Debian GNU/Linux mounting Novell NetWare volumes

This is example of mounting Novell NetWare 5.1 partitions with Debian GNU/Linux (in this case - unstable with kernel 3.2.0).

First we need ncpfs package.

# apt-get install ncpfs

Then we need ncpfs module in kernel (it comes with debian kernel).

# modprobe ncpfs

Novell Context is support.gabrovo.hq
Username is niki
Server IP address is 10.1.42.24
Volume to mount is called - data

# ncpmount -o tcp -S 10.1.42.24 -A 10.1.42.24 -U niki.support.gabrovo.hq -V data /mnt/
Logging into 10.1.42.24 as NIKI.SUPPORT.GABROVO.HQ
Password:
# ls -la /mnt/
total 5

drwxr-xr-x 24 root root 4096 Mar  7 14:12 ..

# df -h

10.1.42.24/NIKI.SUPPORT.GABROVO.HQ                               137G 132G  4.9G  97% /mnt

Mount options and what they mean as follow:
-o tcp - use tcp (or -o udp)
-S 10.1.42.24 - server name/ip address.
-A 10.1.42.24 - which server to ask for name addresses.
-U niki.support.gabrovo.hq - niki is the user name and support.gabrovo.hq is context tree.
-V data - name of the volume to mount - "data".

If you did something wrong when mounting you can clear all your connections to novell with the following command:

# ncplogout -a

How to install djbdns in Debian Squeeze as deb package

Djbdns deb package is missing from latest Debian release (squeeze). There is a discussion regarding rapid dns cache poisoning attack which prevented djbdns package to be included in Debian squeeze release. There are two packages for djbdns in debian - djbdns which is original package of djbdns + 3 minor patches fixing some problems and dbndns which is debian fork of djbdns + ipv6 support patch. If you need ipv6 support in your dns install dbndns, if you don't need it i suggest you to install djbdns package.

Here is how can you install it on Debian squeeze as a deb package.

Add this line to /etc/apt/sources.list

deb-src http://ftp.bg.debian.org/debian/ sid main non-free contrib

You can choose another debian mirror if you like.

# apt-get update
# apt-get source djbdns

This will download source of the package and unpack it in your current directory. We need build-essential meta package installed so we can build some custom packages.

# apt-get install build-essential

Now all we need is to enter the directory of the unpacked djbdns package and run:

# dpkg-buildpackage -uc -rfakeroot

If there is no error the result of the above command will produce djbdns_1.05-8_i386.deb package which contains tinydns, dnscache, axfrdns ... etc. and dnscache-run_1.05-8_all.deb which contains run scripts for daemontools. All you need is to install them as follow:

# dpkg -i djbdns_1.05-8_i386.deb dnscache-run_1.05-8_all.deb 

Just to be sure that nothing goes wrong after upgrade we need to 'hold' these packages

# echo djbdns hold | dpkg --set-selections
# echo dnscache-run hold | dpkg --set-selections

Make sure to check this readme  /usr/share/doc/djbdns/README.Debian

Note: /service directory is moved under /etc/service to match debian configuration standarts.

That is all, now you have working djbdns (or dbndns) as a Debian package in squeeze
