OpenSUSE Network :: Xen NAT Setup In 11.2 - No Basic Connectivity?

Feb 21, 2010

I am experimenting with Xen with the standard kernel (kernel-xen package) and utilities. I already got bridged setup to work with a single domU, but found out that because of my wireless card I cannot expect bridging to work when connected wirelessly. Now I am trying a NAT setup but I cannot seem to get any network connection from the domU to the dom0 and viceversa. Comparing the network devices and routing tables of others, I cannot see any problem.

The domU runs with IP 10.0.0.1 and the dom0 has a vif with IP 10.0.0.128 with a default gateway of 10.0.0.254. Pinging from the domU to the dom0 and viceversa does not show any traffic at all when I use tcpdump to monitor eth0 in the domU or the vif interface in dom0. It seems that basic connectivity of the vif interface and eth0 in the domU does not work. Any tips on how to debug this problem?

Ubuntu :: Teamspeak 3 Server Connectivity - Unable To Get Network Setup Correctly To Allow People To Connect Externally From My LAN?

Jan 21, 2011

I have Ubuntu 10.04 x86 installed, trying to get teamspeak 3 beta30.I have followed this guide: http://robert.penz.name/296/howto-in...u-10-04-lucid/

And can not get my network setup correctly to allow people to connect externally from my LAN. I have forwarded every relevant port I could find to the computer hosting TS, I forwarded them first as their respective protocols, and then as the combined UDP/TCP. I tried Forwarding single port numbers, and then port ranges.I have also tried uninstalling selinux.I have tried connecting directly to my cable modem with the server.I had this working perfectly three months ago with all the same software, using the same guide I listed above.The only thing I can imagine has changed is my operating system itself with system updates.

My network looks like:

Comcast cable modem--->Netgear WNR3500L Router----->Ubuntu 10.04 x86 desktop edition

what else I could possibly check? I can connect to and manage the TS server fine using localhost:9987 or 192.168.1.x:9987, it just wont allow any connections from outside the network.

OpenSUSE Network :: Create Network Bridge / Device Hooked Up Via Ethernet Had No Internet Connectivity?

Feb 25, 2011

I'm on opensuse 11.4 (11.3 won't work with my monitor).

My computer gets internet through wireless and I want to share that internet through its ethernet port. So far I've tried using Knetworkmanager to create a network bridge between my wireless and wired connections. I created a new wired connection and shared it using the ip address settings. I was able to get both connections active, but the device hooked up via ethernet had no internet connectivity.

I also tried this command:
echo 1 > /proc/sys/net/ipv4/ip_forward

but another test resulted in the same fashion (no internet on wired). I believe anything I add to /proc should have an immediate effect, correct?

OpenSUSE Network :: 11.3 - No Network Connectivity - Audio To Work On Skype

Oct 16, 2010

I had Kubuntu 64-bit installed and decided to try OpenSUSE instead as I was having problems getting the audio to work on Skype. After installing OpenSUSE 11.3 (64-bit), I do not have network connectivity (Ethernet or Wireless)? Neither adapter can be detected? I thought the install would be fairly straightforward as Kubuntu 64-bit detected all the hardware.

OpenSUSE Network :: WiFi Internet Works Fine But Limited Connectivity Elsewhere?

Feb 22, 2010

I'm using 11.2 with KDE.

I can connect to the Internet on my WLAN just fine (using Opera) and can dload torrent files (using the same).

However, I have had trouble accessing some community repositories in the past, cannot synchronise with an NTP server (annoying since my battery is low and time and date are reset most reboots) and cannot use the lyrics function or Wikipedia function in Amarok. Nor can I connect to the net using Firefox (though conqueror works just fine...) I cannot download torrents on KTorrent either.

It seems that there is some sort of 'permission'/connectivity issue.

OpenSUSE Network :: 11.2 Xen Bridged Networking - Setup Multiple DomU Through The Default Bridge Setup

Feb 4, 2010

Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?

General :: Trying To Test PHP Connectivity To Postgresql 8.3.9 Setup

Aug 4, 2010

I'm learning via baptism by fire method here, and need to test PHP connectivity to a local postgresql 8.3.9 setup. (CentOS 5.5 x86_64). I have got PHP and Postgres both working; I can pull up a test PHP page via web browser, and I can login to postgres via the command line. What I can't figure out is how to test PHP connectivity to the local DB.

I found this test script:
Code:
<?php
$conn = pg_connect ('dbname=template1');
?>

Which I've named, testdb.php - when I run ./testdb.php from the CLI though, I get:
Code:
./testdb.php: line 2: ?php: No such file or directory
./testdb.php: line 3: syntax error near unexpected token '"dbname=template1"'
./testdb.php: line 3: `$database=pg_connect ("dbname=template1");'

I've seen a LOT of pages describing the internal code of the PHP file, but as a newb to this, I don't know how to execute this test. I've ran chmod 755 against the file to verify permissions, but this didnt effect the results. I've also done a "chmod +x testdb.php"
Code:
PHP 5.1.6 (cli) (built: Mar 31 2010 02:39:17)

I realized I wasn't doing this:
Code:
php testdb.php
but when I do, I get this error message now:
"PHP Fatal error: Call to undefined function pg_connect() in /var/www/html/testdb.php on line 3"

Debian :: How To Use IPtables - Basic Firewall Setup

May 16, 2010

Recently I have been working on iptables and trying to understand how to use it. Here's a little script I have written to setup a basic firewall for myself:

Code:
#!/bin/bash
if [ `id -u` -ne 0 ]; then
echo "You need root privilege"
exit 1
fi

PROG=/sbin/iptables
$PROG -F
function sethttp {
echo "Opening http port..."
$PROG -A INPUT -p tcp --dport 80 -j ACCEPT
}

function sethttps {
echo "Opening https port..."
$PROG -A INPUT -p tcp --dport 443 -j ACCEPT
}

function settorrent {
echo "Opening torrent port..."
$PROG -A INPUT -p tcp --dport 52413 -j ACCEPT
}

while getopts "hst" option; do
case "$option" in
h) sethttp;;
s) sethttps;;
t) settorrent;;
*) echo "DOH!"
esac
done

$PROG -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
$PROG -A OUTPUT -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT
$PROG -A INPUT -i lo -j ACCEPT
$PROG -A OUTPUT -o lo -j ACCEPT
$PROG -A INPUT -j DROP
$PROG -A FORWARD -j REJECT
echo "Done setting up the firewall! Enjoy :)"
exit 0

OK, this can take 3 arguments that open ports 80, 443 and 52413. And at the end, some default rules are applied. But here's the thing I don't understand:
if I don't give the argument for port 80, I can still view web pages... and also, when I remove the line:

Code:
$PROG -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

Whether I say it to open port 80 or not, I can't view any web pages.

Debian :: 6.0.2.1 Virtualbox Setup - No Internet Connectivity By Default?

Jul 9, 2011

I'm coming from CentOS background and it's first time using Debian and currently stuck with setting up a working Virtualbox Debian Guest installation

Problem 1: no internet connectivity by default, but internet works fine from within the virtualbox Debian Guest OS if i use debian's internet browser

Problem 2: only internal 10.0.2.15 ip works (NAT) while my 2nd host only adaptor doesn't work out of the box

With CentOS all i needed to do it get it all working was when creating new guest on Virtualbox is setup 2 NICs, first one is NAT and second one is host-only adaptor. After installation, i can connect to internet and also from host OS connect to guest CentOS via 192.168.56.101 ip. But with Debian 6.0.2.1 64bit i defined both NAT and host-only adaptors, and out the box, only 10.0.2.15 is defined.

Default /etc/network/interfaces

OpenSUSE Network :: Wireless Card Realtek 8187 Connectivity - (Firefox) "the Server Can't Be Found"

Dec 3, 2009

I have a Toshiba Satellite L305-SP6944C, Pentium Dual Core 2.16, 2GB RAM, 160GB hard drive, DVD-RAM UJ880AS, display 15.6 TFT widescreen, ethernet Realtek RTL8101E/RTL8102E PCI Express, WLAN Realtek RLT8187, Opensuse 11.2 and KDE 4.3.1. Installation was OK and finally the wireless card is working... but I don't have conectivity bacause in the browser (Firefox) appears a message saying "the server can't be found"

I follow the howto write by Swerdna. With ndiswrapper I install the XP driver for RLT8187, KnetworkManager is in charge of connections showing both eth0 and wlan0, the wireless sign of router Dlink DIR-280 is OK, in the dialog box of network connection I put the mac address of the wlan card but I think that is not the problem.

Other thing that I missed is that I don't find boot.ini at any directory to add modprobe ndiswrapper in the boot sequence, in etc/init.d/ appears a "boot" file, is this file that I have to change to modprobe ndiswrapper??

OpenSUSE Network :: Setup As A Network Boot Server To Install Solaris 10 On A Sun Ultra 10 Client?

Does anyone know if it's available, if I could use the suse 9.2 version, or any alternative?

Ubuntu Servers :: LAN Setup - Basic File And Printer Sharing?

May 31, 2010

I am setting up a server for an office with about 4 computers and one remote computer at a home office. I would like the server to back up a selected group of folders on all of the computers as well as share some printers between them all as well. If all of the other computers are windows computers will Ubuntu work for something like this? I would also like to host a website and e-mail server as well if the server is not loaded down too much. I know I can get windows server to work, but I would like to use something else if possible.

Ubuntu Networking :: What Are The First Basic Steps To Setup A Wireless Connection

Aug 7, 2010

I have a computer with both wire and wireless connections. Wired connection works fine, but I would also setup the wireless connection.(I also have a dual boot on this cumputer with WinXP where both wire and wireless connections works fine. So, wire and wireless configuration of the actual router is not an issue here.)

At this point I just want to know the main/overview basic steps of setting-up the wireless connection on the computer. Also if you could suggest any links to guidelines for these steps. I have been thinking about something simple like this, but I might have missed a lotInvestigate if Ubuntu finds the wifi-hardware - the installed wifi card.Investigate if Ubuntu have an installed driver for this wifi-card.Configure the Wireless Network connection, like SSID.Unplug wire connection and reboot.

I'd like to have a set up where my Ethernet card has a static IP set up but my WiFi card doesn't.Currently I have a profile for this set up in Network Manager, however on boot up and every time I replug the cable Network Manager chooses the default "auto eth1" profile. I manually have tochoose my own profile for the Ethernet card every time. How can I make it default??I know the workaround would be to use ifup but then I lose the ability to quickly change access points for my WiFi card so that's not a solution for me

CentOS 5 Networking :: Static Ip - No Network Connectivity

Oct 27, 2009

I'm having strange difficulties in setting a static ip for my CentOS 5.4 installation. If I use DHCP everything is fine, but with a static ip I have no network connectivity. I have done this many times with RedHat/Fedora/Ubuntu etc. with no problems and now I have no idea what I'm missing or doing wrong. I have tried to set ip as 192.168.1.20 (anything below .100 will do). GW is 192.168.1.1 and NM is 255.255.255.0. This is all I have had to use with other distros, but now when I set these I cannot even access my routers admin page or ping it (192.168.1.1). (I just did this with Vista on my other machine and all worked fine).
