pawn Код:

forward KickLog(string[]);
public IpLog(string[])
{
     new entry[256];
    format(entry, sizeof(entry), "%s\r\n",string);
    new File:hFile;
    hFile = fopen("ip.log", io_append);
    if (hFile){
        fwrite(hFile, entry);
        fclose(hFile);
    }
}

public OnPlayerConnect(playerid)
{
    new string[100], pName[24], pIp[20];
    GetPlayerName(playerid, pName, sizeof(pName)); 
    GetPlayerIp(playerid, pIp, sizeof(pIp)); 
    format(string, sizeof(string), "%s - %s \n", pIp, pName);
    IpLog(string);
    return 1;
