most of our servers have timeout for ssh connections or probably the routers or firewalls configured to cut the connections if no data is transferred in either direction after a certain time interval, basically by the time i came back from lunch, all ssh connections will be disconnected. sucks right?
there are 2 ways to prevent this to happen. either do it from the servers or clients side.
1st way: reconfigure sshd on the servers like this:
edit
/etc/ssh/sshd_config put
ClientAliveInterval 60and don’t forget to restart sshd on the server;)
2nd way: if you have a bunch lot of servers, i bet you don't want to edit all the servers configs. the easier way is to configure on the client end.
- if your're using
linux desktop edit
/etc/ssh/ssh_config and add the line:
ServerAliveInterval 60- if you're using
putty - under
Connection, put non-zero value for
:
Seconds between keepalives (0 to turn off). eg.
60- if you're using
cygwin edit
~/.ssh/config and add these lines:
Host *
TCPKeepAlive no
ServerAliveInterval 60or u just can put below options when execute ssh command:
$ ssh
-o TCPKeepAlive=no -o ServerAliveInterval=60 servername
oh btw, i've dumped
putty + PuTTY Connection Manager, now using cygwin +
puttycyg.
with puttycyg, at least u're not stuck with the crap "cmd.exe" windows that comes with cygwin, unless u install Cygwin/X lor. betul dak jep?
1 more thing, ssh to outside world is block from within our company network. here is the trick - reconfigure your sshd to run on port 443. on cygwin install
corkscrew, then put these in the
~/.ssh/config
Host outside_server
ProxyCommand corkscrew your_company_proxy_ip 8080 %h 443
$ ssh outside_serverPassword:walla you're now on outside world!
again, if u're using putty - under
Connection -
Proxy. oh thanks to apai!
