Encrypted Hostnames

Hi,

I've been looking for alternatives to TitanIRCd, I've tried LiquidIRCd but can't get it to compile(well, link) on FreeBSD (even after manually patching resolv.h I still get the undefined reference to `__res_state' from res.o)...

I was wondering if anyone could recommend an IRCd which has SSL, MD5 encryption(hashing) of hostnames and is quite stable? Smile

Thanks.

Kotka.

Does Unreal let you fully encrypt(hash) hostnames with MD5 now?

we use 3.2-beta17b on another network and it only support "VWorld" masking :S

thanks,

Kotka.

UnrealIRCd uses CRC32 and a specific algorithm to hash part of the hostname. It does not obfuscate the entire thing; just a piece to make it unresolvable. Personally, I think it's more useful than encrypting the entire thing. MD5 is a little slower to use, I believe, since it's 128-bits and CRC is only 32-bits (I think?). Since we're hashing and not trying to protect particularly sensitive permanent information (By the time a hash would be cracked it'd probably no longer be useful). UnrealIRCd uses three numbers supplied by the configuration file (set by the admin) to keep all hostmasking uniform across the network but unique to each, to prevent reverse engineering. All in all, I'd recommend UnrealIRCd, not only for its hostmasking, but for its all around usefulness as a stable IRCd.

hehe Thanks for both you're replies/suggestions.

I've never been extremely keen on Unreal (even though I have to use it for another network).
I'm really looking for something very small, but still stable... Doesn't really need to be feature rich except having fully hashed hostnames, and SSL hehe :>

Thanks again,

Then check out NoLimit at: http://sourceforge.net/projects/nolimit
It has full encryption of the hostmask and SSL for opers and users.

Have you considered applying the res fix patch?

hewwo Ashen Wink

Yeah, though the IRCd I was using was modified, so I had to patch res myself.

Sadly, it made no difference... I have recently learned that on most systems, compiling res isn't required and NoLimit allows you to specify if you want it compiled in or not :>
