Can't host UTnT server on Linux.

[Mysyk]

Hello. I have a problem. I want to host UTnT server on Linux OS. I made everything by instructions.

Code: Select all

File - utnt.sh. It contents those:
#!/bin/sh
  ZNPATH="/root/doomgames"
  $ZNPATH/zandronum/zandronum-server -host \
  +invasion 1 \
  -port 10679 \
  -iwad $ZNPATH/iwads/DOOM2.WAD \
  -file $ZNPATH/wads/skulltag_data_126.pk3 $ZNPATH/wads/skulltag_actors.pk3 $ZNPATH/wads/UTNT_INV.WAD\
  +exec $ZNPATH/cfg/utnt.cfg 

[Dark-Assassin]

Is you'r wads and cfg folders located at /root/doomgames/ or /root/doomgames/zandronum/ ?

If the former, I don't really see why it won't work.
If the latter, it should be obvious where you went wrong.

Also on line 7, add a space between the UTNT_INV.WAD and \
Just in case.

Sorry. But you must say Are your WADs. :)
My PWADs are in /root/doomgames/wads/ and IWADs are /root/doomgames/iwads/ and cfg(ini) files are in /root/doomgames/cfg/ respectively.

If the former, I don't really see why it won't work.
If the latter, it should be obvious where you went wrong.

I know about space on line 7. :) I edited utnt.sh file many times. Problem began with Zandronum. It worked fine all time with Skulltag.

My exact UTnT script

Code: Select all

#!/bin/bash
#first map is tnt01
./zandronum-server -iwad /opt/zand/doom2/doom2.wad -file /opt/zand/doom2/tutnt-v107.pk3 +exec /opt/zand/skulltag.ini +skill 3 +sv_weaponstay true +sv_itemrespawn true -host +sv_website www.l1tcomputing.com +sv_motd "www.l1tcomputing.com" +sv_hostname "L1T---Ultimate-Torment-&-Torture-Coop" -port 10668

Also giving us the error you get would help a lot.

[Mysyk]

I encounter one of two errors. utnt.sh has

Code: Select all

#!/bin/sh
  ZNPATH="/root/doomgames"
  $ZNPATH/zandronum/zandronum-server -host \
  +invasion 1 \

That's a memory allocation error. Are you sure you have necessary RAM available to run the server?

[Dark-Assassin]

Type free -t -m and paste the result here. Preferably in a code box.
The results shown will be shown in MB.

I had suspect such feature. Ok. Here is a log.

Seems you only got ~32MB free RAM. You should also allocate some SWAP so everything isn't all you'r RAM.
You can find tutorials about that around, I'd suggest allocating something from 512MB to 2048MB.

Anyway, Skulltag/Zandronum requires an average of 128MB of RAM to be able to host a server.
It may use much less on idle, but it leaves room for players.

You cannot use SWAP for something more dynamic as it is not fast enough, but it is good for the less dynamic data storage.

[Mysyk]

Ok. Thank you. I have Zandronum and ZDaemor servers. Also I set Red Eclipse server.

[Mysyk]

Yeah. You were right. I need more RAM for my server.
Thread is no more actual.

If you are low on RAM, you can set sv_disallowbots to true. This considerably reduces the memory usage of the server since the bot nodes are not built then.

Shouldn't this be off by default (until a bot is added)? Or would that require resetting the map?

The bot nodes are build when the map is loaded. Possibly you could rewrite the system to do this on-the-fly when the first bot is added.

That sounds like a good idea. Although depending on how much memory would be saved (i have no idea what the figures are, I'll have to run some tests for myself), it may not even be worth the effort, if it's a negligible amount of savings.

Where in the source is the botnode-building behavior located?

EDIT:
On second thought, maybe it might be easier to just make a change to Doomseeker and have it use sv_disallowbots by default unless the player chooses to start the server with bots via the server setup dialogue. If they try to add bots after the server has already been launched, they'll be told that they need to reset the map in order for the change to take effect.

Hosts who choose to add bots appear to be a minority anyways, and the only servers that I see where bots are used are (no offense) servers that I would never play on. I think the benefits far outweigh the risks when it comes to disabling the building of bot nodes (online) by default.

[Dark-Assassin]

I don't think it would have mattered much with an average of 32MB of RAM left.
As soon as a player would join, it would crash the server, that's if he is lucky for it to not have while initializing.

[Espio]

If you are low on RAM, you can set sv_disallowbots to true. This considerably reduces the memory usage of the server since the bot nodes are not built then.

Shitting me? Wish I had known that earlier... better late than never.

Whoa. :) I had to knew it early. Is set sv_disallowbots to true by default? I run my servers via Unix OSes.
I just have checked my configs. It is true.

Don't forget about Linux users. You should notice that thread about servers on Linux.

As I said before it is due to low amount of physical memory.
