[tor-relays] Questions about GUI monitor

Dear Sir/Madam:

My system is Debian 32bit, Tor non-exit bridge.

1. For Debian, is there any pure Tor service monitoring and analyzing software for the local machine (not the entire Tor network), with/without a GUI ?

2. Does "Vidalia" really end developing? May I ask why? May I install the "Vidalia" which is still could be found in the Debian apt system?

3. https://www.torproject.org/projects/projects.html.en "orlib" the link is dead.

4. About "Tor2web", are there any clearer figures and docs which could explain the security differences between "Tor" and "Tow2web" ? Especially for the client.

Thank you.
