 Posted: Mon Oct 29, 2007 1:42 pm Post subject: resolv.conf overwriting |
 |
|
I have problem with net scripts. I'm connected to to wireless networks through 2 interfaces - wlan0 - source of internet, open network , obtaining IP by dhcp. And eth1 - connected to home wireless gateway, with WPA via wpa_supplicant, at the moment it isn't connected to Internet, but I need it to connect other boxes.
Problem is that eth1 is overwriting dns'es in resolv.conf and ocassionally default gw. I'm running once it happen cat /etc/resolv.bak > /etc/resolv.conf but don't like such workaround.
I changed IP to static for home network but it still happens once a few minutes:
| Code: |
nusch@nuschbox ~ $ cat /etc/resolv.conf
# Generated by net-scripts for interface eth1
domain nuschNET
|
Here is my conf.d/net:
| Code: |
...
modules_eth1=( "wpa_supplicant" )
modules_WantToChallenge=( "wpa_supplicant" )
modules_eduroam=( "wpa_supplicant" )
wpa_supplicant_eth1="-Dwext"
config_eduroam=( "dhcp") #used with eth1
config_Security_Lounge=( "192.168.10.3/24") #used with eth1
dhcp_Security_Lounge=( "-R" )
config_WantToChallenge=( "dhcp" ) # used with eth1
config_wlan0=( "dhcp" )
...
essid_wlan0="ISP"
mode_wlan0="managed"
iwconfig_wlan0="rate 1M"
...
|
If it's possible would like to obtain IP through DHCP but ignore gateway and dns's from it. |

Does
help? I don't get the "Security_Lounge" stuff in your config. Whats about this?
Btw can you please try to manually retrive an address for both interfaces using
| Code: |
dhcpcd wlan0
dhcpcd -R eth1
|
"-R" prevents dhcp to overwrite the resolv.conf. You maybe have to kill the dhcpcd
beforehand...

It's ESSID, I'm using laptop in different places and want to disable dhcp only for this specified one.

I can also do
| Code: |
rc-update del net.wlan0
rc-update del net.eth1
iwconfig wlan0 essid ISP
iwconfig wlan0 rate 1M mode managed
wpa_supplicant foobar foobar foobar eth1
dhcpcd -d wlan0
|
But gentoo is not slackware and I want to use bulit-in scripts for this  |

Sometimes its nice to try a certain idea on commandline before trying to fiddle
around with the config stuff...
