New firmware - dnsmasq

[Oleg]

Guys, I've prepared the new firmware version. WebCam stuff not tested, so please check it and let me know if something wrong with it.

Differences with previous: Replaced dproxy & udhcpd with dnsmasq to support both static leases and dhcp/dns integration (so you can now resolve host names based on their dhcp names); replaced kernel modules with 2.4.20 version except the printing stuff (webcam stuff not verified!)
In order to use static leases/hosts you will need to perform this steps:
1. Connect to router using telnet;
2. Write the static hosts count & entries to the flash (use /etc/hosts format)
nvram set etc_hosts=3
nvram set etc_hosts0="192.168.1.1 wl500g"
nvram set etc_hosts1="192.168.1.2 laptop"
nvram set etc_hosts2="192.168.1.3 foo"

3. Write the static leases (use /etc/ethers format)
nvram set etc_ethers=2
nvram set etc_ethers0="00:11:22:33:44:55 192.168.1.2"
nvram set etc_ethers1="00:11:22:33:44:56 192.168.1.3"

3a. Also it is a good idea to change the DHCP server settings to not include addresses specified for static leases
4. Commit the changes using
nvram commit
5. Reboot the rooter using
reboot

Oleg, thanks a lot for the new version! I have just tested it with my Creative Labs WebCam 3. It seems the behaviour is the same as I described couple months ago. The problem with WebCam initialization during reboot still persists.

Good news is what it works. As for reboot - the problem is not with the cam driver, but with usb subsystem. It's seems drivers timed out waiting for cam - possibly cam still initializing when linux queries it...

Hey folks,
First of all, congratulations on your great work Oleg! I was looking for addver to make my custom fw work, and found this forum, that was awesome!
I got the -2 version of Oleg's work, and installed it yesterday, and my site is offline today, I would find ou what heappened, as soon as I get home, but I guess the pppoe went down becouse of the idle connection... never heappened before, but now I have the telnet to inspect it
My main aim on trying to make a custom fw was to make an watchdog to the connection. My isp disconnect me from 12 to 12hr, to compute the traffic accounting, normally my 500g detect and reconect it, but, in 1% of the ocurrences it doesnt notice that the connection was dropped and I get offline till a cold reboot take place. Usually I can check it every night, but last time it was up for more than 90 days, and gone down when I was in vacation 10.000km from home, and found myself without email server
I would ask if someone knows how the reconnection takes place? Its about the watchdog ? Or some kind of dial on demand? I'm reading all those scripts in the filesystem, but its not so clear yet... I've seem pppoecd on watchdog.conf, but it doesnt seem to reboot when the connection is dropped...
I'm planning to put a ping default router from time to time, and kill ppoecd if it fails... any better tip?
Another issue is about the upnp, it seems to dont work very well... I havent tryied with the last fw from Oleg yet, but heard from some friends that upnp on linksys routers works much better!

I wrote to much I guess...
Cya guys arround...
Fábio.

I'm recommending you to update to 1.6.5.3-5 version - previous does not work correctly due to changes in busybox default PATH.
As for watchdog - it's monitoring the existance of the processes listed in the watchdog.conf and does do anything for reconnect.
As for connection/reconnection all the stuff are controlled by pppoecd daemon which is the pppd with pppoe plagin in fact.
As for your problem - pppd daemon is the weird thing... You can dig onto it using linksys wrt54 sources. The simplest solution is to write the script which will ping the default dns server or something and reboot if it can't reach it for some period of time.

Regards,
Oleg.

Hey Oleg,
In order to do such changes I would like to customize your -5 version, and would like to know which are the sizes of vmlinuz and cramfs...
Actualy I could figured it out if the kernel was the same as original and knowing its size and trailler size, but as an fc said the kernel has been modified I dont know its correct size...
Could you tell us ?
Thanx a lot!
Fabio.

[Oleg]

Kernel are left as is - it's from the ASUS firmware. But anyway I'm suggesting you to download the firmware sources and modify them rather than do packing/unpacking. The Makefile will add the required things to your firmware.
You can also try tools provided by RCR and available here - http://files.wl500g.info/asus/wl500g.../wltools-1.tgz
