Renewal Kerberos TGT in console SSH sessions

<html> Preliminary Remark: Kerberos Tickets can only be renewed for a timespan of 1 week. <br/>Then, you have to acquire a completely new login on behalf of your password. </html>

Login, open a screen session and execute the following command:

/usr/local/bin/krb5ticketrenew.sh &>/dev/null &

This procedure allows processes launched within a screen/tmux session on a remote host to survive repeated logins/logouts.
This recipe works for tasks running up to at most one week on the remote host.
