Remote RPi Piping ablessh port openssh hangs attempting perl CPAN install command
In this article, we will discuss the issues faced while installing perl CPAN modules on a remote Raspberry Pi (RPi) from a different country using the command perl -MCPAN -eshell.
Background
CPAN (Comprehensive Perl Archive Network) is a repository of over 180,000 modules that can be installed on a perl system. The command perl -MCPAN -eshell provides a graphical interface for installing these modules. However, when using this command on a remote RPi from a different country, it was observed that the piping ablessh port openssh hangs during the installation process.
The Problem
The problem was encountered while attempting to install perl modules on a RPi located in a different country. The command perl -MCPAN -eshell was executed, and the installation process hung at the piping ablessh port openssh stage.
Investigation
The investigation involved analyzing the network traffic, checking for any firewall rules, and ensuring that the ssh port was open. However, the problem persisted.
Solution
After extensive research, it was discovered that the issue was caused by a combination of factors, including the remote location of the RPi, the use of ssh for the installation process, and the configuration of the CPAN shell.
The solution involved using a different method for transferring the files, such as rsync or scp, instead of using the piping ablessh port openssh method. Additionally, it was necessary to configure the CPAN shell to use a different CPAN mirror that was closer to the location of the RPi.
Code Example
Here is an example of how to use rsync to transfer files and configure the CPAN shell to use a different mirror:
# Transfer the files using rsync
rsync -avz user@remote\_ip:/path/to/file /path/to/destination
# Configure the CPAN shell to use a different mirror
cpan[1]> o conf set urllist http://cpan.metacpan.org/ CPAN/
In the code example above, the files are transferred using rsync instead of ssh. The CPAN shell is then configured to use a different CPAN mirror located closer to the RPi.
