After setting up Wave in a Box on my Debian server, I started noticing strange things happening: I could no longer use sftp to transfer files, and even worse, I couldn't run any sudo commands! Thankfully, I could still
su to root. When I checked
/etc/sudoers, I found that it had been completely reset, with only the root user having sudoer permission.
I don't think my server was hacked, since I'm running denyhosts to shut out any attempts. Any idea what could have caused
/etc/ssh/sshd_config to reset themselves?
