SSH/SFTP Disrupted by Untangle Security Appliance

(With permission from a Chilkat customer, for the benefit of others..)


We did some extensive testing and found that our client sees this on their end what the connection fails:

SERVER:   13.07.2010  15:21:43  (57220) session ended on error, Buffer missing (error 132).

Do you know what that could possibly mean in relation to Chilkat’s SFTP?


“The issue ended up being a security appliance (Untangle) we had. We added a bypass rule in there for port 22 and it went from working 3/5 times to 5/5 times.”
