danas je najnovija stvar da je linux iptables dodatno prolupao, pa sada iptables -L (-t nat) nikada da završi ?!?! da nisam nešto u firewall stavio juče što ga je sblaznilo

root@router-wan-sa-1:/tmp# mtd -r write openwrt-brcm-2.4-squashfs.trx linux

Unlocking linux ...

vraćam config

hernad@nmraka-1:~/Desktop$ scp config.tar root@192.168.1.1:/tmp

root@OpenWrt:~# tar xvf /tmp/config.tar

root@OpenWrt:~# reboot

ne bih ja bio ja da nešto ne uprskam

root@OpenWrt:~# cd / <<<<<<<<<<< nedostajalo
root@OpenWrt:/# tar xvf /tmp/config.tar

da li ću morati radi ovoga reflashirati router (da li sam izgubio 166 KB ?

root@router-wan-sa-1:~# du -s -h

izgleda da nisam

ovo treba prebaciti na /mnt/1 i simbolički linkovati

root@router-wan-sa-1:/tmp# du /usr/lib/ipkg

0    /usr/lib/ipkg/lists
35    /usr/lib/ipkg/info
40    /usr/lib/ipkg

dodao net destinaciju u ipkg

/etc/ipkg.conf:

src snapshots http://downloads.openwrt.org/snapshots/brcm-2.4/packages
dest root /
dest ram /tmp
src X-Wrt http://downloads.x-wrt.org/xwrt/kamikaze/snapshots/brcm-2.4/packages
dest net /mnt/1

instalirao snmp-utils:

root@router-wan-sa-1:/tmp# ipkg -d net install snmp-utils_5.1.2-2.3_mipsel.ipk

instalirano ovdje: /mnt/1/usr/bin/snmpstatus , itd ...

utvrdio da bez dnsmasq name server ne radi, zato sam morao vratiti dnsmasq

1. ipkg install -t net /tmp/dnsmasq*ipk
2. ln -s /mnt/1/usr/sbin/dnsmasq /usr/sbin
3. root@router-wan-sa-1:/tmp# ln -s /tmp/resolv.conf /etc/resolv.conf

nakon restarta nameserver na router-u funkcioniše ....

.... hah ne funkcioniše ipak :(

root@router-wan-sa-1:~# cat /etc/resolv.conf

nameserver 195.222.32.10
nameserver 195.222.32.20

joj ja sam pogriješio sintaksu u resolv.conf-u, nema potrebe za dnsmasq ....

root@router-wan-sa-1:~# cat /etc/resolv.conf

nameserver 192.168.45.250

takođe ću izbrisati dnsmasq

root@router-wan-sa-1:~# ipkg remove dnsmasq

Removing package dnsmasq from net...
Done.

tcpdump, snmpd, xwrt-webif treba instalirati na "-d net" da ne zauzimaju nepotrebno prostor
