I am running Montavista distribution. I have an Apache server running in my machine. Now I want to know how many clients are connected to the Apache server and what are the process ids for those sessions. What is the command to do that?
View 5 RepliesI've always wondered whether my process kills when I am in the process of doing something during my ssh session. For instance, I ssh from my local box to dev-formbox and did an scp transfer to another remote host. All of the sudden, I lost ssh connectivity on my local box due to network issue. Will the scp process (or any of my process that I am currently doing) kill also once I loose the ssh session?

I partitioned my hd (canibalized from an acquaintance's emachine and connected it to my desktop (1G ram, 2Ghz processor). Booted from disk 1 and fomatted the 80G HD for 2 partitions of linuxswapable at 2G apeice and 2 partitions of bootable linux. (Because i want to try another distro later). I ran the setup installing most everything and all seemed to go well. After i exited setup and restarted, it identifed the cd/hd as normal and then went into some sort of recovery mode with the emachine logo call pcangel, after which it tells me.

View 4 Replies View RelatedI have a script that calls other scripts/commands which may or may not spawn other process. From my understanding, when I do a ps -ef, the highest numbered process ID is supposed to be the parent ID of all the other related child processes, is this correct? In most or all circumstances, I do a ps -ef | grep <processid> of my script and anything that spawns off that process IDs I assumed are the child processes of my script. If I want to terminate my script and all other child processes, then I kill the parent ID which is the highest numbered PID and this will subsequently kill all other child process IDs, is this correct?
Now, my question is whether there is any quick way of showing what are the child processes of a parent ID instead of what am currently doing now which is visually checking which one is the parent ID and "assuming" that the highest numbered PID is the parent ID of all the other processes. Below is a sample output of running ps -ef | grep exp | grep -v grep. I assume from the output below that the parent process/ID is PID 11322, is that correct?
Code:
oracle 11154 11153 0 21:20 ? 00:00:00 /bin/sh -c (. ~oracle/.profile; /bin/ksh /usr/local/oracle/scripts/expdp_o

To pre-empt some obvious solutions; I don't wish to use VNC, the lag drives me nuts, and I'd like to keep my gnome session running on the client machine if possible. If it's not possible, that's fine; it just seems like there'd be a way to do it?
I was working normally and the GUI just failed, all I could still see were any open windows. I rebooted the machine from tty1 and now I can't login anymore under my normal user accounts.
I enter my credentials, it appears to login, and immediately goes back to the login screen. Note that under tty1 I can still login with my user account and do everything.
I can still login with root in the gui.

I have ubuntu 10.04 & I telnet to windows vista. Even if I create a hidden process [URL].. from batch file . It seems the process gets killed when I end connection at port 23 to host. Maybe , the hidden process created is still child of current telnet session so tree is killed as session ends. Is there a way to keep process running even after telnet session has ended ?
View 6 Replies View RelatedI am currently struggling with one of my tasks.I was asked to find a way how to determine how much time an _already running_ process is spending in user and kernel space.E.G. <some tool> <pid>[Control] + [c]<pid> spent 12.1 seconds in user and 1.52 seconds in kernel space.Does something like this exist? Basically I guess I am looking for something similar to time, except that the process is already running.So..a) Is there a tool which fulfills this task?b) Is there a way to write your own software which does the job? Is it even possible to code something I am looking for?I recently found strace -c -p <pid>, but well, this is not exactly what I was looking for.
View 3 Replies View RelatedThere are often times when the best way to launch an application is from the terminal, but it is a graphical application and after it is launched the terminal is useless.
Examples of places where a terminal is convenient are when a process starts lots of child processes and is also unstable; you can be sure to kill all of its children simply by using Ctrl-C at the terminal. Also it allows me to read program output and to set up the terminal environment to be optimal for the application (for example "unset LIBGL_ALWAYS_INDIRECT")
With GNU screen, I can get around the hassle of having a terminal window open by using something like the following in a terminal window:
Code:
screen
my_command
Ctrl-A d
and then I can close the terminal and the program will keep running. Then I just type "screen -r <Tab>" (the tab will get me my screen session if there is only one such session) in any terminal window, even a tty, and I can get the screen session back and use Ctrl-c or something.
So my question is, is there a way to do this automatically so that a launcher or script will start a screen session, inside that screen session start a process, and then detach from that screen session without me having to manually open and close a terminal and type the commands?
I am downloading a big file on linux VPS, and I am connecting remotely via Putty to do it? Once I initiated the wget command to download the file, if I close the putty window, will wget continue to download the file in the background even though the session is technically closed?
