Sorry.. I missed your earlier post..

can you confirm that /etc/resolv.conf still contains the google DNS ? ( 8.8.8.8 )

also try and ping without a DNS look up

Code:

ping www.google.com
PING www.google.com (173.194.34.84) 56(84) bytes of data.

Code:

ping 173.194.34.84

I'm. lost.. I'll have to have a think..

can you use windows?

then note the ip/ routing and dns

yes i am accessing the same net through windows.. same ip.. same gateway...
see in the above comment when i checked the route it is showing * at the place of gateway.. what does that mean? Is there a problem with the client?

Firerat · 09-06-2013, 08:16 AM

actually, that does look a little messed up

try this

Code:

ip route add default via 10.30.6.1 dev em1

soorajthechamp · 09-07-2013, 12:37 AM

Thanks A lot firerat Sir.
It finally worked. I am accessing the forum from Linux

this command sets the default gateway for em1 as 10.30.6.1 right?
I am your follower now

Am a newbie in Linux. Please guide me how to be a pro like you.

lets not get too excited...
I failed to notice it myself

anyway , the next thing to do is make that convenient.

I'm not familiar with Fedora , I know it sometimes does things a little differently

I suppose the easiest way is to simply add that "ip route add " to a script that first starts ./crclient

example
$HOME/bin/StartNet.sh

Code:

#!/bin/bash
/path/to/crclient -u sooraj -i em1
ip route add default via 10.30.6.1 dev em1

Code:

chmod 700 $HOME/bin/StartNet.sh

but ultimately having your network manager it 'manage' it would be better

So basically you want me to create a Shell Script file to do it in one time right?

Firerat · 09-07-2013, 02:14 PM

that is up to you,
but ultimately it will make life a little easier

better still would be integrating it with Fedora's networking scripts, so you need not do anything when you boot.

I'll take a look at Fedora after the weekend,

edit:
actually, that 'script' I posted, at least the ip route add is going to need root.

and thinking about it, did you try crclient as root?
with root it might set the routing up itself.

yeah i did it with root too... it still was not doing that...
i dont know how to integrate it with networking script :|
m noob :P

i would put the startup command in the systems /etc/rc.local file.

or you can put an @reboot declaritive in the users crontab.

else you can add it to the users .bash_profile but it will only run when that specific user logs in.

Firerat · 09-07-2013, 03:18 PM

For now run that 'script', slight modification to get root for ip route

Code:

#!/bin/bash
/path/to/crclient -u sooraj -i em1
su -c "/sbin/ip route add default via 10.30.6.1 dev em1"

alternatively, if you have sudo

Code:

#!/bin/bash
/path/to/crclient -u sooraj -i em1
sudo /sbin/ip route add default via 10.30.6.1 dev em1

I will look at Fedora with a view to better integration , but won't be until next week.

sir first two lines went over my head.
i understood the last one a bit

Actually am new to linux. Installed it last month itself for the first time

Firerat · 09-07-2013, 04:02 PM

the /etc/rc.local is a good way to start things on boot,
rc.local is executed on boot , after all of the other boot scripts have run.

it runs as root so no problems with the "ip route add"

I like the crontab, never thought of that myself.

as root, crontab -e
and add the following lines at the bottom

Code:

@reboot /path/to/crclient -u sooraj -i em1 && \
        /sbin/ip route add default via 10.30.6.1 dev em1

some background on cron{tab}
https://en.wikipedia.org/wiki/Cron

cron is useful for doing boring stuff., automatically

for example I have this to update flashplugin

Code:

0 1 * * * /usr/sbin/update-flashplugin-nonfree --install

I think it was Evo2 who pointed out to me that package mangers don't keep flash updated. so I added that cron job to do it for me.
