Jun 7, 2009

OpenSUSE Network :: Text Incomplete On Websites?

Sep 28, 2010

A good deal of text on web pages are missing; also, the links are usually coming up not as text but, rather, as lines. I've 11.3 installed.EDIT: Ignore the below -- it seems that the server was just slow, is all.(I would have queried this via the listserve, but <opensuse+subscribe@opensuse.org> is not recognized by the mail server.)

OpenSUSE Network :: Wireless Connection Can't Access Websites

Mar 7, 2010

I just installed Opensuse 11.2 dual-booting with Windows 7 on a laptop. I have the wireless set up and connected, but I can't seem to be able to connect to any websites or ping Google, etc.I'm kind of a Linux newbie, so I'd like to get some advise as to what I can check to get it working? (Windows 7 on the same machine is able to connect - I'm using it now)

- I've tried both automatic DHCP configuration and also setting the ip/dns server manually, no luck

OpenSUSE Network :: Connecting To Home Wireless In 11.3 - No Connection (websites Will Not Load)

Jan 22, 2011

I've just installed openSUSE 11.3 for the first time on a Dell E1505 notebook and am having problems connecting to my home wireless network. Using the Network Manager I've been able to find my home network and connect after entering the network password. After a minute or two the wireless network is still shown as active but their is no connection (websites will not load).

I'm completely new to Linux so I have almost no clue what could be causing this. I have tried connecting the notebook hardwired (Ethernet) to the router and get a perfect connection if that information helps any.

Networking :: Resolving Names From DNS Server ?

Jun 8, 2011

I have this in my resolv.conf file:

Code:

I have also used external DNS servers just to eliminate there being a problem with 192.168.1.67 (which many other computers are using successfully).

When I attempt to ping Google just to see if it works I receive this:

Code:

If I issue a host command against google.com I receive this:

Code:

I had thought that host and the name lookup routine would use the same DNS server and it should fail on the host command as well as the ping, but evidently not.

Server :: BIND 9.5 On Fedora Core 9 Not Resolving Dns Queries

Apr 21, 2010

I have this ISP grade Nameserver running on BIND 9.5 on Fedora Core 9 64 Bit.

Its been pretty working well for sometime until a last week when we noticed it stopped resolving for our clients using on our service.

It gives correct authouritative answers for our own ISP domain with the A, PTR and MX intact but does not return resolving queries back to clients.

Below are my files

This is the message from /var/log/messages

The 41.223.x.x and 41.215.x.x ip address are from our ISP subnet and so are our own clients being denied.

The box is also hosting our traffic graph server which is on a LAMP but listens on another IP/ethernet card.

So far the load on the server is minimal as is a Dell R200 rack server.

Server :: Troubleshooting/resolving Random Kernel Panic On Multiple?

Jun 22, 2010

I'm having a strange problem on some of our Debian servers. It all started about three weeks ago when we moved our virtual environment (VMWare ESX3) from a SAN to a NAS (NetApp). At first I thought it had to do with that move but since the other 9 servers are working perfectly I eliminated that idea. For over a year all 12 Debian 5 servers have been working great without mentionable failures. All servers are (where) up to date with the latest patches. About three weeks ago I started having kernel panics with the following message on three of our servers:

Code:
Code: Bad EIP value
EIP [00000000] 0x0 SS:ESP 0068:f6d7da18

Kernel panic - not syncing: Fatal exception in interrupt and other times it looks like just a dump of hexadecimal data. The only difference between those 3 servers is that they have several mounted shares connecting to the NAS using CIFS. So I was thinking that it might have to do with an update of some kind in regards to smb. I recovered an image from a month ago, before the troubles began, copied over the data and MySQL databases and configured the 'old environment with recent data' exactly the same with MySQL master-master replication, document synchronization and load balancing. This task I performed last night (no other way since it's a production environment). Up to this time neither of the two 'restored' servers had a kernel panic. The one that has not been restored is having one at random about every hour and a half. Following are the different versions between the 'at this time' working server(s) and the failing one:

Code:
FAILINGWORKING
samba-common 2:3.2.5-4lenny122:3.2.5-4lenny9
smbclient2:3.2.5-4lenny122:3.2.5-4lenny9
smbfs 2:3.2.5-4lenny122:3.2.5-4lenny9

Networking :: Can't Access Websites From Internal Network

Aug 28, 2010

I am in the process of setting up my own Linux gateway/firewall using two nics eth0(external network) and eth1(internal network). The Linux gateway hands out ip addresses using dhcp3-server, and uses iptables to route the traffic correctly. Clients are able to connect and access the internet...everything is working great, HOWEVER I can't access my apache virtual hosts websites from the internal network? They work just fine if i access them from the outside world

I can type ip of the web server, 192.168.0.201 and it shows the first virtual host listed in my /sites-enables/000-default folder. but i can't use any DNS entries. I don't have any internal DNS servers running. This doesn't makes sense, because if i replace the linux firewall/router with my normal linksys wrt54G router it works just fine.

Server :: Resolv.conf Was Edited, Server Stopped Serving Websites?

Feb 21, 2010

I'll preface this by saying i'm by no means an expert on Linux. A competant beginner at most.We have a dedicated server, the 'resolv.conf' was changed, specifically the domain that was listed (this is the primary domain).I only became aware of this change, when we get into work on Friday and all our sites were down - I attributed this to DNS fault as if I changed my host file (I work on a windows machine) and specifically routed to the domains to the correct IP address, the websites were served fine.I tracked down the resolv.conf change by quizzing a collegue. I then switched the resolv.conf file back to it's original state - luckily a backup was made so I am 100% sure that the current resolv.conf is the correct one.

change was made Friday morning, around 9.30am (UK time). It is now 5.05pm (UK time). The original change was made sometime on Weds afternoon, and the sites stopped serving between Thursday night and Friday morning.Does anyone have any idea how long it should take for the fix to be picked up? Will it be picked up? I just started to think that the change can't be picked up due to some DNS related voodoo.

Ubuntu Networking :: Can't Connect To .local Hosts / Websites On Company Network (DNS)?

Jun 27, 2011

Problem:Your company network has internal only hosts / websites with names that end in .local, e.g.Your freshly installed Ubuntu machine works fine on the network, has internet access, etc. but cannot connect to these particular systems.Testing DNS with tools like dig / nslookup works fine, but normal name resolution with ping / telnet / browsers does not work.Solution:1. Open a terminal window2. Enter the command sudo nano /etc/nsswitch.conf3. Change the following line:hosts: files mdns4_minimal [notfound=RETURN] dns mdns4to this:hosts: files dns4. Press Ctrl-X, Y, Enter to saveExplanation:Ubuntu ships configured to do name lookups for self-configuring networks, based on the AppleTalk / mDNS / Bonjour protocol. In the configuration shipped for the resolver, this protocol is considered the final aurhority for the ".local" top level domain, and DNS will not be checked. The above configuration change eliminates this and restricts lookups to (a) /etc/hosts file, followed by (b) DNS

OpenSUSE Network :: Network Login Starter - Set Up A Server - Centralized Username And Password

Jan 21, 2010

I'm new to networks and servers, been using Linux on the desktop for a while now but always relied on the company's IT guy for setting up everyting LAN-based.

Now I want to build up my home LAN, and want to do it with Linux. I've managed to set up LAMP and file share servers.

What I am looking for is information on what I need, and how to set up a server for the following tasks:Centralized Username and Password, that when the user logs into any one of the desktops in the LAN, it uses this for authentication

Something that allows this authentication to be utilized in other servers (file access, web access, router logging, etc.). Something to make it easier for continuing permissions from one service to another. e.g. I have IPCop filtering content, and it has provisions for tracking who is making which request if there is authentication going on. (optionally) to run a script for mounting Samba shares or mapped network drives so from one system to the next. For example, in whatever box somebody logs in, it mounts a server share ("smb://Myserver/users/<username>") to a local folder ("my_user_share").

So;user "fred" ="smb://Myserver/users/fred" and user "wilma" = "smb://Myserver/users/wilma" but both would find their respective one mounted under "~/my_user_share". This would be irrespective of which box they are loggin in with. If the server share location changes (new server/servername), I change it on the server so the next time they log in it points to the right place.

I guess it is similar to Window's Active Directory, though I'm not sure what it's called, how to configure it and what it is and is not capable of doing.

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

May 12, 2011

I have an opensuse 11.3 install which I want to set up as a network boot server to install Solaris 10 on a Sun Ultra 10 client. According to what I've read, this requires rarpd and tftpd which I've set up on opensuse, but also bootparamd which I can't find for 11.3. It seems it was last included with opensuse 9.2. Does anyone know if it's available, if I could use the suse 9.2 version, or any alternative?

Server :: Mysql For Multiple Websites?

Aug 1, 2011

I currently have a single mysql instance for a couple of websites. Both websites require that the user provide a username.

The thing I just noticed is that two people might choose the same username for both applications. Both of them would have grants to each others' tables, although neither would ever be able to access them, since they can only access through php scripts.

But, I'm now guessing this is not best practice. What does one do? Run multiple instances of mysql for several websites?

I have managed to configure AWstats to work from one server to access the log files for multiple websites on multiple servers and even managed to write a little front end php site to access all the different conf files. I want to know if there is a way of combing two conf files for the same site but are on two different servers in a loadbalanced situation. so my conf files look something like: [URL].. I have to monitor bandwidth for our websites and its gets tedious switching between the various conf files for the same site and totaling it up so I was hoping I could combine the output of both conf files on screen using some funky command in the awstats.pl script

Networking :: Websites Won't Load - Using OpenSUSE 11.2

Mar 9, 2010

I'm a first time poster and new to openSUSE. I've had a small amount of linux experience and even studied UNIX a few years ago - unfortunately, to paraphrase Homer Simpson, "as something new enters my brain something old has to leave". In this case nearly everything I learned about UNIX

Anyhow, ms problem is this. I've installed 11.2 with KDE desktop. Using either Firefox or Konqueror browsers, I am finding it impossible to display any webpages, other than Google. All google websites, such as gmail, calendar and searches work perfectly. Unfortunately, I can't directly enter a url into the address bar nor can I link from a google search.

I've hunted high and low for a solution but have failed to find one.
