Fixing slow or broken NFS mounting issues

Make sure a firewall rule isn’t blocking NFS. If NFS is running on the server and clients _can_ mount, but it’s just really slow, then things get a little hairly. You can’t just look for a problem on a client or a fix a misconfigured server. You’ll have to look at the whole ball of wax… If MTU mismatch doesn’t seem to be a problem, try going the other way and increasing the MTU size. Use the traceroute command to look for unexpected routing hops or delays.

Create SSL certs and enable https with Lighttpd

Now edit the lighttpd.conf configuration file to enable ssl. Use the public facing interface’s IP address instead of mine, unless yours happens to be 192.168.1.2 too! And nmap or netstat will let you know it’s listening on port 443
