Solutiontelnet ftpserver 21
If you get answer, at least port 21 is open. If you can connect, but you cant issue commands or they hangs, then the problem is that port 20 is blocked. Use passive mode.

Re: Firewall and ftp
The architecture is that i am working on a mediation application that gets the files from the switches in the network for billing,now the application would wait for some time for the switch to respond,but now the ftp timeout period expires and the files are not ftp'd from the switch.the protocol used is XFERRBF.

Re: Firewall and ftp
You might try tracing the packets of a (sucessful) interactive session compared to an (unsuccessful) non-interactive session.
Here are the commands:
# pfconfig +p +c
# tcpdump -i
# tcpdump -i
# pfconfig -p -c
This will create two files - outfile1 and outfile2 - containing the packets exchanged between your server and the FTP server. You can use 'tcpdump -r
