I understand that I can forward multiple port in ssh config file by:
Host name HostName yam.myHost.edu User myUserName LocalForward 5901 127.0.0.1:5901 LocalForward 5902 127.0.0.1:5902 [...] LocalForward 5910 127.0.0.1:5910 Is there any easier way to forward a range of ports without the need to add extra line for a port? Something like LocalForward 5901-5910 127.0.0.1:5901-5910 ?
I'm doing this usually without config, interactively in the command line like this
ssh yam.myHost.edu $(for i in `seq 5901 5920` ;do echo -L $i:localhost:$i ;done) You could also generate the config file lines and copy/paste it to your config file:
for i in `seq 5901 5920` ;do echo "LocalForward $i localhost:$i" ;done LocalForward 5901 localhost:5901 LocalForward 5902 localhost:5902 LocalForward 5903 localhost:5903 [...] Short answer is no.
SSH does not support "range" for port forwarding. It can be somehow achieved by having a more complex setup that forwards only 1 port and a proxy on both ends will act as a router the selects the right local port, but I guess this is far from what you need.
The most convenient way is to provide multiple LocalForward lines in your config (which can be created dynamically with a small script). Also note that the SSH command accepts multiple -L arguments for multiple ports, so the following works:
ssh user@host -L 8000:localhost:8000 -L 8001:localhost:8001
What you can do is setup an alias that performs 1 ssh connection for all of the ports you need.
configa socket and feeding its contents dynamically, or making.ssha virtual file system, or any such extremes. It certainly takes more than "a function")DynamicForwardoption insshd_config.
