NimbostratusI could not find the configuration guide, but it was communicated to me that the list of disabl;ed commands is on the Wiki.
http://devcentral.f5.com/wiki/default.aspx/iRules/DisabledTclCommands.html
I find it frustrating that when I searched earlier in the iRule Wiki for this search string:
"disabled tcl commands"
That the search turned up nothing.
After being visually pointed to the diabled TCL commands on the Wiki, and saw the wiki name of "DisabledTCLCommands", I can search for that exact string:
"DisabledTCLCommands"
And this returns results.
Why does the wiki search have this problem?
Should the wiki try and find results that match any part of the sentence string, and not restrict the search to only an exact match.
Anyway, disabling "open" and "exec" TCL commands disallows communication to an external application on the system from an iRule. How can I get around this restriction? How can I communicate with a system application?
