If I start a process with nohup:
nohup WHATEVER &
then how can I see it again? I mean how to attach my terminal to it again under Linux, e.g.: Ubuntu 11.04 - just like with the screen package.
I run
nohup bash -c "while [ true ]; do echo test; done"
from PuTTy SSH client but after this process is not runned in background instead nohup keeps to be foreground process in shell.
SW version: nohup (GNU coreutils) 8.5
I have a ssh command as shown:
Code:
ssh remoteusr@<ip> "perl ./monitor.pl count_pages" | /monty/graphs/mail.pl
This command connects to remote machine and fetches data which gets continously streamed at screen(shown at terminal). If I do Ctrl+Z and bg to put it into background. Works Fine. But when i close the putty, it gets closed surprisingly.
I tried with nohup <command> & But wonder how to provide password.
Does the nohup command make a process immune to the HUP signal by sending the process to the background or does it achieve this by some other means? If it it does send it to the background, then are all background processes immune to the HUP signal? If yes, then we can make processes go to the background for getting immunity against HUP by using the bg command as well can't we?
View 2 Replies View RelatedWhen I run a script with nohup, the output is forced to the out.log file by default; is there a way to force the output to the screen instead of the file? I need to be able to see when my script gives me a "process started" message, and I don't want to clog up the system with log files.
View 2 Replies View RelatedI have a question about NFS and CentOS 6.0. Here is the environment: Server running VMware's esxi 3.5 (Fully patched) 10.1.1.50 Server running CentOS 5.5 with NFS. 10.1.1.51 With the systems in the above config everything is working fine. Install a new hard drive in the CentOS server and install CentOS 6.0. Use the same IP 10.1.1.51. Configure NFS, the VM server can't attach to the NFS share.
Here is the config of the NFS server:
Firewall Disabled
SELinux Disabled
NFS installed and running.
NFS-Utils installed.
Contents of /etc/exports
[Code]...
I have confirmed I can telnet to the ports listed. Any clue why the setup with CentOS 6.0 doesn't work? Is this a NFS4 vs. NFS3 thing? Is there a way to force CentOS to use NFS3? I am pretty sure the CentOS 5.5 server is using NFS4.
How can I get more information about the error?

View 4 Replies View RelatedI want to use nohup and script command together but they don't work. Normally I use
Code:
script -c "./run arg1" run-log.txt
Then I want to send that command in background with nohup:
Code:
nohup "script -c "./run arg1" run-log.txt" &
but I get this error:
Code:
nohup: ignoring input and appending output to `nohup.out'
nohup: cannot run command `script -c "./run arg1" run-log.txt': No such file or directory
I ran a perl script in background with nohup and disown to make sure my script runs even after the parent process is terminated.
Method 1: nohup
> nohup perl run.pl &
[1] 2080
Method 2: disown
> perl run.pl &
[2] 2448
> disown
In either method, the script process doesn't seem to connect to init process, when I checked using pstree command. I thought, the disown or nohup command detaches the process from its parent and attaches it to grand grand parent init process. And it disables SIGHUP signal to my script process. But the pstree command didn't show me what I expected. It still shows my script process attached to my current terminal process. I just don't understand the concept behind these two commands (nohup and disown). Is there any way, I can see the list of processes that are run by nohup or disown command?
I had a make file which deals with hundreds of thousand jpeg images. I submitted this job by using: nohup make & Is there any possible way that brings this program back to foreground? I can only use ps to monitor the status, command jobs cannot find it.

Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.
as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.
How do you find the parent process of zombie processes?
When the child process is something where the parent is not entirely obvious...
Is there some way to list processes in tree format or something?

If I attach an NTFS drive to opensuse 11.3, will the OS see the drive and the files?
My goal:
I wanted to install OpenSuSE and add VMware Server 2.02 on top of it. I have a few hard drives that are NTFS. I need for my Windows virtual machines to see those hard drives. So in order for that to happen, the host OS would have to see the hard drives as well.
If I want attach some images to e-mail or facebook, I can see just a names of files, usually numbers only. It is dificult to choose the right one, if I can not see prewiews. How can I do it?

View 2 Replies View RelatedI have recently acquired a HP MSA 2040 san, which they say will work with Red Hat. But I'd much rather use Debian. It's attached to a Gen 9 DL360. I cannot get the OS to see the external drives. I hope it's just me mssing something.
I have told the DL360 to keep the external control in HBA mode, not RAID, not using the hosts RAID intelligence. I think I have set the MSA to offer a couple of disks as a virtual drive. I CAN see the drives in the BIOS boot menu for the DL360, though it doesn't show the virtual voilumes on the MSA, I cannot see the MSA virtual or physical drives once Debian is installed.
I have installed multipath-tools, and the SCSCi utilities.
But no luck seeing the drives.
