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.

Software :: Setup A Radio Server With Icecast2 / Ices2 And Teamspeak

Jan 12, 2010

i'm trying to set up a radio server with icecast2, ices2 and teamspeak.

On my old server with a snd_hda soundcard it worked:

- people speak on a teamspeak2 channel
-- server with a teamspeak2 (aoss emulated) process "listen" people
--- ices2 capture sound from soundcard and stream with icecast2

Now i got no soundcard and i try to replicate my scenario using snd_dummy. Is it possible? I created my fake /dev/dsp used by teamspeak (no emulation) and seems to work, ices2 still don't start because "ALSA lib pcm_hw.c:1240_snd_pcm_hw_open) Invalid value for card" if i use hw:0,0 as device, "ALSA lib pcm.c:2144snd_pcm_open_noupdate) Unknown PCM /dev/dsp" if i use /dev/dsp. Missing PCM channel, as far as i understand. How can i solve? No "modprobe snd-dummy" parms seems to create PCM channel (as alsamixer shows) and ices2 won't start without.

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 and the dom0 has a vif with IP with a default gateway of 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 Networking :: OpenVPN Connection - Unable To Correctly Connect ?

Sep 7, 2010

I have setup an OpenVPN server on Ubuntu server. I am able to connect with Windows clients. I am, however, unable to correctly connect using Ubuntu.

If the router firewall is blocking the pings to keep the connection alive, then the connection initially does not work, but will work after the first timeout and reconnect. If the firewall does not block the pings then the initial connection attempt never times and therefore the connection does not work.

Attached is the readout from the client.

The first attempt gives error ERROR: Linux route add command failed: external program exited with error status: 7

Successive attempts work, they just time out every two minutes.

Networking :: Network Server (DHCP) - No Connectivity To Modem

May 4, 2010

Basically, I wanted to use the Bootp (PXE) protocol to boot a machine (my laptop) from my network instead of using USB/DVD boot medias to reinstall if need be. My router being a piece of crap, I couldn't setup the DHCP server to allow PXE packets. Confirmed from the manufacturer that it is not possible. Well for a $140 router, you would expect the opposite. Anyways, here I am with a small machine setup with Slack, no desktop environment (only CLI) and connected to my router (which I deactivated the DHCP) so the machine can act as a DHCP server. It works very well. However, I would like to install a few other utilities into that machine and for them to work, I need to put the machine between my cable modem and my router. Basically, here's the topology from outside):

Internet (ISP) --> Modem --> DHCP machine --> Router (no DHCP - acting as a switch) --> computers & printers

The problem is that I cannot connect to the modem from the computers on the network. Also I cannot access the internet (go on the WAN side) from the computers. From the computers (namely my laptop), I can ping the router, but cannot ping the interface where DHCP broadcast. Also I cannot ping the modem. From the router (using the web config page), I can ping the DHCP broadcast. From the DHCP machine, I can ping the modem. In the DHCP server, I setup the eth0 (the interface where the modem connect to) as a DHCP assigned IP so it can obtain the IP from the modem. The eth1 (the interface where DHCP broadcast) is static. All my machines obtains a IP from the DHCP machine without a hiccup.

Server :: Unable To Setup A NIS Server Setup On CentOS System

Jan 19, 2010

We are trying to set up a NIS server on a CentOS system. We need to have a NIS server which can provide NIS authentication to a couple of clients. We are practically new to all this stuff.

Just googled to find some ideas about installing ypserv and ypbind and portmapper. We did all that and also started them successfully. But now the clients are not able to join to the NIS domain . The error log states "YP_DOMAIN NOT BOUND".

I guess we have not entered the /etc/yp.conf, /etc/hosts files properly. Please let us know the detailed steps to setup a NIS server .

Also, please let us know what entries should go into the different /etc/<file_names>? What is meant by HOSTNAME in the /etc/hosts file?

Is there any other files which need to be changed? Are we missing any steps?

Also to add-on, while executing the ypinit command we faced the following error:

At this point, we have to construct a list of the hosts which will run NIS servers. localhost.localdomain is in the list of NIS server hosts. Please cont inue to add the names for the other hosts, one per line. When you are done with the list, type a <control D>. next host to add: localhost.localdomain next host to add:

The current list of NIS servers looks like this:

Is this correct? [y/n: y] y

OpenSUSE Network :: FreeNX For People Upgrading To 11.3?

Jul 18, 2010

Just incase anyone is suffering from the same problem as I was after upgrading to 11.3 that there was no such file or directory in /var/lib/nxserver/db/running/sessionID. I found the answer in another forum and thought i would post it here. Basically there is a change in the openssl library used to calculate the md5sum used by nx which stopped it from connecting.

at the end of /etc/nxserver/node.conf fixes the problem.

Fedora Networking :: Unable To Connect To Wireless Networks And Unable To Configure Network

Jul 27, 2010

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.

Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network

However, there is no Network option under System>Administration.

Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."

Networking :: Unable To Connect To Wi-Fi Network With Network Manage

Nov 21, 2008

I'm unable to connect to a particular home wireless network under Fedora 9, although I can connect to it using WinXP on the same machine. My Fedora installation is able to connect to my college's unsecured wireless network, so it's not a driver issue I think.It seems to be an authorisation issue, as I'll describe below, but there's one other thing that's bothering me. The SSID for the network I have problems with is for some reason not listed in Network Manager's drop-down list, nor is it in the output of iwlist wlan0 scan. But I'm pretty sure it's not a "hidden" network - I don't know exactly how those work, but I helped the owner of the wifi network in setting it up, and don't remember doing anything that would make it hidden. As far as I can remember, Windows found the network automatically without having to be told the SSID. What's the best way to confirm whether it's a hidden network or not?

Anyway, I try to connect by selecting connect to other wireless network in Network Manager, and entering the SSID. As far as I can tell from the error messages below, the machine does contact the network and attempt to connect, but I'm not authorising myself properly. That may be a completely wrong diagnosis, but hopefully someone can see from the below info whether it's correct or not.I'm not sure which option to use for "Wireless Security": at the time we set up the network, it gave us a Hex WEP key of 26 characters, which is 104 bits. But none of the options in Network Manager's list match that. Here are the options it has, and the error message I get with each one:None - if I select this, it fails to connect, with no error message.
WEP 128-bit passphrase - if I select this and attempt to use my 26-character WEP key, it brings up a new dialog, saying "Passwords or encryption keys are required to access the wireless network [SSID]." It has a drop-down box labelled "Wireless Security", but this time the only option is "None", and the connect button is disabled, I can only click cancel.
WEP 40/128-bit hex - as above.
WEP 40/128-bit ASCII - The connect button is disabled when I try to use the WEP key, as the string is too long. Despite the fact that it says 40/128-bit, it actually accepts 5 and 13-character strings (40 or 104-bit). Since I've got a 104-bit hex key, I tried converting it to ASCII, but it consists of mostly unprintable characters, so I'm not sure there's any way to actually enter it into the textfield. I might have done something wrong here, so I've put my code below to see if anyone can point out a mistake.
LEAP - requires a username, not applicable here I think. Windows doesn't need one, and we don't have one from when we set the network up.Dynamic WEP (802.1x) - requires username, private key and various other things, all N/A WPA & WPA2 Personal - Brings up a dialog with the same text as for "128-bit passphrase", but this time "WPA & WPA2 Personal" is the only option in the drop-down list, instead of "None". It asks for a password, so I just enter the hex key again - now it asks for the password for the Gnome Default Keyring, which I don't think I've ever set up. Don't know if I can go any further with that, but my understanding is that since we were given a WEP key when we set up the network, WPA will be N/A.WPA & WPA2 Enterprise - as Dynamic WEP. N/A.Hopefully that's enough info that someone can help diagnose the problem. Some of the behaviour of Network Manager described above doesn't make sense to me, and I'm wondering if it's buggy.

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??

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:
$conn = pg_connect ('dbname=template1');

Which I've named, testdb.php - when I run ./testdb.php from the CLI though, I get:
./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"
PHP 5.1.6 (cli) (built: Mar 31 2010 02:39:17)

I realized I wasn't doing this:
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"

Server :: Virtual Hosts On LAMP Not Going To Right Directory Externally?

Jul 16, 2011

I created LAMP server with a wordpress site. I created a sites-available file for the wordpress file pointing to the wordpress directory. Within my server it goes to the site properly. However I also made this server a DNS server, had another test pc use it as a DNS server and it only got the default apache page unless I added /wordpress to the url which makes it point to the directory within /var/www/ that it belongs, but then the wordpress links don't work and this is not what I want it to do anyway. I do not understand why it is working properly internally but not externally. It makes me think maybe the sites-available file is not allowing outside access appropriate permission to use it or something. Can somebody please point me in the right direction I have been working on this for weeks and I am starting to get really frustrated with it. Tell me what config files can help you figure out my issue. Also I eliminated the default index.html file so it wouldn't use it, then placed the index.php file from wordpress in /var/www/ root but in that configuration it doesn't load anything by default but will still work if you point to /wordpress. I believe I have to make some change to my apache2 configs to allow outside PCs to be pointed to the right root directory for the virtual host like is being done internally, I just don't know where to start.
