Hi. It’s not related to Quagga. It’s a bug in all mighty systemd specifically in nsswitch, related to hostname resolving when many routes are present and might be exploitable too, but noone cares. Bug reports were submitted 4 months ago to CentOS and RHEL bug trackers. In order to get around it either disable DNS resolution in sshd, but then other programs like ping will still crash, so far better workaround it by removing myhostname from config directive hosts, like so:
hosts: files dns But please note, that upgrading software like systemd will put the myhostname back without informing you and it will start to crash again. So also do the sshd_config. You’re welcome.
