Often you come across a situation where you try to open a machine remotely using ssh and try to start a server or a run a command indefinitely. But once you close the ssh session, your session also terminates and the background process also terminates. So here is a solution. To open ssh remotely, prompt $] ssh username@machinename Ex: ssh root@172.16.1.1 Ex: ssh root@example.com prompt $] ssh -X username @machinename Ex. ssh -X root@172.16.1.1 (this -X indicates the remote session can be opened in X window (GUI) mode) Assume we need to start a httpd server in the remote machine. we can issue the command like this usage: prompt$] nohup command if any error or log information may be stored in the nohup.out file. if you want to redirect to a file use the redirected symbol (1> indicates standard output and 2> indicates standard Error). Specify the filenames for the output. Here is the typical nohup command to start the httpd server. prompt $] nohup /etc/init.d/httpd start 1>
