I am using inspircd 2.0.18 and when a user connect from this ISP (axtel.net) inspircd return the following error:

Error handling S2S command :326 UID 326BAXBFL 1429109071 gest688114 148-240-xxx-xx .ftth.dynamic.axtel.net chat-e91.nhu.8ffsj4.IP fl_cgs 148.240.xxx.xxx 1429109076 +x :realname

Protocol specification:

:<sid of new users server> UID <uid> <timestamp> <nick> <hostname> <displayed-hostname> <ident> <ip> <signon time> +<modes {mode params}> :<gecos>

User connection:

:326 UID 326BAXBFL 1429109071 gest688114 148-240-xxx-xx .ftth.dynamic.axtel.net chat-e91.nhu.8ffsj4.IP fl_cgs 148.240.xxx.xxx 1429109076 +x :realname

Visual comparation

inpircd-uid

You can see a white space between "148-240-xxx-xx" ".ftth.dynamic.axtel.net"

Why the hostname has white space? Is it possible inspircd bug? When this error occurred the two servers had a netsplit.

Thanks by advance.

Also if I do host command for this ip, you can see a "\032" character (whitespace character).

> host 148.240.xxx.xxx
> xxx.xxx.240.148.in-addr.arpa domain name pointer 148-240-xxx-xxx\032.ftth.dynamic.axtel.net.

it's not an inspircd error:
http://148.240.67.96.ipaddress.com/

it's really a whitespace. Who is that crazy?

We should catch this ISP error to prevent inspircd failures.

I would say it should use IP instead of hostname if there is a whitespace in it. Yes.

Yes I'm sure someone in the team will work on it soon.
We are discussing it in IRC now.

If someone have the same problem, set nouserdns="yes" until the error is corrected by the inspircd team
