Problem connecting to KVM with Virt-Manager

Recently I have had some issues with connecting from my laptop running Linux OS (Fedora 30, Xubuntu 19.04) from virt-manager to server running KVM. Virt-Manager keeps asking me for root password, which was very annoying.

The solution was simple – first I had to create ssh keys which then I needed to send to my CentOS(7) server running KVM

and check to make sure that only the key(s) you wanted were added.

After that I was able to use Virt-Manager without any asking for password.

Debian GNU/Linux 5.0 Lenny

On February 14 the new Debian version – codename “Lenny” show up. I decided to upgrade my Debian server based on Etch.

First I made backup of /etc/apt/sources.list and next i manually changed lines:

before change:

deb http://ftp.pl.debian.org/debian etch main

deb-src http://ftp.pl.debian.org/debian etch main

deb http://security.debian.org/ etch/updates main contrib

deb-src http://security.debian.org/ etch/updates main contrib

after change:

deb http://ftp.pl.debian.org/debian lenny main
deb-src http://ftp.pl.debian.org/debian lenny main
deb http://security.debian.org/ lenny/updates main contrib
deb-src http://security.debian.org/ lenny/updates main contrib

The last thing was to update apt settings

# apt-get dist-upgrade

and the upgrade process begins 🙂

How-to: Mounting Novell shares under Debian

Earlier i have describe how to get into Novell shares. Now I want to show how to get this under system boot.

As we know the /etc/fstab file contains information about our partition and mount points,

[file system] [mount point] [type] [options] [dump] [pass]

Now, we have to add information into /etc/fstab about Novell shares like this:

server/user mount_point ncpfs options 0 0

NOVELL/JOE /media/novell ncpfs rw,user,passwdfile=/etc/ncppass 0 0

In /etc directory we have to create a file wich will contain information about our Novell login and password. The information should look like

SERVER/USER:password

i.e.

NOVELL/JOE:joe1975

The last thing to do is to restart your server and enjoy Novell shares in Debian 🙂

How-to: Debian and Novell

I decided that I will describe things that I do in my work.

Lately I have got to get into Novell shares to make backups of all user document etc. I decided to use Debian.

In general I have to get installed two packages from Debian repisitory:

# apt-get install ipx ncpfs

After that I have to add to the network interface capablity to connect via IPX

# ipx_interface add -p eth0 EtherII

using command

# ifconfig eth0

we can check if option IPX/Ethernet show up. Next, by using slist, we can list available Novell servers in our network.

Next thing to do is create a directory where we can mount our Novell server shares. We can do it either in /mnt or /media.

# mkdir /media/novell

Last thing to do is mount Novell share like this:

# ncpmount -S server_name -U user_name -P password path_to_dir

After that we can finally use Novell shares under Debian 🙂
