Advanced WAF IP Exceptions Manager
This solution introduces a dedicated Python-based GUI tool for managing IP whitelist exceptions in F5 BIG-IP Advanced WAF policies. The tool was developed to simplify a common operational workflow: searching WAF policies, adding IP or CIDR-based exceptions, checking whether an IP already exists across policies, deleting outdated exceptions, applying policy changes, and tracking actions through an activity log. The solution is especially useful in large environments where manual exception handling can create operational overhead, inconsistent policy configuration, or audit challenges. It demonstrates how focused automation can deliver practical value without requiring a large orchestration platform or full CI/CD pipeline.BIG-IP Report
Problem this snippet solves: Overview This is a script which will generate a report of the BIG-IP LTM configuration on all your load balancers making it easy to find information and get a comprehensive overview of virtual servers and pools connected to them. This information is used to relay information to NOC and developers to give them insight in where things are located and to be able to plan patching and deploys. I also use it myself as a quick way get information or gather data used as a foundation for RFC's, ie get a list of all external virtual servers without compression profiles. The script has been running on 13 pairs of load balancers, indexing over 1200 virtual servers for several years now and the report is widely used across the company and by many companies and governments across the world. It's easy to setup and use and only requires auditor (read-only) permissions on your devices.

APM SAML IdP - SP Issuer Extraction
Problem this snippet solves: APM doesn't expose any detail about the SAML SP Issuer when authentication requests hitting APM as an IdP during an SP initiated SAMLRequest. This iRule when applied to a SAML IdP enabled virtual server will extract the assertion request, decode it and present the SAML SP Issuer ID as the session variable %{session.saml.request.issuer} within APM. How to use this snippet: This comes in real handy when performing authorisation of the resource and could help avoid having APM perform a TCP connection reset when a SAML resource isn't authorised. Code : when CLIENT_ACCEPTED { ACCESS::restrict_irule_events disable } when HTTP_REQUEST { if { [HTTP::path] equals "/saml/idp/profile/redirectorpost/sso" } { if { [HTTP::method] equals "POST" } { # Colelct POST data set content_length [HTTP::header value Content-Length] HTTP::collect $content_length } elseif { [HTTP::method] equals "GET" } { #TODO } } } when HTTP_REQUEST_DATA { set payload_data [URI::decode [HTTP::payload]] log local0. "payload=[URI::query "?$payload_data" "SAMLRequest"]" if { $payload_data contains "SAMLRequest" } { # Extract SAML request data set SAMLdata [b64decode [URI::query "?$payload_data" "SAMLRequest"]] set SAML_Issuer_loc [string first "saml:issuer" [string tolower $SAMLdata]] set SAML_Issuer_start [expr {[string first ">" $SAMLdata $SAML_Issuer_loc] + 1}] set SAML_Issuer_end [expr {[string first "<" $SAMLdata $SAML_Issuer_start] - 1}] set SAML_Issuer [string range $SAMLdata $SAML_Issuer_start $SAML_Issuer_end] if { !([ACCESS::session sid] equals "" ) } { ACCESS::session data set session.saml.request.issuer $SAML_Issuer } } } when ACCESS_SESSION_STARTED { if { [info exists SAML_Issuer] } { ACCESS::session data set session.saml.request.issuer $SAML_Issuer } } Tested this on version: 11.6
Creating a tmsh script with iControl REST and using it to restart HTTPD
Problem this snippet solves: TMSH has the ability to create tcl scripts that can be used to run multiple commands and transactions. It is rare that you will want to create on with TMSH but there are a few cases where this may be desirable. One of these is to restart HTTPD, which is difficult to do from iControl REST because the REST API is running over HTTPD and the restart will not be clean. See K13292945. This Python script creates a tmsh script, and then runs it to restart HTTPD. How to use this snippet: Syntax is <program_name.py> host user password Sample output: ./rest_script_example.py 10.155.117.12 admin admin Before httpd (pid 3186) is running...

FTP Session Logging
Problem this snippet solves: This iRule logs FTP connections and username information. By default connection mapping from client through BIG-IP to server is logged as well as the username entered by the client. Optionally you can log the entire FTP session by uncommenting the log message in CLIENT_DATA. Code : # This iRule logs FTP connections and username information. # By default connection mapping from client through BIG-IP to server is logged # as well as the username entered by the client. Optionally you can log the # entire FTP session by uncommenting the log message in CLIENT_DATA. when CLIENT_ACCEPTED { set vip [IP::local_addr]:[TCP::local_port] set user "unknown" } when CLIENT_DATA { # uncomment for full session logging #log local0.

Code version: The code was tested on 17.1.5.3 AS3: 3.55 For more about AS3 and per-app AS3 see my previous code share Part 1 article: https://community.f5.com/kb/codeshare/f5-per-app-as3-part-1-how-share-tenant-specific-object/345072 First we will send Per-App AS3 declaration as shown below. { "id": "per-app-declarationn", "schemaVersion": "3.55.0", "controls": { "class": "Controls", "logLevel": "debug", "trace": true, "traceResponse": true }, "A2": { "class": "Application", "service": { "class": "Service_HTTP", "virtualAddresses": [ "10.0.3.10" ], "pool": "web2_pool" }, "web2_pool": { "class": "Pool", "monitors": [ "http" ], "members": [{ "servicePort": 80, "serverAddresses": [ "192.7.21.10", "192.7.21.11" ] }] } } } Then we will change for example virtual server ip from 10.0.3.10 to 10.0.3.11 and we will send the same declaration but with "dryRun" set to true as this will cause AS3 to validate the config but not to execute it and with trace and traceResponse we will get the difference 😎 { "id": "per-app-declarationn", "schemaVersion": "3.55.0", "controls": { "class": "Controls", "logLevel": "debug", "trace": true, "dryRun": true, "traceResponse": true }, "A2": { "class": "Application", "service": { "class": "Service_HTTP", "virtualAddresses": [ "10.0.3.10" ], "pool": "web2_pool" }, "web2_pool": { "class": "Pool", "monitors": [ "http" ], "members": [{ "servicePort": 80, "serverAddresses": [ "192.7.21.10", "192.7.21.11" ] }] } } } Now we see that the IP has been changed from 10.0.3.10 to 10.0.3.11 and here we go now we have the difference ! This can be added in CI/CD to always first do "dry-run" using the original declaration to see if there are changes before executing the new AS3 declaration that could be for example changing the IP address to 10.0.3.12 but using the official way. Look at the Json reply "diff" section that is seen thanks to trace and traceResponse options and an automation can just check this section and stop the new deployment if the manual changes need to be reviewed first. For AS3 basic declaration not Per-App actually the "dry-run" is a different. F5 likes changing the naming like Local Traffic policies to Endpoint Policies or naming of TLS profiles between GU/TMSH and AS3 😅 { "$schema": "https://raw.githubusercontent.com/F5Networks/f5-appsvcs-extension/refs/heads/main/schema/3.55.0/as3-schema.json", "class": "AS3", "action": "dry-run", "logLevel": "debug", "trace": true, "traceResponse": true, "persist": true, "declaration": { "class": "ADC", "schemaVersion": "3.55.0", "id": "BIG-IP-Example-Tenant", "Example": { "class": "Tenant", "Shared": { "class": "Application", "template": "shared", "Example_Response": { "remark": "Used for F5 response", "class": "iRule", "iRule": { "base64": "d2hlbiBIVFRQX1JFUVVFU1Qgew0KICAgSFRUUDo6cmVzcG9uZCAyMDAgY29udGVudCB7DQogICAgICA8aHRtbD4NCiAgICAgICAgIDxoZWFkPg0KICAgICAgICAgICAgPHRpdGxlPkFwb2xvZ3kgUGFnZTwvdGl0bGU+DQogICAgICAgICA8L2hlYWQ+DQogICAgICAgICA8Ym9keT4NCiAgICAgICAgICAgIFdlIGFyZSBzb3JyeSwgYnV0IHRoZSBzaXRlIHlvdSBhcmUgbG9va2luZyBmb3IgaXMgdGVtcG9yYXJpbHkgb3V0IG9mIHNlcnZpY2U8YnI+DQogICAgICAgICAgICBJZiB5b3UgZmVlbCB5b3UgaGF2ZSByZWFjaGVkIHRoaXMgcGFnZSBpbiBlcnJvciwgcGxlYXNlIHRyeSBhZ2Fpbi4NCiAgICAgICAgIDwvYm9keT4NCiAgICAgIDwvaHRtbD4NCiAgIH0NCn0=" } } } } } } This will not show if someone has manually added a vlan for example as only changes on the apps that were deployed with AS3 will be seen.

Code version: The code was tested on 17.1.5.3 AS3: 3.55 For testing F5 AS3 you can use combination of Postman as Visual Studio has option to post AS3 declarations but not Per-App specific as that will be needed for executing my code. Still I recommend using Visual Studio for general AS3 or Fast Templates and you can use the reference links for how to use Visual Studio F5 extensions and maybe F5 will update the extension in the future to work for Per-App AS3 with options for adding tenant and as variables 🤔 For FAST nice example is at https://github.com/Nikoolayy1/fast-template-examples The same way the /Shared objects can be configured under /Common can be done under a specific tenant and this is really useful if Per-App AS3 is enabled as each AS3 app will use separate declaration and all of them can use a customer iRule defined under /<Tenant>/Shared.

Weblogic JSessionID Persistence
Problem this snippet solves: Contributed by: unRuleY, Summarized by: deb Note: The previous version of this iRule contained escaped newlines following the session command, which in versions 10.0 - 10.2.0 causes TMM to core as documented in CR135937 / SOL11427. This was fixed in 10.2.1. See this related Codeshare example for details on how to take advantage of session replication on the WebLogic servers with targeted node failover in an iRule. Provides persistence on the jsessionid value found in either the URI or a cookie. When a request is received, the iRule first looks for a "jsessionid" cookie, and if not found, for a "jsessionid" parameter in the requested URI. If either is found, a persistence record is created if it doesn't already exist, or followed if it does. If neither is found, the request is load balanced according to the load balancing method applied to the virtual server and persisted based on the client's IP address. In order to ensure the second and subsequent requests follow the first, LTM must create a persistence record indicating the pool member to which the first request was load balanced. If the server is setting the jsessionid in a cookie, the persistence key value may be extracted from the server response to create the persistence record. If the server is setting the jsessionid in the URLs, source address persistence with a short timeout is recommended to track the original destination until the jsessionid is sent. How to use this snippet: To ensure a new persistence record is followed when a request is re-load balanced in a client-side Keep-Alive connection, apply a OneConnect profile to the virtual server. The iRule assumes the jsessionid is in upper case when used as a cookie name. If this isn't the case, please update the example. To persist on jsessionid, create the iRule below and create a custom Universal persistence profile, with Match Across Services enabled, that uses the iRule. Then use this custom Universal persistence profile as the Default Persistence profile on your Virtual Server. Applying a Fallback Persistence profile of type Source Address Affinity with a host mask and a short timeout (the default source_addr persistence profile will do the trick) to your Virtual Server is also recommended. Attention, if you are running firmware 11.0 - 11.2.1 and enabled "Match Across Services"! There is a bug inside. SOL14061 This iRule requires LTM v10. or higher.

Code is community submitted, community supported, and recognized as ‘Use At Your Own Risk’. Short Description A tool that makes developing logstash pipelines much much easier. Problem solved by this Code Snippet Oh. The problem... Have you ever tried to write a logstash pipeline? Did you suffer hair loss and splitting migraines? So did I. Presenting, logstash pipeline tester which gives you a web interface where you can paste raw logs, send them to the included logstash instance and see the result directly in the interface. The included logstash instance is also configured to automatically reload once it detects a config change. How to use this Code Snippet TLDR; Don't do this, read the manual or checkout the video below Still here? Ok then! 🙂 Install docker Clone the repo Run these commands in the repo root folder:sudo docker-compose build # Skip sudo if running Windows sudo docker compose up # Skip sudo if running WindowsGo to http://localhost:8080 on your PC/Mac Pick a pipeline and send data Edit the pipeline Send data Rince, repeat Version info v1.0.27: Dependency updates, jest test retries and more since 1.0.0 https://github.com/epacke/logstash-pipeline-tester/releases/tag/v1.0.29 Video on how to get started: https://youtu.be/Q3IQeXWoqLQ Please note that I accidentally started the interface on port 3000 in the video while the shipped version uses port 8080. It took me roughly 5 hours and more retakes than I can count to make this video, so that mistake will be preserved for the internet to laugh at. 🙂 The manual: https://loadbalancing.se/2020/03/11/logstash-testing-tool/ Code Snippet Meta Information Version: Check GitHub Coding Language: NodeJS, Typescript + React Full Code Snippet https://github.com/epacke/logstash-pipeline-tester
