Every needed to manually control host/domain IPs using the hosts file? Well, good thing most computers have a hosts file, but what do you do with other devices that do not support such a feature.
If you’re running a DD-WRT router, by using DNSMasq the DNS change will work for all devices that connect to your router, including mobile devices.
I got a Linksys WRT54GL v1.1 router that somewhat worked and somewhat didn’t: it booted alright (no led errors), responded to ping on its default IP (192.168.1.1), bot other than that, it did not respond on the web interface, nor telnet/ssh, nor dhcp.
I tried the 30/30/30 reset , tried TFTP recovery – nothing worked.
As it had the original Linksys firmware, at this point it was either a hardware failure or the only recovery course would be the JTAG reflash.
