To answer your question:
In certain circumstances starting ssh-certd fails with fatal error "Could not open listener for the validation server". To resolve the issue, remove the existing listener socket file manually.
for example when ssh-certd process is unexpectedly or forcefully terminated, the validation server's listener socket file may not get removed automatically. Consequently attempts to (re)start ssh-certd will produce error message like:
# /etc/init.d/ssh-certd start Starting ssh-certd: ssh-certd: WARNING: Can not bind local address /var/run/ssh-certd-listener: Address already in use ssh-certd: FATAL: Could not open listener for the validation server
