I ran an update on ubuntu server today, and after a long install process, it spat out an error, telling me to run "sudo dpkg --configure -a". After I ran that command, I was no longer able to access my website or forum. I could really use some help with this one, I've tried so many things including disabling shorewall, restarting apache, so many things...
View 9 RepliesI use Fedora 14 and Firefox as my web browser. I use Astrill VPN service. I have the following persistent problem: I start my computer. Astrill is not set to start on boot. I start Firefox. Firefox can not connect to anything, it says 'proxy server refusing connections'. I go to Edit>Preferences>Advanced>Network>Settings I click the radio button 'no proxy'. The problem remains. I am completely unable to connect to the net. Even on reboot, I cannot connect. On reboot, Firefox is set to use a proxy, although it was not on shutdown. Some init script is setting this. My normal connection is often faster than through Astrill, so I only really need to use it when I want to get at a website that is blocked by the govt here in China.
where Firefox is being told to use a proxy, and how to reset it to not use a proxy, assuming Astrill is not active. There must be something left in a .conf file somewhere which is overriding the settings in Edit>Preferences. Because, if I set it now to 'no proxy', I cannot connect to the net.
So Im newish to computing, and new to anything network/linux related.Situation: yesterday I installed Privoxy and it was working great (verified via Privoxy.org). Starting today while at a coffee shop i go the error "the proxy server is refusing connections". All of my settings are what they were yesterday and the default:
Code:
$ privoxy --version
Privoxy version 3.0.15 (http://www.privoxy.org/)
[code]...
When ever I try to sftp or even ssh into my server I get connection refused.
I have the port forwarded in my router.
What am I missing?
Also I have installed Ngnix so what do I need to do for it to work?
Since I cannot upgrade Adblock Plus anymore because iceweasel is too out of date for the new versions, I am trying to give privoxy a try. I am following the howto Block Ads & Fast Caching w/Privoxy +Squid without success. I am always receiving the error:The proxy server is refusing connections Iceweasel is configured to use a proxy server that is refusing connections.Check the proxy settings to make sure that they are correct.
I added these lines to /etc/privoxy/config
enable-remote-toggle 1
enable-edit-actions 1
permit-access 127.0.0.1
Moreover, I have edited the /etc/hosts file to block urls providing adverts and anything I wanted rejected.
The ssh server is running Xubuntu 9.04. It was working before. Then I tried SSHing today and it gave me a connection refused. The computers I've tried SSHing from were running Ubuntu Netbook Remix 10.04, MacOS, and Solaris 10. None of them would connect. The ssh server is running the latest version of openssh-server (according to apt-get install). I'm assuming something in /etc/ssh/ got changed but I'm not sure.

View 1 Replies View RelatedI'm running VBOX OSE and wanted to access files on my native machine (ubuntu 9.10) from my virtual machine (Windows XP professional)
Now, I can ping the native host from the XP box, but can't access the share.
I have tried re-sharing the directory but it won't work.
Another interesting aspect is that I can't access the VBOX either. It gives me the error:
"Error: Failed to retrieve share list from server Please select another viewer and try again."
Up until this morning it worked just fine.
Unfortunately I didn't pay attention which software was updated during the process.

there seems to be a problem that has arisen with my beloved netbook (acer one 10.4")running Ubuntu Netbook. the mouse generally works fine (both menovering and clicking) while using the desktop, but as soon as an application is opened you are unable to click on any of the options within the application (buttons, etc). i have tested this over and over, and what seems to be the problem is that the pointer ignores the application and will always click the desktop.
i have used several diffrent mouses (both usb and trackpad) but the problem remains. i assume this means there it is a software fault. if anyone has ANY suggestions, advice, etc. feel free to post. would like this to be fixed asap!
Is it fair to say that connLimit and hashlimit are very similiar on Linux i.e. while hashlimit caters to limits for groups of ports, they both set the connection rate limit per host? How in IPTables, do I configure a policy that limits connections on a port that encapsulates the total sum of all connections from all hosts? i.e. I do not want to allow more than 6000conn/minute for port range that is the sum of all connecting hosts?

I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.
View 5 Replies View RelatedBasically it looks like someone is flooding the UDP port for our server, which is running a game (Halo PC) through wine on Linux.I've tried "netstat -aun" but only get 0.0.0.0.'s as the IP address. there's anything I can install to log connections or any command I can run. Specifically they need to be UDP on port 2302 and port 2304- but since these Halo servers are the only thing running on this server, logging all connections would equally suffice.

View 1 Replies View RelatedI'm curious how I can use a Windows client with two separate accounts to connect, at the same time, to a SMB server hosting two shares. (Provided permissions and accounts are all in order)
Scenario:User1 is always logged onto a Windows client mapped to a Public share on a Linux SMB server.I need a way to keep User1 connected to the Public share and then when needed, allow User1 to provide User2's credentials to connect to a Restricted share.The only way I've been able to do this is to disconnect from the Public Share then reconnect to the Restricted share using User2's credentials. (This is the issue because I need to keep User1 connected to the Public share).Is this a limitation of SMB? Or am I missing a configuration? Please point me in the right direction
I'm having problems getting openssh server to accept connections in Ubuntu 10.04.Here's what I've done (twice): Installed Ubuntu 10.04 on USB drive with pendrive installer. This creates a default user "ubuntu" and you don't get the chance to choose a password for it. Started a keyring for network access and selected password. Works.Enabled VNC and selected password. Works fine with VNC client on local network. Logs in as "ubuntu" user and asks for the VNC password, then connects. Note: the client doesn't know the "ubuntu" user password, and neither do I! However, it works.Installed openssh client and server from Ubuntu s/w center.
$ ssh localhost OR $ ssh ubuntu@localhost try to connect, but asks for password, which I don't know (see step one, above) so, then I created a new user, with known password, logged in as new user in Ubuntu, works.however, $ ssh newuser@localhost still fails, even when correct password for <newuser> is supplied. Rejects the password three times, then gets the usual error about keys.I also tried connecting with an SSH terminal app from my iPad, again using <newuser>. It gets essentially the same error, "failure to authenticate".
All this is still on my own LAN, haven't gotten to going outside the router yet.What I want to do in the end is use VNC over SSH from a client on my iPad to talk securely to Ubuntu while I'm traveling.
There are two Fedora 12 systems which are now refusing to hibernate. The hibernation sequence seems to happen but then things hang indefinitely with a black screen and a blinking cursor, top left. I don't know where to start looking for clues; what do I look for in the logs, could someone please point me to a good hibernate/suspend troubleshooting guide?
One of the systems just recently got out of whack, for no apparent reason; it hibernated great for a couple of years, even as it went through upgrades from Fedora 9. The other stopped hibernating after its F9 -> F10 upgrade. This one lacks non-root hibernation permissions, but when I issue "/usr/sbin/pm-hibernate" as root, it goes through the motions and then hangs at black screen also.
For some time now I've been noticing the network activity light for my linux box blinking like mad on my router. After a little looking around for ways to see what connections my box has established, I found the following using lsof -i
Code:
bash 13839 root 1u IPv4 3118972 TCP shana:49148->Oslo.NO.EU.undernet.org:ircd (SYN_SENT)
bash 13839 root 2u IPv4 3118986 TCP shana:34323->161.53.178.240:distinct
[code]....
I know I'm not using IRC, and I have my sshd locked down fairly tight, requiring a key to log in, so obviously, it looks like there's something or somebody in Croatia (the origin of that IP address) connecting my system to undernet.org for some nefarious purpose. Looking at my processes, ID 13839 shows up as
Code:
13839 ? S 0:00 bash
Just 'bash', not '-bash' as
Code:
13426 pts/0 S 0:00 -bash
my session appears. Previously, this odd bash process was ID 2704, which seemed to imply that it had launched fairly soon after my system booted up which really makes me wonder. Oh, and yes, I did kill that 2704 process, and it returned as this 13839. 2704 also had those same IRC connections present in lsof.
I have a little file server, which also acts as a printer server and it has a web server implementation for Mapserver too.
Suddenly, nothing can connect.

I have a Compaq server, as per the title, and I wish to install Ubuntu Server onto it but ran aground when I found it got to trying to run the installer after the CD Boot menu, it just stopped there, waited 180 seconds (as per the error's details) and then locked up with the Caps Lock & Scroll Lock lights on the keyboard flashing.
Now I know it's not the server, as I have installed other OSes onto it in the past, including an older version of Ubuntu server (9.04), I did try and re-install the 9.04 version but the CD I had was too scratched up and got to a point in the installer (copying files) where it just failed cos it couldn't read the disc.

View 3 Replies View RelatedI have a ubuntu 10.04 dedicated server that I am having problems with. It intermittently cannot connect to any other servers outside its network.
Code:
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
^C
--- 8.8.8.8 ping statistics ---
8 packets transmitted, 0 received, 100% packet loss, time 7008ms
(I have tried a bunch of other ips too and none outside its network are pingable) I'm not sure if this is a problem with my server or a problem with the networking outside the server. I have been emailing my server provider and they keep on insisting the problem is with the server and that their network is working fine. Apparently all of their other servers work and they can login into the gateway and ping 8.8.8.8 from there. So they just want to reinstall the OS, but I thought I'd post here to see if anyone has any ideas.
Here is some info I have gained while troubleshooting: I haven't changed any settings at all on the server for months. I haven't done any updates for about a week. The strangest thing is that this is intermittent, there have been a few times in the last 24 hours where I have been able to ping 8.8.8.8 or other ips, but 98% of the time I can't. I have also tried rebooting the server, which had no effect. I can ping the gateway, and I can ping other servers on the same subnet. I can ssh onto the server from my home internet connection, and I can view webpages on apache, so incoming connections work.
My aim was to build a VERY simple smtp proxy under debian to handle mail from a port (51234) and forward it to the standard 25 port. I compile and install a "delegate" witch can handle easily that. It's working very well like that : delegated SERVER="smtp://anotherSmtpServer:25" -P51234
The strange thing is, it's working on my virtual test machine and on the dedicated server in local but I can't manage to use it trought internet. I test it like that. telnet [mySrv] 51234 Of course, no firewal, no deny host, no ined/xined, the service delegated is listening on the right port ... 2 clues : The port is answering trought internet with nmap as "51234/tcp open tcpwrapped" have a look at the tcpdump following :

Having some problems, which seems to be the norm for linux mint 9.
Background: I decided I wanted to try LibreOffice out so followed the instructions here: [URL] to install libreoffice.
After a week I found that LibreOffice doesn't actually have a spell checker or thesaurus even though it says it does. Decided I'd had enough so uninstalled it and auto removed the rest of its gumpf and attempted to install openoffice which actually worked, before. Problem is I can't, linux mint wont let me and keeps outputting random rubbish that makes no sense ie:
