occasional glitching when playing
Hello list I'm running Icecast 2.3.2. Every few seconds, streams are interrupted by a noticeable glitching or popping sound. It sounds like it's being caused by a buffering or latency problem but I'm not sure how to fix it. If the listener re-connects to the stream it stops the glitching for a few minutes, but eventually it returns. Glitching is also appearing in the dumpfiles

Simple routing question
We use a dual homed CentOS-6.3 host for our Internet gateway router. Its internal nic (eth1) is configured such that the address 192.168.0.1 is one of its aliases. # cat /etc/sysconfig/network-scripts/ifcfg-eth1:192BOOTPROTO=none BROADCAST=192.168.255.255 DEVICE=eth1:192 IPADDR=192.168.0.1 IPV6INIT=no MTU="" NAME="LAN - Non-routable" NETMASK=255.255.0.0 NETWORK=192.168.0.0

General Server Hardware Question
Hey List, How do people measure how many listeners they can have on a single NIC card? A 1Gig Ethernet NIC card maybe able in terms of bandwidth to serve 31,250 listeners at 32Kbps (not including overheads etc, just a flat calculation) but there is no way the NIC card its self could handle 31k concurrent connections to 31k different IPs on 31K ports?

what updates /etc/localtime?
I see in CentOS 7 that /etc/localtime is a symlink (which seems sensible...) but in earlier versions it is a copy of some file from under /usr/share/zoneinfo. rpm -q --scripts tzdata does not show any postinstall script, so in the non-symlink versions, how does the copied /etc/localtime file get updated with new zone data? -- Les Mikesell lesmikesell at gmail.com

ext4?
Listee's... I have a 5.5 box and I have formatted a partition as ext4 however I can't mount it, the mount command is telling me its an unknown file system type. fsck tells me the partition is a clean ext4 partition but I can't mount it. Some reasearch has lead me to believe the problem is that ext4 isn't enabled in the kernel by default in 5.5 (this was originally a 5.2 box that

Rsync Directories
Hey List, I am setting up an rsync daemon (not something I normally do, I normally use rsync over ssh but I'm trying to set up an rsync server and have clients sync their local directories with what is on the server) and I am wondering about the directory entries within the rsyncd.conf. You can add entries in the rsyncd.conf file for directories such as; [Example] comment = "My example

DNS master slave update issue
I have a situation where the slave nameservers for a zone are being notified by the master that a change has occurred but the slaves are not requesting a zone file transfer in consequence. Is there some special flag or directive that I must set somewhere in order for this activity to be automatic upon receipt of such notices? All systems involved are running DNS 9.2.4. Regards, Jim --

Long tar -x: Box Shuts Down
My Centos 5.2 box shuts itself down during a long tar -x. There is plenty of disk available. This is new; it worked in the past. Any suggestions? Thanks, Mike.

KVM console?
I finally got access to some machines with more resources than the free VMware ESXi license allows which pushed me into trying kvm instead. Seems capable enough for what I need and can even import and run the existing vmdk images I already have. But, I have some questions about accessing the virt-manager console remotely for initial configuration, etc.. Normally I use freenx for remote GUI

Make Raid1 2nd disk bootable?
On earlier versions of Centos, I could boot the install CD in rescue mode, let it find and mount the installed system on the HD even when it was just one disk of RAID1 partitions (type=FD). When booting from the centos5 disk the attempt find the system gives a box that says 'You don't have any Linux partitions'. At the bottom of the screen there is something that says:

Lost root access
So on a virtual server the root password was no longer working (as in I couldn't ssh in anymore). Only I and one other know it and neither of us have changed it. No other account had the correct privileges to correct this so I'm wondering, if I had mounted that vdi as a secondary device on another VM, browsed the file system and delete /etc/shadow would this have wiped all users passwords
