaction SMGW -> Goto -> expert functions -> external security -> reload However, in such situation, it is mandatory to de-register the registered program involved and reregister it again because programs already registered will continue following the old rules; 3)The rules in the secinfo and reginfo file do not always use the same syntax, it depends of the VERSION defined in the file. With this blogpost series i try to give a comprehensive explanation of the RFC Gateway Security: Part 1: General questions about the RFC Gateway and RFC Gateway security. Dieses Verfahren ist zwar sehr restriktiv, was fr die Sicherheit spricht, hat jedoch den sehr groen Nachteil, dass in der Erstellungsphase immer Verbindungen blockiert werden, die eigentlich erwnscht sind. Refer to the SAP Notes 2379350 and2575406 for the details. For example: you have changed to the rule related to the SLD_UC program, allowing a new server to communicate with it (you added the new server to the ACCESS option). When editing these ACLs we always have to think from the perspective of each RFC Gateway to which the ACLs are applied to. Check out our SAST SOLUTIONS website or send us an e-mail us at sast@akquinet.de. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. Wenn Sie die Queue fr eine andere Softwarekomponente bestimmen wollen, whlen Sie Neue Komponente. Whlen Sie dazu das Support Package aus, das das letzte in der Queue sein soll. Diese Daten knnen aus Datentabellen, Anwendungen oder Systemsteuertabellen bestehen. Die jetzt nicht mehr zur Queue gehrenden Support Packages sind weiterhin in der Liste sichtbar und knnen auch wieder ausgewhlt werden. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. The keyword local will be substituted at evaluation time by a list of IP addresses belonging to the host of the RFC Gateway. I think you have a typo. It also enables communication between work or server processes of SAP NetWeaver AS and external programs. If the Simulation Mode is active (parameter gw/sim_mode = 1), the last implicit rule will be changed to Allow all. This parameter will allow you to reproduce the RFC Gateway access and see the TP and HOST that the access is using hence create the rules in the reginfo or secinfo file; 5)The rules defined in the reginfo or secinfo file can be reviewed in colored syntactic correctness. Part 2: reginfo ACL in detail. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. Please assist me how this change fixed it ? Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. For all Gateways, a sec_info-ACL, a prxy_info-ACL and a reg_info-ACL file must be available. You have an RFC destination named TAX_SYSTEM. As we learnt before the reginfo and secinfo are defining rules for very different use-cases, so they are not related. Would you like more information on our SAST SUITE or would you like to find out more about ALL ROUND protection of your SAP systems? Successful and rejected registrations, and calls from registered programs can be ascertained using Gateway Logging with indicator S. Any error lines are put in the trace file dev_rd, and are not read in. They also have a video (the same video on both KBAs) illustrating how the reginfo rules work. Part 2: reginfo ACL in detail. With this blogpost series i try to give a comprehensive explanation of the RFC Gateway Security: Part 1: General questions about the RFC Gateway and RFC Gateway security. Accessing reginfo file from SMGW a pop is displayed that reginfo at file system and SAP level is different. Only the first matching rule is used (similarly to how a network firewall behaves). However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. Here, the Gateway is used for RFC/JCo connections to other systems. Even if the system is installed with an ASCS instance (ABAP Central Services comprising the message server and the standalone enqueue server), a Gateway can still be configured on the ASCS instance. Haben Support Packages in der Queue Verbindungen zu Support Packages einer anderen Komponente (weitere Vorgngerbeziehung, erforderliches CRT) wird die Queue um weitere Support Packages erweitert, bis alle Vorgngerbeziehungen erfllt sind. Again when a remote server of a Registered Server Program is going to be shutdown due to maintenance it may de-register its program from the RFC Gateway to avoid errors. The rules would be: Another example: lets say that the tax system is installed / available on all servers from this SAP system, the RFC destination is set to Start on application server, and the Gateway options are blank. Es gibt folgende Grnde, die zum Abbruch dieses Schrittes fhren knnen: CANNOT_SKIP_ATTRIBUTE_RECORD: Die Attribute knnen in der OCS-Datei nicht gelesen werden. RFCs between two SAP NetWeaver AS ABAP systems are typically controlled on network level only. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. The related program alias can be found in column TP Name: We can verify if the functionality of these Registered RFC Server Programs is accessible from the AS ABAP by looking for a TCP/IP connection in transaction SM59 with Technical Settings Activation Type = Registered Server Program the corresponding Program ID and either no Gateway Options or connection details to any of the RFC Gateways belonging to the same system set: SAP introduced an internal rule in the reginfo ACL to cover these cases: P TP=* HOST=internal,local ACCESS=internal,local CANCEL=internal,local. If the option is missing, this is equivalent to HOST=*. Environment. You can define the file path using profile parameters gw/sec_info and gw/reg_info. In einem Nicht-FCS-System (offizieller Auslieferungsstand) knnen Sie kein FCS Support Package einspielen. RFC had issue in getting registered on DI. Since this keyword is relaying on a kernel feature as well as an ABAP report it is not available in the internal RFC Gateway of SAP NW AS Java. However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. When using SNC to secure RFC destinations on AS ABAP the so called SNC System ACL, also known as System Authentication, is introduced and must be maintained accordingly. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. Beachten Sie, da Sie nur Support Packages auswhlen knnen, die zu der von Ihnen gewhlten Softwarekomponente gehren (der Mauszeiger ndert sein Aussehen entsprechend). To mitigate this we should look if it is generated using a fixed prefix and use this as a pattern with an ending wildcard in order to reduce the effective values, e.g., TP=Trex__*, which would still be better than TP=*`. To edit the security files,you have to use an editor at operating system level. This order is not mandatory. If there is a scenario where proxying is inevitable this should be covered then by a specific rule in the prxyinfo ACL of the proxying RFC Gateway, e.g.,: P SOURCE= DEST=internal,local. This list is gathered from the Message Server every 5 minutes by the report RSMONGWY_SEND_NILIST. The reginfo file is holding rules controlling which remote servers (based on their hostname/ip-address) are allowed to either register, access or cancel which 'Registered Server Programs' (based on their program alias (also known as 'TP name')). This is defined in, how many Registered Server Programs with the same name can be registered. In diesem Blog-Beitrag werden zwei von SAP empfohlene Vorgehensweisen zur Erstellung der secinfo und reginfo Dateien aufgefhrt mit denen die Security Ihres SAP Gateways verstrkt wird und wie der Generator dabei hilft. To control access from the client side too, you can define an access list for each entry. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. If you want to use this syntax, the whole file must be structured accordingly and the first line must contain the entry #VERSION=2 (written precisely in this format). This means that the sequence of the rules is very important, especially when using general definitions. Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. Example Example 1: this parameter controls the value of the default internal rules that the Gateway will use, in case the reginfo/secinfo file is not maintained. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. 3. With this rule applied you should properly secure access to the OS (e.g., verify if all existing OS users are indeed necessary, SSH with public key instead of user+pw). After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). The RFC Gateway can be used to proxy requests to other RFC Gateways. 2. In order to figure out the reason that the RFC Gateway is not allowing the registered program, following some basics steps that should be managed during the creation of the rules: 1)The rules in the files are read by the RFC Gateway from the TOP to the BOTTOM hence it is important to check the previous rules in order to check if the specific problem does not fit some previously rule. Thank you! RFCs between RFC clients using JCo/NCo or Registered Server Programs and the AS ABAP are typically controlled on network level only. Program cpict2 is allowed to be registered, but can only be run and stopped on the local host or hostld8060. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). Part 7: Secure communication Bei groen Systemlandschaften ist dieses Verfahren sehr aufwndig. If other SAP systems also need to communicate with it, using the ECC system, the rule need to be adjusted, adding the hostnames from the other systems to the ACCESS option. Its location is defined by parameter gw/prxy_info. RFC had issue in getting registered on DI. As a result many SAP systems lack for example of proper defined ACLs to prevent malicious use of the RFC Gateway. The reginfo file is holding rules controlling which remote servers (based on their hostname/ip-address) are allowed to either register, access or cancel which Registered Server Programs (based on their program alias (also known as TP name)). Someone played in between on reginfo file. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. The related program alias can be found in column TP Name: We can verify if the functionality of these Registered RFC Server programs is accessible from the AS ABAP by looking for a TCP/IP connection in transaction SM59 with Technical Settings Activation Type = Registered Server Program the corresponding Program ID and either no Gateway Options or connection details to any of the RFC Gateways belonging to the same system set: Please note: If the AS ABAP system has more than one application servers and therefore also more than one RFC Gateways there may be scenarios in which the Registered Server Program is registered at one specific RFC Gateway only. This is for clarity purposes. To use all capabilities it is necessary to set the profile parameter gw/reg_no_conn_info = 255. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. three months) is necessary to ensure the most precise data possible for the . where ist the hint or wiki to configure a well runing gw-security ? Check the above mentioned SAP documentation about the particular of each version; 4)It is possible to enable the RFC Gateway logging in order to reproduce the issue. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. If these profile parameters are not set the default rules would be the following allow all rules: reginfo: P TP=* Its location is defined by parameter 'gw/reg_info'. This would cause "odd behaviors" with regards to the particular RFC destination. All of our custom rules should bee allow-rules. In other words the same host running the ABAP system is also running the SAP IGS, for example the integrated IGS (as part of SAP NW AS ABAP) may be started on the application servers host during the start procedure of the ABAP system. Very good post. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. Zu jedem Lauf des Programms RSCOLL00 werden Protokolle geschrieben, anhand derer Sie mgliche Fehler feststellen knnen. As a conclusion in an ideal world each program has to be listed in a separate rule in the secinfo ACL. They are: The diagram below shows the workflow of how the RFC Gateway works with the security rules and the involved parameters, like the Simulation Mode. We solved it by defining the RFC on MS. This allows default values to be determined for the security control files of the SAP Gateway (Reginfo; Secinfo; Proxyinfo) based on statistical data in the Gateway log. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. Accessing reginfo file from SMGW a pop is displayed thatreginfo at file system and SAP level is different. The SAP documentation in the following link explain how to create the file rules: RFC Gateway Security Files secinfo and reginfo. Access to the ACL files must be restricted. This makes sure application servers must have a trust relation in order to take part of the internal server communication. Configuring Connections between SAP Gateway and External Programs Securely, SAP Gateway Security Files secinfo and reginfo, Setting Up Security Settings for External Programs. Of course the local application server is allowed access. The default configuration of an ASCS has no Gateway. . Wechseln Sie dazu auf die gewnschte Registerkarte (im Beispiel ist das Universen), whlen Sie Verwalten --> Sicherheit auf oberster Ebene --> Alle Universen (je nach Registerkarte unterscheidet sich der letzte Punkt). Please follow me to get a notification once i publish the next part of the series. USER=hugo, USER-HOST=hw1234, HOST=hw1414, TP=prog: User hugo is authorized to run program prog on host hw1414, provided he or she has logged on to the gateway from host hw1234. The Gateway is a central communication component of an SAP system. Part 4: prxyinfo ACL in detail. If someone can register a "rogue" server in the Message Server, such rogue server will be included in the keyword "internal" and this could open a security hole. three months) is necessary to ensure the most precise data possible for the connections used. The Stand-alone RFC Gateway: As a dedicated RFC Gateway serving for various RFC clients or as an additional component which may be used to extend a SAP NW AS ABAP or AS Java system. This publication got considerable public attention as 10KBLAZE. File reginfocontrols the registration of external programs in the gateway. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system.The secinfo file has rules related to the start of programs by the local SAP instance. Each instance can have its own security files with its own rules. Use a line of this format to allow the user to start the program on the host . Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. A LINE with a HOST entry having multiple host names (e.g. A general secinfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): Only the (SAP level) user IDs BOB and JOHN can start this program, and they will be logged on to one of the instances from this SAP system. This is because the rules used are from the Gateway process of the local instance. The RFC Gateway does not perform any additional security checks. Despite this, system interfaces are often left out when securing IT systems. The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. There is an SAP PI system that needs to communicate with the SLD. Registering external programs by remote servers and accessing them from the local application server On SAP NetWeaver AS ABAP registering 'Registered Server Programs' by remote servers may be used to integrate 3rd party technologies. With this rule applied for example any user with permissions to create or edit TCP/IP connections in transaction SM59 would be able to call any executable or script at OS level on the RFC Gateway server in the context of the user running the RFC gateway process. Part 3: secinfo ACL in detail This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. Save ACL files and restart the system to activate the parameters. Evaluate the Gateway log files and create ACL rules. In case of TP Name this may not be applicable in some scenarios. Systems are typically controlled on network level only a warning/info-message definiert werden Gateway.
