I have a server here and want to set up transfer jobs to run overnight.
I log in via SSH to it from my laptop and would like to start the job, disconnect yet still have it run.
Is this possible, if so, how?
I run a headless Ubuntu file server which I access remotely via ssh or using VNC. After reboot, short of moving monitors around, is there anyway to start the GUI and continue using VNC as I normally would? I still rely on the GUI to get done what I need for the most part.

View 3 Replies View RelatedI have a file server that is an NIS client. User home directories are auto-mounted from another server. Users are not able to run cron jobs. The /var/log/cron logs says:
Jan 6 14:33:01 inclination crond[3217]: (username) ORPHAN (no passwd entry)
I tried adding an entry in /etc/passwd, /etc/group, and /etc/shadow but the test script I have still doesn't seem to run although cron thinks it did. The log entry for these attempts looks like:
Jan 6 15:30:01 inclination crond[4312]: (username) CMD (/home/username/test-script)
Now root does seem to be able to run cron jobs with no problem. My test script works fine from cron when runs as root. I suspect there's an issue with how I have NIS configured but I can't find any info. The test script runs fine from the command line when logged in as myself.
We're running
$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.4 (Tikanga)
$ uname -r
2.6.18-164.11.1.el5
It hosts an Apache/2.2.3 web server. We also run apache-tomcat-5.5.23. Most of our programs are mod_perl. Sometimes our users input over-sized data sets, or queries that generate too much output. (I realize that we should try to prevent them from doing that, but right now I'm looking for a more general solution.)
When a large job runs it can 'freeze' our system. The system becomes unresponsive to everything, including command line commands. Sometimes it unfreezes after a while. Once, in this situation I was able to create a high-priority shell. ps reported:
[Code]...
Observing the machine, I see at least one very busy disk. I suspect that some high priority system process (perhaps kswapd) is using all the cpus, preventing anything else from running. Unfortunately, I cannot find much info on kswapd, or debuggging this problem.

I have a 11.3 machine as a print server sharing out a printer Then I have two clients using that printer. One 11.3 and one 11.4 6 of 6. When I print from LibreOffice on either machines every other print job disappears. I'm a bit puzzled ! It's not random it's exactly every other that doesn't show up at the server. It's not in the server job log.

View 4 Replies View RelatedI have this basic program that is supposed to scan a string for a delimiter and output which segment of the string the user wants, like awk '{print $2}'. The problem is, I always get a segmentation fault when I run the code and I can't figure out what triggered it.
Here is my code:
Code:
int main(void) {
char *string = "my name is joe";
char dlimit = ' ', *good;
int index = 2, round = 0;
int i, place = 0, t;
[code]....
It keeps track of how many times the delimiter was found with round, and the position of the last found delimiter with place. index is to specify which segment of the string the user wants. One more thing, is it necessary to manually allocate memory with malloc() or calloc() when you can just initialize a variable and it be fine? Like:
Code:
int z = malloc(sizeof(int));
when you can:
int z;
I'd like to know if it's possible to automatically mount, and fire up rsync to sync a USB drive with a directory? Specifically, I'd like to copy as much data as the drive can hold and only delete the oldest files if space is needed. I would assume I'd do something like this with a script, but my problem, is where to start.
View 2 Replies View RelatedI have a keyboard&monitor damaged laptop which I've converted into a media server/HTPC with a large external monitor. I've installed Ubuntu 9.10, and attached an external 1TB HDD with my video collection. As a media player it works perfectly fine. I can connect to it through my home network, both with VNC and with SSH. I can use VNC on my current laptop to access the player's desktop and play video files. However, this is awkward as the screen resolution of the playback monitor is 1920x1080 - much bigger than the laptop's screen - which means I either end up scrolling the viewpoint around, or scaling the virtual screen down to make reading text very difficult.
What I'd like to be able to do is to trigger Gnome applications - specifically the Totem video player - via a SSH session, on the current Gnome desktop. The idea is that I'd like to be able to browse the directories which house my video collection in SSH, launch the player in the session, and have it appear on the monitor. Ultimately, I'd like to be able to invoke this from a PHP script - thus allowing me to create a (simple) web application on a LAMP installation which would allow me to browse & play my video collection. Currently, when I try and invoke totem, it seems to want to connect the invocation of the software to the SSH session, which - of course - it can't do. Where I might start in trying to set this up?
I use network-manager-pptp to connect to my VPN server. However, occasionally my VPN drops out (although my Internet stays up). I was just wondering how I could make the VPN drop-out trigger a bash script, for example playing a sound to alert me that the VPN has dropped?
View 1 Replies View RelatedI have what I hope someone finds to be a simple problem. I am running a data acquisition computer for a research project, where multiple people use the same non-privileged user account to take data and save it to /incoming. Once the file has been closed, I would like to somehow copy the data into a more permanent location owned by root. Obviously giving the shared user account sudo permission would be a huge security hole.
I know that this should be possible using some sort of client/server connection, but writing my own server just for this little task seems a bit cumbersome, and is something I have no experience with. Nor have I ever written a daemon/init script before.
Does anyone have any ideas on a simple procedure I could use? Very few things are fixed in stone, but the copy operation is necessary - the final location is a RAID5 array, and the write speeds are too slow to keep up with the data stream.
If a client/server type of thing really is the best way to go, anyone have any links to good tutorials to make a simple server and daemonize it?

I wanted to make a simple script that would trigger on certain environment events. For instance, I want the script to trigger whenever a new file gets copied or placed on the Desktop, and cut that file and place it somewhere else. Sort of cleaning the Desktop process. Here's the thing: I want to trigger on it's own, not requiring me to open shell and invoke it from there

when I update the ubuntu, I set it shutdown after 60 minutes uisng "sudo shutdown 60",because I think the update will complete in 40 minute. However today when I start the computer, it can not startup the ubuntu.

Is there a way trigger a shell script after my DHCP server successfully gives out, either a specific IP address or to a specific MAC address.I have two Xbox360's in my house that both receive IP address via DHCP reservations from the Ubuntu server.I have come to accept that without having two public IP addresses getting both to have an open NAT will be very difficult. I have decided that I am OK with only one being able to have an Open NAT at a time, but I want to change the firewall rules according to which Xbox 360 turned on first. This way I can move between level in my house and play online without having to modify rules manually.
View 3 Replies View RelatedI'm having a bit of a nightmare with my ubuntu hardy server (using hardware raid 1+0). Following a power cut I get the message "udevadm trigger is not permitted while udev is unconfigured" on boot. Before the power cut the server had been up for ~450 days.
I managed to get access to /boot (which was empty) by using the repair option on the alternate cd and mounting /dev/myserver/root. I've installed the packages linux-headers-server, linux-image-server and linux-server. The various 2.6.24-29 files were installed and update-initramfs was automatically run (I noticed others have used update-initramfs to solve this error when upgrading from 8.04 to 10.04 in some posts I've read). No luck with this though - just the same error booting. I've also tried reinstalling udev, but again with no success.
I rebooted and pressed the Esc key to get the boot menu up. Only options were for kernel 2.6.24-26 (rather than the 2.6.24-29 just installed). I ran the recovery option anyway and got "/dev/mapper/myserver-root does not exist".
Is there any way to automatically trigger a cron job each time I log in on my linux account.
