Install DxSpider on Raspberry Pi

Revision: 1.01 – 12/11/2018

Here you find my installations guide how to install dxspider on raspberry Pi. Also you can find more information here If you need help please contact with me.

Furthermore if you don’t want make manual installation you can used my script for the installation and configuration Dxspider.

1. Fisrt change user from pi to root

$ sudo su -l

2. Create user sysop and setup password

# adduser -m sysop 

# passwd sysop

3. Install perl libraries

# apt-get update 

# apt-get install libtimedate-perl libnet-telnet-perl libcurses-perl libdigest-sha-perl libdata-dumper-simple-perl

4. Now download and  unpack the DX Spider distribution, set symbolic links and group permissions. Copy the tarball to /home/sysop and do the following.

# cd ~sysop 

# wget 

# tar xvfz CVSlatest.tgz 

# ln -s ~sysop/spider /spider 

# groupadd -g 251 spider

If you do not have the command ‘groupadd’ available to you, simply add a line in /etc/group by hand.

# vi /etc/group

You also need to add some others to the group, including your own callsign (this will be used as an alias) and root. The finished line in /etc/group should look something like this:
