Ubuntu :: Sudo: Unable To Resolve Host Username Getting Error?
Nov 26, 2010When I try to launch something from terminal, it shows this error.

My computer always had this name and I never had concerns related to his name. So, what's wrong now?
Ubuntu :: Sudo: Unable To Resolve Host / Setting Up Network Sharing With Samba?
May 21, 2010I 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.

General :: Host Key Verification Failed / Resolve This?
Mar 29, 2011I 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...
Ubuntu :: Can't Run Firefox - Thunderbird Without Sudo / Resolve This?
Jan 19, 2010I just migrated into Ubuntu 9.10 from Windows and moved my mail profiles and also my bookmarks to Thunderbird and Firefox.
I can't see the Mail profiles and messages unless I run "sudo thunderbird" and I can't save or edit bookmarks in Firefox unless I run "sudo firefox".
Probably it's best if I don't run Firefox or Thunderbird as root, eh?
I've tried changing the file permissions for bookmarks.html, but no luck. And haven't even tried to tackle the Thunderbird issue yet.

Ubuntu Networking :: Could Not Resolve Host Name?
Apr 29, 2010I'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;

Any ideas what could be causing this?

Slackware :: Php Curl Can't Resolve Host Getting Error?
Jan 26, 2011I 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.
Debian Configuration :: When Open A Web Browser - Can't Resolve The Host Name
Mar 29, 2011I'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?

OpenSUSE Install :: Can't Resolve Host For Yast2 In Console?
Sep 3, 2011It'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 Servers :: Unable To Resolve Host / Hostname Is Set To (none)?
May 25, 2010I 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.

Ubuntu :: Changed Host Name And Now Get An Error Message From Sudo

View 9 Replies View RelatedNetworking :: 'Unable To Resolve Host Address' Errors With Newer Distributions
Mar 10, 2010I'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.
OpenSUSE Install :: Unable To Upgrade To 11.4: Can't Resolve Host / Error Code: Connection Failed?
Apr 1, 2011I'm currently running 11.3 and decided I'd try upgrading to 11.4 following the instructions here: SDB:System upgrade - openSUSEUnfortunately, my attempts are defeated at the point of trying to refresh the new repos; I get the following message (for the oss repo, in this case):
Download (curl) error for 'url':
Error code: Connection failed
Error message: Couldn't resolve host 'download.opensuse.org'
With 11.4 replaced by 11.3 in the repo url, it refreshes just fine. The only repository that works when I change 11.3 to 11.4 is the Packman repo. I'm not really sure why the connection fails for 11.4 but not 11.3!
Further info: I have an old router with no IPv6 support, but have IPv6 disabled system-wide. I can enter the url for the repositories into firefox and they come up just fine - it's only with zypper/YaST that I get the above error message.I also tried upgrading using the network CD but ran into the same sort of problem. In this case it may be because the CD installer doesn't disable IPv6. (I didn't want to download the DVD at my connection speed, and the KDE live CD is not listed as suitable for upgrade).
Ubuntu Servers :: Unable To Resolve Host URL - Domain Setup / Home Based Web Server
Jan 18, 2011I have setup a home based web server to host a photo blog for myself and my friends. I will be running wordpress and possibly a phpbb3 forum. I'd like to open this to discuss server administration, server setup, and server maintenance. However, I have a pretty good start on all of those but serving a domain name to my static ip. Here my static ip is 24.10.202.144. I registered a domain through [URL]... It appears that I have the domain working to forward to my ip. However, I am still getting this output file from apache.
[code]...
I have tested the domain name across a few different computers on different ips. It works appropriately. I just want to make sure I have it set correctly on the (apache) server side of things. Then I can get more into Zone Editing etc.

OpenSUSE Network :: Cannot Resolve Host Names On Local Network?
Mar 9, 2010I have a mac and an openSUSE box connected wirelessly to a router. From my mac, if I ping the Linux machine by both ip address and hostname "elmo.local", I get a response. If I ping my mac from the Linux machine using its ip address, I get a response. However, if I ping the mac from the Linux box using its name "kermit.local" - nothing!
This means in order to share files between them via the network, I have to use the ip address rather than name, but I'd rather not. When I had Ubuntu installed instead of openSUSE this all worked fine out of the box, so I'm assuming it's a problem with the setup of openSUSE rather than the router or the mac.

General :: Transfer Large Number Of Files Host To Host
Oct 20, 2010I have two servers, one has an empty / and the other has a subdirectory with a large number (4 gig) with many, many files. I need a way to transfer the files en masse from the server with the large number of files to the one that is essentially blank.I don't have space on the used host to simply gzip all the files. I've googled this and see that there may be some combination of tar and/or gzip that will let me do this with some sort of redirection.
I really need and example line of how this can be accomplished. If my explanation seems rather sparse, I can supply more details.
