insert HTTP header according to a value received in Radius accounting
Hi, I'd like to know if the following is somehow achievable: I want that from Every Radius Accounting message (UDP 1813) the BIGIP will look for 3 attributes: Calling-Station-Id, Framed-IP-Address & Acct-Status-Type In case the Radius attribute Acct-Status-Type=1 (Start) the BIGIP will insert an entry to a table in which the key will be the Framed-IP-Address and the value will be the Calling-Station-Id. In case the Radius attribute Acct-Status-Type=2 (Stop) the BIGIP will remove the value of an entry in the same table (remove the value which is the calling-station-id assigned to the framed-ip-address) Then when HTTP transaction arrive from a client IP which appears as a key in the table, the BIGIP will insert the value assigned to that key in the table (i.e. the corresponding Calling-Station-Id) to an HTTP header called "MSISDN". Example: Radius accounting arrives with following attributes: Acct-Status-Type=1 Calling-Station-Id=123456789 Framed-IP-Address=1.1.1.1 An entry is inserted to a table 1.1.1.1 (key) -> 123456789 (value) HTTP request arrives from source IP 1.1.1.1 The F5 will insert a header "MSISDN: 123456789" to the HTTP request before forwarding. Radius accounting arrives with following attributes: Acct-Status-Type=2 Calling-Station-Id=123456789 Framed-IP-Address=1.1.1.1 The value is removed 1.1.1.1 (key) -> (empty) HTTP request arrives from source IP 1.1.1.1 The F5 will not insert a header (not "MSISDN: 123456789" and not "MSISDN: ") Hope it's clear. Thanks in advance, Yaniv
AS3 per-app JSON schema issue
Hello, I'd like to validate per-app declaration against vendor specific `per-app-schema` json schema file in vscode editor. Therefore I added there '$schema' object with valid schema file url, but it seems, that `$schema` object is not valid for per-app declaration. Here is my simple example (f5as3-ltm_app-based.cfg.yaml.as3.json file): { "$schema": "https://raw.githubusercontent.com/F5Networks/f5-appsvcs-extension/refs/heads/main/schema/3.56.0/per-app-schema.json", "schemaVersion": "3.54.0", "id": "urn:uuid:9ee77479-b1d9-5dfe-b0e6-bd1c65c10b8d", "controls": { "class": "Controls", "logLevel": "debug", "trace": true }, "app_test": { "class": "Application", "mon-tcp_test": { "class": "Monitor", "monitorType": "tcp", "remark": "AS3>app_test" } } } When I validate this file against per-app-schema.json it fails with this message: $ jsonschema -i f5as3-ltm_app-based.cfg.yaml.as3.json per-app-schema.json https://raw.githubusercontent.com/F5Networks/f5-appsvcs-extension/refs/heads/main/schema/3.56.0/per-app-schema.json: 'https://raw.githubusercontent.com/F5Networks/f5-appsvcs-extension/refs/heads/main/schema/3.56.0/per-app-schema.json' is not of type 'object' $schema: '$schema' does not match '^[A-Za-z][0-9A-Za-z_.-]*$' When '$schema' object is removed, validation using e.g. jsonschema is correct, but vscode can't validate edited file. I know, that I can map file to local schema file, but I'd like to use '$schema' object with url to vendor's schema file. It works for 'tenant-based' declaration (in vscode, also validation using e.g. jsonchema is correct): { "$schema": "https://raw.githubusercontent.com/F5Networks/f5-appsvcs-extension/refs/heads/main/schema/3.56.0/as3-schema.json", "class": "AS3", "action": "deploy", "persist": true, "declaration": { "class": "ADC", "schemaVersion": "3.56.0", "id": "urn:uuid:9ee77479-b1d9-5dfe-b0e6-bd1c65c10b8d", "updateMode": "selective", "tenant_test": { "class": "Tenant", "defaultRouteDomain": 0, "app_test": { "class": "Application", "mon-tcp_test": { "class": "Monitor", "monitorType": "tcp" } } } } } I checked per-app-schema.json file and it seems, '$schema' object is not valid configuration object - why? :) martin
iRule Developer Tools
Hi All, I've made a set of developer tools for Tcl including iRules, https://github.com/bitwisecook/tcl-lsp This includes LSP server Editor integrations for VSCode, Sublime Text, Zed, Jetbrains, Helix, neovim, emacs and more (though I've only really hammered on vscode there) MCP server Claude skills cli tool Semantic token highlighting Hover docs Format string interpreters AI tools for creating, explaing, validating, documenting, diagramming iRules and Tcl full optimising compiler chain with 26 optimiser passes 27 iRule specific diagnostics and optimisations Security warnings through taint tracking (use of user input tracked through the code) Shimmer detection with inline type hints (know when a variable type is being reinterpreted) Code formatting Code minification Compiler explorer to look at how your code is interpreted A full iRule testing framework and more. This is only based on publicly available information and my memory, though I have deployed enough iRules. This is the tool I always wanted. I could do with help expanding and improving the profile -> event / command maps, and the iRule event graph, and with generally finding bugs, so please, open issues. I will be away on holiday for a couple of weeks so please bear in mind I may take a little time to get back to you. cheers, Jim 🇬🇧🇦🇺
Create Domino LTPA token on F5 problem
Hi, I'm trying to use the code at http://per.lausten.dk/blog/2009/06/how-to-create-a-ltpa-session-cookie-for-lotus-domino-using-f5.html to create a Domino LTPA token but I am getting the following error showing on the Domino server: Token does not lead with 0 [Single Sign-On token is invalid]. The token should begin with the version number 0123 e.g. from the code set ltpa_version "\x00\x01\x02\x03" However, after decoding the token and then looking at it in a hex editor the version number shows as: C0 80 01 02 03 ....... Can somebody explain to me why the \x00 is being changed to C0 80 please? I've experimented putting other numbers in thefirst position to see what happens e.g. \x01\x01\x02\x03 and the hex readout looks correct i.e. 01 01 02 03. It only fails when I use a \x00 in the first position. Thanks for any suggestions. Jeff
Maintenance page - hosted on LTM or redirect with fallback host - or both?
I'm in the process of implementing an automated maintenance page that is displayed when I have a pool with no healthy members. Looking around, I see two distinct methods of doing this - utilizing the fallback host feature and redirecting to another url, or setting up a page to be hosted on the LTM and using an iRule with " [active_members [LB::server pool]] < 1" in it. Does anyone have any opinions on which one is preferred, and why? Currently, I'm using the fallback host method and I'm redirecting to a page hosted on AWS. My setup includes about 70 virtual servers on a 3600 HA cluster - some are QA, some are non-http. I will likley have the need for multiple versions of the maintenance page, depending on the site content it fronts. The one thing I do see as an advantage of the LTM hosted option is that an iRule code example shows a refresh option being used to automatically pull up the healthy site when it becomes available. Thanks!! ChrisRemoving port from a redirect
Hi all, One of our web developers has asked me if we could strip off a port number in a redirect they are doing. I thought the following would do this, but it doesn't appear to work. when HTTP_REPSONSE { if { [HTTP::is_redirect] } { if { [HTTP::header Location] contains "www.acme.com:10040" } { log "Original Location value: [HTTP::header Location]" HTTP::header replace Location [string map -nocase {www.acme.com:10400 www.acme.com} [HTTP::header value Location]] log "Updated Location value: [HTTP::header Location]" return } } } And here is what is written to the log Original Location value: www.acme.com:10040/secure/discussion-forum Updated Location value: www.acme.com:10040/secure/discussion-forum Note: actually the log includes http but if I enter in a URL in this new forum s/w it does odd things to it. Any help appreciated. Craig
Using a default persistence profile and iRule persistence on the same VS
I have an iRule applied to a VS that sends traffic to different pools based on its uri. I have a default persistence profile defined already on the VS (smsession) but on one of the pools I would like to use a different method of persistence (cookie). If I define the persistence to that pool in my iRule as shown below, which method of persistence is used in the end? Can you use a default persistence profile AND specify a different method using an iRule? when HTTP_REQUEST { set header_uri [string tolower [HTTP::uri]] if { [matchclass $header_uri starts_with $::www_uri] } { pool WWW_Pool } elseif { [matchclass $header_uri starts_with $::oam_uri] } { HTTP::redirect "https://oam.companyname.com/oam/main/oamMain.jsp" } elseif { [matchclass $header_uri starts_with $::cp_uri] } { persist cookie insert "CP_Cookie" "0d 03:00:00" pool CP_Pool } else { pool My_Pool } }
Wildcard SSL doesn't handle root domain?
My understanding of this may be lacking, but is there no way for a wilcard ssl certificate to handle the "root" domain? Example: I have a wildcard cert for "*.foo.com". It handles SSL requests as expected for "www.foo.com", but browsers will throw an identify verification error if the request went directly to "foo.com". Both https://www.foo.com and https://foo.com resolve to the same IP address/F5 Pool. That pool is using the wildcard cert (and works correctly with https://www.foo.com). Is this not a function of a wildcard SSL certificate? Thanks
