I've released a new directory server on my website: SubSpace Directory Server

It's similar to Catid's directory server but it's written using modern, cross-platform code and has a few features that go beyond what we've seen so far. This is the same directory server that powers subdir.org and subdir.net.

As of this post, I've only made the Windows binary available but I'll put up a Linux binary in the next few days.

The source code is available as well although for the moment it will only compile with MinGW and MSVC++ on Windows. Again, I'll make the Linux version available shortly.

The code is best compiled with scons http://www.scons.org and the provided SConscript file. If you want to compile with MinGW, use: scons mingw=1 on the command line.

I haven't taken a look yet; but does it do everything catid's does? Will it mirror other directory servers? Does it do anything w/ the "password" field?
I'm curious why you haven't integrated it into the biller directly.

Sounds great, I'll wait till Linux/UNIX binary.

CypherJF: I'll be honest, I don't know all about Catid's server. I know that the major distinguishing feature was that it was 'distributed' (it mirrored other directory servers) and that's what I was referring to when I said "similar to Catid's". Currently my directory server uses the password field to prevent zone redirection - if you register your zone with a password, nobody else can update that zone's information unless they also use the same (name, password) combination. The zone passwords are reclaimed after a configurable amount of inactivity.

I haven't integrated the directory server into the biller primarily because I don't think there's a need to. Sure, it's nice that a subgame/asss instance doesn't have to repeatedly ping a directory server, especially since it already pings the biller every so often. On the other hand, the biller and directory servers provide two entirely different services. Their physical separation is really a consequence of their conceptual separation. Their code evolves at different rates so their (re)deployment will also happen at different times so downtime on one for maintenance/upgrades won't affect the other. Process separation is also really nice to have - if the dir server goes down, I don't want to the the biller with it. I can distribute the code for one and not the other - that's pretty good in this scenario. I think in the end, there just aren't enough good reasons to merge them and there seem to be plenty of good reasons not to.

Kingsize: I've uploaded the Linux source and binary. If you have trouble running the precompiled binary (i.e. library issues), you can compile from source. Just go into the subspace/dirserver directory and run scons.

Installed Fedora Core 10, and everything went just fine untill:

SUMMARY
- ZoneRefreshSeconds causes the program to silently crash after the number of seconds you set it to when you launch the program (ie. if set to 120 seconds, 120 seconds after launch the program will end).

- [Unknown, see test at bottom] ZoneRefreshSeconds will only cause the program to crash if someone tries to download within the first/initial cycle. If the program is launched and it is left alone, and no IP or address is given out and nobody requests a listing from it, the program will just sit. Any requests during the second or later cycles will not cause the program to end.

- [Unknown, see test at bottom] ZoneRefreshSeconds will cause the program to crash if its value is less than or equals StatisticsWriteSeconds.

- Logs do not give any reason why the program ends after the first/initial cycle of ZoneRefreshSeconds has been met

- If stats folder does not exist, the program will not automatically create it and will complain about it in logs. No precreated files have to exist in the stats folder though, as the program will automatically create those files as necessary.

Other Notes: I think it has something to do with or centering around ZoneRefreshSeconds. There are so many variables involved here that it kind of gets tricky when trying to figure out how to proceed after unexpected results. Value of -1 doesn't cause it to complain at startup, but I do not know what the effects of -1 are. Maybe it is a way to disable UpstreamServers?

EUREKA!
By setting ZoneRefreshSeconds to -1, which apparently effectively disables UpstreamServers, the directory server operates normally, responsively, and like it should (except with UpstreamServers disabled). I will be running the directory server at ss0.hlrse.net for a few hours to see if it crashes.

EDIT :: Day later and it is still running! The problem centers around ZoneRefreshSeconds and UpstreamServers.

Straight out of the box it looks like it runs normally, but I can't get any zone listings from it. I'm trying this out on my laptop and a Windows Server 2003 machine.

When I specify a port other than 4990, I can get a listing from my laptop, but find it difficult to get one from the other machine. I also blanked out the value for UpstreamServers so that the directory server would be standalone.

I want to think that when it saves or writes zones to memory, it crashes silently. Either that or something else...

Here is a log from my laptop:

Bug smashed!

Problem: DLL hell
Solution: Install Microsoft Visual Studio 2005 SP1 Runtime Library (vcredist2005SP1_x86.exe - 2,660 KB)

Can't install it for whatever reason? Download the attachment msvcrt.zip and extract msvcrt.dll into the same folder as your dirserver.exe.

Still have problems? Download the second attachment and pop the archived msvc*80.dll files into the same folder as your dirserver.exe.

scp might help, but it uses SSH instead of FTP.

scp -r directory_to_copy username@host:/path/to/destination_directory
