Ubuntu :: Changed Host Name And Now Get An Error Message From Sudo
Aug 1, 2011
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.
It reads dpkg was interrupted you must run sudo dpkg manually to correct problem. I tried the terminal options and still nothing.. The thing is I am trying to install other packages and it says have to close that one out first.
When I try to connect to my SUSE server from other one this appears: Remote host identification has changed. I deleted entry in know_hosts but it still working wrong, showing me this message. What could be the cause of this problem??
Occasionally, when startx, I got the error message: "Monitor output has changed" error message ( and sometimes it appear while I am working in X too but rarer). Whenever this happened, my screen changes to "1024x768" resolution when normally it is "1280x800". I click on "Configure", a "Configure Display" windows appear and I have to change the screen to Size"1280x800" back (since it would give me 1024x768"). Besides, the number of error messages will be up to 50s, 60s message. (This "Configure Display" is what you get when you go to "Application->System->"Screen Resize and Rotate" (KRandRTray)) My computer is Toshiba Satellite L500, the distro is Slackware 13.37. It was just installed so all the configuration is out of the box.
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:

I install and configure the vncserver following and reading 1000papers, but all of this present the same problem; when i try to connect to my vncserver,recive this mesage: unable connect to socket: No route to host (113) The OS version is Fedora Core 14 and tigervnc-server i try different solutions including:Allow TCP connection modifing files /etc/gdm/custom.conf and /usr/share/gdm/gdm.chemas Disable SELinux removing iptables Here follow the vncserver configuration:

The ip address of the vncserver is correct because i can do ssh on it. Where or what can i do?
I was recently messing around learning chgrp commands, and set my (only) user account to a different group. Now whenever I try to sudo a command, I get 'john is not in the sudoers file. This incident will be reported' message.I *seem* to have a root account (one is listed in System->admin->users and groups), but I'm almost certain that the password for it would be one of 3 things, and it's none of them.
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:
On a Xp host I installed last version of VirtualBox and I created a 9.10 Ubuntu 'guest'.While I can surf the net, I cant 'sudo apt-get update' nor do a 'reload' from 'Synaptic Package Manager'.
PS Here are some facts: << Host: PC: Thinkcenter 9640-7BG Network adapters:
now my system does not connects automatically when fedora start's to eth0 i have to connect it manually by pull down menu in the beginning hostnname was dbe272b22.dslam-172-17-161-245-0532-474.dsl.cantv.net i do not remember if the last part ".cantv.net" was there.... i changed hostname "dbe272b22.dslam-172-17-161-245-0532-474.dsl" maybe ending with ".cantv.net" with system-config-network for hostname "edicta" i modified /etc/hosts by hand twice, now do not remember what i did exacly but here you can see /etc/hosts
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

Im trying to instal Sun Virtualbox but when download completes and I click on install I get the following error>>Message did not receive a reply (timeout by message bus) I wont even bother with this software if there are others out there that are as easy to use. I used it on Windows and thought it was great ! (thats how I eventually switched to Linux, by using it virtually at first)
I would like to configure visudo to authorize user to start only one application with sudo on one peculiar host and forbid everything else so, after reading the man, I came up with :
Code:
Select alluser    ALL = (ALL:ALL) !ALL user    host_name = /usr/bin/application
Many of mails sent from my mail server that are in Queue;The main reason is deffered by domains like yahoo,aol,etc.but there is one more error that i keep getting and that is Host Unknown,Below is an example from mail log,The catch is,test mail sent on the same email id sent from my personal mail from the same server i.e. url was deliveredHowever,another mail containing client information sent from customercare@mycompanysdomain ended up in queue.
There are more examples of the same,around 20 domain have the same problem.
i actually registered here because i'm done with my knowledge of linux, errors which cause my sys to hang and/or reboot randomly after some time. They occur while the system is under heavy cpu, heavy mem-read-write, mediocre mem fill, heavy hdd io (for ~20 seconds every ~5 minutes).
problem background we ordered two identical PCs (specs below), one of them brought those sata errors quoted below from /var/log/messages, the other one runs flawlessly. Same Hardware and Software Configuration. Faulty one brought reallocated sectors right at start, mass seek errors, read errors. 1st try: swap cables, change bios mode ata_piix <-> AHCI. Didn't work. Went away for repair. Stupid Techie did only swap hdd, so problems occured again. Shipping for repair again. Board AND hdd exchanged. no more seek/read errors, no more reallocated sectors. But similar sata problems right after 3 days of previously described workload. Following logs are from after the last repair.
I been running both OS's for a few months now with no major problems besides wireless internet issues. Today, however, as I go to boot my laptop up, the Dell logo loads with the F2 and F12 boot and setup options which both work. Directly after that though I get the message "GRUB loading. Symbol '?' not found. Aborted. Press any key to Exit." then it repeats when I push a key, and then it tells me to press F1 to retry, F2 to go to setup, or F5 to run diagnostics. It passes all the tests in diagnostics. I've tried booting off of the ubuntu cd I used to load it initially with no luck. So I'm stuck at either that error message or in setup but I can't go any further, and it does not change anything when I tried to boot from the cd.
Gives error message permission denied. I've seen this in your forums but I still haven't found the fix. I've tried the latest release Wubi downloader too. This one is ran from a CD. Version 10.04
I'm trying to install ubuntu 10.10 on xp,but, after waiting around 2 hours per instalation I received a error message that says:" unbuntu installer : and error occurred: coercing to unicode: need string or buffer, none Type found. for more information see log file C:1customerlocals-1 empwubi-10.10-rev197.109. I tried on one particion make just for it then I even tried on xp on C: I even put it on a pendrive but my bios is old and do not provide for usb booting. The other thing I have to try is making a boot cd but for one reason or the other , my recorder do not want to recornized my cds- rw and right now I do not have any regular blank cds . That will be my next step. Note: Ubuntu appears installed on the the control panel "add or removed programs" but not in "all programs" list. I'm a novice on this so maybe the answer was posted but I couldn't find it. Looking ahead to try it and be part of the linux team.

I have Ubuntu Jaunty & Linux Multimedia Studio 0.4.2. In attempt to update to LMMS 0.4.5, I downloaded & attempted to install : lmms_0.4.5~ppa-1jaunty_i386.deb and got the following error message : Error : Dependency is not satisfiable : lmms-common (=0.4.5~ppa-1jaunty). What went wrong and is there an easier way to update ? Also, should I remove the older version or just install the latest on top of it ?

I have burn two different cd but the result is always the same.Is it a hardware problem or the cd is not correct?I had the 11.2 version in the same pc without any problem for a long time.
