Ubuntu Servers :: Ssh Doesn't Work From Internet
May 2, 2010
I can't connect to my ssh-server (on ubuntu 10.04) from any external address. The error in putty is "connection timed out". From my internal network, everything works fine, even if I select my external IP address and port in putty as the destination.
This is what I have done so far:
installed open ssh with the ubuntu server 10.04 cd
set up port forwarding (11041) in my router (seems to work ok, port is open according to "shields up")
configured ssh to use port 11041 in /etc/ssh/sshd_config
changed tcp and udp ssh port in /etc/services to 11041
enabled UFW and did sudo ufw allow ssh

Hello.
I've openSUSE 11.2, 64-bit version, with GNOME desktop.
My hardware is a Conceptronic c150ru.
Well, I configured it with Ndiswrapper (http://en.opensuse.org/Ndiswrapper_howto), and I hadn't problems.
Then, I tried to enable Internet with the terminal. Firstly, I wrote iwconfig wlan0 mode managed. Well.
Secondly, I wrote iwconfig wlan0 essid (my essid). Well.
Then, I wrote iwconfig wlan0 key (my key wep). An error message appears. How can I write my key wep?

I just upgraded from 9.04 to 9.10. When I restarted, I admired the new login menu, then went to Firefox. I noticed that my wireless didn't work (it did in 9.04) Thinking I'd just need to reinstall the drivers, I plugged in the computer to a working Ethernet outlet with a working cord. I noticed that Ubuntu didn't tell me that Auto eth0 was connected. It didn't tell me anything. And then I went to Google and realized that the wired connection didn't work either. Then I came here on an iPod Touch and you know the rest.
Edit: And other devices work too on the network.

I have a desktop pc with xubuntu 9.10 32bit installed. I don't have direct access to this machine, but they told me that internet is not working (firefox, synaptic,etc...), but only skype works! If they reboot on windows, everything works well, so it's not a matter of connection or dns.It's very important because they work with that computer. How can i solve the problem? and what could be the cause of this strange anomaly

I've just upgraded to Ubuntu 11.04. Everything worked fine, until I rebooted. Now I can not connect to my home wireless internet, so I can't re-enable third party software sources. I am currently using a different computer, so I know that our internet works. I checked the wireless switch on my laptop, and it says that wireless is enabled. I've rebooted, and it still doesn't work. I tried our wired internet, and that didn't work either (although I'm not sure if our wired internet works; we haven't used it in a few years)

I have just dual booted my pc to run windows 7(64 bit) and ubuntu 9.10 (64 bit). This is my FIRST time using ubunutu and i have spent the whole day trying to get my internet working but with no success. I have come so close to giving up on ubuntu but for some reason i just cant let go! When i type in ifconfig in the terminal i can see that i have an ip address assigned and i can ping my router. My motherboard came with linux drivers and i tried installing the LAN drivers with the included instructions i have got no where. I did find out that the file name in the instructions was wrong and the actual name is r8168-8.012.00. Here are the instructions-

My wireless adapter connects to my WPA2 network perfectly, but when I run firefox it says it can't load the webpage, no matter what page I go to. Also, downloading new software doesn't work either. Any ideas please?

I have a WUSB54GC v.1 wireless USB adapter which I use to connect to my home network. For some reason, over time my reception has been getting worse. I'm not sure if this is due to the router or the adapter. In addition, when the signal strength dips below 50%, I can no longer receive email or browse the web. This is only a problem with Ubuntu - when I had WinXP installed, I could access the internet mostly regardless of the signal strength.
I started a year ago with the adapter plugged directly into the computer. After a while I found it necessary to use an extension cord to place the adapter outside my room, closer to the router. A while later it was time for another extension cord, and now my reception has gotten worse again, but I can't extend it any further.

I am running the latest ubuntu and I am having trouble getting networking sorted. I have 2 networks, one wired (eth0) and one wireless (wlan0). I connect to the internet using wireless. The problem is that I can only successfully connect to the internet if I disconnect from eth0. I have hit this problem with Windows machines and the solution was to adjust the "interface metric" in "Advanced TCP/IP Settings" so that the wireless was the preferred connection. How can I achieve something similar in Ubuntu?

I'm really new with Ubuntu and have the following problem:I installed successfully sun-java6-jdk using apt-get install sun-java6-jdk Then set up the JAVA_HOME environment variable to "/usr/lib/jvm/java-6-sun-1.6.0.20"
And then installed successfully tomcat6 using apt-get install tomcat6 apt-get install tomcat6-admin tomcat6-examples tomcat6-docs Everything seem to be right, when I try the browser with http://localhost:8080 return a webpage with "It works !" and other text
But, if I try http://localhost:8080/manager/html then returns 404 error, the error is something like "The required resource (manager/html) is not available" (that is my translation from the spanish text "El recurso requerido (/manager/html) no est disponible")

I recently installed vsftpd on my system and it was running fine for my system users. Now I wanted to add virtual users so I googled it, I found this tutorial: [URL]
I did what they've been saying over there but when I restarted the vsftpd I couldn't login with the virtual user and also not with the system user anymore. This is the error ( with the system user who could login before ):
Code:

Last night I was able to set up my server so that I can just connect vnc. I even was able to be connected at the log on screen so I could select which user I wanted to log in at. For some reason today, I have to have the monitor plugged in all the until the logon screen comes up before vnc will connect. Once the logon screen is up, I then can connect via vnc & select which user I want to logon as. It's odd because it worked last nigh, but today - Nope nada, it doesn't work & I can't explain why. I did clean up - Removing some applications I don't need on my server. (I'm hoping that isn't the problem) It's odd as well because I don't have to be logged on as a user to connect via vnc, I just have to wait until the logon screen is available...Then I can unplugged the monitor & logon.

I am developing/testing a PHP app on my netbook. For some reason apache/php are returning nothing but a "500 internal server error" response when there is a problem with my php script. For example, if there is a semicolon or closing brace missing, it should cause the script to die with a hint about which line caused the script to stop working. Instead it displays nothing but a "500 internal server error" message.

I'm trying to put two identical disks in Raid 1 for a homeserver. I got Ubuntu 11.04 server 32 bits on a USB stick. Installated till partition menu. Now I get the question how I want to partition my disks. I choose manual, and two times entire disk, one for both. It looks like this:
(iPhone quality)
I go to configure software Raid, and select Raid 1, 2 active disks, 0 spare disks, and get this:
I can't choose the other 2TB partition. I think I have to configure Raid three times, one for each partition. Not?
I click the missing 2TB partition, and get this:
But I think there's no RAID device at all, I see this again when I go to Configure Software Raid, en try to delete a RAID device:
How do I get Disk 1 and Disk 2 together in Raid 1? [URL]

I recently installed Fedora 15 x86_64 on my new AMD Machine and I'm quite pleased with things thus far.Here's where my problem comes. I mainly bought that machine to help me with Development. More specifically, Virtual Machines for testing purposes. I have installed Fedora 15 x86_64 as a qemu-kvm Virtual Machine and it's working.. for the most part. I am having a whole lot of trouble getting it to connect to the Internet.
My guess is the only way I'm going to reliably do that is to setup a Bridge. Yes/no? However, in order to setup a Bridge I need to disable NetworkManager and that where the fun happens. It completely disables my network connection. I'm probably missing something small, but I can't figure out what I'm missing. I've double checked my ifcfg-em1 multiple times(I've been trying for ~24 hours so far) and all the settings are as they should be.
I've turned NetworkManager off and stopped it(chkconfig and service) and turned network on(chkconfig and service). Theoretically I should simply need to turn off NM and turn on network and things should be fine. no?
Well, aside from adding:
ONBOOT=yes
NM_CONTROLED=no
to ifcfg-em1.

I installed apache on my local machine to test my sites. I have one problem:I created a new site configuration in /etc/apache2/sites-available and enabled it. The problem is that cgi is not working, it just prints the content of the files. (The default location for cgi, /usr/lib/cgi-bin works without problem.)Here is the content of the site configuration file:

I recently moved from Ubuntu Desktop to Ubuntu Server. I have a Dell D600 acting as a three prong firewall. I use a Netgear FA120 USB NIC for the third prong. After converting to Server, the NIC detects as Eth1. I'm able to configure an IP, but the NIC never sends or receives packets. The same NIC works great in Ubuntu Desktop. Dmesg never shows the NIC being ready.
