How to FTP from specified interface?

Maxim Yakimenko — Tue, 25 Dec 2007 08:48:46 GMT

Hi, collegues

Server is cluster node. On his physical interface lan0 there are his own IP and virtual cluster IP (interface lan0:1), also on server there is interface for cluster heartbeat. When I try to ftp to another server is says "connection refused". When I telnet to it on 21 port it opens connection. I suspect that reason of this problem is the way of interface selection by FTP-client - it standard ftp tool, HP-UX 11.23. Any suggestions?

"connection refused" normally means that you
can talk to the other system, but that the
requested server (here, FTP) is not available
there. Can _any_ system (including itself)
get to the FTP server on that system?

could you post the output of following from the cluster server

"telnet ftpserver 21"

and "netstat -an|grep LISTEN|grep .21" from the target/ftp server

Thank you for your replies. I have found what's wrong. Due to one reason I need to start ftp server on that machine on port differ than 21. And I forget it. Deeper investigation helped :)

Make that "not available there on the port
requested." (Everything's complicated.)
