I need to printout auth.log each line by log event, I think it should be running using the following command:
~# tail -f /var/log/auth.log | lpr
but it's not, why?
the lpr package already is installed in myserver, there is no problem to print directly.
~# cat /var/log/auth.log | lpr

For doing this, I clicked the hardcopy button and select the device/file to save the file... but nothing happens... and 1 more query is that i have searched the whole Internet to find why the packets are not transferring in Tora...But I could not find it.
View 6 Replies View RelatedI was recently looking into using tail -f to monitor some text files like so: tail -f /var/sometext However, when I did some testing, it doesn't seem to work. What I did was I created a new file and ran: tail -f /home/name/text Then, I opened the log in vim and did some editing, saved it, and it seems that tail is not "seeing" the change.
The weird thing is, running echo "hello" >> /home/name/text seems to work fine (tail sees the change). I read somewhere this has something to do with file descriptors and new inodes being created when saving a file.

View 5 Replies View RelatedI was using happily Brother DCP7030 printer with CUPS on Ubuntu 10.04 for several months with no issues at all however recently I've started having problems with printing anything which is even a bit complex ( like 2 pages pdf, jpg file, etc..., simple gedit files are fine) - after printing properly up to one page the printer is producing one page like the one from attachment (with bunch of vertical lines starting in random places) and then "printing" unlimited number of blank pages until I will force it to stop. Any ideas ?
Ps. The printer itself seems to be fine - printing perfectly when connected to windows or other ubuntu machine configured exactly the same way like the one affected. Removing CUPS and installing it from scratch didn't help.
I have just installed OpenSUSE 11.4. Everything works perfectly on my HP Probook 4520s. Except my canon printer LBP3100. I downloaded the files from Canon for the CAPT and CUPS drivers ver 1.90. Installed and did exactly as they said in their manual. When I plug in and add printer with YaST, Open SUSE sees the printer and installs it. However when I try to print, nothing comes out!!

I have installed Ubuntu 11.04 over the weekend and wanted to tail the logs whilst doing so stuff. When I browsed to the folder after getting an error trying to tail, I noticed that the messages file does not exist.
Usually use tail -f /var/log/messages
tail -f <filename> is not working as planned on my Ubuntu 9.10, it doesn't show the appended data.tail -F works, but it does not append the new line, it reopens the file with the message: "tail: <filename> has been replaced; following end of new file"

I'm running ubuntu 9.10 with the latest networkmanager (from ppa)I thought this could be wrong credentials setting, so i've tried a huge amount of setups (user: phonenumber, password: phonenumber, avp:telenor, seems to be the general consensus for how it should be)Is there something I'm missing or is there any way I could tail the output as NetworkManager tries to connect (hopefully seeing something like "wrong password" etc.)
View 6 Replies View RelatedI was using Opensuse on Virtualbox earlier today. I issued the tail -f /var/log/messages command on Opensuse 11.3 to see the messages. Then I logged in from my Mac into Opensuse 11.3. I noticed that Opensuse was displaying realtime messages of the things happening. For eg, I entered a wrong su password and it displayed that too. But no such things were happening on my Fedora 13 installation. So is there any way if I could get some realtime messages on Fedora 13 too like the one on Opensuse..?

I am running a script with nohup and this generates a lot of logs.
In order to view the log I use tail -f nohup.out
The problem is that the info supplied by this command is not always the latest//sometimes I need to use the command again order to view the latest info added to the nohup.out file.
I have had update problems for a very long time in my desktop e-machine. Maybe since 5.3. Usually something about Gwenview and other things. And, while --skip-broken got other packages updated, sorry, an incomplete update just isn't acceptable. Because of this I stopped using Centos for a long time. Yesterday, I got ambition and gave it another try. I had a lot of yum upgrade failures when upgrading 5.4 to 5.5, using --skip-broken.
I decided to fix things or delete Centos completely. But, I like the idea of free R****t. I realize this may have been posted, but I had no luck finding it via Google, So I started Googling. I soon found the --disablerepo option, and playing with repos, got most of the failures to upgrade. But, still hung up on a lot of stuff, like 11 packages or more.
Next, I learned about yum-prioroties and setting repo prorities. Yum-priorities was already installed, but I did go in and set the priorities. Since Google has a lot of information on this, I will not repeat here. You go into the repo config files and add a priority number to each repo listing. Here is a script to display repo priorities that I found online, sorry, I lost the author:

How to print a sequence of line say line number 10 to 20 of a 50 line file ?
View 6 Replies View RelatedFollowing script name is 123.sh and I need to put this in the background if I do 123.sh -bg this will not bring me back to the prompt but echoes what ever I put (using echo hello >> /tmp/123) in to the /temp/123 file. the only way that I have found doing this is to do "nohup 123.sh &" to put this in to the background. Is this okay or is there any better way of doing this?
#!/bin/bash
# file name is 123.sh
tail -f /temp/123 | while read line

By invoking x11vnc with the -gui tray option the TCL/TK GUI attempts to embed itself onto the system tray, but I encounter the error message "tail: cannot watch /tmp/x11vnc.tray.*", after the first settings dialog approved [clicked OK].

View 9 Replies View Relatedon certain folders on a samba-server I would like to allow everyone everything.(Note: This refers to the filesystem-permissions. External security is cared for by samba. No problem here)That means: every local user and every remote user should be able to fully create, delete and modify every file in certain folders and all subfolder of these folders. This should include file contents and timestamps and permissions. And it should include modifying files owned by someone else, again meaning create/delete/modify/timestamp etc.
