Nagios Support Forum

Hi Team,

I'm deploying the latest version of nagiosxi on fresh RHEL 8 server and installation got failed at 'http://www.cpan.org/authors/01mailrc.txt.gz' with error Connecting to http://www.cpan.org (http://www.cpan.org)|199.232.254.132|:80... connected.
HTTP request sent, awaiting response... Read error (Connection reset by peer) in headers.
Retrying.

I have tried all possible ways with wget parameters but did not work. Please suggest.

Hi Kunalv89,

There could be a couple of reasons that the download from cpan was reset. It may have been a cpan server issue or more likely an IDS/IPS system or firewall blocked the connection. The best thing to do is give it another try and if it resets again try pulling the file down manually using wget or curl:

To test with wget run the following on the command line as root:
or with curl
Thanks and Best Regards,

Hi Keith,

There is no progress, Still having the same issue.
From Firewall point of view, I'm able to downloads .gz files without any issue.

PFB the response of both the commands.

# wget http://www.cpan.org/authors/01mailrc.txt.gz

Hi Kunalv89,

Unfortunately this is something you're going to have to troubleshoot with your network/security/sysadmin teams. As you can see from the output of the wget and curl commands you executed something is resetting the network connection; without more information my guess would be an IDS/IPS system but your security/network/sysadmin teams should be able to help you to resolve the problem. Once you are able resolve the issue, and the wget and curl commands are succeeding, you should be able to restart the install and proceed normally.

Thanks and Best Regards,
Keith
