Iterm2 keep ssh session alive2/18/2023 ![]() ![]() It may be worth filing a bug report or contacting the author if you're still having problems. Perhaps you can modify the code to force the first block to always run, regardless of theTerm's contents. The screen documents refer to this sequence with C-a. For example, to detach from the session, you will have to press Ctrl + a, and then press d. Any character followed by this sequence is interpreted as a command to screen. After all, tmate is a multiplexer, so it should be able to keep sessions alive, detach and re-attach. sharing your terminal with a different console application. If there is no response from the client, the session is suspended until the client reconnects. The key binding prefix for screen is Ctrl + a. Linux and Mac OS X operating systems With this configuration, the SSH client sends a packet to the server every 240 seconds (4 minutes) to keep the connection. The keep - alive messages are used to detect whether the client is still responsive. I suspect that when theTerm = nil, addNewSession works as expected by launching a new window, since one is currently not running. Once you hit screen, you are inside a screen session. WindowType: ? intValue] : WINDOW_TYPE_NORMAL If you want to set the keep alive for the server, add this to /etc/ssh/sshdconfig: ClientAliveInterval 60 ClientAliveCountMax 2 ClientAliveInterval : Sets a timeout interval in seconds after which if no data has been received from the client, sshd(8) will send a message through the encrypted channel to request a response from the client. A logfile can be read back easily with cat, e.g., cat foo.log. To automate this for all sessions of a given profile e.g., Default: Preferences > Profiles > Default > Session > Automatically log session input to files in. In most cases, the client configuration needs to be set to a lower value than the default timeout of the server. To enable session logging for a single session: Session > Log > Start. This is usually due to a network disconnect between the client and the server. The configuration for this is in the file HOME/. On lines 789 to 870 the launchBookmark:withURL method has the following code: // Where do we execute this command? If it goes through the ClientAliveInterval twice without getting a signal back from the client, the server will close the SSH session. To prevent connection loss, instruct the ssh client to send a sign-of-life signal to the server once in a while. How To Enable Shell Integration The easiest way to install shell integration is to select the iTerm2>Install Shell Integration menu item. My Xcode and Objective-C skills are still rather weak, but if you want to give it a shot I believe the problem is related to the source file iTermController.m. iTerm2 may be integrated with the unix shell so that it can keep track of your command history, current working directory, host name, and moreeven over ssh. ![]() After reviewing the source code, I found in iTerm2 v1.1020 is hard-coded to open a new session as a tab if a session already exists, when it receives nearly any "launch this URL with a handler" command. ![]()
