CentOS 5 :: Bind-chroot Missing / Get That Back?
Dec 15, 2010
I have been a BSD guy for years, but I am now shifting over to CentOS for my first server build.
So far so good, all has been relatively painless and in fact a heck of a lot simpler than I anticipated!
Everything seems to have gone ok except a small problem with Bind. At some point during setup, I accidentally ran "yum remove bind-chroot".
When I tried to run "yum install bind-chroot" I got told "No package bind-chroot available" which was odd.
Anyway, I managed to find the rpm for bind-chroot and installed it that way. Now I see that there is a bind update available
Unfortunately the rpm I installed now has a dependency for the current version of bind which I can see being a headache everytime bind needs updating.
So, can anyone help me get back bind-chroot the proper way? code...

recently we decided to make our own panel (like Plesk or cPanel) but for Ubuntu and it will be licenced under GPL (like any other professional sofware).want to make a panel not only that fits our needs but also the needs of other system administrators and domain owners. We researched other panels and found out that non of them has security/look/ease of use in one package. Bad codig is another problem found in other panels.I made a short overwiev of what I think we have to have in the beginning.I Security :1. Completely chroot enviornoment where every single service is in chroot mode (bind,mysql, postfix, .... )2. Easily managed IPtables trough web-based interface. 3. Coding rules has to be strict.
II Software selection :
1. MTA - Postfix
2. POP - dovecot

I have just installed Fedora 14 on a machine which already has Windows XP on one hard drive and Ubuntu 10.10 on another. Fedora was supposed to be installed alongside Ubuntu
The installation appeared to be successful in that the process came to a natural end and I was told to reboot. However on rebooting I found that the boot menu did not contain an option to choose Fedora and was the same as it had been before I installed Fedora.
I opted to boot Ubuntu and then opened a terminal and typed 'sudo update-grub' and got a message to the effect that grub.conf was being created. When I rebooted again, there was still no sign of Fedora.
Is there any way of getting Fedora to boot? I am not sufficiently experienced in Linux to try anything else as the computer that I am using is not mine and I don't want to wreck the data of the owner. I did do 'sudo fdisk -l' whilst booted in Ubuntu and I saw that there are Linux partitions on both hard drives but I don't know how to tell which is Ubuntu and which is Fedora

Sorry, serious Ubuntu noob here. I was messing with the bar at the top (I think it's called the panel?) And now it's gone. I'm sure there must be someway to get it to show up again.

I'm new to Ubuntu and recently just upgraded from Karmic to Lucid (10.04). However after upgrade, Gnome seems misbehave every time I boot-up my machine.
On every boot, the following problem occur:-
1- Missing Title bar on all window.
2- Mouse pointer display as 'X'.
My current workaround was to set [Appearance Preference] > [Visual Effect] to 'EXTRA' on each boot.
I tried to set Visual Effect to 'NONE' before reboot but no luck. Reseting Gnome to default
Code:
rm -rf .gnome .gnome2 .gconf .gconfd .metacity
also not helpful.
Is there a way to fix it, say: reinstalling Compiz, Flushing FastBoot or the like.

I am completely new to linux and ubuntu. I burned the .iso of ubuntu to a DVD-R, and put it in my computer and rebooted it. It seemed to be working fine, but then the installation crashed, and I had to manually turn off my computer. So I took out the CD with ubuntu on it, and now my computer won't start! It says "NLDTR is missing. Press Ctrl+Alt+Del to restart." I can't do anything, because ubuntu never finished installing, and now my windows xp won't run either! It's really scary, if you could offer any advice or help at all, I would appreciate it so much. I'm completely new to this, I'm not even sure if I am posting in the right place.

I hear that "The working directory is not writable" is nothing to worry about and is just something that is complains about for no reason, but I can not decipher.
"Jul 8 22:10:49 localhost kernel: named[27073]: segfault at 00002aaaac0000d8 rip 00002aaaac0000d8 rsp 0000000040e78f58 error 15 "
I know segfault is having some memory problem at 00002aaaac0000d8 but does rip mean insertion point? What is rsp? Where do I find out what error 15 means?

I had centos 5-5 server with 6G of RAM and 4 core cpu 3GHZ i installed bind 9.7.1-p2 on my server with multi thread support there are a lot of dns requests on my server , about 2500 Packets/sec and 3Mbit UDP traffic but my server response week to most of them.
For example when i use nslookup or dig command to query Yahoo.com the response from server maybe deliver about 5 Sec or become timed out , but sometimes response time less than 1 sec!
I don't know why, perhaps kernel works week so i decided to do the following :
But the problem didn't solved
I previously had Freebsd with same version of bind and same configuration and everything worked fine.

I can't get the client server to authenticate to the openldap server. I can authenticate on the server itself though. I can su to, login and shh into the openldap server and become a ldap user. I just can't become an ldap user on the client.I didn't setup TLS/SSL. I can do that after I have it working. I'm using hashed passwords though. I don't have replication setup. I'm am tying to setup the most basic openldap environment then build from there. I have read the openldap section in the admin guide.
My setup at home.
Openldap server � light.deathnote.net -- 10.0.1.21
client server � vm-centos01.deathnote.net � 10.0.1.7 -- VM on virtualbox
Virtualbox host � L (OS MAC) � 10.0.1.2
router (apple airport extreme) / default gatway � 10.0.1.1
All computer can reach the internet and ping each other. When I installed centos I disabled SELinux.I used these guids to setup my openldap.
[URL]
Below I have included some output from the files I'm using with openldap.
[root@vm-centos01 ~]# tail /var/log/messages

I have setup two BIND9 servers as slaves for an internal Windows domain. I receive messages in my logs about a Windows server not being the master for the slave domain on BIND. I have placed the allow-notify statement in the global options section of named.conf, as well as setting the IP address in the masters section of the zone. I'm confused as to why I'm still getting this error message.
