Can you tell me how linc-daemon works exactly? I have never used it.

Thanks in advance,

Dejavu :P. It seems just yesterday that Philip Tellis was tutoring me on how to use linc-daemon. I didnt thank him for his wonderful post. Anyway, its better to be late than never. Thanks Philip :)

Here is his original post:

I'm not sure about the rpm, I installed from source, but it should be the same. If my instructions don't work, then give me the output of rpm -q linc-daemon

Instructions:

After installing, you should have the following files:

/usr/bin/linc /etc/lincrc

if you do not have /etc/lincrc, then create it using the command:

touch /etc/lincrc

now, edit this file:

vi /etc/lincrc

My file looks like this:

# Config file for linc cablenet client srvaddr = 172.16.1.1 srvport = 6060 username = tellis password = xxxxxxxxxxx hwaddr = 00:E0:4C:00:03:42

you should change the settings to whatever your operator gives you. hwaddr is specific to your machine, you can use the ifconfig utility to find out:

/sbin/ifconfig

eth0 Link encap:Ethernet HWaddr 00:E0:4C:00:03:42 ^^^^^^^^^^^^^^^^^

next, you'll need to configure your resolv.conf file to use the dns server that your ISP gives you.

finally, I've attached a linc startup script to this mail. You should copy it to /etc/init.d and run the following commands:

chmod +x /etc/init.d/linc chkconfig --add linc chkconfig linc on

This will ensure that linc connects to the net when your machine boots up. To start linc immediately, run the following command:

/etc/init.d/linc start

to stop linc, run:

/etc/init.d/linc stop

other options can be got by running

/etc/init.d/linc

NOTES:

before you do anything, try and understand how things work. man linc man lincrc will explain a lot

You can also start linc by just running the linc program. This will start linc on the current console, but in the background. You will have to send it signals using the kill command, which IMO isn't very user friendly.

Subscribing to the linc-user's mailing list (on sourceforge) can help.

Sometime Today, AMR cobbled together some glyphs to say:

This may be a little off topic, but can some explain how cyberroam is able to block ur net connection until u sign in thru their client.

Their client contacts their gateway with your login credentials. This includes your MAC address and IP address. When this happens, the gateway enables routing for your MAC/IP pair.

I am not so sure about this because AFAIK cyberoam client only uses your MAC to authenticate. The server checks the MAC / IP combo with its records and enables routing for _only_ your IP and not MAC / IP pair. Since if it were enabling routing on the basis of MAC / IP pair then I wouldn't be able to use my connection as my MAC is totally different from what my ISP has bound my connection with. And I don't spoof my MAC. linc-daemon sends the expected mac while cyberoam client actually finds out the MAC through API calls.

My customer uses cyberoam 24x7 client for login and when I replaced his nic, I had to call them up to reset my mac address. Login not only checks the physical paramaters like ip and mac but also the username and password. Once password is authenticated, your user id is checked for account status and after all clear, your gateway route is active.

Rony.

Yes. But for the linux client i.e. linc-daemon there is no need to contact the ISP and ask them to reset the MAC. The client sends whatever MAC you tell it to in the login packet. As for windoze clients, well newer NICs have an option to specify the network address. You put in your old NIC's MAC in there and you're set ;)

Hmmm, this was possible for quite a few years. I remember seeing this option in Windows 95.

simple. the server doesn't route your packets until it receives a specifically encrypted packet from you. Thats why you can ping the server without signing in but you can't go any further ;)
