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

I have some questions on how I can perform the following actions from the terminal in CentOS 5.5 final. My Google searches aren't helping and I keep seeing references to the command 'useradd' but this isn't present on my box; -How to add a new user? $ useradd -bash: useradd: command not found (This is the same for my normal user and when logged in as root) -How to set/change an

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

I'm stuck trying to work this one out and my Google skills are apparently lacking today. This is a test bash script; #!/bin/bash do something | tee a.log if [ $? -ne 0]; then echo broken fi The problem with this script is $? contains the exit value of the tee command, but I want to check the exit value of whatever command I put in place of 'do something'. How can I achieve this

Hi List, We have a CentOS VPS running a web site in a DC far away. The chap that dev's this site told me he couldn't SFTP in yesterday, his password was being rejected (I went to his desk to confirm and saw it was telling him the password was incorrect but neither him nor me had changed it and we are the only two with access to this VPS). So I logged in as root and reset his password, be

Hi List :) So, I have a folder1, its owner is user1 who has r+w on the folder. User2 is the group owner who only has read access (when I say user2, I mean the group called user2, because when you make a new user the OS can make them their own group). You can see these permissions below: [user2 at host test]$ ls -l drw-r----- 3 user1 user2 28 Nov 2 16:17 folder1 How ever user2 can not

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

So I went to System > Administration > Server Settings > Samba and added a folder to share and initially set it to guest access to get things going. I couldn't access this one and only share on this server with guest access from either my Windows laptop (XP Pro SP3) or a Leopard server (10.5.8) so I changed the settings to use user authentication and added my local user details

Hi All, I am looking for a way to troubleshoot issues with TDM (E1) trunks with a provider. Currently with SIP trunks I am using tcpdump to perform packet captures between our gateways and the SIP providers IPs, capturing traffic on all ports, to include both the SIP messages and the RTP stream. How can I achieve a similar result on TDM links connected to TDM cards in Asterisk servers, where by

Shadies and Mentlemen; I am trying to be green and put our backup servers to sleep during the day and have them wake on LAN and fire back up at night for our nightly backups as "sleep" is a sort of low power usage mode. (At this point I would be curious to know the different levels of sleep, what can I achieve? Does my server just drop into a low power state, or can I stop the hard

Howdy all, Does anyone know of a niffty CLI tool for Linux that can take a PCAP file that was created on a SIP PBX for example, and then dump the payload of the various RTP streams in there into seperate files so I can listen to them? I can go this graphically with Wireshark, but I'd like to script it for automation. Cheers, James.

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? (Obviously the OS comes into play here a bit

Hi Everybody :) I'm sorry if this is unwanted noise but I'm struggling to find the answer to what is probably a ridiculously simply problem. Setup vncserver but it likes to run as a user (reading parameters from ~/.vnc/xstartup of the user the process runs as). When I start vncserver and connect in I am dropped into a running copy of X of that users desktop, how can I instead have it

Hey Listees, I have a question (hopefully quite simple) about the system V init scripts in /etc/init.d. I have an app installed and for some reason it had no system V init script. It has been installed a long while now so I can't quite remember whats going on but basically I remember I wrote the init script my self and the app is enabled as a service which chkconfig to run at system levels 3,

Does anyone know if using unequal drives in a RAID 0 is possible? I was looking to set up a software stripe but if I have two volumes of unequal size I wish to stripe over, will the OS try and work around this by say only using as much space as is available on the smallest drive or is there anyway it will use all of both drives? Does it have to be a perfect block/byte balance across drives?

The glitching occurs even with only 1 listener. It seems to repair itself for a while if

Hey Guys n Gals; I have some arrays that I can't seem to expand correctly (if that's the correct word?), imagine the following example: #!/bin/bash myArray=("First" "Second" "Third") First=("Monday" "Tuesdays" "Wednesday") Second=("One" "Two" "Three") Third=("A" "B"

Hello! I'm trying to install Centos 6.4 64 bit on this Xserve: http://www.everymac.com/systems/apple/xserve/specs/xserve-intel-xeon-2.8-eight-core-specs.html I got a bootloader from: http://blog.christophersmart.com/2009/07/23/linux-on-an-apple-xserve-efi-only-machine/ as none of the official Centos releases (full, minimal, network 64 bit) boot on this machine. They all crash when loading

I have a Dell PowerEdge SC1425 server and I installed Xen with Debian on it. When I plug the power in, I''m able to access the server via IPMI. After I start the machine, IPMI is still available. But when I command a shutdown on dom0, it will go down and say "Power down", stay there and IPMI is not available anymore. Only after I remove the power cord and replug it is the
