FTP Proxy , user based forwarding with iRule
Im looking into using a VS as an FTP Proxy towards my backend webserver. Currently i already works for one webserver behind the VS.
Im now trying to write an iRule to forward traffic to the right s...
So currently i can redirect traffic to the right server based on username.
But the username gets modified when sending it to the server from F5 somehow. I use following to change the tcp::payload
TCP::payload replace 0 [TCP::payload length] ""
set packetdata "USER $user"
TCP::payload replace 0 0 $packetdata
serverside we see the following
[pid 31210] FTP command: Client "::ffff:10.1.1.1", "USER usernameSYST"
when i log tcp::payload on F5 i see "USER username". So i have no idea where the SYST part comes from
