I've been testing FTP service through our CSM for about a day now and has run into an issue I can't find an answer for.
Here are the settings I'm currently using for the vserver and serverfarm. The 10.90.1.0 network is routed from my client network by a firewall using NAT.
no nat client
virtual 10.90.1.40 tcp ftp service ftp
Connecting to the FTP works just fine using both passive and active FTP and I can log in and transfer files. However when I send the "quit" command to the FTP server, as I do when connecting to the server directly, the session freezes and the "good bye" messages never appears.
My guess is that there is some premature termination of the connection before a final disconnect is sent to my FTP client. Anyone have an idea how this can be solved?
Re: FTP service through CSM: Quit command not working
Ethereal sniffer trace on the CSM port channel included. What I can see from the trace the Quit message is transmitted by the FTP/VIP but not forwarded by the firewall. Strange, I you have another interpretation please let me know.
I've tried L2 FTP using the VIP as loopback on the FTP server but couldn't get it to work with both active and passive FTP.
Moquery is the command line cousin of Vizore, it's very helpful and efficient sometimes during the troubleshooting. This article aims to provide moquery cheat sheet to the users for some most common seen scenarios.
