Ubuntu :: Why Thunderbird May Be Blocked From Sending
Jul 18, 2011
im using the latest version of thunderbird, & can receive messages ok but cant send.
it just says "sending....." & nothing else. yesterday I left it for over an hour - nothing happens.
I've been advised it may be with my firewall (I do not remember setting one up on this PC - my other Pc broke the last few days ago)..
Q1. How do i know if i have a firewall installed on Ubuntu.
q2. How do i tell it to allow Thunderbird to send ?
Q3. any other reason why Thunderbird may be blocked from sending. (the server settings on thunderbird are OK )

We have a spam in our network and we installed antivirus in all our systems and cleaned the virus from all pc's after that i had removed my ip from the database of blocked ip's but still my ip is blocked for sending spam i don't know from which pc the spam is going on the internet.
so i have a question that my proxy server is redhat linux and as a newbie i don't know the command's to find out which pc is creating large bandwidth to the internet. If you tell the command how to see which pc is sending spam then i will discard that pc. Also i want a strong firewall to stop spam activities.

I have two accnts in Thunderbird 3.1.10 in Lucid 64bit - gmail and itt-tech.edu (smtp.live.com). I removed apparmor because of the bug not allowing the file system to be mounted. I can send via gmail, not smtp.live.com. Smtp settings are correct. Any security package setting that might be hindering this mail send action?I have UFW installed.

Thanks to Lucid not working properly on i845, i855 and other 8xx chips, had to re-install Karmic on my mum's computer.I saved all the data from her old install and I ve managed to get all her old emails from thunderbird, but I cant import her address book.In Thunderbird/tools/import/addressbooks it only allows importing of LDIF, .tab, .csv and .txt files, but I cant find any of these files in any of the Thunderbird, .Thunderbird, Mozilla-Thunderbird or Mozilla folders in Home folder or anywhere, all I can find is "abook.mab" which IS supposed to be her address book, but when I try and import it the entries are blank and/or indecipherable (prob cos not a compatible file type).
Its one of those "simple" things to do, thats taken hours and hours of time, but that I cant actually find out how to do.

I had a portable apps version of Thunderbird (windows) that runs off a thumb drive and wanted to take the settings and transfer them to my Thunderbird that's on my Linux computer.
This is what I did:
First, I installed thunderbird on my Ubuntu 10.04 Linux box and opened it, and closed it (so that it would create the /home/<username>/.thunderbird folder in the user account).
Then, I renamed the linux /home/<username>/.thunderbird folder to .thunderbird_ORIGINAL
Then, I created a new /home/<username>/.thunderbird folder
Then, I took the windows e:ThunderbirdPortableDataprofile folder and copied it to the /home/<username>/.thunderbird folder.
Then, I looked into the /home/<username>/.thunderbird_ORIGINAL folder and wrote down the name of the folder with the ".default" extension.
Then, I renamed the profile folder (that came from the windows e:ThunderbirdPortableData folder) "<name-I-wrote-down>.default".
And then, I copied the profiles.ini folder from /home/<username>/.thunderbird_ORIGINAL to the /home/<username>/.thunderbird folder.
I opened up Thunderbird in Linux and everything seems fine! (I'll definitely be keeping a backup just in case)
My question is: is this fine and dandy, or a recipe for disaster?

I run version 10.04 GNOME. My problem is (after substantial searching) that I need to have both users ('juliusz' and 'sarah') running Thunderbird but with the same profile (settings, email, accounts etc. preferably of 'juliusz'). The only results on the internet are share Thunderbird between Windows and Ubuntu.
I have two users juliusz and sarah. I need either of them to have the same profile, always in synch whenever they logon to own account. When I tried to edit sarah's /home/sarah/.mozilla-thunderbird/profile.ini by inserting: Path=/home/juliusz/.mozilla-thunderbird/xxxxxxx.default after i run Thunderbird for 'sarah' I get message: "Thunderbird is already running, but is not responding. To open a new window, you must first close the existing Thunderbird process, or restart your system." I checked with "ps aux" there is no Thunderbird running in sarah's session. There is no Thunderbird running in juliusz's session when I reloged to juliusz.

I have installed 11.4, and it seems (seemed) to work OK so far. I installed Thunderbird via the opensuse "1 click install". the installation ran smoothly, but now a click on the Thunderbird icon does not activate any mail client; the only success is that Thunderbird icon jumps joyfully and then disappears.

So I set up an Ubuntu 10.04 server with apache2 installed, but for some reason I can't get to it from my browser. the iptables have all changed directories in 10.04 so I can't find the iptables. Apparmor wasn't the problem. The network hard ware is not the problem.There is something inside of 10.04 that is blocking port 80. I can ping it all day using the ip address but when I ping it useing http://ipaddress it can't find the host

I can't seem to remotely SSH or VNC into my machine. If I'm on the LAN and try accessing via LAN IP, it works fine. If i go in through a remote address (my dyndns) or even my home IP, I can't connect (yes, all of the ports are forwarded, I've triple checked this multiple times). Interestingly enough, port 80 works just fine. It would seem as though some sort of firewall is blocking me. I've done this plenty of times before with various machines, and this has me quite perplexed.

I dont know how, but somehow all the ports on my comp appear to be blocked except for 24, for ssh and 5900 unknown. I can connect to the network, but as far as I can tell, I'm powerless to do anything. No webpages load, I'm typing this on my phone.

I am trying to use Bittornado with iptables via Firestarter. Previously, I had no problems, but now I have started using Firestarter, traffic is blocked. AIUI, after selecting the .torrent file, the client (me) connects to the tracker. In Firestarter, I see that my IP is trying to connect to various ports, all of which are blocked.I assumed the problem was that because Firestarter has a restrictive outbound traffic policy, that I needed to add Bittornado to it. So in Bittornado, I selected the acceptable ports as 10000-10010 (randomized), and then in Firestarter for the outbound policy I allowed those same ports.The inbound traffic policy has no rules. All traffic is permitted and I have a direct connection to the Internet (no NAT). I do not understand why, if I have selected the permissible outbound ports in Firestarter, and also selected those same ports in Bittornado, why connections between my IP and the tracker are blocked?

I'm trying to connect to the www.freeopenvpn.com vpn service from my ubuntu 10.04 netbook edition. Installed the parts based on the instruction of the website, then the connection successful (lock icon on the connection area) but.....
the traffic does not go through, ping rejects with some "buffer error", network monitor does not show any data flow on the lan card. after the connection. Was trying it from commandline, and from gui as well. Same result. Can't even navigate to the service start page.
I do not have firewall, using the linksys built in firewall in my router. The same (dual boot) machine and router let the same vpn work under win XP, so the hardware is fine.
I suspect that it is a routing problem. (using dhcp from the modem-router)
Found that the vpn module installed the virtual tun0 interface and set up the routing table automatically.
Code:
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
173.192.86.142 192.168.1.1 255.255.255.255 UGH 0 0 0 eth0
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0

So I have two ssh servers I connect to regularly that do not use the standard port 22, so I use the "-p" flag to connect to them. This works flawlessly EVERYWHERE except on my girlfriend's work network. When I am on that network (same laptop), I can ssh into servers which use port 22, but not the other servers on this alternate port.Is there any way OTHER than ssh'ing into a machine I can access and then ssh'ing again from there to my destination (which, by the way, does work)? I want to make a direct connection for speed and security reasons.

I am still trying to run my Write It Now4 under Wine. The first time I couldn't figure out how to do it and then I changed the permissions to give myself Execute permission.This allowed me to install it under wine.When I went to open it, I was given the message again that it was blocked by Ubuntu. How do I unblock it. I have the rights to use this program but the people upstairs seem to know better. this is why I am trying to leave Windows. I don't like my computer telling me that I cannot do something I know I am allowed to do because someone somewhere decided it was not good for me.

I've setup the Uncomplicated Firewall (UFW) on Ubuntu 10.04 LTS and blocked an IP address. UFW status shows that the firewall is active and the IP in question is denied. The issue is that I'm seeing the blocked IP address in my Apache logs.

In my Ubuntu 9.04 installation, just a few days ago, I lost my usage of the internet. I still had internet access. Firstly though, there was a problem with the router, so I tried a friend's router (both Netgear DG834) and the friend's one worked. But in Ubuntu, I could not access any web pages or email. Skype works.
I tried using my netbook and that could access web pages okay. So then I booted my main PC into the old installation that I kept there of Ubuntu 8.04, which I am using now. And in this the internet works just fine, I can access websites and download and send email.
But in Ubuntu 9.04, it seems like something is blocking my access. I do not recall installing anything new, although something may have been updated recently. I can see the DNS servers from Ubuntu 9.04 and it gets an IP address from the router. What is the likely cause of the Internet being blocked for websites and email (but not Skype)?

I have kubuntu running. I have tried updating to KDE 4.5 Beta using the KPackageKit and i now get 118 blocked packages which i cannot install. I used the CLI and typed apt-get update and apt-get upgrade and this did not fix the problem. Is there anyway to find out why those packages are blocked?

I just upgraded to 10.10 (everything was working fine in 10.04). I have .jar files that in 10.04 would execute with OpenJDK. Now I get an error message, telling me that it is blocked:
"The file '[path]' is not marked as executable. If this was downloaded or copied from an untrusted source, it may be dangerous to run. For more details, read about the executable bit."
I try to set it as executable like it was before, and it's a no go. My checkmark takes then quickly disappears before my eyes.

I recently installed the XRDP server on my desktop edition of Ubuntu v10.04 following the simple instructions available here. I did this on two computers. One computer has Firestarter installed while the other does not.
When I use Windows to connect to the Ubuntu box without Firestarter, everything works just fine. However, when I try to connect to the one running Firestarter, I get a pop up showing an error message (see the attached file).
I checked the incoming rules in Firestarter and I don't see a way to add RDP sessions to the list of exceptions. I also tried adding my IP address in the host section but this too didn't help the situation.

I am using Ubuntu 10,04 with a gnome interface on an ASUS K70IJ. It all works well, just the internet connection is sometimes blocked or very slow. I have tried it on several places (offices, hot spot, friends) with wireless lan and ethernet. I thought it might be a problem with the pilot for the internet connection. Can anybody tell me where I could find such a pilot and how I do to install it?

I run ubuntu on home pc and am very happy with it. I use internet to surf and to see my email on gmail.com etc. What commands should I give to setup ufw firewall so that only this much is allowed? Also, where can I see if some other connections have been blocked?

I tried running Ubuntu Linux 9.10 on my computer directly from the CD, without installing, and when it had finished loading neither the keyboard nor the mouse would work. I got a message saying that restricted drivers had been blocked. I can't press what I think to be the unblock command because both the keyboard and mouse had been blocked.

I have installed MoBlock as instructed here: [URL]
After installation I created my own list file in /etc/blockcontrol/custom-blocklist.p2p and have the following uncommented at the bottom of /etc/blockcontrol/blocklists.list:
Code:
locallist /etc/blockcontrol/custom-blocklist.p2p
The list contains the following 2 entries:
Code:
Yahoo:98.137.149.56
Google:74.125.47.147
When I do:
[Code].....
Recently I just noticed that the locallist rules seem to have no effect. I will always get "destination port unreachable" even if the locallist entry in blocklists.list is commented out.
However, whenever I try to browse to that IP, even when blockcontrol is on, even by typing the IP into Konqueror (not the domain name), it lets me go there every time. How can I know that my other applications will not to do the same thing? How can I lock this down and test it empirically to be sure?

Sometime last week, my volume control disappeared. Upon investigating, I realized that the PulseAudio daemon was not running. When I tried to start it (both by command line and by graphical interface), it errored and refused to start. It is my impression that some other program is using the sound card, but I have been unable to find anything. I've removed all of my local media program configuration files, but nothing seemed to change.
1) finding the program that is locking the sound card?

I can't seem to establish a conncction to my site (that I'm hosting in the same computer as the gFTP client- running Lucid Lynx desktop as a server). My site is 'out there', with a domain etc. and also I work on it with localhost. I wanted to use ftp as Joomla has a 'ftp layer' for files permissions etc. But it keeps saying that I can't connect, or the connection 'was reset by a peer' whatever that means. For 'hostname' I use site.com (site is my site's name) and even tried the whole thing like http://www.site.com (I clicke on 'connect to remote, and enter that in the url). or just put it where 'host' goes (when I'm not using localhost) For user name and pass, I just enter what I usually put to access the administrator's back panel in joomla, but maybe I am supposed to use what I use to log on to ubuntu when I start my computer? note sure. Anyway I used a telnet command in the terminal and found that port 21 was blocked. MY isp says they don't block any ports so I don't know. I was able to do this last year so I don't know what is so hard about this lol In the router, I have 'ftp 21 to 21 and ip address 192.168.1.100 (ip is the same for http which is working as I have my site up) now it seems to be open as I used a command at the terminal (found from google). It's open but my ftp still can't connect to my server either localhost or to my site. there is no firewall blocking it and I think my router is set right.
