Hello all.
I use Debian and when I want to start Vidalia, it shows me an error:

"Vidalia detected that the Tor software exited unexpectedly."

I use netstat -nat | grep 127.0.0.1 and result is :

tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN

I used ps -A | grep tor and tor is not running. How can I solve this problem?

Cheers.

Are you trying to start the program as "root"? If not, "permission denied" is exactly what you should expect to get when trying to start a service on a port number below 1024 (including, obviously, port 443).

i use sudo command too but my problem not solved . I complete remove Tor and Vidalia too but problem is exist.

How can I solve it?

one easy thing to do is using tor browser bundle, thats how i use tor in my kali linux box.

just download tor browser bundle from tor site and as a normal user make command in the tor browser bundle directory : "./start-tor-browser"

browser in that version of tor has https everywhere and noscript installed, it has no flash or java plugins as those can leak ur ip address to people that try to track tor users.

I use Tor browser too and It is show me same erro

I found the problem. My problem is 127.0.0.1 .I can't ping it :/ . What is the problem and how can I solve it?

What does the command "ifconfig lo" say?

Ifconfig lo say me :

lo Link encap:Local Loopback
LOOPBACK MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

Your loopback address is down. I haven't run into that before myself, but I have read of it happening. I am not sure what configuration problem could be causing that, and don't have time at the moment to do research on it. You could try "ifup lo" *runn as root) and see what happens. But my bet is on "nothing" happening, since it's probably a configuration/setup error.
