Can some one explain to me what are the meanings of tunnling and squid in linux?

Moreover, I read about configuring the system to send internet data thru ppp0 and receive it on ppp1 and assign ppp0 to the modem and ppp1 to another device, in my case the dvb card. Is this true? How can I do it?

Salam

well squid is a web proxy server.

tunneling is as far as I understand it moving traffic for a certain protocol inside a connection established by another protocol.

so for instance if you have an insecure plain text protocol you can tunnel it through ssh to secure it.

Thanks alaa. This means I misunderstood the term tunneling. I thought I can tunnel the internet back flow thru another device. I appreciate your quick reply as usual alaa.

I wish some one can answer the second quetion about ppp0 and ppp1.

Salam

I think I know that the answer to the first part of your seond question is right it is true, no idea how its done though.

I have done an experiment with dvbtune and the pptp:

First dvbtone did the following:
[root@localhost dvbtune]# ./dvbtune -c 0 -f 11449000 -s 27531 -p v -n 3013 -D 3
Using DVB card "Zarlink MT312"
tuning DVB-S to L-Band:1107311556, Pol:V Srate=27531000, 22kHz=off

[root@localhost dvbtune]# ifconfig -a dvb0_0

[root@localhost dvbtune]#

Second, I established a pptp connection with EOL and got the following:

Using interface ppp1
pptp-php-gtk: monitoring interface ppp1
connect: ppp1 <--> /dev/pts/2
CHAP authentication succeeded
local IP address 10.129.0.96
remote IP address 193.251.135.97
pptp-php-gtk: pppd process exit 0
pptp-php-gtk: routes added to remote networks
route add -host '193.251.135.97' dev 'dvb0_0'
SIOCADDRT: No such device

pptp-php-gtk: command failed, exit code 7
pptp-php-gtk: connected

I do not know why it says no such device here while in the first step it tells me every thing is ok! Can you figure out the reason from the data shown above?
