FTP partially blocked-- how to trace?

Hello,

I use various programs to such as Ultraedit to upload files via FTP.
On one site, all of a sudden I began having a mysterious problem. I
can log onto the site, but I cannot do anything alse. I am able to get
the name of the directory I am in but I can't get any other directory
information, change directories or access any files.

I am only having this problem on one site. All my programs, smartFTP,
WSFTP, HtmlKit , NVU were effected at the same time, except WinSCP
which still works fine. The Server tech had changed some firewall
settings but has been unable to figure out what the problem is. I'm
still suspect it has something to do with the firewall settings on the
server. It only seems to effect my account, It doesn't make a
difference if I use passive or not passive, or if I take down all
firewalls on my end. I double checked that it is not something on my
computer by using another computer, albeit from the same location. It
had the same problem.

Here is one attempt by htmlKit, in non passive mode:

HtmlKit:
FTP > PWD
FTP < 257 "/home/trt/www/html/website.com" is your current location
FTP > PORT 192,168,1,101,4,110
FTP < 500 Unknown command
FTP > 500 Unknown command
FTP - Could not get directory list. (933)
FTP > CWD /home/trt/www/html/website.com
FTP < 250 OK. Current directory is /home/bvb/www/html/website.com

Any Idea what it could be ?

I had the idea that if I could possibly see the requests that WinSCP
and UltraEdit send to the server, I could compare them and and
possibly see what is working and what is not. If it were http traffic,
I would use Charles http://xk72.com/ an HTTP proxy / HTTP monitor. Is
there an FTP equivilant ?

Thanks.
