After installing ufw which is supposed to be a firewall system for the network-challenged, I am getting tons of these messages showing up in my dmesg;

I am trying to dump /var/log/messages using cat command, but it is failing.
Quote:
Command:

Op:
cat: /var/log/messages: Invalid argument
messages file is present in /var/log. When I tried to open that using 'vi' it is saying 'messages' is not a file. First column of command "ls -l /var/log/messages" is '?rwsrwsrwt'.
I am seeing cores dumped in a particular directory continuously. I am sure there must a script that's continuously starting a process which is core-dumping and dying. But, how can I find which process is it?

I bought a 120 GB hard drive, and want to dump windows totally. If I download clonezilla and burn it to a cd, can I instruct it to only clone the Xubuntu system? I think I would run clonezilla from a cd, download everything to my USB drive, then remove the small hard drive. Then, install the bigger drive and restore everything to the newer and larger drive. Will this work??

I have a syslog-ng running and kernel build of 2.6.34.8 I use a syslog API in my program with facility LOG_LOCAL5 and and levels debug err and crit and info. when I ran on the older syslog facility I had everything logged fine as I intended. now I have written these rules into the syslog-ng.conf:
options {
flush_lines (0);

the last two rules show my program gnssapp. the result is all debug levels or crit or err levels I don't see any of them !
I am now for four weeks on Wheezy KDE after turning away from PCLinuxOS.But now that Jessie KDE is out, I installed it on a free 20 GB partition to have a look.What I really like is the following:
At start up on Wheezy GRUB MENU - INIT messages - KDE welcome screen -> desktop..I am missing those INIT messages. Gives me a good feeling for system status.I understand, we now have systemd, but is there a possibility to have those reassuring messages at startup and maybe also at shut down?

What this means and how to fix it?
During the boot-sequence of jessie there is more text flying by on the screen (including some errors or warnings) than I can read thorugh fast enough. I don't think this is very serious stuff, and if it were I could always look at dmesg and or syslog i /var/log but I would find it really convenient to log these messages in a file instead of sifting through or grep-ing dmesg.
When duckduckgoing this matter I found [URL] ....
I installed tried bootlogd but when configuring it to "yes" and rebooting nothing comes up in /var/log/boot.
Then I saw this line in above link
If you use systemd as your init system, you may need to use systemctl to debug boot problems.

An issue that has been hassling me for years since I started using Linux (Debian!) is related to the boot messages that quickly scroll on the video during the boot process. The main hassle is related to the fact that I cannot get a log of those messages. The second hassle is due to the fact that with my brand new netbook (Toshiba NB200) I cannot even stop the scroll and go back along the message stream with SHIFT+PageUpDown to understand what's going on. Of course I know that I can get a log of the boot process with 'dmesg' but I get the feeling that the very first lines show some problem I cannot grab at all.
View 2 Replies View RelatedI'm running GNU/linux systems on all my PCs: Debian unstable, Ubuntu 9.10, and use Clonezilla (alternative based on Ubuntu Karmic), SystemRescueCD (beta and stable) to diagnose problems if needed.
My issue is that I've got a few hard drives that I can no longer mount either under linux or Windows, but Windows at least sees all the drives whereas linux sometimes tells me absolutely nothing:
1) one drive (Seagate 250GiB AS drive) has an ext3 file system, and /var/log/messages shows me lots of lines of information for the USB connection when I attach it, including the size of the drive, but can not mount anymore. Windows too sees the drive. I haven't tried to recover data from it.
2) two drives (not mine, both 500GiB drives) have NTFS file systems. With these, when I attach them, there is not even one line of information in /var/log/messages, or in the kernel or authentication logs. However, on the same computer booted up with Windows XP SP2 the device is seen by windows, including the size. Windows cannot mount the drive, but recovery software can after about 2 weeks' running, recover virtually all the data (I let it run using each of the various options for the guessed drive geometry/file system settings).
So my question is: why would linux not even give me a single line in /var/log/messages, not even to say that something has been attached to a USB port? I'd like to believe that linux does see something but that the USB/SCSI emulation is somewhat faulty and could be improved.
I'm not sure what kernel modules I should be looking at for the physical connection control.

View 2 Replies View RelatedI'm trying to stop all boot time messages from appearing -- basically I'd like to have a simple blank screen from grub to xdm.
I tried everything -- used the "quiet" option in grub's config, added dmesg -n 1 to rc.local, changed console=ttySx, set kernel.printk in sysctl.conf to 4 1 1 7, and even eradicated rsyslogd altogether... to no avail. I still see all sorts of messages on my screen.
Howto hide boot text messages on the screen during Lenny startup? I've tried to change in /boot/grub/menu.lst:
Code:
## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash
The system crontab (/etc/crontab) uses the same format, except that the username for the command is specified after the time and date fields and before the command.
[code]...
Every hour, I get an e-mail complaining about the first line of the crontab:
[code]...
I get the same complaint from the other entries: It looks to me as if cron, or anacron, is trying to execute the user (root) as a command. Predictably, the shell doesn't like it, so barfs and triggers an e-mail about it. Why is this not doing what the man page says it should do? The 2nd problem I believe is related to exim, not cron. The e-mails I'm getting above are being bounced from my ISP because they are directed to root@myisp.com, rather than my regular e-mail address. When the message bounces, it bounces to my regular e-mail address. In /etc/aliases, I have root: [URL]... and in etc/email-addresses I have root: [URL]... Adding the entry to /etc/email-addresses allowed the bounce to find me because the sender's address is [URL]... but how can I get cron to send these messages to me in the first place, instead of root?

I've got a Shorewall (Shoreline?) firewall up and running, but it's logging to /var/log/messages. I'd much rather have it logging to another location e.g. /var/log/firewall but can't find (a clear enough) explanation on how to do this. Apparently, it varies greatly depending on the distro, the kernel, and the version of Shorewall that is running. You'd think it would be something as simple as setting a path in a config file, but apparently not. I'm running a stock Lenny kernel on the firewall machine. It comes with version 4.0.15 of Shorewall.
