I have installed FreeBSD and need to run regularly reverse shell to establish and keep alive SSH connection to the client (no public IP). When running the ssh -R script from the terminal, it works as expected, but when I run it as a cron command, the connection is established and disconnected right after that.
Here is auth.log from the server:
Jan 26 08:50:00 sshd[9696]: Accepted publickey for XXXX from XXX.XXX.XXX.XXX port XXXXX ssh2: RSA SHA256: xxxxxxxxx
Jan 26 08:50:00 sshd[9696]: pam_unix(sshd:session): session opened for user XXXX by (uid=0)
Jan 26 08:50:00 systemd: pam_unix(systemd-user:session): session opened for user XXXX by (uid=0)
Jan 26 08:50:01 systemd-logind[458]: New session 107 of user XXXX.
Jan 26 08:50:01 sshd[9794]: Received disconnect from XXX.XXX.XXX.XXX port XXXXX:11: disconnected by user
Jan 26 08:50:01 sshd[9794]: Disconnected from user XXXX XXX.XXX.XXX.XXX port XXXXX
Jan 26 08:50:01 sshd[9696]: pam_unix(sshd:session): session closed for user XXXX
Jan 26 08:50:01 systemd-logind[458]: Session 107 logged out. Waiting for processes to exit.
Jan 26 08:50:01 systemd-logind[458]: Removed session 107.
Do you have an idea, what causes this behavior and how to fix it?
Solved - see posts above. Thanks
