It doesn’t matter if the packet is sent from the client or the server, as long as there is some communication going. ITERM2 KEEP SSH SESSION ALIVE HOW TOProtocolKeepAlives and SetupTimeOut are Debian-specific compatibility aliases for this option. Here’s how to keep your SSH sessions alive and prevent the SSH timeout: By sending a null packet between the client and the server at a specified interval that is smaller than the timeout value, we can avoid SSH timeout. This option applies to protocol version 2 only. Fixed: Multiplexer sessions would fail to bootstrap via ssh because the. The default is 0, indicating that these messages will not be sent to the server, or 300 if the BatchMode option is set. 843 Fixed: dont keep the window alive after running something & disown. Sets a timeout interval in seconds after which if no data has been received from the server, ssh(1) will send a message through the encrypted channel to request a response from the server. This option applies to protocol version 2 only in protocol version 1 there is no mechanism to request a response from the server to the server alive messages, so disconnection is the responsibility of the TCP stack. If, for example, ServerAliveInterval (see below) is set to 15 and ServerAliveCountMax is left at the default, if the server becomes unresponsive, ssh will disconnect after approximately 45 seconds. The server alive mechanism is valuable when the client or server depend on knowing when a connection has become inactive. The TCP keepalive option enabled by TCPKeepAlive is spoofable. The server alive messages are sent through the encrypted channel and therefore will not be spoofable. It is important to note that the use of server alive messages is very different from TCPKeepAlive (below). ITERM2 KEEP SSH SESSION ALIVE SOFTWAREIf you connect to multiple servers via SSH, set it on. Keep ssh in terminal alive via cron job So hello Recently I installed a special server software on a Ubuntu server - its originally Windows but doesnt seem to run on any windows after win2000 since its a pre 2000 software I installed it on a Ubuntu server and ran it with x11 via wine but I have to keep a infinite active connection. Either you send the alive message from the client to the server or from the server to the client. ssh / config The above command will create the configuration file and open the file in the nano editor to let you edit it even if it does not exist. If this threshold is reached while server alive messages are being sent, ssh will disconnect from the server, terminating the session. This way, you keep the SSH session alive because there is a communication between the client and server and the server understands that client is still there. Keep a Terminal Session Alive by Setting Up the Configuration File To edit the configuration file of SSH, type the command given below: sudo nano HOME/. Sets the number of server alive messages (see below) which may be sent without ssh(1) receiving any messages back from the server. From the ssh_config man page: ServerAliveCountMax: It would be great to use another method besides send an ascii character to keep the sessions alive.
