How to set default session timeout in Linux<\/a><\/h1>\n
\n<\/div>\n<\/header>\n
\n

My DC operation guys access Linux servers on a daily basis but somehow they never remember to log out. This is a security risk as anyone could gain access to the open console and create caos.<\/p>\n

Today, yet again I\u2019m forced to play the bad guy by dummy proofing my Linux servers by implementing default timeout for user sessions.<\/p>\n

Bash and Korn both support the TMOUT variable which I will use to set the default timeout.<\/p>\n

The etc\/.bashrc file will apply the timeout system wide but if you need it to be user specific then modify the ~\/.bashrc file instead.<\/p>\n

Here\u2019s how it\u2019s done.<\/p>\n

echo \"TMOUT=300 >> \/etc\/bashrc<\/code><\/pre>\n
echo \"readonly TMOUT\" >> \/etc\/bashrc<\/code><\/pre>\n
echo \"export TMOUT\" >> \/etc\/bashrc<\/code><\/pre>\n
Log off, start a new session and wait for 5 minutes. Your session should terminate<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
