General :: Review The Boot-time Info That's Going To The Console?

Feb 18, 2011

I'd really like to be able to examine all the information that flys off the top of my terminal when my system boots (off of fd0, the only way I've done it, so far): review of "similar threads" yields nothing; seemingly not a man pages item; have not found any how-to's that cover this; the daemons for logging are third-to-the-last before logon prompt (and still displayed, the ONLY reason I know THAT); seems like it should be a compile-time sw-switch settng (sub-optimal since I'm still not comfortable with compiling kernels); but I was hoping it's already being captured in some log file somewhere that I'm as yet unaware exists. I do realize that if I had a printing console, this would be unnecessary.

General :: Disable Console Messages At Boot Time?

Sep 5, 2011

I am using Arch Linux and want to disable console messages which are displayed when the kernel boots. I have tried the quiet and loglevel=2 options in /boot/grub/menu.1st as given below:

kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/c6dbfcdc-fcd8-498e-9182-f3bddc4f05ff ro loglevel=2

However I am still seeing console messages at boot. I used grub-install after the changes.

Any ideas where I am going wrong?

Ubuntu :: Run Perl Script In Console At Boot Time

Aug 2, 2011

I have the following command in my rc.local file.
xterm -e perl /home/user/
If I run rc.local from nautilus it works as expected. However when I boot nothing happens. I would like a console to popup and show the activity of the perl script.

Slackware :: How To Review Boot Messages

Mar 16, 2010

EDIT: not fully solved; there is (at time of writing) still an issue about bootlogd buffering until the logfile is accessible but that's probably as far as we are going to get for now, until someone peeks into the bootlogd source code.

Is it possible to review boot messages after boot? Kernel messages are available via dmesg (and many are logged early in the rc.M script by the /bin/dmesg -s 65536 > /var/log/dmesg) but many console boot messages are not kernel messages. During boot, messages can be viewed using Shift+PgUp but when the rc.S script finishes, init starts an agetty on tty1 which prints a login prompt. Then tty1 is no longer the console and Shift+PgUp cannot be used to scroll back through the boot messages. Any delayed boot messages do not have effective carriage returns so "marquee" across the screen, one following another, a line below.

Is it possible to leave tty1 as the console by de-configuring the tty1/agetty line in inittab, thus allowing Shift+PgUp to be used to scroll back through older messages and allowing proper horizontal alignment for delayed boot messages? I would try it but the inittab line x1:4:respawn:/etc/rc.d/rc.4 runs /usr/X11R6/bin/xdm and this grabs the first unused tty<n>. The xdm man page and xdm config file comments do not reveal whether it is possible to make xdm use a specific tty<n>.

Another solution may be something like the sysvinit binary that intercepts all console writes and then dumps them to log at the end of the boot process but if it were that easy or useful it would already be done and publicised (wouldn't it?).

General :: Calling Gurus And Noobs - Review Filesystem Hierarchy Explanation?

Jun 10, 2010

Back when I was first learning Linux, one of the questions that I kept wondering about was "what are all these files and directories for?" I couldn't find a resource that would explain them in a digestible manner. Specifically, I was looking for one that would allow me to look at a Linux filesystem interactively, collapsing and expanding folders to look at just the ones I was interested in at the moment. So later, when I got the opportunity, I wrote it.

But despite a ton of research, I'm still not totally knowledgeable on the subject. The most important thing I'm looking for right now is for experienced Linux/Unix people to tell me where I got stuff wrong, and for newbies to tell me how useful it is to them and which things need clarification. I'm also interested in technical and graphical ways to improve usability, like better icons, layout, etc. I know I need to be able to collapse long descriptions, but what would you like to see? The Works Cited list and a full introduction are still on the way as of this writing.

Without further ado: Linux Filesystem Hierarchy Explanation. You'll need a fairly recent browser that can handle XSLT; the actual info is stored as XML, and transformed into HTML with an XSLT stylesheet. This is still a work in progress, and I'll be updating it as the thread progresses.

Finally, would people be interested in collaborating with me on this, as an open-source project? I've never done anything like that, and I'm not sure how much time I'll be able to give it in the future, but I really think this should be continued and expanded.

Edit: Works Cited and decent intro are now in place.

General :: Boot Into The Command Line/console From Grub 2?

General :: Fedora - Boot Direct To Application On Console With No Login?

Apr 19, 2010

I have a need to start an application on bootup on the linux console and I do not have a need for any type of login or security. I do not need any ALT-F1,F2,etc virtual consoles but I would like to allow SSH access via the network port for debugging, loading, etc.

The application is a SDL graphics program running with fbcon as the SDL_VIDEODRIVER if that matters. I'm currently using Fedora 10 and 12 but any distro that supports SDL using the fbcon framebuffer would be acceptable.

Ubuntu :: Review Tutorial On Sharing 3G Over WiFi

Feb 15, 2011

I've spent some time trying to get my 3G card connection shared over WIFI and despite the number of sites out there I had a lot of problems putting it all together. So I wrote a small guide about it, but due to several issues (time/bandwidth) I can't retest it from scratch.I was wondering if someone could take a look at it and make suggestions or corrections.The idea is to take your 3G data card and turn your WIFI into an access point so you can connect other devices to it for internet access.

Software :: New Version Of Lit2PDF Script For Use/Review

Dec 1, 2010

I posted a completed version of it a while back and just wanted to post the latest stable version. I'm using it as a pet project to teach myself proper BASH scripting, but also to help my wife get .lit e-books onto her Sony E-Reader since it seems to do a better job of converting the files than Calibre(For some reason some of our books won't convert in Calibre and they will with this). I've added some zenity windows to make it just a little more friendly in regards to selecting the file you want to convert. You no longer have to drag it into the terminal window and make sure you've got quotes around it if there's a space. It's also now completely BASH instead of python. I'm a "beginner" programmer/scripter, so some review, comments, and constructive criticism are welcome because everything I know I've taught myself with Google and experimentation.

To install it, just grab the tarball, extract it, make the files executable if they aren't already when you download them, and then run the file in the terminal. I tried to be very descriptive and informative in the changelog.txt and Readme.txt files as well so I hope those suit their purposes well.

P.S. If you're wondering about the versioning, I just adopted the same philosophy as the Ubuntu community and just made the date the version number. 10.11.30 equals November 30th, 2010.

General :: Programs Run At Boot Time: Where Are They Hidden

General :: Windows 7 - Stumped By Boot Time Corruption?

Dec 1, 2010

I have a home build computer that has data corruption problems at boot time. I have exhausted all the troubleshooting steps that I know to try. Do you have any additional troubleshooting techniques that I should try?

Symptoms: I run both linux(ubuntu, mint and fedora) and win7 on this machine.Sometimes I have just one installed.Other times both in a dual boot setup. The OS installs just fine.The system runs just fine for a while.Then it fails to boot.At first I can fix the boot problems with grub or bootrec (/RebuildBcd, /FixMbr or /FixBoot) as indicated by the error messages.Eventually the system fails to boot at all and I have to wipe the disk(s) and reinstall the operating system.The linux installs seem to last a bit longer. I typically have linux running for a month before the troubles start, but I have to repave and rebuild within 3 months. The windows installs last at most 2 weeks before troubles develop. The system is turned on for the day or evening then turned off overnight.Once the system has booted all checks that I have run pass. On windows fciv.exe, sfc.exe have never deteced and troubles. On linux tripwire shows everything unchanged. Chkdsk and fsck have never reported errors.

Hardware:ASUS M3A78-EM motherboard. 2x2GB kingston memory from the ASUS QVL for this motherboard.I have used two hard disks in this system.WD caviar black 640G (WDC WD6401AALS-00L3B2).Seagate barracuda 7200.7 (ST3120026A).On some rebuilds I have used just one of the drives, sometimes I have both installed.The DVD burner is a LG 4x (HL-DT-ST DVD-RAM GH22NS30 ).The power supply was originally an el-cheapo Allied unit that came with the case.That has since been replaced with a Seasonic X650.And that is all that is in this system. I use the onboard video, sound and network. I have never plugged an external device into the system (not even a USB flash drive!).

Trouble shooting so far...I have run the memtest utility from both the ubuntu CD and the windows DVD many times. Even when run for several day neither test utility has ever found a memory error.I have run the seagate and western digital provided test and diagnostic tools on both of the hard disks. I have done this on both the unstable ASUS M3A778-EM system and a very stable gateway system.I have swapped out the HDD cables several times.I have replaced the cables with new cables and with cables pulled from a stable system.Because the corruption happens only at boot time I suspected the power supply was having problems under the extra load of disk spinup.So, I replaced the power supply. No success.

I have run the system with every version of the MB BIOS from the version that it shipped with to the latest and greatest. The BIOS upgrades made no noticeable difference.I have enabled and disabled automatic updates on both win7 and ubuntu linux. That made no noticeable difference.That is it. That is all the troubleshooting ideas I have had.

General :: Difference Between System Uptime And Last Boot Time?

May 11, 2011

My Linux system was last rebooted few hours ago. But it seems little confusing for me to figure out the exact reason behind it. I guess following command should justify what i meant to say.

# date
Wed May 11 13:22:49 IST 2011
# last | grep "May 10"
reboot system boot 2.6.18-194.el5 Tue May 10 17:35 (19:46)
root pts/1 XXXX Tue May 10 17:24 - 18:18 (00:53)


My question is Why the uptime is saying that the system is up since last 47 min.It should be more than 1 day if i m not wrong.
