Telnet Proxy iRule
We would like an iRule that would accept a client connection on port 23, prompt the user for the desired destination (host name or IP), and then open an associated telnet session to an external host. ...
Well, we've got our base functionality working with this:
when CLIENT_ACCEPTED {
TCP::respond "Enter the IP address of destination site.\r\n"
TCP::collect 15
}
when CLIENT_DATA {
set ip "[TCP::payload]"
node $ip
TCP::release
}
It's not user friendly; they must enter IP addresses in XXX.XXX.XXX.XXX format (leading zeros when needed) and host names aren't supported, but it works. Next two steps: add SNAT for return routing and make the IP address input better. If all goes well, then add hostname support.
