General :: RHEL 4.6 - Cannot Boot Pass Starting Auditd
Apr 15, 2011
I'm using RHEL 4.6. auditd was set on for run levels 1-5. I changed something (?), now my system won't boot. It hangs on "Starting auditd:". I tried adding "enforcing=0" to GRUB. I tried adding "selinux=0" to GRUB. I tried adding "auditd=0" to GRUB. I've tried them separatly, as well as, in various combinations. I've tried entering "I" to go into interactive mode but, I'm not fast enough to hit that millisecond window. How can I skip/get pass the "Starting auditd:"?
I have an issue that is fixed by changing the lpfc driver to run using MSI interrupts. This is done by adding "options lpfc lpfc_use_msi=2" /etc/modprobe.conf.local file.
Is there a way to make this change using kernel boot parameters?
I have one distro installed, LILO as the boot loader, and i wonder if it's possible to duplicate the lilo entries with an option which executes some script or command during, or after the boot.Actually, i installed a Slackware + autolaunching virtual machine, but i have two VM, so i need to autolaunch one of them. May i choose it from the very beginning ?
Its basically an old SATA Hard Drive with a Windows XP partition I was trying to sell.When my computer does the BIOS checks, it doesn't pass the SMART test (but I can boot it anyway), although I can't boot Linux in any way with this Hard Disk connected (I even tried Live CD distros, like Parted Magic).I can boot the XP partition from inside the disk, although I guess its pretty close to not being able to. Is there any way to "fix" this Hard Drive?
I have 4 partitions in my system, out of which two(sda1, sda2) have windows on them. I have installed RHEL 4 32 - bit on sda3 and after that , installed installed RHEL 64-bit on to a partition sda 5. Now i am unable to boot into RHEL 32-bit. The error i am getting is Error 13: Invalid or unsupported executable format.
I have Ubuntu 10.10 installed on my pc with XBMC installed. It's set to boot into xbmc on start up and works fine. I also have squeezebox server (a music server for my network) installed and again don't have any trouble. I'd now like to get squeezeslave running, a client for squeezebox server so I added the following lines to /etc/init.d/local:
I've installed RHEL 5.3 on a Dell Desktop. I don't want to install GRUB to the MBR. Is there a way to boot up RHEL from a floppy?I've installed GRUB on to a floppy but not having much luck starting up RHEL. In the past Slackware has allowed me to startup the kernel from a floppy using LILO. I was hoping that there is way for RHEL too.
shut down my RHEL 4 system with an error still present in the /etc/fstab file. Current symptom: When I now try to boot, everything hangs when "Enabling swap space". Highly likely, the reason is the failure to "Mount local filesystems" in the previous step (i.e. "mount point 0 does not exist" = error due to my incorrect line in the /etc/fstab file).Question: Is there any way that I can still boot my system, such that I can remove the incorrect line in the /etc/fstab file?
trying to triple boot XP, Ubuntu, RHEL 5.4but unable to bring every thing in boot loader.* It loads XP with Ubuntu successfully or XP with RHEL 5.4 but not all the three.* when I install XP followed by Ubuntu then RHEL, I am not having a primary partition to install RHEL. It stops there.* I tried to copy the kernel path of ubuntu from grub.cfg in ubuntu and tried to edit in grub.conf file of rhel and added an entry but it displays in boot loader [start screen where it displays all OS listed] but unable to boot ubuntu [unable to load ubuntu kernel].Current situation reformat all Linux partitions and installed Ubuntu with below partition. installed successful. But rhel not installed due to error.Partition table:
/dev/hda1 > XP [primary patition][can boot and work] /dev/hda2 > Ubuntu [primary patition][can boot and work] /dev/hda5 > swap for ubuntu [secondary partition]
I am running RHEL 5 on Vmware Workstation. That is i inslled Vmware Workstation on windows 7 and then in Vmware i installed RHEL 5 as a virtal machine. By mistake i made some wrong entry in my /etc/fstab file that is i was trying to automatically mount one folder under another folder. My syntax was wrong. So when i restart my RHEL 5 , at the boot time due to wrong entry in /etc/fstab system is giving file system error as follows:
Checking filesystems fsck.ext3: Unable to resolve 'LABEL=/home/download' fsck.ext3: Unable to resolve 'LABEL=/var/ftp/uploads' [FAILED] [code]....
So right now VNC is starting a session using :1. When I connect to that session, the terminal is logged in as root. I'd like for the terminal to be logged in as a different user as some of my end users are going to be using this and don't require such privileges. I found that I can "su" to a different user and start a new VNC daemon on :2 and when I connect to that session, the terminal is logged in as that user. What I want to do is get that to run at boot-up.
Environment:RHEL 5.2 and 5.4 AP x86_64, 2 drives (sda, sdb), installing without optional features like clustering and virtualization. I have tried this for a couple of days now and just can't get it to work. My goal is to take the RHEL 5.2 DVD and RHEL 5.4 DVD and install them on separate drives of the same machine. I want the grub menu to give me a choice. I prefer to understand the steps and choices offered me by the install dialog to do this rather than fiddle with grub.conf. If that is not possible, I will write up the bug.
So far, I just get the the error 13 when trying to start the grub added second OS. I have read elsewhere that "Anaconda frequently recognizes the other operating system and sets up grub so you can boot from either operating system". That would be nice. The install dialog lets me choose a drive to install to. I have figured out that I need to check "review and modify partitioning layout" to enter the advanced grub choices. Do I have it install a boot loader for the 1st OS? Trying to add the 1st OS during the second OS install creates a grub conf with no kernel line in the added boot stanza.
I would like to create an alternative booting possibility in my GRUB menu that does not start some services (listed by chkconfig) like cups.
I would use this boot during travel where I surely does not need these services and shorter bootup time is preferable. Permanent removal of such services is not an option because I could not miss them during normal daily work.
i wanted to know how can I make my programs or script automatically start at boot time ,for example if I restart my server at any time they start at boot time automatically with no need to any body to start them.
I want to monitor a part of my filesystem for changes, including file opening and attempts to open files/dirs without necessary permissions.Since every read/write/open is run by syscalls i figured that running the auditd would be the simplest way to do this. I installed auditd and added a rule:
Code: auditctl -w /srv -p warx However I do not get any writes reported via ausearch -i. As a simple example, if I run
can not ping from host (RHEL 6) to RHEL 5 in (virtual)? I have stopped iptables on both machines. But still not able to ping from host machine to virtual.
Anyone can tell me how to enable and config auditd in linux kernel 2.6.9-5.EL. I have only found command auditd and auditctl in server that run kernel 2.6.9-5.EL. I ran auditd & and can saw auditd ran in my server. But I couldn't do anything with auditctl, no status, no rules, nothing :| . I tried to find audit.rules or auditd.conf but that nothing I can find.
One day I turn on my laptop and everything is starting up normal I get to the screen that shows Ubuntu loading then it changes to Nvidia Bata screen then back to Ubuntu loading then back to Nvidia. It wont get past that part.
I have looked on Google and and tried many things like:
-dpkg-reconfigure xserver-xorg, and sever different varies of it. I read that I should get another screen to pop up. Non of that happens and still the same problem.
-I tried to boot with the live ISO and
mkdir /mnt mount /dev/sda5 /mnt chroot /mnt dpkg-reconfigure xserver-xorg reboot that didn't work either.
-I went into recovery > failsafe and it kicked me out back to the recovery mode menu.
way to redirect the audit daemon message to a remote host I checked the auditd.conf and it's man page and find that the log location is specified by the line log_file = file_path and in the man page
Quote:
"log_file: This keyword specifies the full path name to the log file where audit records will be stored. It must be a regular file."
does this mean that the auditd does not have the function to redirect the logs to a remote hosts.
Old Toshiba laptop model A30 -- tried various installs 8.04/9.04/9.10. They all hung trying to boot the install disks after the initial few screens. Finally, I got 9.10 to install, dual booting XP and 9.10 by choosing F6 from the initial menu, and putting an X beside:
ACPI=off noapic nolapc edd=on nodmaid
and then hitting escape.But, after the install, I couldn't boot 9.10 from grub as it hangs after about 30 seconds of trying. The live CD would not work without the above parameters being set as described above, but does work with them set! I need those same parameters passed to grub at 9.10 boot time, but I can't figure out how to do that. I've had many successful installs of Ubuntu across a number of desktops and laptops, but I never had to deal with the guts of grub before. It all just worked.
I am trying to download RHEL 5.4 AS version for testing..But under [URL] There is no specific link for AS version or ES version..How can I detect which iso is for AS and which one for ES..? There are separate links for AS and ES version for RHEL 4.x version but why is it not available for RHEL 5.x versions?
I'm trying to configure auditd to monitor "strange" events with apache2 weberver on Wheezy (though same problem occurs on Jessie), tried both with "vanilla" 3.2 and backports 3.16 kernel I am actually using.
Here's auditd rules I have problem with:
Code: Select all-a exit,never -F arch=b64 -S stat -F path=/var/www/server-status -k web -a exit,always -F arch=b64 -S stat -F uid=www-data -F success=0 -k web
So to recap, I want to log stat syscall failures for www-data user, but excluding some "known" issues, such as that "/var/www/server-status" (after a2enmod status, /server-status path can be accessed for statistics, though apache2 still tries to find physical file for that path and fails).
I am facing a problem with my AT91SAM9260 customized board. Board is almost same as the evaluation kit.
I could download the binaries ( Bootstrap-v1.16, u-boot-1.3.4, linux kernel 2.6.20) successfully to the DATAFLASH/NANDFlash in my board by using atmel SAM-BA tool with usb/serialport/jlink.
Here I describe the problem.
When I power up the board, boot strap is not jumping to U-boot location, in the normal boot sequence and board stuck with bootstrap.
But when I disconnect/connect the JTAG USB cable ( provided with SAM-BA ICE) , it's jumping to u-boot location and booting the board properly. I'm getting the same error in NAND FLASH also.
I have tried one more test case.I copied bootstrap binary at the flash location, [location which is specified for u-boot binary] instead of U-boot.bin (location: 0x8400 in dataflash), I got continous bootstrap debug messages in my console. [ So can I conclude SDRAM doesn't have any problem? ]
i have old RHEL 3 system which has kernel 2.4 installed into it. I wasnt to upgrade it to RHEL 5.x so i downloaded a kernel 2.6 package but was not able to compile it.
passing a wild card array to cp, I know it can be done but cant figure it out, ive got 3 files all start with the word somefile but have 3 different extensions
somefile.conf somefile.dat somefile.py
there in a folder with a bunch of other files and I just want to copy them to a different location. I remember is being something like cp somefile.[py conf dat] /somewhere but this isn't working Ive searched the net and can't find it with the keywords i'm using.
processArgs $* If I call this script with Code: ./script first second third it'll print each of the argument on a new line - exactly what I would expect. However if I call it with
Code: ./script "Single Argument" "Second-Argument" it splits the first argument in two using the space as a delimitor. The problem appears to be the call to processArgs, where $* doesn't honour the quotes around the variables sent to the script.
