>Environment:
FreeBSD 6.1-STABLE
>Description:
Whenever using SSH from an external network going to the FreeBSD box it locks up the server (dropping the interface?). After around 5-10 mins the server comes back up. Cannot remote access the machine through SSH although I can on my local network. Tried using putty and securecrt with the same results.
>How-To-Repeat:
Run standard version of sshd that comes with FreeBSD 6.1-STABLE.
Try and SSH in with putty or SecureCRT.
>Fix:
Don't know?
