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"

Now - I have no problem logging in a Root. Is there a way I can try to stop the login process before it kicks me out, or is there a way to look at some files to tell me what's going on?
View 3 Replies View RelatedI 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
I am trying to use tail -f and play a sound everytime a new line appears. I tried this: for i in tail -f myFile; do aplay alert.wav; done; Which kinda worked, the output is:
Playing WAVE 'alert.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Mono
Playing WAVE 'alert.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Mono
Playing WAVE 'alert.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Mono
But after 3 times it stops, and I would like to print the tail -f result and not the aplay result. How could I achieve that?
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..?
View 4 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.
I need to tail -f a log file that is rotated.
This is the exact same issue as the one here, but on OS X:
Why does less tail mode stop working?
So how can I constantly track a file whose inode might change under OS X?
am facing a problem with tailing a log file. Logs of application located in one folder:applog_20100101_0200.log <--log until 2 am january 1applog_20100101_0456.log <--log until 4:56 amapplog.log <-- current logApplication can change log when ever it wants to. I need to monitor this log, what i do:tail -f applog.logBut when app changes log my tail just stops. How can i tail applog.log all the time with out stops?

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:

On our app server the logs from the Sybase Mobilink service get logged to /var/log because of that I did a chmod a+rx /var/log and all is well until.... the next day QA logs in goes to check the logs and gets:

I'm trying to write a script that will either tail or watch /var/log/messages for the words

I would then like the script execute:

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]. I believe that a package is still missing to be installed and this is not really a software bug. I use the XFCE version shipped along F15, and the GUI can be started but not as a docked-applet.

So everytime I resume Ubuntu from hibernation, it remains black for a time then 2 messages on the screen appear for about 10 seconds before I can log-in:

1) THE SETUP: I have a home set-up with 3 Ubuntu computers, including an HTPC which is always on, plugged into a Verizon FIOS routerI also have a web based cam (TrendNet TV IP422W).The cam has an ethernet jack so it plugs in directly to the router.It has a simple firmware that allows users to log in via HTTP.It is also managed via HTTP.
2)THE PROBLEM: the cam does not keep logs.So I never know who is logged in at any one point. It's not a big deal, but it is annoying.I want to fix that.The router does not keep logs either.I was told I can get a linux based router to replace (or plug in) to the default FIOS router, but I am looking for something simpler and cheaper.
3)THE FAILED SOLUTION: my idea was to set up the Ubuntu HTPC to always forward a given port to the webcam via the LAN. I tried to follow the instruction from URL...as best I could, see below. 6666 is the port that the cam is listening to (the router is set to forward that port to the cam's LAN IP 192.168.1.30). 5555 is the port that I am trying to forward through the HTPC (ubuntu.local or 192.168.1.130 below, and the router is set to forward any 5555 TCP packets to the HTPC at 192.168.1.130).The iptables commands below where run on the HTPC.
My laptop Dell Inspiron 1420 running Ubuntu 10.10 has started logging itself out every 30-60 minutes or so. I am trying to figure out what is the problem. I am wondering if it is
1) a hardware problem. I have recently replaced the cooling fan which required disassembling the whole thing into small pieces. The computer has worked without a problem for one day after the repair.
or
2) a problem with a recent update. The computer started logging itself out after a recent update. This coincidence is suspicious, but I hasn't noticed anyone reporting a similar problem with Ubuntu 10.10.
Is there a way I can see what is happening through the system log? What would be the keyword I should look for in the log files?
Can I track the last updates I have applied and roll them back?
The only solution I see now is to reassemble the laptop to see if it helps.
Ubuntu one does not synchronize files since I upgraded from 9.10 to 10.04. The preferences panel keeps showing "Synchronization in progress...", but files are not downloaded from the repository. It does not show any error message.
Where do I find the programm logs, where I can investigate my problem?
I cannot find one single UFW event anywhere. I have researched this and see that others have trouble finding these logs too. I have looked in every /var/log there is and I can't find one event. I have UFW enabled, default deny and logging set to medium from a previous logging low(in hopes this would create more events to be seen). In terminal, UFW is shown as active. I have been using Ubuntu for more than a year now and I recall seeing UFW events with every session in some /var/logs in Ubuntu 9.04 - I'm running 9.10 now. I have also tried looking throughout the system files and have found nothing. Is UFW not working properly or could I just not be experiencing any firewall events(not likely)?

View 1 Replies View RelatedI don't know if this a bug or some setting that I have changed inadvertently, but when I start up my computer Ubuntu now logs me on automatically to the sole user account I have created but without asking me my password.I rarely fiddle about with settings and am not aware of touching anything to do with user accounts etc. Obviously I don't want this behaviour otherwise I wouldn't have put a password on the account. Everytime I log on I want to choose what language I want to run my system from the log on screen.
In administration > users and groups > it says my user account password is asked at login.Is there an option somewhere else to turn this behaviour on or off?how I could have accidentally turned this behaviour on?
Is there anyway to view the Boot Log of the messages displayed during the booting of Ubuntu? I found log file viewer under Administration but there were so many logs I did not know if any of them were the Boot up logs. I have my Ubuntu configured to display the messages as it boots before it switches to GUI mode and I see an error message about something failing to initialise but it goes by too fast to read the entire error message. I have Ubuntu 9.04 64-bit
