pam_radius_auth delay

[Steve Phillips]

Ahh, wait - bad form replying to myself I know, but realise what you just mentioned was the host generating the query.

I'll look into this and ensure there is a PTR entry, but I'm pretty sure there was.

Of note though, surely the system would just use the 'hostname' to populate this rather than trying to do a PTR lookup?

    Hey Matthew,
    
    The delay happens if I use an IP address or a FQDN, and whether the FQDN is in the DNS system (of which there are two servers on the same subnet/switch) or if it is in my /etc/hosts file. This was one my original thoughts as well as generally delays like this are due to some form of timeout - but there doesn’t seem to be anything in the logs indicating a timeout.

        there is a call to add a RADIUS attribute with details of the
        remote host the user is connecting from, I would suspect that
        there is a missing reverse DNS entry for it.
