Software :: Tripwire Reports Huge In Size / Reduce / Prune Them?

Jan 21, 2009

I have been asked to investigate some of our servers that run tripwire 2.3.0 on Red Hat Linux Advanced Server release 2.1AS (Pensacola)

We have the reports emailed to us using cron and twprint -m r -r report -t 4, it has been growing steadily and today it was 9mb It seems the database records go back to before 2004 and are being compared against today's files.

I really need to be informed what needs to be done to tripwire to keep it serviced through cron. I have tried to google this but could not find any information that seemed to answer my questions.

Looking at the following guide url step 6 talks about "Updating the Database after an Integrity Check" using

# tripwire --update --twrfile /var/lib/tripwire/report/<name>.twr Should I be using this command or should I be re-creating the db every month or so and using the #tripwire -init?

Extract from report -


Section: Unix File System

Rule Name Severity Level Added Removed
--------- -------------- ----- ------- --------
Invariant Directories 66 0 0 0

I need to understand how to change the expected to the observed so the db will be up to date.

I would also like some of the rules explained:What does removed and added mean? Is it removed as it has not changed and added if it finds a new one that has?


Rule Name: System boot changes (/lib/modules)
Severity Level: 100
Added Objects: 3075

Server :: Reduce RAID5 Partition Sizes / Reduce The Size Of Md1 And Grow Md0?

Feb 14, 2010

I have a rack of four 1TB drives all partitioned identically with three primary partitions. On each drive

- the first partition is only 64MB;
- the second is a large 900GB partition and
- the last holds all the remaining space

mdadm has been used to set up
/dev/md0 - RAID1, comprised of /dev/sda1 and /dev/sdb1
/dev/md1 - RAID5, comprised of /dev/sda2, /dev/sdb2, /dev/sdc2, /dev/sdd2
/dev/md2 - RAID5, comprised of /dev/sda3, /dev/sdb3, /dev/sdc3, /dev/sdd3

OK, so it was a silly mistake to make - but I am now need to increase the size of /dev/md0. My thinking is to reduce the size of md1 so that I can grow md0.

On md1 I have two logical volumes. I've successfully reduced the size of the volume so that I can reduce the size of md1. Now I'm at the nervous stage; I can find little written on the topic of shrinking RAID5 arrays - and even if I do this I'm unsure if I can move partitions around to regain the space I so desire.

Fedora Security :: Tripwire Revealed File Size Differences?

May 14, 2009

Recently I decided to utilize an IDS system. So I installed Open Source Tripwire. Not that I am too worried about anyone gaining a successful foothold on my system. But I wanted to learn and experience this IDS system. And no, this is not a new server install but I have never seen anything that resembles illegal activity. My server is an installed CentOS 5.3 with SELinux in targeted mode.

Tripwire has brought to light some interesting things. Installation states to verify rpm packages using rpm -Va. I have found that many of my system binaries are not the same size as if I were to replace them via yum. Most of the binaries are like twice the size compared to a newly installed package, of the same version. I'm not sure what to make of this. These programs are the original installs (CentOS 5.1) and I keep the system up to date regularly via yum.

I wonder if perhaps these system files installed are perhaps different then individual package size installed via yum? I have a hard time believing this as a package is a package. The only other possibility that comes to mind is that nearly my entire system has been hacked with new system files, and in a way that has revealed and suggest nothing. I find that far fetched as I have run this server for some time now and I should think I would know a problem as not a morning goes by that I haven't review my logs, as they are emailed to me. Thoughts about the difference in file sizes? Those installed via CentOS DVD verses those installed via yum?

General :: LV Reduced In VG Now / Reduce The FS And Partiton Size Of The PV?

Oct 18, 2010

I have a HDD that has 2 partitions. the 2nd partition is the VG and I want to reduce its size. I have reduced the Largest LV in the VG and now have free space in the VG. But, I am clueless on how to proceed to reduce the partiton size so that I can use it for another need.

When done, I expect to have 3 parttions total on the HDD. But first, I could some help in understanding the steps necessary for me to take, to move the free space out of the partition that has the Volume Group. Then, i can use fdisk on that 3rd partition for my needs.

I already know how to expand a Volume group by adding PVs, but, I do NOT know and cannot find how to reduce it to recover the free space in the VG to be used in a new partiton. (Better explained..."I want to reduce the physical partition size that the VG represents.)

General :: Reduce /var Filesystem Size - Impact?

May 10, 2010

I need to create a temporary Filesystem and the only way to do it is to reduce /var and create a new filesystem 3GB size

df -h
9.7G 1.5G 7.8G 16% /var

my question is according to google search I need to umount the filesystem point in order to reduce its size.... so it means I will require that nobody uses the system? since /var logs a lot information?

I also have the option to reduce /root but I think is more complicated.

so what are the precautions in order to reduce /var/?

Debian :: Reduce Swap Size On Encrypted Drive?

Apr 30, 2016

I installed Debian 8 Jessie with full disk encryption and chose to have everything on the same partition. After install, I notice that my 8GB laptop has a 16GB swap. Is there a way to reduce the swap to 8GB (or maybe 4) whilst not affecting the encryption?

I have a 1TB HDD so space is not an issue but I dislike such waste. The setup used LVM.

Ubuntu Multimedia :: Reduce Avi Video File Size?

Jun 7, 2010

I have rendered out less than two minutes of High Definition animation to Avi-Jpeg Format in Blender. Now, I have this 2 GB file. Going at this rate, it's going to take a whole DVD set to play a 15 min movie.

Surely, this file doesn't need 2 GB just for 1:45 min/sec, right? Even at high def? How do I reduce this file size down to like a manageable number, say, 20 miB?

Ubuntu :: Reduce Desktop Window Size Within Screen?

Aug 23, 2010

Can the size of the Ubuntu desktop window be reduced so that it displays on a monitor or via a data projector with a surrounding black border? If so, how? The tragicomic chain of events which leads to the question is as follows. Community group, short of cash, want to equip lecture room. Pull-down screen is set up permanently on one wall. Contractor sets up old data projector via ceiling mount. Data projector is just too far away from wall, such that image cannot be reduced sufficiently by the data projector to fit on the screen.

Annoyingly the image, as displayed, is only slightly too large - just enough to lose the top and bottom panels, Applications menu, File Menu on full-size windows, Indicator applet, Trash, and restore desktop button. The data projector is hooked up via VGA cable to a recycled PC running Ubuntu 10.04 with proprietary NVidia driver (version 173) for GeForce 8400 GS. I'll give anything to be able to do this on the PC, rather than having to move the projector!

General :: LVM2 On F10 - Reduce LVM Size And Remove 2 HDDs?

Oct 15, 2009

I have the following HDDs in an LVM2 configuration on an F10 box running Mythtv :-

# pvscan
PV /dev/sda2 VG VolGroup00 lvm2 [297.88 GB / 0 free]
PV /dev/sdd1 VG VolGroup00 lvm2 [931.50 GB / 0 free]
PV /dev/sdb1 VG VolGroup00 lvm2 [298.06 GB / 0 free]
PV /dev/sdc1 VG VolGroup00 lvm2 [931.50 GB / 0 free]
Total: 4 [2.40 TB] / in use: 4 [2.40 TB] / in no VG: 0 [0 ]

The system never uses more than about 250GB of HDD at any one time, so I would like to remove /dev/sdd1 and /dev/sdc1 from the LV and then from the machine and leave /dev/sda and /dev/sdb alone.

Does anyone know that if I use the command "system-config-lvm" to reduce the total LVM size to say 580GB, whether all data is preserved (I don't have any way at this stage to backup up 250GB of data, unless I buy more HDDs and that is the whole point of this exercise anyway - remove the two terrabyte drives to be used as backup disks).

Once I am happy that the data is safe, I will use "pvmove" and "vgreduce" to remove both terrabyte drives.

Ubuntu :: Nautilus Font Size Gets Huge In Listview

Jun 6, 2010

When zooming to 100% in listview the font gets huge, but only in the listview panel (see image). Where to reconfigure this to normal behaviour (I'd like the 100% fontsize to be the same as in the treeview in the left panel). I had this behaviour already with the previous relase of Ubuntu, and upgrading to 10.04 did not solve the problem.

Ubuntu Multimedia :: LSPCI Reports Wrong Video RAM Size

Jun 11, 2010

I am running ubuntu 10.04 with the fglrx driver installed with apt-get. I have an ATI Radeon HD AGP with 512MB of video ram. My bios window size is 64MB. The Xorg.0.log file shows that 512MB is recognized. I also tried checking the /proc/mtrr file and it shows two values one I believe is my ram size which looks to be correct at 1.5GB the other is 512MB which I think is my video ram size, but when I do an lspci -v the video ram size shows 256MB. I am trying to run Doom 3 and it only allows me to use 256MB of memory.
