General :: Crontab Show Live Timing/queue Of Upcoming Jobs?

Nov 18, 2010

is there a command or utility out there anywhere which can output a countdown of upcoming jobs from crontab? So you can display the queue of tasks in the order that they'll next run.

Anything like this out there?

EDIT: I realise there's crontab -l but that just echoes out the contents of the crontab file. I'd like somehow to get a countdown.

Ubuntu :: Print Jobs Stuck In Queue?

Mar 28, 2010

I have 2 printers plugged into a Windows XP PC (an Epson Stylus Photo RX580, and an HP Laserjet 1020) with full sharing on and everything, and is shared with other Windows PCs via the network I have set up. It has worked perfect. But today I added a PC running Ubuntu 9.10 and and can't figure out for the life of me what I am doing wrong. I installed both of the printers via the GUI in Administration, and both of them are detected and Ubuntu says they're working. But when I put something in the queue to print it stays there with the status "pending".

Debian Configuration :: Print Jobs Disappear From Queue?

Jun 16, 2010

I have no idea what's going on. I've had this machine running for over a year, and it's been great. A month or so ago, I realized that jobs weren't going to the printer. When i VNC'd in, I noticed that print jobs would show up in the queue as "Processing" briefly, then disappear.

Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub


I've even reinstalled the OS (not just for this reason) to no avail. Printer is dete cted without issue, I just can't use it.

OpenSUSE Hardware :: 11.3 - Print Jobs Just Sits In Queue

Jul 26, 2010

I'm running openSUSe 11.3 on a laptop and the printer is connected to my desktop which is running Windows XP. I have the printer and several folders and drives shared. I can see the folders and drivers on my laptop but I cannot get the printer to actually print. It is an HP printer but I am not using HPLIP. I can send a print job to the queue and the printer resets itself like it's going to print but nothing else happens and the print job just sits in the queue until I hit cancel and restart then printer.

Applications :: Firefox 3+ Doesn't Queue Lpr Print Jobs Until After Quit On RHEL5/10.04?

Jun 8, 2010

We have a lpr server for printing (not CUPS for compatibility with complicated domain/systems). We configured our linux systems -- RHEL4, RHEL5, and Ubuntu 10.04 -- so that lpr is one of the gtk print possiblities by adding 'gtk-print-backends = "lpr,pdf,file"' to gtkrc. This works great for several gtk-enabled applications like Acrobat Reader (acroread).

However, Firefox 3+ (tested 3.6.3 & 3.0.19) doesn't actually queue any lpr jobs until after quitting the application.

Ubuntu :: Start Live Timing Caused Firefox To Become Unresponsive?

May 9, 2010

Running a clean install of Lucid 64, I have a problem with the Firefox Java plugin with the "Live Timing" feature of the www, site. Live Timing is an applet they provide that displays sector and lap time information for races, practice and qualifying sessions. It was working fine under Karmic 32 but no luck so far with Lucid 64.

Initially trying to start Live Timing caused Firefox to become unresponsive, I saw that the Java plugin being used was the IcedTea one, which I have heard can be a bit flakey. (Not sure what I was using under Karmic BTW).

I notice that the Sun proprietary Java stuff is installed - I presume when I installed ubuntu-restricted-extras. So I disabled the IcedTea plugin in Firefox and tried to use the Sun Java Moz plugin by creating a symlink to



Firefox then lists the Sun proprietary plugin under addons - plugins but it doesn't actually seem to do anything, as I just get an empty Window with the Live Timing Applet.

is it possible to get the length or even the items of both queues, the run queue and the swap queue? I've googled a lot but had no luck. Maybe I havn't used the correct search words...

Is there any header and/or code example to use structures or any API to get these information from the kernel or the scheduler?

General :: Using SSH To Access It From My Windows - Keeps Timing Out

Mar 11, 2010

I just installed my first ever install of Linux (used Fedora) and am using SSH to access it from my Windows machine. It keeps timing out. Is there something I need to set to make it available all the time?

I was able to get the SSH on and to autostart just fine but when I boot up it only works half of the time. I have to move the mouse and keyboard on the Linux machine before it will respond.

Also if I am working on my Windows machine and don't move the mouse or keyboard every now and then it doesn't work.

Ubuntu :: Can't Show Or Block Stuff In MoBlock On Live USB

Jan 12, 2011

After some difficulty I got MoBlock and Mobloquer installed on my Ubuntu 10.10 live USB. Lists all updated perfectly, and I made sure that HTTP and FTP traffic are not allowed. All's going well, still it shows nothing under the "Logs" tab, and under the "Manage" tab, "Number of blocked connections: " is still 0. MoBlock is "up and running". Now I did some browsing as a test, cuz I'm pretty used to Peer Guardian on Windows, and I know that by now it should have blocked quite a lot of stuff. Should I have "No time stamping" checked, cuz in the "Blockcontrol log", whilst struggling to get it working, it said that "notimestamp" was a depreciated feature.. or some thing like that anyway. It still shows nothing under the "Logs" tab, and it shows "no blocked connections under the "Manage" tab still.

General :: Intermittent Internet With Ubuntu Natty - Connections To Particular Websites Will Start Timing Out

Aug 28, 2011

I'm having a bit of Internet trouble with a fresh install of Ubuntu Natty and I haven't been able to track down the problem. I have my desktop running over a wireless network, which connects without fail. Somewhat frequently, however, connections to particular websites will start timing out (google, facebook, stackoverflow, us ubuntu archive, etc.). I'm also having a strange issue where my home page [URL] is redirecting to [URL].

Initially I thought it might be an issue with Comcast DNS, so I updated the router to use OpenDns servers. When that didn't work I started to try accessing some of the problematic sites through my laptop (which is using the same router) and they all connect without problem. The issue seems to be with my Ubuntu install, but I'm not sure where to look.

EDIT After doing some further digging, this is starting to look like a DNS issue. My home page appears the resolve to an incorrect ip address when the redirect issue occurs. Still not sure how to track down the problem, however.

Ubuntu Servers :: After Using Crontab With /etc/crontab / Giving Error "can't Find Command Root"?

Aug 26, 2010

I have a question about using crontab with /etc/crontab...

I had a cron job that I needed to run as root. At the time I thought that sticking it in /etc/crontab would be a good idea. However, I used the crontab command to edit /etc/crontab, which I guess is not standard procedure? Specifically, I configured /etc/crontab as my local user's crontab (i.e. sudo crontab /etc/crontab) then added my cron job as I would a local user crontab (i.e. sudo crontab -e).

Originally, my cron job looked like this:

30 * * * * root /my/batch/script &> /dev/null

After adding the new cron job I started seeing errors. Something to the effect of "can't find command root" or something similar. So I removed the 'root' user definition from the cron job and the job started running fine. However, because this is /etc/crontab, there are other system related cron jobs that have been defined to run under the root account (e.g. "17 * * * * root cd / && run-parts --report /etc/cron.hourly" runs as root, etc.). So these pre-existing system cron jobs, which up until now have been running smoothly, are now generating "can't find command root" errors. But I think that the system cron jobs _are_ successfully being run someplace because logrotate seems to be working.

So what I _think_ is happening is that /etc/crontab is being run twice: once as the system crontab, and once as my sudoed local user's crontab. When I run crontab -l I see nothing, but when I run sudo crontab -l I can see the contents of /etc/crontab. I am reluctant to delete my sudoed local user's crontab, because then in the process I would be deleting the system crontab, and I do not know how I should restore the system crontab's contents. (I am still not sure as to the most appropriate way to edit the system crontab).

How can I get out of this mess? I want /etc/crontab to go back to the way it was before--running _once_ as the system crontab. As for my new cron job, I'm willing to reconfigure it anywhere so long as I am still able to run it as root. Any ideas? (I am using Ubuntu 8.04 Server LTE)
