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

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

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

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.

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

Hey List; I have no experience with software RAIDs; at work we only use hardware RAIDs and I'm looking to implement, probably a RAID 5 set up at home for a media server however I have a few questions; I have three 1TB drives in various places; one is inside a USB caddy, one is inside my PC and in is inside my existing media centre. Is it possible to add these three drives to another one to

Hi List, I suppose this isn't strictly CentOS but I'm talking about some 5.5 servers so I thought someone else here may have had the same issues; We power on servers at night via IPMI and shut them down the same way for automation. The problem I'm facing is that the servers are shutdown in about 2 seconds. IPMI provides remote access to the power features as we know so I don't

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

Hi, I am experiencing a weird issue with my MV-372. Mobile1 & Mobile2 are both registered to my asterisk server, I am able to use them for outgoing call with no problem, but when I call the sims in my gateway, they are routed to the right context/extension/priority, but as soon as I hangup, the sim unregistered from asterisk and tries to register with my the callerid of the last incoming

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,

Hi, I want to clone my hardisk containing the centos-5.3 OS and its swap region on to new raw hardisk via network either through ssh, tftp or ftp. How do i do that ?

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"

Hi, I lost my mdadm.conf (and /proc/mdadm shows nothing useful) and I'd like to mount the filesystem again. So I've booted using rescue but I was wondering if I can do a command like this safely (i.e without losing the data previously stored). mdadm -C /dev/md0 --level=raid0 --raid-devices=2 /dev/sda1 /dev/sdb1 Where of course the raid devices and the /dev/x are the correct ones

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

Hey guys, I'm a bit of a beginner (understatement!) with shell scripting and seek help! I am setting up our new squid proxy. Its working a treat and squidGuard is the icing on the cake. But, I am trying to write a shell script to search through our black list category's for squidGuard and remove the parsed value; Scenario: /some/directory/where/blacklist/is/stored contains about 40-50
