Server :: Chrooting Attempt Of BIND9 Failed?
Jun 18, 2011
I followed blindly this how to : [URl].. out of laziness and then for some reason bind9 didn't want to start. So I tried to apt-get remove it, but when I re-install it, it failed because
Code:
chgrp: cannot access `/etc/bind/named.conf*': No such file or directory
so I assume the chrooting stuff I did is in the way, but I know very little about chrooting and permissions ... how can I undo the following things I did :
Code:
/etc/init.d/bind9 stop

I have installed CentOS 5.5 final on VM ware 7.0 workstation.... and I was trying to install and configure bind9.. it installed alright but it refused to start because named.conf is not in the /etc/ directory. I have copied the template for /usr/share/doc/named/* to (/etc/ and /var/named/) the appropriate directory but it still fails but on it does not gives me any error message. Oh... least I forgot I was trying to configure it as a cache only server for now.

I installed from a live CD when it came to selecting the partition I re-sized the partition that Ubuntu was on because it was 68 gigs I shaved off 15 gigs for SUSE. Then I selected this new 15gig partition to install SUSE on, everything went fine with the installation I was tinkering around on SUSE but of course I needed internet access, so I go to get on Ubuntu where I had my file with my network key. I restarted expecting to see the usual GRUB boot-loader screen only now with an added option for SUSE. Instead I see an entirely new layout for the GRUB boot loader and all that is listed is SUSE, Failsafe SUSE, Windows XP, and Floppy. The Windows is my XP install and it loads fine sadly it is actually what I'm using now because it is the only thing left that I have my network key saved so I can get on this forum.
Looking on SUSE I notice that the 50gig partition formerly known as Ubuntu still exists I figure no problem add the partition back on to the boot-loader and I'm good to go. Added it and when I select to load it nothing happens it starts to then reverts back to the OS list. Does anyone A) Know how to resolve this or have any ideas. B) Think I can at least copy files off that 50 gig partition to an external hard drive.

When I try 'makebootdisk' and get to the 'format' stage, it tells me: "The attempt to format the floppy disk in /dev/fd0 has failed ..." The disk is fine, and can be read from, but the above msg. shows up instantly -- the light on the drive doesn't even come on. I'd expect this to be a routine problem but I can't find any solutions either here or on the web.

I learned that, even while on Linux, using Iceweasel/Firefox 3.0.6 is not safe. So I tried to update the browser for my PPC G4 iMac (256 MB RAM, 800 MHz processor).
1. I downloaded a backported Iceweasel .deb from URL...
2. I then tried to install it with dpkg -i PathToIceweasel.deb
3. There was an error. I remember seeing xulrunner-1.9.1 is not installed. I tried to install that with apt-get but it was not available.
4. Now when I click on web browser I get the error "Failed to execute default Web Browser: Input/Output error".
5. What can I do without having to reinstall?

I made an attempt to backup my system (karmic koala) using this routine. cd / then sudo tar cvpzf backup.tgz --exclude=/proc --exclude=/lost+found --exclude=/backup.tgz --exclude=/mnt --exclude=/sys /
The process of backup went on for a very long time, which is probably normal. On returning to the computer in the morning, it was in suspend mode and would not power on via the usual method,tapping power button. So then I used the reset button, and after booting up a message appears on the top right that reports "Install problem! The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator."
Is there something wrong with the statement that was used for backing up the system? Also when I attempt to login it does not work now either, it eventually returns to the login user selection. So is there a possibility the backup finished and then there may be a chance the system can be restored from the backup file? I have tried booting up with a live cd and could use some advice on how to navigate with terminal to root of the system and see if the backup file exist even, have been unable to get to the root folder(where the backup would be) with the GUI method via live cd.

My buddy has a computer with a problem and hes asked me to see if I can retrieve the data documents from the computer. The subject computer is a COMPAQ PRESARIO SR5030NX with a Pentium 4 cpu, 3.2 GHz, 1 GB RAM, running Windows Vista Home Basic.
His goal was to create a dual boot computer UBUNTU and Vista. What he did was to install UBUNTU, partitioning the computer in two partitions. The computer is now giving an error code of 21 when GRUB Loader starts up. Is there a restore disk or some kind of utility that can undo what was done to the computer. He has no backup disk.
I tried Recovery Commander Ver. 3 made by Avanquest but as their website indicates it�s for XP. They never updated it for Vista and Windows 7. Is there a utility that can undo some of the changes that were made to the machine when UBUNTU was installed, albeit, unsuccessfully.
(1) I have an HP PC running XP professional and I was wondering if I take the hard drive out from the COMPAQ and rig it to my HP via a SATA/IDE to USB 2.0 Adapter device would I be able to see the contents of that COMPAQ computer that had Vista and now UBUNTU.
(2)What about attaching the COMPAQ internal hard drive and attaching it to my HP as a slave drive.
(3)Can the UBUNTU disk going to help?
Were just after the data files and not software programs.

I've searched lot on forums but couldn't find a related post. My problem is I want to hide my mail folders when login attempt in Evolution has failed. I dont use Remember password option so everytime I'm prompted for password.
When I give no password and escape that dialog, I can see all the mails that have been already downloaded form my gmail account. If any of you guys know already existing post, please redirect me to that one.

I think the installation caused the corruption of the partition table. I removed the last 3 logical partitions and gparted correctly reported the 2 remaining distros and the swap. The problem hopefully will be solved when I reinstall those distros. I have a 160 gig HD with 3 Linux,1 swap,and a Windows partition. I attempted to install PCLINUXOS unsuccessfully. When I rebooted I had the same grub. I checked gparted and it indicated all 160 gigs as unallocated. fdisk shows the partitions. and indicates one partition as empty where I attempted to install PCLOS.
No problem in accessing any of my distros, but currently I can't make any changes to my HD. I've tried parted magic and there was no solution there. I have been unable to download the Ubuntu Rescue remix. Is there a way to restore? I haven't used fdisk or cfdisk for that purpose. I am beginning to think I would need to delete all of the partitions in the extended.

A few minutes ago I was using google chrome when suddenly the scroll-lock indicator on my keyboard turned on... I pressed the scroll-lock key, but nothing happened, the light remained. I opened a terminal and ran "top" to find what processes were running when I was automatically logged out. I logged back and checked the logs and found the following entries in my auth.log:
Code:
CRON[2971]: pam_unix(cron:session): session opened for user root by (uid=0)

especially to ubuntu server 8.04 because it doesnt use a GUI. Now my question is on how to insert IP address in configuring DNS server using bind9. Actually i'm using this guideBut i m not sure on how to insert IP addresses on the primary master and secondary master. Should I insert the Ip address that i found when i type ifconfig ? or Should I assign a new IP address.I have set up a webserver, DNS server, File server and mail server on a virtual box. For now, at first, im working with the DNS server or should I work with the web server first?what should I do?

I have a web server on my local network with a couple domains facing the internet. When I visit these domains from within the network I'm directed to my routers configuration page due to hairpin NAT.
So I installed BIND9 on the server and set up my forwarders to Google DNS to act as a Caching Nameserver. Then I set my routers DNS primary and secondary nameservers to the IP of the local BIND server. Everything is working great.
Now I need help configuring BIND so that the domains hosted on the web server within the network are routed to the web server and not the routers configuration page.

Our system is based on RH4 and is using pam_tally and faillog to record failed attempts and to lock users out after 5 attempts. We have a requirement to provide a normal (non-root) user logging onto our system, with information regarding the number of failed logon attempts made on their account before the current successful logon (similar to the functionality provided by HP Protect Tools on Windows). My first idea was to add 'faillog -u $USER' to the bashrc, however by the time the bashrc is run - the user has been successfully authenticated and the faillog has been reset back to zero.

The thing is, I've created a new local zone here (called "local.lan"), and, aparently, it is working fine, and DHCP3-SERVER is updating DNS info through the controls.But sometimes I get some strange answers from the server, like when I do the "arp" command in one of the clients, and get the server's hostname "mixed" with it's own reverse, like this: "dns.local.lan.2.168. | ether | 00:02:1e:f5:61:74 | C | eth0". Other thing is that sometimes my DNS don't update when a computer "enters" the lan. In the /var/log/syslog the DHCPOFFER appears, but the information about the DNS update isn't there.So, I would like to show you my named.conf file and my local zone db file, and get some feedback from you (what would you change... what is wrong...).

I'm running bind9 on Debian 6. I have a primary domain, 44kg.net, fully configured and working dynamically (the server also runs DHCPd and updates the DNS records properly).
[Code]....
To access my externally-facing website, which has a blog and a forum which are keyed to the external domain, I set up the domains in bind so they would resolve to the server's internal IP. This worked great for a few months, then inexplicably ceased working. I didn't touch anything, but it coincided with our router dropping its VLANs. I've moved the server to a different location and it's still not working properly. Whenever I try to lookup the external domains, I get SERVFAILs. This is annoying because the internal domain is fully working and I copied the basic settings.

Location and syntax of named.conf in Ubuntu's version of BIND 9. I already have an HTTP server (in the form of Apache) along with forum software set up on my Acer netbook. However, the only way I can access the forum software is if I type in my IP address. How do I set up my named.conf to get the IP address to redirect to a domain? I already have my resolv.conf configured to allocate a domain to the IP address, but testing the ping of the site returns a "No such domain" error.

I'm trying to set up a bind9 server for my home network, I have all my IPs set to 10.0.0.X. I would like the forward and reverse to be simply "machinename", not "machinename.domain.com", as I don't want to type a domain everytime.
In my named.conf
zone "net.local" in {
type master;
file "/etc/bind/net.local.ns";

Im using bind9 as DNS server on my LAN, but it does not seem to translate its own hostname correctly for some reason. Other hosts is translated correctly, the problem only seems to apply to the DNS host itself. if i "ping <server_hostname>" from the server, it translates correctly. But if i "ping <server_hostname>" from the client it only says "unknown host" The client has the correct DNS-server assigned. How can i start troubleshooting this?

Is leading whitespace significant in bind9 config files? This reverse lookup file (/var/chroot/bind9/etc/bind/zones/rev.168.168.192.in-addr.arpa) did not work; /var/log/messages had "zone 168.168.192.in-addr.arpa/IN: has no NS records".Inserting 3 spaces before IN in the NS line fixed it:
Code:
; IP Address-to-Host DNS Pointers for the 192.168.168.0 subnet
@ IN SOA CW8vDS.localdomain. hostmaster.localdomain. (

Reading the man pages and netsearching, I did not find anything about indentation requirements except for "This is usually indented for readability, but the indents are required syntactically" here.Although the above file works, named-checkconf reports an error in it:
Code:
