Ubuntu Security :: Connect Firefox To Tor?
Apr 11, 2011I followed instructions for installing vidalia and polipo and everything seems to be working ok, but I cannot connect to tor from firefox using torbutton. I didn't edit configurations other than downloaded those for polipo, as described in the link above.I read that somebody got it working with foxyproxy better than torbutton, but torbutton is customised specifically to enhance tor, so I'd prefer to use it unless there issomething better.torbutton test fails with: Quote:Tor proxy test: Local HTTP Proxy is unreachable. Is Polipo running properly?Message log from tor:
Code:
Apr 11 00:39:51.187 [Notice] Tor v0.2.1.30. This is experimental software. Do not rely on it for strong anonymity. (Running on Linux i686)

Ubuntu :: Firefox Internet Wont Connect

Ubuntu Security :: Internet Logs - Privacy With Firefox
Jan 8, 2010These files seem to contain browsing history:
~/.mozilla/firefox/xxxxx.default/cookies.sqlite ~/.mozilla/firefox/xxxxx.default/formhistory.sqlite ~/.mozilla/firefox/xxxxx.default/downloads.sqlite ~/.mozilla/firefox/xxxxx.default/places.sqlite ~/.mozilla/firefox/xxxxx.default/places.sqlite-journal
~/.mozilla/firefox/xxxxx.default/Cache/
Therefore I have cleared these files using an erasing program. I am wondering if there are other locations where such log files are stored for Internet browsing. I have looked in the /var/log directory and cannot see anything - for example doing a grep on http:// after browsing in Firefox does not reveal anything obvious.
Fedora :: F15 / Firefox Cannot Connect To Internet
Jun 28, 2011I have a freshly installed dual boot Win 7 and F15. Windows 7 gets on the internet no problem, so does this RHEL/FF machine, iphone too, but F15/Firefox no joy. it's showing me connected to my network just fine. I'm pretty sure it worked at some point because I did my software updates and I have a saved bookmark, though I don't remember exactly.

OpenSUSE Network :: 11.4 - Firefox Fails To Connect To Internet (Skype Intact)
Jul 26, 2011I have a Lenovo S10e netbook running a pretty clean version of 32bit opensuse 11.4, with very few standard patches since I installed it all those moons ago. The problem is that firefox cannot connect to the internet, the odd bit is that skype has no such problems. Are there any network related functions that that typically go screwy that might cause such a problem? The netbook really hasn't been used much for tinkering to have 'accumulated' a problem, but I'm about to give it to the extremely non-technical parents in law and cannot have it misbehaving, especially not as they are in a different country.

Apr 1, 2010After reading a lot about networking and security I decided to check the security of my own ubuntu box. So I went installing Nmap and discovered that port 139 was "open". Since I 'd read how to use ufw I created a deny rule for port 139. After a second scan with Nmap it still said that port 139 was open as shown below.

Ubuntu Security :: What Ports Are Open And Why
Jul 27, 2010I'm locking down my laptop. I know I can use a firewall to ensure nothing gets through that I didn't catch, and I certainly plan on using one, but in the meantime, I want to know what exactly is running on my system.
nmap localhost returns:
Code:
james@james-linux:~$ nmap localhost
Starting Nmap 5.00 ( http://nmap.org ) at 2010-07-26 23:33 CDT
Warning: Hostname localhost resolves to 2 IPs. Using 127.0.0.1.
Interesting ports on localhost (127.0.0.1):
Not shown: 994 closed ports
PORT STATE SERVICE
25/tcp open smtp
111/tcp open rpcbind
139/tcp open netbios-ssn
445/tcp open microsoft-ds
631/tcp open ipp
2049/tcp open nfs
Nmap done: 1 IP address (1 host up) scanned in 0.18 seconds
However, I know that localhost goes back to the loopback interface, 127.0.0.1. So, to see what was really open, I ran nmap 192.168.0.108, which is my laptop's IP at the moment.
Code:
james@james-linux:~$ nmap 192.168.0.108
Starting Nmap 5.00 ( http://nmap.org ) at 2010-07-26 23:33 CDT
Interesting ports on 192.168.0.108:
Not shown: 996 closed ports
PORT STATE SERVICE
111/tcp open rpcbind
139/tcp open netbios-ssn
445/tcp open microsoft-ds
2049/tcp open nfs
Nmap done: 1 IP address (1 host up) scanned in 0.14 seconds
Now if I understand correctly, I can attribute 139 and 445 to my Samba share. That I'm okay with. What I don't know is 111 and 2049. Does anyone know what these ports are, what's running on them, and how I could turn them off, supposing that they are a security risk?
Ubuntu Security :: Ports 21 / 110 And 143 Are Open?
Mar 18, 2011I'm getting heat from the head networking office that ports 21, 110, and 143 are open. I can telnet to those ports from a remote machine (not localhost) and get a prompt. There does not seem to be anything listening on those ports according to netstat. I've tried using iptables to discard all traffic to a from those ports but I can still telnet to them. This is a lucid desktop machine.

Ubuntu Security :: Keeping All Ports Stealthed?
Sep 26, 2010I know how to forward ports in my router. Now I need to open a port to help with testing a project and no matter what I've tried, every port under 1055 shows up as stealthed (with 1-71 closed) according to Shields Up! I'm happy to run it at a port > 1024, but whatever I try also shows up stealthed. I even tried (briefly) turning on DMZ and still the same thing. My ISP swears that they only block port 80, 21 and 25, none of which I'm trying to use. UFW status reports inactive and I'm not using firestarter. I'm not running any other server (apache, light speed etc). If it's not my router and it's not my ISP, and there's no other server apps running, then that kind of leaves Ubuntu as far as I can see,

Mar 30, 2011We do NOT support samba on our Unbuntu servers but still zillions of windows machines are constantly trying to connect on the SMB ports. I've added a rule that drops access to destination ports 137-138 and that seems to work. But it creates many many log entries documenting that the packet has been dropped. I've been researching and cannot come up with a way to suppress logging for these drops.

Dec 2, 2010looking at my router logs i've noticed for the past while a range of source ports from 60000 to about 65000 from my source external ip to destination external ip always on port 80. I have 3 boxes on this network and this only seems to happen when i connect the one laptop. I even reinstalled the distro downloaded from trusted source but the router is still logging this.. netstat -ntulp shows nothing operating in this range. chkrootkit shows nothing.. Was thinking maybe someone was spoofing the external address but it's been happening on network startup for a month now

Ubuntu Security :: Restrict Open Ports In Firestarter When Using Torrents?
Aug 19, 2010I am trying to configure Bittorando and iptables using Firestarter. I have got it working but am concerned about security holes.
Let me explain.
AIUI, the Bittornado program contacts the "tracker" on various ports which (from the previously blocked connections in Firestarter) ranged from 4664 to 65532. Therefore, currently I have set this range to be open to allow downloads of the torrent.
However, this seems, IMHO, to devalue to point of having a restrictive exit policy for Firestarter since now virtually all ports are open. I can see nothing on the Bittornado client to restrict the outgoing ports although the "listening" (incoming) ports can be restricted.
I would prefer to have my system locked-down so that the minimal number of ports are open to initiate external connections so is there any way to achieve this with Bittornado?
Ubuntu Security :: High Numbers Ports Opened Transiently
Nov 5, 2010While (attempting) to set up ssh on a couple of machines (not this one) I've noticed that I keep getting some strange unknown ports showing as open on my PC when I do a port scan on its address. They are only opened transiently, they are all high numbers eg 33348, 41147, 50370 etc. I have opened no ports on this machine at any time and ufw is set to deny all incoming.
