Hiya, we are currently playing (and bug testing) the development versions hosted on a dedicated Linux server and are experiencing issues with vanishing craft.
These seem to occur when only one of us is playing and then logs off and then the other player logs on at a later time leaving a period where the server has no active players.
It is as if there is no forced sync of craft when a player disconnects to save the state when the other player connects which seems to be causing loss of craft.
Our gameplay is set to the following:
warpMode: 1 (MCW_VOTE)
gameMode: 1 (CAREER)
loglevel,0 (DEBUG)
If you require more information or need us to test things out, we will be more than happy to participate.

There seems to be some random bugs related to the Kerbals contained in pods.
Some examples -

-In a 3-person capsule, I send one of the Kerbals out to make room for my friend's EVA Kerbal. When he tries to get it, it still shows up as "full".

-I go back to the space center and my friend takes control of my craft. He flies around for a bit, and then when I come back, there is a Kerbal missing from my craft...

Just some mysterious stuff.

I've seen this a while ago, happens to me every time I try to force close my KSP while connected to a DMP server.

Just connect to the server, and press Alt+F4 when something like syncing is happening - your game should crash.

1. Open chat
2. Click the chat field
3. Click the "chat" button on the Status window
4. Freak out that you can't control your rocket

Should just involve a single heartbeat to the client with the same name before rejecting them.

While I've already discussed this at great length on the Single Kerbal Mode issue on KMP, I did want to mention it here as well:

It should be possible to have specific Kerbal(s) bound to an account. This would mean that only account(s) defined as an owner of a given Kerbal should be able to EVA or control them.

Here is some examples of functionality that I would like to see, ordered in terms of expected difficulty/when they might be possible:

• The server stores Kerbal names and user ownership
• The server admin can rename a kerbal via the database, which is reflected on clients after resync.
• The Client allows the owner of a Kerbal to change their name. Initially this could be done with a simple /rename command while on EVA for example. Much later this could be integrated in some sort of Mission/Inspector UI.
• If a vessel's current pilot does not have ownership of a given Kerbal, that kerbal can not be EVA'd. Same for Kerbals in Pods/Lab/etc.

I think this could lead to a very intuitive permissions system, where a kerbal is assigned to another player, which would allow them to take over the controls of the vessel. similarly a player that is EVA'd and enters a vessel would also be able to request command of said vessel. If a player has none of their kerbals on a vessel, they can't take control of it, simple as that. For an even more hardcore mode, you can only spectate a ship if one of your kerbals is on board.

Currently it's unclear wether the user has a screenshot uploaded or not - This will make it clear :)

Linux can just run the game as a screen, but Windows requires an account to be logged in for any console programs to run in. .NET has wrapper classes to enable a program to run as a service, but this will have to be done in a Linux friendly way.

The in-game UI will move the window when the minimize button is clicked. Maximize works as expected.

May stop vessels randomly disappearing

We need two components for User-Definable Options:

Options File

An options text file should be added where various variables such as keybindings can be exposed. This should be high priority.

Options UI

You can add an 'options' button next to the disconnect button on the status window. This would make sense since you wouldn't need the options button to be accessible when the status window is minimized. This does not need to be as high priority if you can have the options text file.

After disconnect and reconnect, "You have been disconnected" stays on the screen.

Attempting to login with a ridiculously long name will, at least on mac OS, trigger a System.IO.PathTooLongException: http://pastebin.com/FjAMvw7g

However even using an unreasonably long name is currently possible:

• http://i.imgur.com/lga07j9.png
• http://i.imgur.com/GodUq1R.png

I think it would be more reasonable if you capped the length of the player's name to something like 16 or 20 characters, and hardcoded the server browser Player Name field to only hold that many characters (so even pasting in a long name should just be cut off).

I think its a good idea. Feel free to close this if you disagree. :P

To reproduce:

1. Player 1 connects to server, creates spacecraft and leaves the default name, launches spacecraft to orbit, then renames craft
2. Player 2 connects to server, checks the tracking station and sees the old default name

For me under windows. Reopening doesn't seem to matter. Upon further investigation clearing the vessel cache seems to clear it.... which is odd.

• Two players sync'd
• One player launches while other player watches tracking station
• Couldn't see the craft in tracking station until it hit about 70-80km above Kerbin
• Neither player used time warp during the launch

KMPModClient is currently sitting here:
https://github.com/godarklight/KMPModClient

Integrating it into DMP gives us the ability to ask the user questions and work through what they need in order to fix their GameData directory.

Mine is 108 megs. That's 1700 txt files, haha. Either have it save two or three servers, clear up old files, or clear upon connection to a new server. MAY also have a side effect of greying out the tracking center.

[14:07] [DMPUser_788] hi, love your server software but we're getting an error... disconnected cannot access a disposed object... also occasionally getting an error that says cannot connect to a non dmp server... any ideas? everything was working last night
<><><><><>
[14:16] [DMPUser_051] hi, we set up this server / client system the other day, and everything worked fine..then we slowly added mods that we had been using on the KMP system (5 adds so far) and it seems that 2 of us can connect but then it starts giving errors for others who try any idea? the errors are: Connection fail: error handling SPLIT_MESSAGE Message and today's : Disconnecting from a non DMP server (that is running DMP)

A much loved feature from KLF/KMP missing from DMP...

Very obvious with rovers. Seems to be worse with lag (obviously).

Edit: Still getting random explosions, disassembly and duplication with nearby rovers, as well. Figured I might as well give a few more details. hah.

Currently, The sync will try to apply every single future update.

We only want to apply the last update for each vessel.

This will probably work minecraft-style ;)

Two nights ago, my and my friend docked a bunch of stuff together in a nice space station around the Mun.

Tonight we logged on and the station was totally gone - no idea what happened. No debris from the station - so it didn't explode (I think). Also, some of the other ships we had (like a rover on the Mun) stayed saved.

Pretty discouraging :s

I attached the latest output log...I'm not really sure if this will have any tips: http://eugk.com/output_log.txt

I was thinking about this, instead of broadcasting the server information like KMP does (Server MOTD: string\nPort: int), it should be a json string, broadcasted to a default port which cannot be modified.

Example:

{
"result" : {
"server_name" : "A Test Server",
"server_address" : "127.0.0.1",
"server_port" : "6072",
"clients" : "1337",
"gamemode" : "career",
"subspace" : "MCW_VOTE"
}
}

Even if there was a command that cleared KSC of every active vessel. And the ability to set "nuke KSC" and dekessler on a timer, with a warning, would be nice.

I tried the latest dev version and when you press Shift+Enter, and type anything, it will only "record" the first key you've pressed.

I had it working, but it's deprecated since it's a feature.

We should get it onto 0.1.4 or wait 'till 0.1.5?

And the API? I know "exactly" how to do it so: make a dll with the functions instead. that way, we can, for example, have a function SendChatMessageToClient(ClientObject client, string message) and use it externally.

Something is causing multiple Kerbals to be left in orbit after an EVA mission. I do not see duplicates of my personal kerbals, but I see the kerbals of others, even long after they've disconnected from the server.

During 2-player testing the other person was sometimes disconnected, server log:
INFO Invalid DMP mesage from :49755
INFO Client x disconnected, sent CONNECTION_END to endpoint :49755

It happened 9 times in about 45 minutes. I was hosting the server and connecting locally. I'm not aware of any connection issues, stable ping around 50-70ms to the other player. Each time the other player was able to reconnect easily.

Development build as listed on the dmp build site:
Tag: d25ca7de9bb33c7bca66d81d2688c2aea6636e11
Build date: Sun May 18 05:50:35 UTC 2014

It appears from the client-side right now (Dev to Release) it gives EndWrite failure.
Server side it gives protocol mismatch.

Release to dev gives protocol mismatch.
Server side gives protocol mismatch.

It would be nice if the error message read something like:
Your verison x.x.x.x Server version x.x.x.x Update at xxxxxxxx.xx-xx.xxxx.

This causes major issues for players on smaller screens.

If you download a craft file from the SPH, it shows up in the VAB not the SPH.

If a scenario has been unlocked and then mods are added to the server that have parts from those scenarios then they cannot be unlocked. E.g:
Kerbal Engineer Redux adds parts to the start scenario.
When you attempt to unlock these parts clicking on them brings up the Research part and clicking research shows them as being unlocked.
Going to the VAB shows the parts as needing to be unlcoked despite the fact the already have been and going back to the R&D center shows them as being locked again.

Verrrry annoying. Missed a million captures this way. It also seems like aerocaptures are less effective than in single player. Perhaps because the warp rate is being forced to 1.5x and stopping atmospheric effects on a vessel? just a thought, as for not dropping you out of warp, that's assured.

This issue has happened to me once and my friend multiple times (in the ~3 hours that we played together):

Inability to exit the game, disconnect, or return to space center - the only way to leave appears to be alt-f4.

Nothing in particular seems to trigger it - all of the times we were just playing around in orbit, pretty close together I suppose. One time, I was at the space center and he was in orbit and couldn't leave. The other times, we were next to each other in orbit.

We are still able to fly our ships and whatnot...so the game is not "freezing". But you just can't leave :S

Wonder what could be causing this!

That way you could quickly click on a name to toggle it, and don't have to re-position your mouse to the right side of the screenshot to close it again.

Possibly only relevant to MCW_VOTE and my other feature enhancement suggestions (to be posted at the time of writing this - links to those related enhancements will be posted here).

Scenario

A KSP client side plugin needs to stop warp while another player has warp control or to prevent warp voting for a short period of time (and maybe a config option to set lock warp control for num seconds).

theoretical example

TAC life support mod detects that Jool Orbital station 1 is about to run out of oxygen (even though Bob Kerman is still 6 months away with the resupply, Charlie Kermans end of life is imminent).
If TAC decided to support DMP, it could hook into the DMP client and send 'HALT_WARP', 'Jool Orbital station 1 oxygen supply will run out soon'.
The server could then regain warp control and issue the following messages to all players:

If warp is already active, slow and stop warp:
"Warp has been halted - 'Jool Orbital station 1 oxygen supply will run out soon'"

If someone tries to gain warp:
"Warp is unavailable for num seconds - 'Jool Orbital station 1 oxygen supply will run out soon'"

This should give the players some time to address the situation, perhaps discuss or call for help in chat - and then finally continue warp voting.

Personal flags left on locations are not present after disconnecting and reconnecting.
