Alternatives to ClearOS

Since ClearOS has been abandoned, I’m planning to move my home server to a different OS. I’d like to know what you think of available alternatives and whether there’s a way to install the new OS without wiping the hard drives.

I executed: # xfs_repair -n /dev/dm-0 and got the following:

Can't Boot: XFS Error

My home ClearOS server stopped working. The console shows the following message:



I tried to boot the a rescue kernel, but that game me the same error as the above


Any suggestion on how to resolve this issue?

Thank you

I ended up deleting /etc/ssh config files and reinstalling ssd. Everything seems to be working now.

I changed the default SSH port and tried to login again. The SSH wouldn't connect without "-oKexAlgorithms=+diffie-hellman-group1-sha1", but when I use this parameter, the SSH refuses to log me in! I can login from the server console directly (keyboard and monitor connected to the server), but not remotely over SSH!

Suspicious Message from SSH Server!

I just got a strange message when I was trying to login! I launched the macOS Terminal app and typed:

I didn't get the usual password prompt, instead I got this message:

Unable to negotiate with 192.168.1.2 port 22: no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1

I searched the Internet and found that passing the argument "-oKexAlgorithms=+diffie-hellman-group1-sha1" to the ssh command would pass this message. But when I tried to login with the said argument, I got this message:

I have not done anything to the server since I last successfully logged to it yesterday. And the auto-update is turned off. The client also (the macOS system) hasn't been changed as well. Is there something fishy going on in my server?

Most rotation is controlled by /etc/logrotate.conf and all the configlets in /etc/logrotate.d/. If you have files in /var/log/samba.old then rotation is taking place. That is how they got there in the first place.

Great news Nick.

Should testers report back their findings here in this thread or somewhere else?

Logs Rotation?

/var/log folder in my server is more than 65GB in size! The largest folder in there is ./samba/old. It's clear that no log rotation is taking place. Any idea how clearOS logrotate works and where to find its config file?

Thank you

AFAIK the ClearOS repo packages are fine. python2-cffi python2-ipaddress and python2-pyOpenSSL are not needed and python2-cryptography-1.7.2-2.el7 is fine. I have a feeling you have repo problems.

python2-cffi and python2-ipaddress are required for the newer version of python2-pyOpenSSL. python2-pyOpenSSL is a request for app-lets-encrypt.
