On UNLV CS servers you have a limited number of processes that you can create. Once you have exceeded that number, you will not be able to remotely log in.
Finding a process
Find the process ID (PID) by typing
ps -ef | grep username
You will see output like this
UID PID PPID C STIME TTY TIME CMD janedoe 2233 2231 0 16:57 ? 00:00:00 /usr/sbin/sshd janedoe 2234 2233 0 16:57 pts/0 00:00:00 -sh janedoe 2254 2234 0 16:57 pts/0 00:00:00 ps -ef janedoe 2255 2234 0 16:57 pts/0 00:00:00 grep janedo
Killing a process
Killing your programs is important because it relieves the workload on the CPU, therefore making data process faster for every user. Here is how to kill a process:
kill -9 PIDwhere
PIDis replaced with the appropriate PID, such as 2233 from above
If this does not work, try one the following
kill -9 -1
pkill -U username
Running a process in the background
ctrl-c is typically used to terminate a process. You would usually use this when a program crashes or when you are executing a program with infinite loops.
ctrl-z is used for running a program in the background. This will not terminate your process.
