I have recently installed MATLAB on my computer, which I have access to licenses from the engineering department license server at my university.This means, that in order to run MATLAB I have to open two SSH connections first:ssh -q -n -x -L 1711:matlab-lmserv.eng.myuni.ac.uk:1711 usrname@gate.eng.myuni.ac.ukssh -q -n -x -L 20001:matlab-lmserv.eng.myuni.ac.uk:20001 usrname@gate.eng.myuni.ac.ukEach of these commands will prompt me for my department password.What I'd like to do is have a script which opens both these connections and then starts MATLAB, without any other input. How would that be done?
have a problem with my network-manager in ubuntu 10.10.when I dial one of my vpn connections, my other vpn connections be disabled and I can't use them!I tried to restart network-manager and gnome-panel, but it does't seem to solve this problem.
All connections on my computer start loading and then hang: it happens when running apt-get update (a few repositories load successfully and then it hangs at a random one) and when loading web pages with the browser (it says "Connecting...", then "Waiting for....", sometimes some part of the page loads, and then it hangs).
This happens both with my wired and my wireless connection. It does not happen on Windows on the same computer.
I'm having a bit of Internet trouble with a fresh install of Ubuntu Natty and I haven't been able to track down the problem. I have my desktop running over a wireless network, which connects without fail. Somewhat frequently, however, connections to particular websites will start timing out (google, facebook, stackoverflow, us ubuntu archive, etc.). I'm also having a strange issue where my home page [URL] is redirecting to [URL].
Initially I thought it might be an issue with Comcast DNS, so I updated the router to use OpenDns servers. When that didn't work I started to try accessing some of the problematic sites through my laptop (which is using the same router) and they all connect without problem. The issue seems to be with my Ubuntu install, but I'm not sure where to look.
EDIT After doing some further digging, this is starting to look like a DNS issue. My home page appears the resolve to an incorrect ip address when the redirect issue occurs. Still not sure how to track down the problem, however.
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.
Im trying to run synergy on startup. This works fine on the client, but it wont start automatically on the server. I put this line in an entry in startup applications:
I installed 8.04 on my EeePC 2005. I use the Windows dual boot option. The netbook's hard drive was factory set with two partitions c and d. Windows XP is on c; I put Ubuntu on d. In Windows, I have both wireless and ethernet (sp?) working fine.In Ubuntu, I have no wireless and no land line. The manual connection wizard pop-up shows no networks anywhere. How can I get Ubuntu connected? Would it be simpler to load another distro like Easy Peasy on top of Ubuntu? Or should I delete Ubuntu and start over? Or is there an easy fix for 8.04?
I've been trying to access the internet on my desktop running 10.4 x64 through my laptop running windows XP. The laptop has a wireless connection and I'm trying to use an ethernet cable to bridge the connections. I've hooked them both up, and under Network Connections in XP I selected my wireless connection and the 1394 connection and right-clicked to bridge, and it does. But ubuntu doesn't want to pick it up.
I did a clean install of Ubuntu 11.04 64bit and the start up time is abnormally slow. If I start up the computer and don't press anything, the start up time is 30 minutes but it usually doesn't start up at all. It just boots into a purple screen, no splash, then it sits there and the computer doesn't have any loading lights flashing.
I had a similar problem with 10.10, but I assumed it would go away when I did a clean install of 11.04.
I can't get a read out of what's going wrong because when I press Esc it doesn't display anything, though weirdly it can sometimes get the start up process moving. I have also found that pressing enter really fast can sometimes help and something that seems completely oxymoronic, if I press the power button while it's starting up that can make it work, but nothing works every time.
I have a mysql database and i use it with apache for my webpages. And I guess it dosen't start when the computer starts so I have to manually start it with "sudo /etc/init.d/mysql start" This returns fail so i went to '/var/run/mysqld/' and the folder was empty. I don't know if this is the problem or not. How can I fix this?
When I click on the network manager icon next to the date in the upper right corner of my screen, my network connections do not show up. I have added two DSL connections on my laptop (username & password) but it doesn't show up. Everyday I need to use
Code: sudo pppoeconf if I wish to connect to the internet.
Both these connections are added in the same way on my Desktop Computer and it shows up on the network manager. One of them is even the default which connects automatically on startup.
Because it's not working I assume network manager is not compatible with my laptop. Are there patches to install or other programs that can easily manage my internet connection?
Firestarter sometimes shows up to a dozen different ip connections for a single webpage that I open. This is for the first webpage I open, not after I have been browsing for awhile so they are not old connections that have not timed out. This just doesn't seem normal to me since other installs I have had of ubuntu have only shown one or two firefox connections at all times.
I am noticing really odd behaviour after upgrading from 8.10 to 9.10 (via 9.04). My server frequently becomes unreachable. I am using it as an application server, running Apache, JBoss and MySql. Once the server goes idle, all web connections time out. SSH also times out. Usually the server wakes up on second SSH attempt and then everything: Web, SSH etc seems to run fine.
This is a server machine with no GUI. Can anyone point me to power management or other such settings I can tune from commandline? I have disabled power management by adding kernel parameter acpi=off. I still have the problem. The first network connection after the machine has gone idle takes a long time. All later connections run pretty smoothly.
I've installed Samba on my Home Theater PC but none of my other computers can stay connected to it. Sometimes it drops connections right away, other times it takes several minutes.either way, a pc will never stay connected longer than 20 minutes.
I have the following OS's in my home OSX Snow Leopard Server 2003 Server 2008 Windows XP
I have a small business that I run Squid and Dansguardian on Ubuntu for network proxy filtering, among other things. This works great, but does not block SSL connections on Port 443, such as https proxies. I understand that this is because this type of configuration is a "transparent proxy".
Is there a way to set one up "non-transparent" and, would that filter https?
I cannot blanket block 443, because some sites need it.
I have read that one can re-compile Squid to work with SSL, but not being a super guru, not sure of the implications of doing that.
I need some suggestions on software. I would like to offer remote desktop support to some of our clients, but some of them are using ISP's that block incoming connections so, VNC is out of the question. I was wondering if there is something similar to logmein for ubuntu?
I have recently installed lucid 10.04, and I am having difficulty accessing my wireless. Following instructions to install the drivers for my wireless card, I always run into a problem when I need to configure my card. When I go to system-administration-network, there is no connections tab listed. I can only access General, DNS and hosts.
The server kicked me out because Dolphin opens many many connections wile browsing through the servers filesystem with dolphin. i have to wait several minutes to be able to upload files after the limit reached. i am using kubuntu 10.04
Did ragemaw ever get that missing connections tab? Mine is missing too and furthermore wireshark cannot set up on any interfaces, because it cannot find them.
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 checked all the logs in /var/log but couldn't see anything (I was hoping /var/log/auth.log would have it, just like it has ssh connections in there). I've got a machine that several people VNC into and I would like to keep track of things. Are there other VNC servers out there that keep logs? I could switch, but I went with krfb because it works perfectly for me and came already installed.
So I'm going to try out opendns as an internet filter. But I'm not doing it on a network/router, just on my local machine. Using ubuntu, I read that I need to select each connection and change the dns settings.Is there a way to generically add the dns settings so that if I connect to a new network I don't have to manually update it's settings?
I get a message on boot that I have too many connections. so I looked ate the dmesg file but I have no idea what is going on. My system is a i7-960 cpu on a saber tooth x58 asus motherboard, with 12 GB of DDR3 (4GB per channel) running the 64 bit version of maverick Ubuntu.
i am too new for linux..I installed Ubuntu 10.10 desktop edition from windows.When i am trying to configure network connections i am facing problems
Code: udo pppoeconf no working ethernet card could be found.If you do have an interface card which was not autodetected so far,you probably wish to load the driver manually using the modconf utility.Run modconf now? /usr/sbin/pppoeconf: 523: modconf: not found Ifconfig
I've been searching and searching trying to figure out how to get ubuntu to connect to ad-hoc connections and just can't figure it out. Can anyone help me out with this?I have the Droid 2 Global and I use "wifi tether" and it works for getting internet on windows and on my 360. But I just installed ubuntu and can not get it to connect.
I might be misunderstanding the log but it looks like UFW is blocking connections. I want to allow all incoming and outgoing. I guess what I'm saying is that the servers on my computer will open ports but all other ports should respond with closed just like a default Ubuntu install. Trying to use UFW to monitor connections without really doing any firewalling.
I want to set up my laptop to allow connections to certain users with passwords from anywhere over the internet via SSH but I'm unsure about how I would go about doing this. I only thought it would be the case of setting up the open-ssh server on the laptop then, using my external IP and PuTTY on another PC outside of the network, connect to the external IP through port 22 so I tried this and wait 3 or 4 minutes or so and it says the connection times out.
I have also configured my router to use port forwarding but this doesn't seem to help much either and I have LAMP setup to allow connections to external IP : 80. The only thing I am able to do is access the laptop through the local network by using its internal IP's like 127.198.0.1:22 or something. I was wondering if anybody knows if and could tell me how I would do this as I really want to be able to access my home computer/laptop from my work sometimes, especially if I have work at home which is not with me at work or something.
I know this is possible but I'm quite new to this type of thing and don't know what is going wrong. Have I missed something or do I need to change any .conf files or anything?
