• Configuring vlans on Cisco SG200 series switch with Ubuntu server

  - by nixnotwin

  I created a vlan on Ubuntu with vconfig tool with 21 as id and eth1 as the host port. I connected eth1 to one of the ports on the swtich (GE23) as all ports trunk by default. In the webgui I created a vlan named test with the id 21 and I made GE2 are port as an access port. In port to vlan mapping I selected vlan 21 and added it port GE2 by selecting untagged option. I have assigned 192.168.1.1/24 as the ip of eth1.21 on Ubuntu. If I connect another cleint pc to GE2 port with a ip of 192.168.1.2/24 I cannot ping the server ip (192.168.1.1/24). Ping from server to client also does not work. I inspected packets that are sent out eth1 on the server and I could see the vlan 21 tag. And I connect the other end of the cable to a different Linux pc and inspected the packets but no vlan tags can be seen. What could be preventing me from getting vlans working? Edit 1 screenshots:

• Ubuntu Server 10.04 Heavy Network Traffic causes disconnect

  - by K Vaughan

  I'm currently running a headless Ubuntu 10.04 server. Installed is the LAMP stack, Joomla, Virtualbox, phpvirtualbox, webmin and proFTP.. It resolves the IP address so I can access it remotely (either the apache2 webserver or the FTP) using DDClient. Any packages installed have been installed using apt-get. Webmin, although discouraged in Ubuntu Server, is used mostly to administer the webserver aspect. This issue also appeared when I was using Ubuntu Server 10.10. After periods of heavy network traffic, whether local or remote, the connect drops. I'm talking specifically about the transfer of files via FTP, SCP or Samba (the latter of which I seldom use). There is no response to ping or ssh. I can't FTP to the server nor can I load the website. There are times when the server has been on for a few days and everything runs fine because I haven't accessed it much, if at all (thus not much network traffic). I've gone through a few hardware changes although I don't believe this has cause the issue: this has been happening long before I made any changes. At first I thought it was my ISP-provided router blocking traffic because of some kind of misconfiguration (perhaps assuming it was some kind of DoS attack). I've changed routers and still found no success. I've checked syslog, dmesg and kern.log for warnings but have uncovered none. I've ran memtest via the GRUB2 menu at boot and once it turned up 4 errors. I ran again with individual sticks of RAM in various slots and everything turned up fine. I've looked through the BIOS settings and everything looks fine. I've tried unplugging unnecessary pieces of hardware (other internal hard drives, CD drives, floppy, PCI cards, etc). Any help or tips on how I can even begin to troubleshoot this would be very much appreciated. Please note that i've only started playing with servers as a hobby so my knowledge wouldn't be the most refined. I'm comfortable with command line and have the initiative to know how to look up something I can't do. Unfortunately I can't seem to find any issues like this. Additionally: If a solution can't be found some assistance to write a script that will cause the server to reboot automatically if, after x minutes, it gets no response to pinging somewhere like google. Admittedly that's not the cleanest solution should my internet end up going down but I can't think of what else to do.

• Internet connection sharing: Ubuntu 9.10 Server on Windows 7 and VMWare

  - by avesse

  I'm trying to get Internet Connection Sharing (ICS) working between my Windows 7 RTM host and a Ubuntu 9.10 Server running on VMWare Workstation 6.5, but I have not been able to get it right. Here's what I have done: Configured VMWare to use Host Only networking (I tried NAT as well). Enabled ICS on my host's network connection, allowing VMnet1. After enabling it, Windows informed me that its VMnet1 IP has changed to 192.168.137.1. So in VMWare's Virtual Network Editor I configured VMnet1: Subnet 192.168.137.0 Mask 255.255.255.0 I did the same for DHCP. For NAT i set 192.168.137.1 as Gateway. I cannot ping any sites or get access through apt-get/aptitude install/update, although domains do get resolved to IPs. I have also tried using a static IP in Ubuntu. I don't know if it makes a difference, but my external IP is locked to my host's MAC address.

• Windows Live Mail treating my Firefox as mobile device

  - by Mussnoon

  I started using Namoroka (firefox 3.6 nighly) yesterday and since then, windows live mail has been treating it like a mobile device. Same thing happens when I try with Minefield (firefox 4 nightly). I've tried loading the default page in Chromium and then pasting the URL to firefox. The sign in page shows alright then, but as soon as I sign in, the mobile inbox shows up again. I've tried clearing the cache+history+cookies everything but nothing's working. Anyone know of a solution?

• Can't get .htaccess to work

  I'm using Apache2 on Ubuntu Lucid Lynx. I have config set to use .htaccess like normal.

• Cloudstack virtual machines can't communicate with virtual routers when they are on different hosts

  - by Jorge Suárez de Lis

  I'm using Cloudstack 2.2.14 on a Ubuntu 10.04 set of hosts, and I have a problem on my setup. I have two hosts running. When a virtual router is created on host 1 and a virtual machine using that virtual router is created on host 2, or vice versa, I have no connectivity at all on the virtual machine. First of all, I have to setup the network manually on that virtual machine -usually DHCP is working, but not here-. Then, I can't ping to the virtual router from the virtual machine or vice versa. When both virtual router and virtual machine are created on the same host, everything works! Maybe those packages are being filtered somehow? I have no clue on how to proceed. Both hosts can communicate directly outside the virtualization.

• Ubuntu 10.04 LTS - good enough to jump on it?

  - by iconiK

  I'm currently planning to get a VPS from VPS.net for a PHP project. I personally haven't used CentOS (which is recommended all the time) and this is not a good time for me to start learning it, so I want to stick with Ubuntu, as that's the one I have experience with. Now there's the good ol' 8.04 LTS that's well supported, however, 10.04 LTS was released two days ago. I installed it on my laptop and it is pretty slick (doesn't matter for a server) and quick. But I am skeptical about it: Has anyone tried it in a production environment so far? How does it perform versus 8.04? Any serious bugs so far?

• Ubuntu 10.04 server delay responding to AJAX requests

  - by DanielAttard

  I manage a Ubuntu 10.04 server with a couple of domains hosted on it. As I continue to learn more about all these wonderful new (for me), one issue that I have begun to notice is the delay it sometimes takes for the server to respond to certain requests. As an example, when I view the timeline of events using firebug I can see that most of the time when I make a POST, the server responds in under 100ms. Sometimes, however, there is a substantial delay before the RESPONSE from the server. I can't seem to tell when the delay will happen and when it won't, however, when it happens the delay is always for about 4.5 seconds. The delay seems to happen about 30-40% of the time. Here is the section of apache2.conf dealing with logs: # # The following directives define some format nicknames for use with # a CustomLog directive (see below). # If you are behind a reverse proxy, you might want to change %h into %{X-Forwarded-For}i # LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%h %l %u %t \"%r\" %>s %O" common LogFormat "%{Referer}i -> %U" referer LogFormat "%{User-agent}i" agent I have no idea where to look to try and debug this problem or investigate further. Any suggestions?

• Antialias not working in ubuntu lucid lynx 10.04

  - by mac

  I have recently upgraded from karmic to lucid (plain ubuntu using gnome). Everything worked fine, but the characters now aren't anti-aliased any more, as you can appreciate from the screenshot: This is what I tried to fix the situation, unluckily without succeeding: Used the regular option pane from System-Preference-Appearance-Font (smoothing, hinting...) Edited the .fonts.conf file Disinstalling (and then re-installing) the mstcorefont package Changing the default Sans font to a font of my liking (e.g. Tahoma) from the abovementioned Appearance options My ubuntu installation is quite standard, with the typical add-ons one might wish for usability. I used the ubuntu start script to make a few tweaks. Thank you in advance for your help! :)

• Updating Dell PowerEdge firmware on Ubuntu?

  - by Shtééf

  The company I work for recently got hands on a batch of second hand PowerEdge SC1425 machines. We'd like to put these to good use. Our operating system of choice is Ubuntu Server 10.04 64-bit, which installs just peachy on this type of machine. Now I'd like to install the firmware updates from Dell, which are apparently marked as recommended. This includes the updates for the BIOS, the BMC, and possibly some other hardware. I find it incredibly difficult to locate the files on the Dell website, and install any of them on an Ubuntu system: I downloaded the file OM_6.2.0_SUU_A01.iso. I believe I've read that the SUU DVD should be able to update any recent PowerEdge. Is this correct? Is this the latest version? Besides the version number, does A01 have any meaning? Is this image bootable? (At the moment, I just nosed around with a loop device mount.) Running /bin/bash ./suu from the DVD, I get: # /bin/bash ./suu ./suu: line 262: ./java/linux/i386/bin/java: No such file or directory The file exists and is executable, though. But I cannot execute it directly from the shell either.

• Free Hosting control panel

  - by John Maxim

  I'm in the mid of researching for one of the best hosting control panels. The server I run is Ubuntu and I have some experience with ISPConfig 2 & 3. Since I haven't explored any others available, what are the recommended ones for an Ubuntu server? I asked because I find that there seems to be some disabling and modifications required for an Ubuntu server if I need to use ispconfig which causes the server to change its actual way of running. It's quite good though, but any more recommended ones ? Something more organic? which doesn't require much breaking and changing. I'm not asking for the simple one, I don't mind going extra mile to install a powerful one but just try sticking with most Ubuntu's conventions will be an ideal one for me. And of course, if there happens to be something that meets the requirement as mentioned "Ubuntu conventions" and also simple to install at the same time, that'd be a bonus. Thanks in advance.

• Ubuntu Newbie Needs Assistance!!

  - by Steve Greene

  New Ubuntu User Needs Help!- version 9.10 does not communicate with laptop Hello folks, Several days ago, I installed Ubuntu 9.10 onto my Acer Aspire 3100 laptop, running it alongside Widows Vista as a dual-bootable system. Creation of the Ubuntu boot CD went fine, and the installation onto my hard drive was flawless. Ubuntu opens and behaves as I would expect, except for one little problem. For reasons unknown to me, Ubuntu is not communicating with my laptop's networking hardware, and I have no internet connectivity, even when sitting directly under the wireless router at the local library (literally), which puts out a wickedly-fast signal that my Windows Vista OS auto-detects and immediately connects to. Up in the right side of the Ubuntu desktop, I click on the network icon and it does not show a wireless connection at all, even though I am only a few feet from the router. At home, where I use a dialup modem, I also see no means of getting online. My modem is an HDAUDIO Soft Data Fax Modem with Smart CP,manufactured by CXT (Conexant Systems Inc., file version 4.0.13.0, and the driver version is 7.58.0.0). I desparately wish to convert to Ubuntu. I used Mac for ten years, and then Windows for ten years. Now, after 20 years, I want to live out my days as an open-source Ubuntu fanatic. I am ready to give the old status quo the boot! I am an advanced computer user, but I am not a programmer. I seek a solution that is user-friendly for normal people, something equivalent to a driver that I can easily install or activate that will allow Ubuntu to see my hardware and get me connected. Can anyone help me over this hopefully-little glitch so that I can move on in total Ubuntu bliss? My processor is a Mobile AMD Sempron Processor 3500+ at 1.80 GHz, 1.50 GB RAM, and a 32-bit Operating System. I am running Windows Vista Home Basic, Service Pack 2. My current email is [email protected] if you have a workable solution that does not require programmer status to implement. Surely this must be a simple fix that I simply am overlooking, but being the new guy on the block, I have yet to be enlightened. Thanks for your help in coming up to speed!! Steve Wanna' be Ubuntu Fanatic "If you're not living on the edge, you're taking up too much space."

• What could cause a huge packet loss in Ubuntu 9.10, for both wired and wireless?

  - by xzenox

  I was previously using 9.04 fine (and in fact, I am posting this from my old 9.04 live cd). I tested the following install steps in a virtualbox vm prior to following the sames ones to upgrade my laptop: Download/burn ubuntu minimal cd (12mb one) Install ubuntu minimal sudo apt-get update sudo apt-get upgrade sudo apt-get ubuntu-desktop ubuntu-standard In the VM worked fine and I found myself with a working 9.10 ubuntu, network worked fine and I was able to test my backups and DropBox without a hitch (host was 9.04). When I followed the same steps on my laptop, everything worked up to after 9.10 being installed and working. As far as I can tell, everything besides eth0/wireless works. For some reason, I am unable to access the internet. Ping reports that over 99% of packets get lost (over an hour or so of pinging). This means for example that if I try hard enough, I can load a webpage but only at the cost of much patience... This happens both for a wired and wireless connection to my wrt310n (updated with latest firmware). At first I thought that it could be related to the ipv6 issues ppl have been experiencing however even after disabling ipv6 at the kernel level (through grub), I still get the issue. I do not think this is related to DNS issues or the likes since even when I ping my ISP's gateway IP, I have the same amount of packet loss. No DNS resolving should be required there. Access to my router works peachy with no packet loss there. I've tried different MTU values but to no avail. Note that this issue affects every web-enabled application: firefox, ping, synaptic, etc. The same hardware/router combo works with 9.04 but not with 9.10. In fact, when I did: sudo apt-get ubuntu-desktop ubuntu-standard after 9.10 minimal was installed, it downloaded over 400mb of packages without a hitch so my guess is that one of those packages either in ubuntu-desktop or ubuntu-standard is causing havok. Thoughts?

• Ubuntu issues when moving hard disk to new system

  - by Tim

  I'm working on a legacy project with a small single board computer running Ubuntu 10.04 on a compact flash card. I need to be able to save away a working image (via dd) and copy said image to other compact flash cards for use in other single board computers (with identical hardware) I'm able to copy the image to other flash cards and bootup on other systems no problem. But I'm seeing strange behavior. For instance, I can't use sudo on the new system (“sudo: must be setuid root”). I've gone down the path of trying to fix this, but have run into a slew of other issues. General question is: what do I need to be aware of when moving a hard disk containing Ubuntu (in my case a compact flash card) to another computer? I was hoping it would be seamless to Ubuntu since it's moving to a system with identical hardware. Is there something that needs to be done to make it "portable"?
