SFTP Not Going Through Proxy Server

Post by hroman »

We have an SFTP that should be going through a proxy server by using ssh-proxyc. However, it does not appear to be executing this command because there are no packets going to the proxy server and the connection is failing.

I have the following in ssh_config:

Host *.ibm.com
Host *.emc.com
ProxyCommand ssh-proxyc -v -p gateway2ndc.ual.com:1080 %h %p
ProxyUseFDpass yes
Protocol 2

The msg's from the SFTP sysout are:
