SSH closed in 120 minutes when wget one file – CentOS

In CENTOS7, I use wget command to get one file. But ssh session will be closed in 120 minutes. In every 20 minutes, the following information appeared.

Your terminal (/dev/pts/0) has been idle for 63 min.
Press Enter key or you will be logged out any time after 56 min.

I modifed the parameter in /etc/ssh/sshd_config as following:

ClientAliveInterval      60
ClientAliveCountMax     5000000000000

But the problem does still exist.

    You can let wget run in the background with -b option. The ssh session can be closed but the ssh process runs on. source

    The above output is NOT standard sshd or any process of Linux OS.
    I guess you are using a Nokia deployed system.
    There is a private process /usr/sbin/KillIdleSessions to do such jobs as named.

    Its configration file is:
    /etc/security/kis.conf

    Normally, this process is scheduled in root crontab.

    You can use:

    /usr/sbin/KillIdleSessions -disable

    Reenable when done, or don’t. Autologout after 24 hours make sense. Autologout every few minutes does not, especially as it isn’t very good at detecting activity.
