1. I've already have logfile "2". I can't see the log file. (Should it be in fs_game?)

.sh start file
Code:
cd /home/cod4/server
LD_LIBRARY_PATH="/home/libcod/mysql" LD_PRELOAD="/home/libcod/libcod4_1_7.so" ./cod4_lnxded +set dedicated "2" +set net_port "28961" +set fs_basepath "/home/cod4/server" +set fs_game "mods/nl_zom" +exec zom.cfg +map_rotate
.cfg file
Code:
set rcon_password "testtest"
set sv_hostname "^4`^9nL^4.^7Zombies^4*"
set g_allowvote "0"
set sv_pure "1"
set developer "0"
set g_password ""
set sv_floodProtect "1"
set sv_maxPing "0"
set scr_drawfriend "1"
set scr_forcerespawn "0"
set scr_killcam "1"
set scr_teambalance "0"
set sv_timeout "60"
set sv_kickBanTime "300"
set g_no_script_spam "1"
set g_antilag "1"
set sv_voice "0"
set com_hunkmegas "512"
set sv_punkbuster "1"

set sv_maxclients "24"
set sv_privateclients "0"
set sv_privatePassword ""

set logfile "2"

set sv_mapRotationCurrent ""
set sv_MapRotation "gametype dm map mp_crash"

2. Where can I get 1.7a patch?

3. "q3dirtravfix.so" fixes that player can't download gsc files from a server by command "/download mod\maps\mp\gametypes\tdm.gsc"

4. How to disable shot-through walls?
