Fedora Networking :: Command Line And Did A Couple Of Chkconfig Things And Entered Ip Address?
Jan 8, 2010F10 trying to key in static ip address. Have followed guidelines on turningoff NetworkManager and turning on network. i went to command line and did a couple of chkconfig things and entered ip address, with subnet. when i do ip addr show i see under eth0 inet 192.168.3.11/32 which is 255.255.255.0, i'm pretty sure. i do not see gateway. when i go to system/network get prompted to log into root, network config window opens. icheck eth0 and the subnet mask is 192.168.3.1, the gateway, which is in correctly, in the gateway slot, as well. i still can not ping to from my xp based multihomed router.

Programming :: Name Of Formula N Things Out Of Collection Of M Things
Jul 22, 2011I'm working through some problems in a beginners programming book. The author mentions a formula for calculating the number of ways of picking out n things from a collection of m of them:
Code:
/ m m!
| | = -----------
n / n! (m-n)!
But he does not give a name for the formula. Does anyone happen to know what it is called? I need to do some related research.
Server :: Omit A Couple Of Update Packages?
Jan 26, 2011I have a server running Ubuntu 10.04 server - no gui. In the list of updates today I see plymouth and plymouth-theme-ubuntu-text. Plymouth is a gui application (and not a very good one from what I recall from 10.04 alpha and beta testing days). So I don't understand why I would need it on a box with no gui.
If I use Webmin 1.530 to attempt the updates I unselect the two plymouth packages and then click Update Selected Packages. The list on the Update Packages confirmation page shows the two plymouth packages. I can unselect other packages and they do not appear on the confirmation page.
If I use apt-get upgrade I am again presented with a list containing the plymouth packages. Nothing in the apt-get man page jumps out at me as a way around all or nothing. I guess I could manually install the other 8 updates and not do the plymouth ones. I fear that they will keep appearing on the updates list each time.
Server :: Process Of Setting Up A Couple Of Virtual Servers In A Cloud Environment?
Mar 17, 2011I am in the process of setting up a couple of virtual servers in a cloud environment. I am currently working on my application server (Server 1) and am stuck on the creation of my ruleset for this server.
I need to allow SSH, FTP, HTTP, HTTPS, and PING on this server. This server will also need to be able to talk with a couple of database servers as well as a memcache server (all internally within my cloud environment)
I have been reading on iptables, since I have never messed with them before, and have come up with the ruleset I will paste below. I have taken other steps to secure my server...changing ssh port, not allowing root to login via ssh without logging in as a user, turning off unnecessary daemons, editing my hosts allow/deny files, just to name a few.
I am a newbie to iptables, so I would love a bit of helpful advice, criticism, and even a good explanation why I should add or remove or edit something. I really want to know the how AND the why!

Oct 18, 2010I'm looking for an easy way to check if some server is down, and then act upon it. This check needs to be done from the backup-server. So if the backup-server thinks the production server is down, then in some bash script I want to execute a rule.
My question: what is an easy way to check another server ?
1. I know about Nagios. It's great, but to large to use here.
2. I could ping the server, put a ping that fails does not necessarily mean the server is down.

View 8 Replies View RelatedUbuntu :: Use Server To Compile And Run Heavy Things And Control It With Another Machine
Mar 20, 2011Can I run/compile programs on my remote server and control it using LAN? How do I do it?
Long Version:
I have a spare computer here. It's rather powerful for my daily needs (Athlon X2 6000) and I want to set it as my HTPC/Server. Don't worry about HTPC, it got Digital Audio output and a Radeon HD3200 with HDMI out, outputs 1080p pretty well under Windows (I'll setup it for Ubuntu when I get everything straight). So, I thought "Well, I think it's going to be overkill to let such machine as a HTPC only. I'll use it as a server too!". So far so good, but I don't know anything about servers or such. I would like it, as a server, to compile huge programs and handle big compressions (I'm actually with a Celeron ULV 1.2GHz netbook for such tasks, takes ages). Also, it would be pretty nice if I could control the server with my netbook. Like, Start/Stop music/movies with my netbook, control the Boxee/XBMC (Media Players) with the netbook, and, if possible, control its mouse.
Btw, will Ubuntu 10.10 support Hardware Acceleration for ATI Radeon HD3200? Over Windows' DXVA it works OK.
General :: Get The Physical Memory Used By A Couple Of Processes?
Sep 3, 2010I am doing a test to get the memory used by apache`s apache2 processes. I used a script to get VmSize and VmRss from /proc/pid/status, and loop through that to get the sum of VmSize and VmRss of all the apache2 processes.
I found the VmSize (about 4GB) and VmRss (about 3.4GB) are much larger than the physical memory (1GB) when apache server was saturated. It was said because of the multi-counted libiraries size used by many processes simultaneously. Then , how to get the physical memory used by apache2 processes? Or how to get a more reasonable memory data?

Mar 24, 2010How Linux would run NT in a VM, and the correct definition of how things work. Now I now about nothing about of Linux, though I have installed it a few times, but never really worked with it. I have been using MS products for 15 Plus years and have a pretty good understanding of how things work. I do not claim to be any expert. Some Idea of what I am inquiring: Now, how does the Linux Kernel handle the NT Kernel? Are processes/threads in cpu separated for each Kernel? How would interrupt requests be handled? How is Memory and Disk Management handled? Then obviously how would Device Management be handled as well?
