Can someone explain why SSH duplicates stdin back to to the screen when PTY allocation is forced and how I can disable it?
~% ssh -V
OpenSSH_5.5p1 Debian-6+squeeze2, OpenSSL 0.9.8o 01 Jun 2010
~% echo "This should only show up once." | ssh server.tld -tt '/bin/cat'
This should only show up once.
This should only show up once.
I have a server that we'll call hub-server.tld with three IP addresses 100.200.130.121, 100.200.130.122, and 100.200.130.123. I have three different machines that are behind a firewall, but I want to use SSH to port forward one machine to each IP address. For example: machine-one should listen for SSH on port 22 on 100.200.130.121, while machine-two should do the same on 100.200.130.122, and so on for different services on ports that may be the same across all of the machines.
The SSH man page has -R [bind_address:]port:host:hostport listed I have gateway ports enabled, but when using -R with a specific IP address, server still listens on the port across all interfaces:
# ssh -NR 100.200.130.121:22:localhost:22 [email protected]
# netstat -tan | grep LISTEN
tcp 0 0 100.200.130.121:2222 0.0.0.0:* LISTEN
tcp 0 0 :::22 :::* LISTEN
tcp 0 0 :::80 :::* LISTEN
Is there a way to make SSH forward only connections on a specific IP address to machine-one so I can listen to port 22 on the other IP addresses at the same time, or will I have to do something with iptables? Here are all the lines in my ssh config that are not comments / defaults:

Are there any revision control systems (git preferred) that could run on shared hosting server presumably by being launched as CGI scripts?
On Windows XP through 7, I have a service that needs to be able to launch sub-processes as other users. Executing runas would do the trick, but SYSTEM is not configured to use runas without a password for the accounts. Can SYSTEM be configured to be able to authenticate as users without needing a password?
