running ps -ef I get a number of processes back.. lets take the one below..
apache 10862 2845 0 16:02 ? 00:00:00 /usr/sbin/httpd
It is clearly a webpage that is being used..How do I look deeper into the process '10862' and see what webpage is being used?
I've been using GPG keys for about a year now to send encrypted emails to family. But now I want to try and understand more, mainly on signing keys. I've read a ton of stuff, but not fully grasping the concept. So I thought I'd check my understanding people here. Please let me know if I'm wrong on something.
Signing keys seems to be just signing someone else's public key with my private(public??) key. Does that mean I don't sign my own keys? Or should I? There seem to be lots of keyservers out there, mainly I keep hearing about the MIT one and the ubuntu keyserver. Does it matter where I upload my public key? Somewhere I read that once you upload it once, it will slowly make its way to other servers. How is that possible. If someone signs my key on one server, will that also get pushed to other servers?
I'm dual booting with Windows 7 and would like to have my windows 7 user folder mount when I boot.
After some looking around I edited /etc/fstab to add the following line:
This works. But it mounts the windows partition from the root level. I'd like to just mount C:UsersFHSM (/Users/FSHM) to /mnt/windows.
I'm trying to get it so that when I click on the windows drive I get my windows user folder instead of having to click through from C: to get to it.
I'm the only user on this system but if I created a second windows user would my home folder mount for that person too or does setting the user ID prevent that from happening?

View 1 Replies View RelatedI am trying to install CentOS 5.2 on an HP rp5700 desktop unit. These units were originally sold as a Point of Sales unit I believe, but HP also markets it as a high life cycle server for SMB market.I tried to load CentOS on this unit via CD (created from downloaded ISO of course). It presents the initial CentOS banner page and waits for the obligatory "enter" to continue. It begins the boot process up to discovering the PCI stuff and just locks up, no response. I have to power down to restart.Since this does not even get to the point of installing. I am at a loss what to do next. Has anyone had a similar issue with other PCs.The boot stops at the lineACPI: PCI Root Bridge [PCI0] (0000:00)

This is a long shot but I'm looking for a way to assign an IP to a specific location or process. I'm running a server for a small indie game that I liked, I intend on running as many gameservers as possible from this server, however I hit a problem: The game limits servers to 4 per IP address, after this the servers no longer are able to connect to the main server and therefore be used. My server has enough IPs to run many gameservers, but I'm unable to work this out.
I need to assign either an IP address to a process or folder, right now I have it set up like so: (assuming 1.1.1.1 = server IP)
/gameservers/server1/program < assigned to 1.1.1.1
/gameservers/server2/program < assigned to 1.1.1.1
/gameservers/server3/program < assigned to 1.1.1.1
/gameservers/server4/program < assigned to 1.1.1.1
[Code]....
I do not have access to modifying the core program, it runs in Java. How would I go about doing this, if indeed possible? I need to either apply the selected IP to a folder or process without changing the actual program.
I have a process that seems to be unexpectadly quitting. Checking the messages log I could not find anything out of the ordinary. Would anyone here know how to make a process unkillable or lock a process somehow? I read information on doing this by making a looped iso, however the process im starting requires to be able to read/write to the files in the iso so this is not going to work. For now I just niced the process to top priority but I dont really think that will work. This process is a voice server so I dont want people getting discouraged that the server will not stay up and decide not to use the free service im offering.
Would anyone else have any insight as to what I can do? Im not new to linux but im not familiar enough with how every command is used, so if at all possible please give me the commands that need to be executed.
I'm trying to check how much ram memmory and CPU is a particular process consuming, i have checked free -m and top but is not esay to undesrtand the output from CPU

It's hard ot understan the output from top, to many columns and MAY process, not easy to check the process i want to monitor

I have CentOS installed on one of my machnce, its my PHP development server. I also wanted to run a Minecraft server on it. I would like to skip autostart with init.d thing and be able to control it's run manually, but remotely. Thing is, when i log via putty to server and start server the server output is in terminal. When I close puty, ran application closes also. So I need to have putty window ran all the time.
So, since many programs can be run as background task (like httpd). Is there a way to log via putty. Start application and send it to process... log out of putty ( and application doesn't shut down with putty)?
Also, would be nice if I was possible to log to putty and switch to that application, so i could see server output, info and Issue commands. Basically, I want to start a service and be able to manage it via putty. and not close it when i terminate putty.
PS: I have installed Windows on CentOS server. Is there a way to issue a system start without loading whole GUI thing? When I was installing it I thought it would be easier to manage it with GUI, but now loading it only eats system resources and i unplugged monitor and mouse nad manage it only from Putty
I have tried top and PS command but i am not able to find the RAM used by each process.top command says that 240MB RAM used but the Memory shows 0% for all the processes, same with ps. i want to know which process consumes all 240MB RAM.Is there any command which / script which can sort the running process in oder of increasing RAM usage so that i can see. Also i find it very hard to read bytes and KB. Is there any to way to chnage those units to MB

View 1 Replies View RelatedMy centos machine suddenly stuck, the hdd LED flashes constantly, and the system reacts to all my operations very slow. I even cannot log in to a native terminal (always timeout). I had no choice, I pressed the power button. Reboot once failed. The system failed to find mount points.

I'm running CentOS-plus V5.5.CDs automount fine, but DVDs don't. I can, however, mount DVDs manually.I have scoured the web without seeing a solution. Its also clear that the software or process used by the OS to automount a DVD, has changed in the last few CentOS versions. So now I would like to ask:,In V5.5, what is the current process or software used by the OS for automatically mounting media such as a CD or DVD?What configuration files are involved that allow a CD to be mounted, and what entry(ies) would be needed to automount a DVD?

My program is creating 4 threads per transaction. Threads doing nothing but simply sleeping.
Now, when transaction ends, I want to wake up all the threads from sleeping. For this I am using pthread_kill() to wake up the threads using signal SIGUSR2.
Problem raises when I put more transactions(eg. 100 trans). My process gets hangup.
I'm have some desktop computers sharing my Centos 5 server diskpace through NFS. From time to time, without any warning, lockd bugs and all the users that are using GTK applications like Firefox,Gnome.get stuck.
My first atempt is to restart the NFS, but locked files persist because I can kill the lockd pid process, even using root account , I suppose this is because it's a kernel process. Here is the message error I get when restarting NFS matrix kernel: lockd_down: lockd failed to exit, clearing pid
We had servers that worked fine for years. After updated them to the latest version of CentOS (5.2 with latest updates), they keeps on hanging when being scanned by PCI Verdors (a Credit Card security standard). Basically, the scan causes httpd process to eat up all memory, and the server becomes unresponsive. Normal operations resume after the scan stops for 5, 10 minutes. Output from top looks like the following:
Mem: 1018988k total, 1007168k used, 11820k free, 432k buffers
