I am sure a LOT of people reading this blog use ssh in their everyday work\/life\/etc. I am not sure though how many of you have heard of ssh EscapeChar unless you’ve read the ssh_config file (and even if you have done so, did you pay any attention to it ?). So what can you do with EscapeChar ? not a lot, but certainly very usefull stuff.<\/p>\n

My most frequent problem with ssh is sessions that sometimes they don’t end as they are supposed to. You logout from the remote system and you never get a prompt on yours because something has stuck somewhere, sometime. Wouldn’t you wish there was an escape sequence to end this suffering, like telnet’s ctrl+] ? Well there is! Just edit your client’s ssh config file (\/etc\/ssh\/ssh_config for gentoo) and add to the end:
\nEscapeChar ~<\/code><\/p>\n

now try ssh to a host and when you are in, try this: ~?<\/code>. You will see a list of helpfull options. The solution to the previous described problem of stale connections is ~.<\/code>
\nDummy-safe: So to get it to escape press[alt gr] + [~] two times and then [.]<\/code>
\nIf that doesn\u2019t work, try pushing Enter before \u201c~\u201d.<\/p>\n

What’s also very helpfull is the ability to start\/end portforwarding during an active ssh session! Say you have opened an ssh connection to a host and you now have to portforward a port, what do you do ? New ssh connection with -L\/-R options ? nope! You just press ~C<\/code> and do what you want from the ssh “command shell”. <\/p>\n

enjoy!<\/p>\n","protected":false},"excerpt":{"rendered":"
