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 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):
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).
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.
eric@(none):~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface code....
sudo still works, but every time I run it, it says it's unable to resolve the host. I tried to change stuff in visudo, but there wasn't anything about the host as far as I could tell.
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'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 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.
i get the following error when i try to install autoten: root@Tex dan]# rpm -Uvh [URL]... curl: (6) Couldn't resolve host 'dnmouse.org' error: skipping [URL]... - transfer failed from reading other posts, it sounds like a dns error, but i don't know what to do to fix it.
I'm trying to use a flash drive to try to repair the Intrepid installation on my netbook.
when I drop to a terminal and try "sudo apt-get update" i get
Code: sudo: unable to resolve host ubuntu E: The method driver /usr/lib/apt/methods/https could not be found E: The method driver /usr/lib/apt/methods/https could not be found
This is an example of the error I receive when trying to do an update via YaST, YaST2, or zypper. Basically, curl is broken. With out it functioning normally, I can't use openSUSE's update mechanism to fix my system. Need to find a way to manually fix / upgrade curl.There was an error in the repository initialization.'Updates-for-openSUSE-11.4-11.4-0': [|] Valid metadata not found at specified URL(s)History:

My latest issue seems to be with Yum; more specifically, I don't think it can contact the main "updates" server to see if there's any actual updates available. When I try, I get this:
I try to find what users visiting in terms of websites and the stations.webalizer do nice graphs.but, Squid log file only keep IP address with websites.I need squid to keep IP address along with host name and username of the person.how do I do it ?
I am thinking update squid to Dans-guardian.
Does Dans-guardian keep all username and host name ?
Writing a program that finds the IP address of a host name. Sorry forgot to include the line numbers, but where the $$$ is where the syntax error is. The errors are syntax error before "{" token and syntax error before "if". I've looked throught the code for a couple hours and can't figure out what's causing it. The code is attached below.
I am having a problem with two linux boxes I have. They are running Centos 5.3 and Centos 5.4. The problem is that when I log in, this file /etc/host, under the etc directory get appended the username I am logging in as, the IP address I am logging in from, and worse, the password in clear text.This is the format it uses:username@IP (password in clear text) [Tue Jan 12 2010 13:00:26 -0500]Is it possible for someone to tell me what is this about, and how to stop it?
I'm with Linux 2.6.32-25-server #44-Ubuntu SMP Fri Sep 17 21:13:39 UTC 2010 x86_64 GNU/Linux , Ubuntu 10.04 Server And I wanna execute the next script in bash profile code...
I have a lenovo x200 laptop running Fedora 14, fully up to date with the Fedora repository. Seemingly out of nowhere, some websites will no longer load. First it happened to www.facebook.com, next (after a day or so) wikipedia.org, now the Fedora forum. Other Internet access seems fine, but when I try to go to these pages I just get "unable to find host" errors. Its totally bizarre. It first happened in an airport so I thought it was just a strange network there, but now it happens at home. I can't get on these sites in firefox or elinks browsers (in a terminal) BUT I can ping both sites no problem. Also, the other computers in this house have no problem visiting these sites.
I am working on different versions of Ubuntu & I looking for a script that will prompt the user to enter the host name & user name that he wanted for that system at initial boot up.
I'm trying to connect with my server via telnet, but when i sent the command (telnet xxx.xxx.xxx.xxx Port) doesn't works and shows then follow error: Unable to connect to remote host: Connection refused, It happens with any port. Is strange but my telnet services works (telnet xxx.xxx.xxx.xxx), In addition, i tried with firewall enabled and disabled and the problem still happens. My centOS run on virtualbox.
I'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:
I am suddenly not prompted for my password when I run any command as sudo on a few of my Ubuntu servers.
if I run sudo -K, the session is cleared, and I am prompted again for my password, however it saves/caches it until I run sudo -k again even if I log out and back in. I want it to prompt me for my password, as it should (and did) by default, for security.
I have a problem when I want to use su I get this error:Code:su: pam_start: error 26I have googled it so I found this topic (http://www.linuxquestions.org/questi...r-26-a-615024/) but it didn't really help me. There was a reply on that topic and his question was what the output of this was:
I was trying to install a couple of the sun packages to have and after the install I get the follow error. Xsession: unable to start X session--- no "/home/username/.xsession" file, no "/home/username/.xsession" file, no session managers, no window managers, and no terminal emulators found; aborting. I am now not able to log into the system at all....Can someone tell me what I've done wrong? How can a repair this?
