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.
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
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.
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 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.

Unfortunately, one of our employees cannot remember her password to her email account and as such I need to reset it on our linux server.What I want to check is that this email account is actually a linux user account and I simply will reset the password for it using the passwd command from the root login. Is that correct?

View 4 Replies View RelatedOn my linux machine, I've enforced a password expiry policy every 45 days. So, today when I tried to ssh to the host, I get the typical "WARNING: Your password has expired". Fine, no big deal. But when I enter my new password and confirm, instead of giving me a login prompt, it tells me passwd all auth tokens updated successfully, then next line, "Connection to <host> closed". I can re-ssh back into that host and all is well from here, but it's a nuisance having to go through the extra step. Is this something in the /etc/ssh/sshd_config somewhere or perhaps a PAM config issue?

In the VeloxBoot.sh, if I don't press any key, my application starts after a timeout. If the user presses a key I want to have a login prompt. Unfortunately, if I start /bin/login, I have a prompt with login, but once I enter my login, it does not ask for a password and it says wrong password
I'm really new to Linux so this will probably sound like a pretty naive question to most users, but how do you change the root password?To install Java, I have to type # su into Terminal,which then asks for the password.What's weird is that when I start typing a password, no characters show up. I don't know if this is supposed to happen or not.I've found a bunch of different sites on the Internet that explain how to change the root password, but none of them seem to work for my specific work station.
I've got Ubuntu 9.10 64 bit. In the GRUB boot menu, I can choose to boot normal or in recovery mode (I'm led to believe older versions don't have this option).I've tried typing # sudo passwrd into Terminal, but I already have a root password set up apparently, so I can't change it there.
I thought these were the same password?In-fact, they WERE the same password on the set-up I currently have.But now, weirdly, I can log in fine but I the exact same password is not using in order to perform admin tasks.I've tried a recovery mode, console, and then "password (username)" in order to reset the password.This does reset the password I need to use to log in, but the password still does not work for performing admin tasks
