By default, at least on the DG834Gv5, the option to add your own entries is not enabled.
Log into your netgear with telnet.
With a web browser, connect to http://your-modem/setup.cgi?todo=debug
Telnet to your modem: telnet
Create a new hosts file with local addresses:
mkdir /var/etc
cp /etc/hosts /var/etc/hosts
echo "192.168.1.10 www.myinternalwebserver.com" >> /var/etc/hosts
To check it works, restart the DNS Masquerade program:
killall dnsmasq
dnsmasq -h -n -c 0 -N -i br0 -r /tmp/resolv.conf -u r -H /var/etc/hosts
Making things permanent:
Now, there is a problem making this permanent as the root filesystem is 100% full, but what you would need to do is:
Mount the root disk read/write: mount / -o rw,remount
Copy the hosts file over: cp /var/etc/hosts /etc/hosts
Reboot
It would appear that on DG834Gv4 dnsmasq is not even present; dnrd is used instead, that also uses the /etc/hosts file as dnsmasq.
ReplyDeleteTo check if it works use
killall dnrd
dnrd -a yourLANrouterAddress -m hosts -c off -b -s dnsServer1 -s dnsServer2
or wathever command line your router is using as found by
cat /proc/PIDofDNRD/cmdline
where PIDofDNR can be found using ps | grep dnrd

On my DG834Gv4 the mount command fails so I'm unable to make the change permanent:
ReplyDeleteCannot read /etc/fstab: No such file or directory.
I could create a fstab file but have no idea what should go in it !
RE:DG834Gv4 and DG834Gv3 for that matter,
ReplyDeleteCreate the absent file system table using:
cat /proc/mounts > /etc/fstab
mount / -o rw,remount
ReplyDeletemount: Mounting rootfs on / failed: Permission denied
Any ideas ?
Anonymous (7 June 2011 22:19), worked?
ReplyDeleteI'm having the same problem as Anonymous (7 June 2011 22:19):
ReplyDelete# mount / -o rw,remount
mount:
Cannot read /etc/fstab: No such file or directory
# cat /proc/mounts > /etc/fstab
# mount / -o rw,remount
mount: Mounting rootfs on / failed: Permission denied
# cat /etc/fstab
rootfs / rootfs rw 0 0
/dev/root / squashfs ro 0 0
none /dev devfs rw 0 0
/proc /proc proc rw,nodiratime 0 0
ramfs /tmp ramfs rw 0 0
Any help here is greatly appreciated.
Thanks for the tutorial, it's working fine :)
ReplyDeleteIs there any workaround for the full filesystem?
Thanks again.
