We all know how to kill multi process but if we want to send different signals to different process like to stop,-9,to hungup simultaneously at the same time then how we will do it,is there any particular command to do it.
View 1 RepliesI'm having a problem with setrlimit() under linux.
If i used setrlimit(RLIMIT_AS) to set a hard ceiling of virtual memory usage first, then request memory more than that, shouldn't i receive a signal like SIGSEGV?
First i tried the command ulimit in bash, which acted as if i called setrlimit(). i tried 3 programs that overflowed the memory limit i set. i though all the programs would be terminated by a SIGSEGV. but the pascal program received SIGKILL; the C++ program got SIGABRT› the C program, SIGSEGV.
I though there maybe something different between setrlimit() and ulimit, so i wrote a program in C++, fork() first, setrlimit() then execv() in the child, and wait(&status) in the parent. but i got the same result.
I was wondering why these could happen, and could anyone tell me how could i deal with them? i mean, how can i judge that the program exited abnormally because it exceed memory limit?
in the middle of script, i need to send the output of (send command on line 8) to a file
#!/usr/bin/expect
spawn telnet 172.20.64.133
expect "ENTER USERNAM <"
[cod]....
i treid the below on line 8 :
1- send "show command;
" > logfile.txt : gives an error extra character after the "
2- logsave logfile.txt 'send "show command;
" ': error invalid command
3- i simply tried to send the output of the whole script to file logsave /home/logfile ./script : seems that logsave work under root only
4- ./script > logfile : the problem with this is that the output of echo or (read "enter your id") command will not be displayed on the screen (actually nothing will be displayed, i have to open the log file to see the output). is there any way to save the log of the "send" ? or to save the log of the complete script without hiding the output on the screen?
I have a desktop hooked up to a router and plugged into my TV. I like to run Totem and have videos running full screen on my TV. I would like to control that Totem using my laptop (connected to the same router over wifi). How would I go about doing that? I connected to my desktop using SSH and tried to send signals to Totem, but nothing worked. I tried using VNC, and that was ineffective as well.

View 5 Replies View RelatedI'm currently writing a C++ application to manage some screen functions in Debian(server).
However this issue have bothered me for 2 days now...
What I want to do is to send a command to an attached screen which is running.
Used the following command: Code: screen -S screenwindow So I send a command with the -X parameter, which works just fine... Code: screen -S screenwindow -X stuff yes The command I want to send is "yes" and it does appear in my screen window when I attach it.
But the problem is that I need it to submit it... well I need to press "enter" and I've been looking everywhere on how to do that.
Because right now it hangs on a line like this: Code: Something here, do you want bla bla: yes Obviously I could just press enter myself, but the problem is that it's running as a deamon and but it is supposed to do this all by itself .
So are there any way I can submit it?
Is there a way to configure the at command to send to someone other than root?

I was actually looking for a way to clear up the second terminal.

View 2 Replies View RelatedI've got a Debian Squeeze computer on which the graphics have packed up, but the terminal in single user mode work perfectly fine.
There are a few files on this Debian computer that I want to transfer off, to a networked computer, but I have no idea how to do this.
The destination computer is a freshly re-setup Mandriva install, without (as yet) samba. I don't think it's necessary though. The Mandriva install works fine, has graphics, etc, but can't see the Debian Squeeze computer on the network, possibly because it's in single user mode, thus prompting the problem of how to transfer the files, using only a command line.

I'm a little stumped on this one, I've tried using mutt but it doesn't encrypt mail unless it's used interactively.

I've just setup a new Ubuntu 10.04 LTS server on linode for myself. Followed an excellent instruction at: here to finish the installation of some basic stuff including postfix.
I am trying to figure out a way to send an email to my gmail address with an attachment, but cannot find how. Already confirmed that email can reach my gmail account.
In the end I have to use mutt to send the email with attachments, probably SendEmails will also do well, but I am wondering how to do the same thing in postfix from command-line?
how to include my command results in a script? Basically what the script does is it checks the status of a service within the linux server, then sends an email when done. I want to include the results of my status check to my mail when sent.
i.e.

Linux downloaded new updates and worked perfectly. Next time I started mint, just before the login screen appears display says No Signal and goes in sleep mode. I think that mint downloaded somekind of display driver update wich is not compatible with my driver card. I can't see desktop, I just hear the login sound and that's all. What should I do? I'm new with linux.
View 6 Replies View RelatedI'm trying to create a signal handler thread to handle SIGALRM signals. The main thread calls the following function before creating any other threads
Code:

clock_interval is 50.
Is the timer not firing? Did I not set my interval correctly? Did I not proper block the signals ensuring the that the default handler would not take care of them?
In my Windows environment, I use email client such as Microsoft Outlook to connect to our email server to send email with the following configuration:
Incoming server (POP3): 995 - (requires with SSL)
Outgoing server (SMTP): 465 - (use encrypted connection SSL)
[code]....
And the mail server requires user ID login and password.how do I setup a text command based email client in my Linux (Centos 5.1) to send out email through the existing email server above, which is in another machine? The email client has to be text command based because I need to use command line to send notification email from anothar application installed in my Linux (Centos 5.1) Since the email client will only be used to send email notification, I don't require setting up of an email server in my linux.
