I've recently bought a VPS for recreational activities and I wanted to set up a SA:MP server so I could test things on it. The OS is 64 bits Debian v7 (Wheezy) and the server starts correctly and all of the plugins are successful in loading. But, when a player types a command I have it logged to a massive log file. Therefor, when the player types the command, the server crashes.

I have tested this on my local windows machine, and it works properly.

I was getting:

Код:

samp03svr: amx/amxfile.c:222: fputs_cell:
Assertion `fp!=((void *)0)' failed.

But then I installed crashdetect.so and now this is the full error log when a player types a command.

Yes I have chmodded my entire SA:MP directory to 777, that is not the issue. And as I said, the issue is most likely with logging as the server works fine up until the point where the commands are logged.

Here are the two callbacks mentioned in the error log:

PHP код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    return 0;
}
public OnPlayerCommandReceived(playerid, cmdtext[])
{
    Array[0] = 0;
    format(Array, sizeof(Array), "[command text] [%s] %s", GetName(playerid), cmdtext);
    printf("%s", Array);
    Log(0, Array);
    DeletePVar(playerid, "LastTyped");
    return 1;
} 


Any ideas?

Show us the Log function, something is wrong with fwrite.

But it is a terribly bad idea. Besides, if the file exists in the folder but the server does not have permission to write in it then it can still be the issue. Execute these commands in the main server directory, as the user that you run the server with (hopefully not root!):

Код:

whoami

Код:

ls -la

Код:

ls -la scriptfiles

Post results.

    new File:logfile, logstring[300];

    switch(type)
    {
        case 0: // Server
        {
            logfile = fopen("Logs/Server.log", io_append);
            fwrite(logfile, logstring);
            fclose(logfile);
        }
         }
} 


Like I said, this works on windows.

Aw man, running as root.

Do the same for the scriptfiles/Logs directory, please. I need to see the permissions on the actual file itself.

This server is private meaning I never intend to open it to the public. I do not care about the security or efficiency of these methods for this project. In the event I did (which will never happen), I know the correct security measures to take on linux to run all programs on a user-base level.
