I'm trying to troubleshoot some strange networking problems. The pattern seems to be that only newer distributions are affected. CentOS 5.4 and Ubuntu 8.04 work fine out-of-the-box. But Arch, Sidux, AntiX, Fedora, etc. show the same pattern of errors.Certain websites cannot be found unless I disable ipv6 in Firefox. And certain addresses cannot be resolved using various terminal commands (wget, apt-get, yum, etc.). What I would ideally like is a permanent solution, perhaps changing some settings on my router, so that I don't have to deal with this each time I test-drive a new distro. I have a hunch the issue has something to do with my DSL provider (Fairpoint) filing for bankruptcy.
One more piece of information that may or may not be relevant: I recently switched a website from one hosting company to another. I noticed there was a delay of several days where I saw the old version at the old host, but viewing the site at a friend's house or the coffee shop showed the new site on the new host. This leads me to suspect DNS issues perhaps, but this is not an area of expertise.
I have a strange problem with using curl function in php on slackware machines. So far I tested this on 2 PCs. I din't test it on any other distributions, so I don't know if it's only slackware problem.
Problem is that I can't use php curl in normal way. It can be tested wit simple code:
Code:
$ch = curl_init("url");
$content = curl_exec($ch);
if (curl_error($ch)) {
echo(curl_error($ch) . "<br>");
}
echo($content);
When I'm opening this php script in browser I'm getting error message:
Code:
Couldn't resolve host 'google.lv'
but I can use curl command in terminal, also it works when I run this php script in terminal like:
Code:
php ./curl_test.php
So problem is not in curl or php itself, but in apache, because this happens only when this script is running in apache.
Searching google a lot, I got to conclusion that apache can't read /etc/resolve.conf file during startup. Strange thing is that it happens only when httpd starts during system startup, but if I'm stopping httpd and starting it again manually, it works as it should until I'll reboot my PC. Restarting httpd also do not work, I need to do start -> stop.
I think that apache reads /etc/resolve.conf only when it starting up and as I have DHCP, maybe network is still not ready at the moment of httpd startup.
I didn't try to configure php as php-cgi instead of apache module, I think then it would work normally because each php script would be separate process and it would read dns information each time, so the same like starting php script in terminal with command:
Code:
php ./curl_test.php
I think there are some ways to workaround it, e.g. delay somehow start of httpd during system startup, or something like that, but I want to find reason of this problem and make it work without any workaround.
I just built out an Ubuntu Server 10.04.
My problem is setting the hostname. I cloned the machine, then normally on the clone, I would change the /etc/hostname and /etc/hosts file.
However, when I do this, upon restart, I get the message, "init hostname main process (some process number) terminated with status 1"Then, when the machine finally boots, the hostname is set to (none). Literally has braces like: user@(none):
I've tried: sudo hostname machine_name but it says can't resolve hostname (none).
I've Google'd around a lot but can't get it. It may have something to do with 10.04? I have been using 9.04, 9.10 with no problems.

My computer always had this name and I never had concerns related to his name. So, what's wrong now?
Centos 5, After switching out server to another provider the website responds as it should but the server is unable to establish connections to remote servers. Yes the internet connection is fine, I'm actually working on the server remotely.

and I've updated /etc/sysconfig/network to reflect the new IP address.
If I have a dnsmasq server and it dished out a IP address that I don't want it to and it still gives it to my machine no matter how many times I restart windows and issue ipconfig /renew|release or enable/disable the adapter, how do I force it to give my windows machine an IP I want it to have?
The only way I've accomplished this in the past is by rebooting my slackware system.
I am having a problem with Ubuntu 10.04. I was setting up network sharing with Samba. Set up went fine, then I decided to change the hostname.
Following instructions I found on the web, I edited etc/samba/samba.conf to reflect my desired hostname.
Now I have to use superuser to run synaptic or update center. I don't know what else I have "broken".
I would like to change my hostname, if I did it incorrectly for 10.04 please enlighten me.
Whenever I try to use the sudo command in the terminal I get the message unable to resolve host, then my computer name. Here's some command line output with some files which I think may be causing the problem. I have Operating Systems homework and need sudo

I'm having really weird and frustrating DNS issues with my clients unable to properly resolve the server's ip address. They can resolve each other's, and outside systems, but not the server - at least, not correctly, and not all the time.
I have one Ubuntu server set up that does both DHCP and DNS serving to the Windows systems. The server has DNS forwarding turned on to forward to OpenDNS's servers (I've tried using my ISP's dns servers but the problem remains).
The server is *not* set up as a firewall; I am actually using a DLink router for that, and the Dlink is *not* set up to serve up DHCP nor DNS.
What I am getting is that my clients - and there are nothing but Windows clients - will not resolve the name of the server. For example, if I do: ping linuxserver
I get back a false IP address of 192.168.0.64 (and I've seen once a 192.168.2.49).
If, however, I put a dot in there: ping linuxserver.
I get back the *correct* IP address of 192.168.0.2, and thereafter, ping'ng linuxserver without the dot will work. Until the dns cache expires, either naturally or with ipconfig /flushdns on the windows clients.
The client *are* getting valid dhcp leases and can resolve everything happy-happy, they just will not get the proper address of the server 100% of the time.).

this issue which has suddenly occurred on both my Desktop and my Laptop. When I try to configure an IP address to any interface I get the following error....
uadmin@Ubuntu:~$ ifconfig br0 addr 192.168.10.1/24

ifconfig: `--help' gives usage information.

I get this for ethernet interfaces as well. I do not understand what is different as I was able to configure the ip address only the day before yesterday on the laptop..? The Desktop has had this issue for about 3 weeks now.

I installed Wicd from the Slackware DVD and was successfully connecting to the internet for the past few weeks.I do not know if the following caused my problem or if it is something else that I did:All of a sudden (probably something that I did) the wpa_gui screen started to appear on my desktop. I just closed it.Today, in a moment of stupidity, I said "Who needs this wpa-gui thingy?! I know, I'll just use pkgtool to uninstall it. Then, if I need it, I'll just use pkgtool to reinstall it!" So, I did. After my next reboot, you guessed it, no wireless.
Wicd seems to do everything it used to do, except connect. I get the error msg "Connection Failed: Unable to get IP address." I see my 'connection' listed and it is still set to "Automatically connect to this network" but it doesn't.So, is it the wpa-gui app that I 'uninstalled' or is it something else that I might have done?'m having an issue where some of my machines hostnames are no longer able to be resolved after setting up a mythbuntu backend to allow netboot. Also it seems that which machines hostnames get resolved is not consistent. (ie sometimes one gets resolved and sometimes it doesn't) I suspect that it has something to do with the changes I made to "/etc/ltsp/dhcpd.conf" to get the netboot running.
I have a Verizon DSL modem/router as 192.168.1.1. Up until playing with the "/etc/ltsp/dhcpd.conf" I saw hostnames of all of my machines show up in its network map. Now, some of my machines still get network access but their hostnames are no longer resolved. What did I do wrong? Here is my dhcpd.conf file:
Code:
# Default LTSP dhcpd.conf config file.
authoritative;
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.2 192.168.1.250;

I know that there are multiple threads with problems like this, but still i didn't found my answer.
The situation is like this:
I have a local server and a remote server, i did a ssh key swap so i can log on to the remote server with no problems (automatically logging on, no need to enter pass or login).
I've made a script that copies (with SCP) a file FROM the REMOTE server TO the LOCAL server (NOT FROM the LOCAL server to the REMOTE server !!!!), and then i get an error like code...

I've just installed Debian Squeeze from a live CD. When I open a web browser (be it iceweasel or epiphany) and try to go to google.com, it tells me it can't resolve the host name. [Edit: They do, however, allow me to go anywhere on debian.org, minus the search feature] I also get the same error when I try to go to my website running on a local server. However, when I type the server's IP address (192.168.0.10), it goes to the website fine. Basically, any program I run that needs to resolve a host name returns an error, with the exception of the host command:
I've tried changing my DNS server IP from 192.168.0.1 (my router, configured to provide DNS) to 192.168.1.254 (my internet modem, also configured to provide DNS). That didn't help any. Then I changed my DNS server IP to the same one used by the modem, and now everything works.
I've tried googling my way out of the issue, and I've found where someone had the same issue as I've got and fixed it by adding "blacklist ipv6" to their /etc/modprobe.d/blacklist.conf file, but that didn't work for me.
So, recap: Why does resolving domain names fail for certain applications (except the "host" program) when the DNS server IP is that of my router or modem (which works fine for all of my other computers), but suddenly works when I point the computer straight to my ISP's DNS servers, and how can I permanently fix the problem?.
It's been a while since I've use linux (specifically suse). But my wife and I are expecting our first child and our office/second bedroom is now being converted into the baby room. I built the computer that is currently in there and it is a really nice one that I do not want to get rid of. Two 500GB Sata2 drives and 8Gigs of RAM (not to mention my quad-core Phenom AMD processor and sweet asus motherboard) -- I just can't get rid of it. So what I planned to do was turn it into a small home server. I did some research and kept coming back to using opensuse as the server. I read this article The Perfect Server - OpenSUSE 11.4 x86_64 [ISPConfig 2] | HowtoForge - Linux Howtos and Tutorials and it seemed to have just about everything I'd like to do (maybe some extras that I don't really need, but might in the future). Everything was going fine until I got to a certain point. The install went fine, and I was starting to customize some of the settings for my own home setup. Now, the problem...
I've gotten to page 3 of the tutorial The Perfect Server - OpenSUSE 11.4 x86_64 [ISPConfig 2] - Page 3 | HowtoForge - Linux Howtos and Tutorials
and I am installing packages through yast2, and all the packages installed fine except for 'compat-readline4'. I think this is a form of command line editor or something to do with that. I am sure I am going to need it to finish the server set up, but I can't get it installed anywhere. I've tried to install it by pointing directly to the mirror found at rpm.pbone.net and still I get nowhere.
Yast2 auto refresh seems to fail everytime I run it. Even though I installed all the other packages, I get an error message that says it can't get the medium. When I look at the details of the error it says it can't resolve the host for downloads.opensuse.org.
Ubuntu Server 9.10, with apache, proftpd, mysql and the goodies.
I have wordpress installed and setup under /var/www/
The LAN IP address resolves perfectly to the index.php
However I can not get my WAN IP to resolve. My ISP blocks port 80, so I have my router setup to forward port 81 externally to port 80 of my server. I know the port forwarding is setup correctly and working, because I can go to websites like url and test that port 81 is indeed open.
I also have DynDNS setup on my router and through an account with them, to update my IP address with any changes, to a host name. But because port 80 is blocked I have to access it with, host.name.org:81. Ive had this system up and running before with no issues. Now I can not get the host.name.org:81 to resolve.
Neither can I get my ip address xx.xxx.xx.xxx:81 to resolve.
I just changed my CentOS server from DHCP to static IP address. After the change, I cannot ping other hosts on the same subnet.

Here is a glimpse of my IPTABLES
I see in the column of sources the addresses being resolved to domain names is there a way I can stop this?
