My server keep crashing ever so often. For the last three days one random server die each days. How would I track down the problem to solve this.
I have around 18 Servers.
Running from ubuntu 9.10 to 10.4.
My servers are traffic and storage intensive,
I need to trace/track email activity in my ubuntu server, normal i use this command tail -f /var/log/mail/mail.log, more or less. But the problem i am facing is that it take a long time to go through the entire log as my server recieves thousands of emails per day. is the a code that i can use to search email in the log, for instance need to find perfectpol@mycompany.com in the mail log.
Secondly; if there is an email that is blocking others on the queue how can it be remove or forced to go the mailbox. or to view its contents in order to decide whether to remove it or not.
Had a problem that are said not arrival or that are delivered as late as a day and sometime 6hours.
how can I track a Dos and DDoS attack on a server . Does linux have any goiod known command line utilities and log files to us e in this way?
View 1 Replies View RelatedI am writing a client chat server program in java. The chat server is already written. I created the interface and I connected to the chat server. The server keeps sending protocol messages to whom ever is connected, also it keeps sending specific protocol every 10 sec to check if user is still online.My problem is when I connect from my interface to the chat server, the program gets stuck, I can not press any other button because after connection my program keeps receiving commands from server(I have a method to keep reading after connection). How can I keep track of messages sent from server and not get stuck i.e press other buttons or type in the interface?
View 2 Replies View RelatedI'm running an OpenSuse 11.2 box at home which updates a mysql database 4 times a day then posts 34Mb to my website. It's exactly the same amount of data each time, and my scripts*TRUNCATEs then rewrites the database with the latest data - so the database size remains the same.
There's a problem (I think with the script) however which means that everytime the script runs, approximately 34Mb of space on my hard disk is mysteriously taken up. I'll have to get that script fixed...
I can't, however find the files which are eating up my diskspace at the rate of 140Mb per day. I've done various searches (mainly with Dolphin) including hidden files immediately after running my flaky script and looking for any files created/modified in the previous few minutes when the 34Mb has disappeared.
There are LOTS of files in /proc (which I don't think is actually on my HD right?) and also in /var. There's nothing much in /tmp (on a separate partition) or any log files that I can see. The box has been running this script daily for the last 6 weeks so I'm hoping there's a load of files somewhere I can get rid of, then fix my script.
i found this video, and i really want to do the same. *newbie needs to learn [URL]...my question is, what need to be installed and how?
is there any specific configuration to make it works?
and will it work if i want to connect from Ubuntu to Fedora ?
I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'

I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
I own a rather large website/forum devoted to Scuba utilizing vBulletin. The problem is that its become INCREDIBLY slow as of late. I have three Ubuntu web servers under a single Ubuntu load balancer and they draw from a CentOS 5 DB server running MYSQL. Here are my concerns:
-I am thinking that they are all 32 bit rather than 64 bit.
-I am thinking that the problem is an IO issue.

View 2 Replies View RelatedI have an mp4 video which includes a 5.1 audio stream, while I only have stereo speakers from my computer. It is hooked up to my receiver through the audio out (headphone) jack from the back of the machine. Anyway, I have a stereo audio stream for the video, but I can't figure out how to add the mp4a stream to the mp4.
I have checked out avidemux, but it doesn't seem to handle mp4a files. I don't want to transcribe the video, simply add the audio to the mp4 container. Does anyone know how to accomplish this in Ubuntu?
It seems that the mp4a is us encoded as AAC.
Some mp3 songs will have track informations like website address etc etc..How to remove those information...?
View 2 Replies View RelatedI'm sure this is simple but I haven't a clue how to do it other than System Monitor, which only displays for the total uptime.
I want to see what my total network data use is in Bytes (GB, MB, or KB) downloaded/uploaded for the month or any given date range.
Rationale is I want to use wireless tethering from my phone to replace my broadband connection at home. At the moment my phone contract gives me unlimited data access, however if I were to sign a new contract today this would drop to 2 GB a month with hefty overage charges.
I would like to have a way to keep track of my working hours easily.
Insert arrival and finish times and have the difference in decimal. For example, if I start at 8:00 and finish at 9:30, 1.5 should be added.
I tried to do this with Calc but couldn't figure it out. I set one column to have entrance time, another one to have exit time and a third one with the difference("=B2-C2"). The result is in a timestamp format and not decimal. If I use another cell to say something like HOURS(D2) it rounds the number rather than give a decimal(would give 9 for 9:20:00).
EDIT: solved by doing =24*(B2-C2)
Is there an add-on for Rhythmbox which recognizes track info from the sound of the track like the shazam app?

View 9 Replies View RelatedI'm using LibreOffice 3.3.2 to open a document I received through work. The document is from MS Word in .doc format and has some track changes. I started using Libre Office to track my changes to the document but the only format I can save it in and retain my changes is .odt which is fine for me. However I would like to return this in .doc format.
It seems odd that LibreOffice happily opens a document with track changes but cannot save them back in that format.
Am I doing something wrong? I am using Edit>Changes>Record and then File>Save As.

I've installed Ubuntu 10.04 and it works like a charm, pretty much all over. However I seem to have problems using my M-Audio Fast Track Pro with all four channels - primarily when using Mixxx. I hate to switch between Win7 and Ubuntu just for the use of my VCI-100. Is there a way to have Fast Track Pro work? I tried almost any of the solutions found around here - but i simply cannot get it to work.
