Hello,
I have a suggestion for a client program/package in combination
with apt-cacher-ng
Consider following situation:
User U_A has a laptop which he uses at home and at university
He has a poor internet connection in both places.
So he set up apt-cacher-ng services in both places but they are on
different networks (he does not have permission to change the
network settings at university to make the IP addresses of the
apt-cacher-ng servers math)
Lets say at home the server HOST_1 is http://192.168.1.100:3142
At university: server: HOST_2: http://192.168.76.56:3142
He uses Ubuntu (so this should work for Debian in a similar way).
He makes a backup "/etc/apt/sources.list.bak" of
/etc/apt/sources.list
At university he sets up the cache repo as follows (after
overwriting the /etc/apt/sources.list with a copy of the backup
if it was changed to use the home apt-cacher-ng)
sed -i 's/de.archive.ubuntu.com/192.168.76.56:3142/g'
/etc/apt/sources.list
The same procedure at home.
The shown way is not very comfortable.
1. it is annoying having to remember IP addresses
2. sed command is error prone (consider typos, etc.)
3. copying around backup files is time consuming having to type
in all the paths
4. typing in sed command or searching it in bash history for
re-using is time consuming, too.
What I would like is to setup all cachers one use a program
(lets call it apt-cacher-switch for now)
apt-cacher-switch add <Host1_Name>
<http://<IP1>:<PORT1>>
apt-cacher-switch add <Host2_Name>
<http://<IP2>:<PORT2>>
Then at university:
apt-cacher-switch enable <Host1_Name>
At home:
apt-cacher-switch enable <Host2_Name>
In an environment where no cacher is on the network
apt-cacher-switch disable
The apt-cacher switch should manage creating and copying around
the required /etc/apt/sources.list files.
As I am not very talented in C/C++ programming under Linux, I am
asking the community to make it happen.
I would be very happy if this could be implemented and the
package be added to the official Debian and Ubuntu (and other
derivates') repositories.
Best regards
Chris
