Ubuntu :: Dbus - Daemon Consuming 50% Memory
May 4, 2010I've just upgraded to 10.04. I love it. I've been running dark themes for a long time and this upgrade merged seamlessly with my setup.There is a nasty problem that I've noticed on only my desktop box (laptop is fine, also upgraded to 10.04). The dbus-daemon is hogging approximately 50% of my cpu cycles. Is there a way to limit this? I'm watching this via the System Monitor and the % CPU. My laptop registers its dbus-daemon % CPU as 0.

Feb 7, 2011There is squid 3.1.8 on a Fedora 12 server with 2 GB of RAM. It is used for sharing the Internet for approximatively 80 PC's. The problem is that it is really a memory hog, when enabling delay pools. I am using the following configuration for the memory pools:
Code:
delay_pools 1
delay_class 1 2
delay_access 1 allow drumuri
[code]....
There are moments when the squid process uses approximatively all the RAM and goes into swapping. After that I restart it, it goes well for a while and again eats up all the memory. On the Internet it says that Squid uses a lot of memory, but should it use 2 GB of memory, even if all 80 people are online at the same time?
Fedora :: /dev/shm - 224 Mbyte Ramdisk That Is Consuming 224 Mbytes Of System Memory Whether Or Not Use It
Dec 5, 2009I just noticed this in my "df" output:
[Code]...
There's an entry in /etc/fstab which mounts this automatically. If I interpret that correctly, that's a 224 mbyte ramdisk that is consuming 224 mbytes of system memory whether or not I use it. Is that correct? If so, will anything break if I unmount it and delete it from /etc/fstab? Do programs typically depend on it? I'd like to reclaim the system memory (low DRAM machine) for other uses.
Server :: Bind Memory Usage Keeps Increasing?
Jun 14, 2011I'm running a recursive DNS server on Ubuntu Server 10.04 64bits and Bind 9.7.0-p1 and having issues with memory usage. The named process memory usage keeps increasing from about 500Mb to 4Gig inside of a couple of weeks. If I don't restart Bind in the mean time the swap fills and performance gets very bad.

Mar 18, 2010Have basic LAMP setup on 9.10 box. I want to have a publicly accessible website AND I want to have phpmyadmin available. The only thing is I would rather not have the phpmyadmin interface available on the internet. I usually open a ssh port forwarded tunnel when I need to use phpmyadmin on this server. I want to add a directive to make phpmyadmin bind only on localhost. I have found the phpmyadmin config file in /etc/apache2/conf.d
phpmyadmin.conf -> ../../phpmyadmin/apache.conf
I have tried adding some LISTEN directives, but apache does not like my directives-- I am obviously not doing it right. I have looked for a bit on the internet and can't find out how to disable external access to a configured site in Apache.

From some tutorials I have read, I see I need to recompile it to enable its SQL support.
But when I do it that way, I won't get any security updates, won't I?
So... Is there any bind server with SQL support in the repositories ? For that I don't have to worry about security updates...

Ubuntu Servers :: Bind Slave Tries To Update From Gateway?
Jan 21, 2011I have 2 nameservers setup, a master and a slave. when I first setup the slave, I restarted bind9 and all of the zone records propagated just fine. Today, I updated one of the records on the master (no problems), but when I restarted bind9 on the slave it gave me a FAILED message. I checked the log and it was trying to receive notify's from my gateway address (192.168.10.1), and got "Failed to update from non-master". I did some research and found several people having a similar problem, but their slaves were trying to update from their own IP, not from the gateway IP. I tried their solution (allow-notify { 192.168.10.1; }) but all that did was allow the slave to restart bind without errors, it still doesn't update the records. It says "zone is up to date" but it's not.
IP's are:
Gateway 192.168.10.1
Master 192.168.10.200
Slave 192.168.10.201
All of my zone records have the masters statement set to 192.168.10.200 I don't know how it even came up with the gateway address
Ubuntu Servers :: 10.10 - Bind 9 Not Accepting DNS Client Queries
Feb 13, 2011However I just built a 10.10 server, installed webmin, vmware, and the server is working perfectly. I configured my bind 9 server using the latest webmin and on the server everything resolves perfectly to both the internet and lan. I have it set to 127.0.0.1, the server ip address is 10.1.50.25. However, it will not accept dns client queries in which they cannot resolve to the lan or internet. I have the dhcp giving out the dns server 10.1.50.25. NSLOOKUPS from the client show query refused. I know there has to be some setting or config that will allow clients to query but I am not able to locate it, and I am not totally knowledgeable of named.conf and been all through the webmin module and configuration settings.

Aug 12, 2009I'm trying to get BIND running on one of our Fedora 10 servers, since we've had some issues with the DNS from our service provider.

I'm getting the following errors when I do service named start:

May 21, 2010I'm setting up an ftp server with lucid server.

My guess is mount bind, but I'm not that familiar with the internal workings of linux and vsftpd (plus for symlinks I wouldn't have to change/create any scripts, just create them once...),

Dec 8, 2010I have 2 servers operating on my home network. One server hosts Bind9 and a few web sites. The other is an Ubuntu repo mirror that I recently configured (10.1.10.26).

Fedora Servers :: Installing A DNS Server On 13 Running Bind

Now the first one contains bind utils the second one is for running DNS in a chroot env and the last one is a bind with some DB backend.

Software :: Zone Transfers For Load-balanced BIND Servers?
May 13, 2010I am planning to implement hardware load-balanced DNS servers. There will be one master and three slaves in the server farm. I will have two virtual servers associated with the server farm that will be listed as external nameservers for our domain.
BIND uses the list of NS records to determine the servers that need zone transfers. The zone NS records will not be the addresses of any of the real servers. How do I tell the master to do zone transfers to the real slave servers?
