The service “sshd” appears to be down

Nizzo
Hi, Two questions: 1; Since yesterday I've been getting these notifications about the sshd service being down when it is not. Jun 18 20:35:36 web sshd[9282]: error: Bind to port XXXX on :: failed: Address already in use. Jun 18 20:35:36 web sshd[9282]: error: Bind to port XXXX on 0.0.0.0 failed: Address already in use. I changed the SSH port last year and its been working just fine till last night for some reason. I tried restarting the sshd service from WHM and through SSH with no luck, i always get the same error. 2; The server is very outdated. its running on:
  • CENTOS 7.3 x86_64 standard " web
  • WHM 60.0 (build 45)
Is it possible to upgrade directly to Version 78.0.30 ? Thank you.

    I guess the experts will tell you as a matter of urgency to update to the latest version. However, don't let me sway you in any way, I'm not an expert. Have you tried moving SSH to another port.

    Yes, i am planning to upgrade over the weekend. I just need a confirmation if it is possible to upgrade directly from version 60 to version 78

    Hopefully, the techs will be along shortly to confirm. I missed a few updates recently and upgraded from 76 to 80 last week. I'm pretty sure I saw it going through the steps to update to 78 before moving on to 80. It took a long time though, maybe 90 minutes from start to finish. If it does go through revisions sequentially, then expect it to take an age.

    Time is not an issue.. i just need to make sure it is done correctly and without breaking things up. So your saying is the upgrade it self went through 76 to 78 to 80 on its own? or did you have to manually go up each version? Out of curiosity, what are the specs on your server that it took 90 minutes to upgrade?

    What do you get when you run the following: ps faux |grep sshd
    Then if you subsequently perform a hard restart on the service: /scripts/restartsrv_sshd --restart --hard
    Do you continue to get the same error? You really should update as well, running on v60 of cPanel/WHM more than likely makes you vulnerable to the highly dangerous Exim CVE Exim CVE-2019-10149, how to protect yourself | cPanel Blog

    You set the target version - so if you set in WHM>>Server Configuration>>Update Preferences that you want to be on RELEASE it will iterate through the versions on its own from v60 to v80.0.18

    I am going to Update, i just wanted to make sure that i can upgrade from v60 to the latest without breaking anything. Any precaution i can take before attempting the upgrade?

    One more question, will there be any downtime when the long upgrade is in process?

    Hi @Nizzo I think the real issue here is the custom port you've set for SSH. It sounds like something else is already listening on that port. I'd suggest using an unused port between 1024 and 32,767 As far as the upgrade, I can't say for certain that you won't experience downtime but you shouldn't, it really depends on if there are issues or not, if you would like you can open a ticket using the link in my signature and we'd be more than happy to assist.

    @cPanelLauren Thank you. Something is weird happening in the server, that is for sure. I changed the SSH port to a different port and it restarted fine this time and no more notifications, but at the same time i can still SSH with the old port? also disabling root login in SSH does not take effect either. I think i will do a fresh install of WHM/OS.. Now i cant decide if i should upgrade WHM and then reinstall or just reinstall from scratch.

    You might save yourself some time if you reinstall from scratch if you do choose that route. Could it also be that you've left 22 in the config for SSH or not restarted SSH?
