Static DNS entries in router?

[HavocXphere]

I want to do the same thing as the hosts file does, but router side. i.e. resolve certain URLs to a preset IP.

Problem is I can't find anything in the router page that allows me to do this. Its a Netgear DGN2000. I see static routes, address reservation etc, but I don't that it.

Failing that, is there a hosts equivalent file somewhere in the router when accessed via telnet? I vaguely remember that linux has something like that.

Thanks

Thanks Grim

I'm a bit uneasy about the cat style editing. If I create a backup like this:

cp /etc/hosts /etc/hosts.bck

then I should be able to recover from mistakes made, right? And the backup will survive a hard-reset?

 

[Grim147]

cat just display's the contents of a file,
echo "text" > filename (will write)
echo "test" >> filename (will append to new line)

reseting the router will probably get ride of anychanges , could be wrong . you can make a backup file if you want , or just take note or the original contents

edit: reason i used that method is because its very unlikley the stripped down linux distro will have any editors or anything like that

 

[HavocXphere]

hmmm...didn't quite work.

Managed to create a backup and add a line, but it doesn't actually resolve (used the equivalent line of what you did). Then I did a soft reset to see if it only reads in the hosts on boot...and that wiped the hosts clean and deleted the backup too.

I guess its not happening. Thanks for the replies nonetheless Grim.

I want to avoid running a box 24/7 just for this. Then I'd rather just edit each machines host file.
