Thanks!

I have created new Debian packages (Debian Buster, AMD64 only) based on
these 3 patches - available at
<https://itp.tugraz.at/Comp/debian/dists/buster/test/binary-amd64/>

A quick glance shows that my DB and file servers do work.

BUT: after restarting a client file access is not possible any more: "vos exa
.." works, but "ls /afs/itp.tugraz.at/" times out.

| root@faepop78 ~ # ls /afs/itp.tugraz.at/
| /bin/ls: cannot open directory '/afs/itp.tugraz.at/': Connection timed out

Best regards,
Andreas
