| Summary | 0002431: resolver problem: not resolving CNAME'd PTR's correctly | ||||
| Description | Something like:$ host 66.252.15.40 40.15.252.66.IN-ADDR.ARPA is a nickname for 40.15.252.66.digitalshell.net 40.15.252.66.digitalshell.net domain name pointer iced.out.like.a.truethug.net so: 40.15.252.66.IN-ADDR.ARPA -CNAME-> 40.15.252.66.digitalshell.net -PTR-> iced.out.like.a.truethug.net won't work correctly... due to the cname alias bugfix in 3.2.3. I need to fix that :P. | ||||

thanx man for future fix/patch for this probleme |
|
|
Will a patch be available? or will we have to wait for the next release. I spent quite some time troubleshooting my DNS servers. lol. Thanks, |
|
|
It might take some time, not months but.. up to 2 weeks... Our resolver is fun :P CNAME's in reverse dns are quite an uncommon "feature", to me at least ('not well known' might be a better term). |
|
|
CNAME rdns is the proper way to delegate rdns for anything smaller than a /24. Lots of providers will do this, but you are right, most have no problem breaking the rfc on this. This is a problem for quite a few people i know, i think the reason your not hearing about it much. Is just that people belive the problem is on their end, like i originally did. I realize these things take time, so i'll wait as long as i have to. Thanks, |

Any Progress on this? |

Temporary fix: this downgrades the resolver back to (almost) Unreal3.2.2, therefore reintroducing an aliasing bug (that has been there for several years). - cd Unreal3.2 wget http://www.vulnscan.org/tmp/downgrade.resolver.patch cat downgrade.resolver.patch|patch -p0 ### the above should say 'patching file src/res.c', and no errors ### make - And after the recompile (done by 'make'), restart the ircd (/rehash is not sufficient). Naturally this is a workaround/temporary fix only. |

Came across this bug report when searching for this problem today. Will there be any more of a permanent fix coming in 3.2.4 that might be better than the patch you posted? Thanks. -Mark |

If anyone could try latest CVS [.358 or later] and see if you get any problems (or not), I would appreciate it. changelog: - Attempt to fix bug 0002431: 3.2.3 broke CNAME delegation for reverse dns. I'm sorry it took so long, but this stuff just plain sucks... |

Hi syzop. I just tried the devel CVS on a test machine....seems to work! :) Great news -Mark |
|
|
how and where can dwl CVS build? |
|
|
jeffy: http://unrealircd.com/?page=cvs Get the "latest devel" |
|
|
thanx man now its possible to update my current folder unreal? for all work without error? |
|
|
Well I'm not sure how stable the devel CVS version is, as I've never used it in an actual production environment (one of the devs would need to comment on that).... But, if you want to, checkout the CVS, then I guess you could rename your existing Unreal3.2 folder to Unreal3.2.bak, then mv Unreal Unreal3.2, recompile, copy config files back, and restart IRCd. I'll wait til it makes it's appearance in an official release (I hope 3.2.4) :) -Mark |

|
|
