![]() ![]() You can create a Windows Terminal profile that does this on startup by adding the commandline setting to a profile in your settings.json file inside the list of profile objects. You can start an SSH session in your command prompt by executing ssh and you will be prompted to enter your password. There is some danger that cu is willing to absorb certain signals without quitting, or that it will crash uncleanly (perhaps leaving the serial port in a messed-up state, or leaving log files not updated).Windows Terminal version 1.XX+ can dynamically generate profiles to connect to the SSH hosts within your OpenSSH config file. If all else fails, google for hints, or read the source to cu. You may have to experiment with what signal to send (common candidates are QUIT, KILL, TERM, USR1). If you want to 'navigate' through the server, you will have to use commands like cd (change directory), ls (list), cp (copy) and so on. Open a second window to the same host, and use the kill command in the second window. What you are seing is the prompt, meaning the way the server let's you interconnect with it. But to be honest, I don't remember which signal that is, and the documentation is silent on it. Option 3: I think there is a signal that you can send to cu to make it quit. ![]() Again, there aren't terribly many possible choices. That's easier, use option -e on the ssh command line. Option 2: Change the escape character that ssh uses. ![]() It may take some effort to find another rarely-used character, like backslash or vertical bar or backquote. It's the variable "escape" in the cu configuration file. Option 1: Change the escape character that cu uses. Your problem is that both cu and ssh use the same escape character, namely tilde or "~". Re: Closing cu from within an ssh session? What is the proper way to shutdown and exit out of a cu session?Īnd what is the proper way to do it from within an ssh session? I need to close down cu properly, within the original ssh session I opened it from. And if someone else tries to access the port it's busy. ClientAliveInterval is a timeout interval specified in seconds. Notice this keyword uses Client in it instead of Server like we saw in the earlier examples. Now we add the ClientAliveInterval keyword to the config file using nano. If I use " ~!" it drops me back into my ssh session, but the lock is still in place. First, the file location of the server-side config file is /etc/ssh/sshdconfig. On Ubuntu 22.04 the config file is /etc/ssh/sshdconfig. Hitting the esc key a bunch of times followed by a quick " shift+~" will do it.īut, if I do it while ssh'd to host_b it closes the ssh session. The first one configures the server to send null packets to clients every 120 seconds and the second one configures the server to close the connection if the client has been inactive for 720 intervals that are 720120 86400 seconds 24 hours. Sometimes it registers a literal " ~" character, other times it registers as an escape signal. ![]() The normal way to close down cu to cuau0 is keystroke " ~." or " ~^d", the " ~" is an escape signal, followed by a command. I need to be able to shut down and exit out of the cu session on cuau0, during the ssh session I opened it from. Host_b has a serial line to a network device on /dev/cuau0įrom host_a, through my ssh session, I can use cu-> cuau0 -> network device.Įverything works as expected/intended up to this point.īut then, if I want to close down the serial connection without closing my ssh session. ![]()
