How to close other active session on putty running on another computer?

Question

我正在尝试关闭在其他计算机上运行的腻子会话。

Answer 1

You kill the process ID of the user's login session:

kill -9 12345

Try running the w command and looking at the output. Something like:

w | grep ssh 

will show all users connected via ssh . More scripting and automation is possible to help you narrow down the process ID of the login session:

pgrep -u w | grep ssh| awk '{print $1}' w | grep ssh| awk '{print $1}' w | grep ssh| awk '{print $1}' ssh

will give you a list of numbers that are the PID s of the login session. You can then use ps to verify that this is the session you want to kill . See the kill(1) , ps , and pgrep manual pages.

You can get fancy and make a script or shell alias to print the users and their ssh sessions (NB: quick hack for illustration, not portable):

for u in `w| grep ssh|awk '{print $1}'`
do 
  echo -e "\n"$u
  pgrep -x -l -u $u ssh
done

... and other variation on this theme. If you are killing sessions this way oftne it's a good idea to have a script or tool that helps you identify the correct session before your kill -9 it - especially on a busy shell login host. Even more useful are tools that are cross platform and/or POSIX -ish ( w who ps etc. vary slightly in their output formats). That kind of tool can be written in perl , ruby or very careful sh and awk .
