Past Active login sessions in AEM Dispatcher

Question

Hello All,Good Day!I was trying to login into the AEM Dispatcher instance from 2 Git-bash windows (We use to clear the cache from one window and check the status of the cache clearance from other window). But I was not able to login via 2 windows. I was getting below mentioned error.Error :- "Too many logins for '{username}'."Upon checking the logged in users via 'w' command I found following information.{username}@3165742*****ryd**onc**-p****1-dispatcher1u***1-*********14:~ w12:39:24 up 38 days, 22:50, 4 users, load average: 0.41, 0.69, 0.81USER TTY FROM LOGIN@ IDLE JCPU PCPU WHATaru***g pts/1 103.43.112.97 19Feb25 0.00s 0.00s 0.88s sudo su -n***h.* pts/3 10.12.54.15 12:25 1.00s 0.02s 0.01s wn***h.* pts/4 10.12.54.15 Tue07 0.00s 0.00s 0.00s sudo /bin/rm -rf /mnt/var/www/html/bin /mnt/var/www/html/content /mnt/var/www/html/etc.clientlibs /mnt/var/www/htmln***h.* pts/5 10.12.54.15 Tue07 0.00s 0.00s 0.01s sudo /bin/systemctl status httpdIt seems some past login sessions are somehow still open. how to get close the past active sessions.

Hi @nitesh-chavan ,The error message "Too many logins for '{username}'" suggests that multiple past sessions might still be active, preventing you from logging in again. To resolve this, you can manually terminate these lingering sessions.Steps to Close Active Sessions:1. Check Active SessionsRun the following command to list active sessions: w or who (This will display all logged-in users and their session details)2. Kill a Specific SessionIf you identify a session (e.g., pts/1) that needs to be closed, you can terminate it using:sudo pkill -t pts/1 (This will close the session for pts/1)3. Kill All Sessions for a UserIf you want to log out a specific user entirely, use: sudo pkill -u {username} (Replace {username} with the actual username to terminate all active sessions for that user)4. Manually Kill Processes (If Needed)If pkill does not work, you can manually find and terminate processes associated with a session:Find the process ID (PID) for a session (e.g., pts/4): ps -t pts/4Example Output:PID TTY          TIME CMD12345 pts/4    00:00:00 bashKill the process forcefully: kill -9 12345Preventing This Issue in the FutureAlways exit sessions properly using exit or logout.Set up automatic session timeout by editing /etc/ssh/sshd_config:ClientAliveInterval 300ClientAliveCountMax 0Then restart SSH: sudo systemctl restart sshdRegards,Amit

You can terminate a specific session using the pkill command followed by the session ID. For example, if you want to close the session with ID pts/1:

sudo pkill -t pts/1

This command will terminate all processes associated with the terminal pts/1.

If you want to close all sessions for a specific user, you can use the following command:

sudo pkill -u username

Replace username with the actual username.

If pkill is not available you can use kill command:

#Use the ps command to find the PID associated with the TTY
ps -t pts/4

Example output:
  PID TTY          TIME CMD
12345 pts/4    00:00:00 bash

#Use the kill command to terminate the process
kill -9 12345
