[twsocket] SITE EXEC issue

2012-01-30 Thread Brian Culverwell
Hi

I have a client ftp component written using ICS and a server component also
using ICS - everything was grand up to about 2 weeks ago, when the client
ftp was sending a SITE EXEC progname to the server - now that command
never even gets received (and therefore never executes).  This smells of
anti-virus or something but it is just the SITE EXEC that does not work -
everything else is fine.

Regards
Brian

Unlikely to be anti-virus, more likely a firewall that is monitoring the
FTP control channel and removing the EXEC command.  

I had a similar problem with my Sonicwall monitoring FTP and it kept
interrupting an 8 gig download when it found a development tool it
considered malware.  I just added an exception to stop FTP being
monitored.

Use a sniffer - such as the free WireShark - see if it is a client side or
server side issue. Using the sniffer, you'll see if the client correctly
send the request or not. Then we may help you debug the client or server.
