To the idiots who thought it would be cute to use the Sylverant DNS resolver to launch DNS-related attacks, you really are not amusing. Thanks to you idiots, the DNS server I host is now locked to only provide the addresses for PSO-related hostnames. I’m also reconsidering whether I should host said DNS or not at this point, since it is obviously more trouble than it is worth. Not that I expect said idiots to ever read this post or anything else anyway.

To those who aren’t amongst the idiots, I guess this needs a bit of explaining… One of the options for connecting to Sylverant with certain versions of PSO for the Dreamcast (Network Trial Edition, USv1, EUv1, EUv2) and all versions of PSO for Gamecube was to use the Sylverant server as your DNS in your network configuration. This works because I host a DNS server that provides the IP addresses for certain PSO-related hostnames that the game uses to try to connect to a server. All of these addresses resolve to the same IP address as the Sylverant server itself. For convenience, the DNS server could also be used for general day-to-day use and with other online games, as it would recursively look up any hostnames it did not know about, and return the correct IP address for said servers by way of (primarily) Google’s Public DNS server. However, someone recently decided it would be a good idea to use this service that I provide (the DNS server) to launch a DNS query amplification attack (see here for more info on what that is). Thus I have had to stop allowing recursive lookups to prevent someone from performing such an attack. What that means is that the Sylverant DNS is now not usable for general day-to-day lookups (not that I expect many people were using their Dreamcasts for web browsing), nor can you use it in your network configuration for playing games like Quake 3 Arena on the Dreamcast any more (which was probably more commonly done).

I highly suggest that anyone playing PSO on the Dreamcast that does not already use the Sylverant PSO Patcher disc consider doing so in the near future. I may end up having to discontinue the DNS service if people continue to abuse it, so I’d like it if everyone was prepared for that possibility.

Now, from out in left field, a release…

Tonight, I have released version 2.0 of the Sylverant PSO Patcher. This version is almost a complete rewrite from the old version, fixes various bugs, and adds a few new features. Here’s a brief overview of what’s new:

• Added support for patching the hostname in and booting the PSO Network Trial Edition.
• Added support for patching in the music for the Palace and Spaceship stages into the main bgm table. This way, quests that use these stages in non-battle mode (Prospective Horizons on Altimira) can use the correct background music. This patch is optional. When you see the note about pressing Start for all patches or A for not patching the music, this is what is being referred to.
• Fixed booting of many import games that would not boot with the older version. This version still won’t boot Windows CE-based games, but it hopefully will work with just about any other game you throw at it, if you choose to use it as an import boot disc.
• Finally, and most importantly, this release fixes the issues with battle mode timing out immediately on all Dreamcast versions when using the patcher. No, there was never any bugs in the server with regard to this, which is why it worked for people that used PALv2 and didn’t use the patcher at all.

Due to that last fixed issue, it is recommended that all users update to the new patcher if they ever intend to play in Battle mode.

You can find the downloads on the Downloads page on the Google Code project. As with previous versions, there are downloads for the source code, plain files, and a self-booting CDI image (the CDI image was built by Aleron Ives and should be in the data/data format).

Well, as you might have noticed from the Twitter feed (as well as from other places), I’ve been on a bit of a hiatus the past month and a half or so. This was due to many different situations, and was planned in advance of the drama that unfolded over the server rules (sorry to disappoint anyone who thought that the drama there scared me away or something).

Anyway, I’m still pretty much on hiatus from Sylverant, but I did decide to use a bit of my free time the past few days to work on a few things. So, I figured a status update is in order (especially since the last one was back in April). So, without further ado, here’s what’s changed since the last “monthly” update:

• Warning cleanup in the code.
• Added code for parsing the ItemPT.afs and ItemPT.gsl files for PSOv2 and the later versions (respectively). Thanks to Lee for lots of information about the format of these files!
• Fixed a few issues that could cause segfaults in the server code.
• Don’t show Blue Burst games to Gamecube clients.
• Added code for parsing the map data from PSOv2 (in addition to the Blue Burst parsing that was already in the code).
• When a client leaves a team, send them back to the lobby they came from, as long as its not full.
• Added code for parsing the ItemPMT.prs files from PSOv2 (later versions are not supported currently). Thanks to Lee for some valuable information on the subject!
• Fixed a potential crash for PSOPC clients when searching for someone by guildcard or choice search when they are in a team that has a name that is of max length.
• Made the results for guild card searches have all the same information they did on Sega’s server.
• Fixed an issue with /minlvl and /maxlvl where they were off by one.
• Added code to the random number generation stuff to support multiple streams of random numbers (one per thread).
• Added a –check-config option to ship_server to make it so you can check the validity of a configuration file without actually starting the ship server.
• Added in parsing for the ItemRT.afs file from PSOv2 (once again, later versions aren’t supported right now, although this shouldn’t be much of an issue).
• Fixed a few minor issues in the map parsing code for v2 and bb.
• Track when clients hit a monster on v2.
• Prevent a potential segfault if map enemy data is not loaded for a team.
• Added support for full server-side drops on PSOv1, PSOv2, and PSOPC (and partial support for the other versions).
• Added the /sdrops command to enable server-side drops.

Most of these are fairly boring updates, except the last two. These probably need a bit of explanation, which will come more fully later on. For a brief explanation, continue on (with the continue reading link, or if you’re already on the full story by reading below).

Due to various situations that have arisen, the administrators of the Three Ships of the Sylverant system have decided on a set of global rules across all Ships. Please read the rules at the forums. Your continued use of the Sylverant PSO Server indicates your acceptance of these rules.

I’ll post them on this site as well at some point, but its rather late for me right now to do it. 😉
