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

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

Hello guys, Did anyone noticed how green CentOS 6 is compared to the previous release? I've been running a couple of "CentOS 6" VMs (on our vSphere environment) for the last couple of weeks and noticed a BIG difference when it comes to CPU usage when the VM is completely idle. I would like to share what I've seen in our environment: PfSense 2.0 (FreeBSD) VM: 40 Mhz CentOS

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

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

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

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,

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 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, all These days, I am interested in green IT area for low power OS So, I have a question about it. Is there any good idea or comments about power management related with cgroup based resource management? I have no idea about that, but it seems to be possible to find a good concept. And I hope so Is it some strange question? ^^ Regards, Dong-Jae Kang

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 list, I have several crontabs set up to run at night and I'm not convinced they are running but of course, I'm not here to see for sure! The crontabs are like the following example; 30 20 * * * sh /home/a_user/nightlyscrips/nightly_script_1 > /home/a_user/nightlyscripts/`date +%d-%m-%Y--%H-%M-%S`.log However, if this would have successfully ran last night I would surely expect to

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

Hi All, I have a win2k3 server that its backing up to a CentOS 5.3 server. On the Win2k3 machine I plan to have rsync back up nightly to the CentOS server through ssh. The command I am using is as follows: rsync -vrPtz -e ssh myuser at myserver:/remote/backup/folder/ /local/backup/folder/ This all works great for the inital test except its prompts me for a password for "myuser" (as

Anyone out there have the AudioCodes MP-108 working with Asterisk? I am able to get the channels to registers with Asterisk, but anytime I try and send a call I receive these error messages: Jul 6 15:12:10 DEBUG[1133742896]: chan_sip.c:771 __sip_ack: Stopping retransmission on '117801284512845hUxv-9991110061--17708185305@63.201.117.76' of Response 20587: Found Jul 6 15:12:10

Hi, I have quite a few low-end development/test servers running continuously and I would like to better manage their power consumption. I have found interesting information on how to perform CPU scaling (e.g. [1] or [2]). But I cannot find if there is a way to (software) monitor power consumption on CentOS (or other such data like CPU temperature, fan speed etc.). What I read so far is that
