Summary0004952: Failure to display any /motd & /rules 2 hops away from local server
DescriptionFor quite some time and several unrealircd versions (including 3.*) it does not seem possible for a user to display locally any info about a remote server such as /motd /rules /botmotd. However /admin does work and opers can /rehash any remote hub.


Network layout:
/Links
hub2 hub1 :2
services hub0 :1
hub1 hub0 :1
hub0 hub0 :0

/Map
hub0
|-services
`-hub1
 `-hub2
Steps To Reproduceuser on hub0
/motd hub0 (and obtains)
/motd services (and obtains)
/motd hub1 (and obtains)
/motd hub2 (MOTD File is missing)

user on hub1
/motd hub0 (and obtains)
/motd services (and obtains)
/motd hub1 (and obtains)
/motd hub2 (and obtains)

user on hub2
/motd hub0 (MOTD File is missing)
/motd services (and obtains)
/motd hub1 (and obtains)
/motd hub2 (and obtains)

user on any hub can always obtain /admin from any other hub
oper on any hub can always obtain /opermotd from any hub

 Hmm. I cannot reproduce here:

:testlink2.test.net 006 Nick :`-maintest.test.net    (1)

Do you have any other MOTD-related configuration? Such as tld blocks and such.

Yes I do and all the motd's work well locally within each server as well as to the directly linked server. They only fail when requested 2 hops away.

Hmm. I see I forgot about this one. Is this still an issue?
Also noticed that none of the tld's match if you are non-ssl. Could be related.

The issue still remains with UnrealIRCd-4.0.18 (Fhin6OoEM3)

Only SSL/TLS is used.

The problem is never on the next connected hub but always 2 hops away. In order words, it fails to display locally the motd of the hub connected to the hub connected locally.

I tried both without any tld { } blocks and with the following tld { } block:
// tld test for motd problem:
tld {
        mask *@*;
        motd "testlink.tld.motd";
        rules "testlink.tld.rules";
};

I think the tld::options::ssl is the problem: the remote users are never detected as 'ssl'. I suppose that is a bug and it should look at the +z user mode.
Just out of curiosity, why the tld::options::ssl if all your clients are on SSL? Or did I misunderstand :)
