General :: "rpm -Va" How To Interpret Output ?
Sep 8, 2010
To understand the output of rpm -Va on my server?
The last few lines look like this:
Code:
I know that "c" means configuration file.
The man page explains the other codes
Quote:
But here's my question. Should I worry about rpm reporting so many file changes? And is there anything I should do?
This is a dedicated server. The host reformatted and reinstalled the software on August 24. A lot of the listed files are like this:
It looks as though the files weren't pulled from the repository but installed some other way by my host?

I'm having trouble with a bash script. I have something like this:export VAR=`command`The problem is that "command" can return this: "** NONE **". bash will then replace each of the * by the list of files in the current directory.I want the output to be uninterpreted (i.e. VAR should contain "** NONE **", not "list of files list of files NONE list of files list of files"). It shouldn't be hard but I am unable to figure it out, and I'm not sure how to phrase the problem,

time a.out
106.130u 0.000s 1:46.28 99.8% 0+0k 0+0io 83pf+0w
As per my understanding of the man page:
the first value is the time since the code execution started and ended,
the second values is the time spent in usermode
the third one being in kernel mode
Is the 99.8% indicating time spent in kernel mode?
Also, what does this indicate?
0+0k 0+0io 83pf+0w .
The program definitely takes more than a minute to execute - then why is the first value so small?

I've got a system that is maxing out CPU. Running "mpstat -P ALL 3 5" shows the following.
Quote:
08:30:21 PM CPU %user %nice %sys %iowait %irq %soft %steal %idle intr/s
08:30:24 PM all 100.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 1001.00
08:30:24 PM 0 100.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 1001.00
[code]....
All 5 groups show the same. My first question is why would CPU0 be the only one with intr/s and the others do not? Info.The OS is RHEL 5.4 running as a VM on ESXi 4.1. Memory doesn't appear to be an issue, the system has 8 GB and its only using about 1.5 GB. Second question, I'm positive the process that is the problem is the tomcat process. Does anyone know a good way to see whats happening with a specific process?

I am using Linux as my OS and using TOP command to measure the system performance. From the readings using the TOP, I have observed the following
(1) The used memory increase significantly from 7% to 99% over sometimes? Is there a sign of memory leak? Does OS play a part in used memory? Will system performance be affected? Will system crash due to 99% used memory?
(2) What is the difference between Memory Buffers and Cached?
(3) From the readings, it was observed that Buffers readings decrease, whereas Cached readings increase over time.
(5) Should TOP be used to take readings for system performance (memory & CPU usage)? What is the recommended method to take readings?
Whereas, my applications only consume a bit of memory and CPU.

I access a linux server shell via putty, but many of the keys I use do not translate across, up, down, left and right all are seen as ^[[A, ^[[B, ^[[D and ^[[C; But so is C-up, C-down, C-left and C-right. And enter is seen as C-j (which move down to the next line), and backspace is seen as C-h, which is backwards delete.
How can I stop these keys being translated into other keys (so I can, for example, configure C-h and backspace to perform two different functions) and what's doing this translation (Putty, the kernel, the shell)?

5. What key quits the more utility and displays the shell prompt?
6. What command starts a child shell as the super user, taking on root's identity and environment?
7. Which wildcard characters can be used for searching all the files in the system that start with "A"?

Ah, this time you've really screwed it up without covering you traces: F14 does not interpret correctly my (possibly botched up) ACPI tables and HANGS!!! With acpi=off I have to press the power button to switch my desktop off and that is really ANNOYING. Surely the Fedora engineers could have done a better job with this one.

It looks like I have one hard drive (30 GB) with three partitions, but df says my primary partition is under 9 GB? Shouldn't it be much larger?
Code:
$ sudo fdisk -l

255 heads, 63 sectors/track, 3649 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I've got rkhunter installed and regularly do scans immediately before & after updates & if I get warnings about 'file property updates' after the update I use 'rkhunter --propupd' to give me a clean run.I'm about to setup a ubuntu computer for my nan, I want to enable automatic security updates so she doesn't have to do anything to keep her system secure. I was planning on running rkhunter when I go to her house (about once a month) and check the dates in the resulting rkhunter.log warnings with those in the var/log/apt/history.log to see if legitimate updates caused any rkhunter warnings. I've noticed though that the 'Current file modifiation time:' in the rkhunter.log warnings are incorrect.
My system seems to be about 15 days behind the actual date, I've now run rkhunter --propupd so I have no warnings but got this one off another forum post to show what I mean:
Current file modification time: 1283341157 (01-Sep-2010 06:39:17)
I believe that the '1283341157' is the time in some strange format and the date in brackets is what rkhunter thinks it might be in human format.
1) How to interpret the 'strange date format' (1283341157 in the line above)?
2) If there's a way of configuring the date in rkhunter so that they're correct in rkhunter.log?
3) If there's a better way of keeping her system up-to-date & secure, it's her first computer & she's 86 so I think setting up automatic security updates is the way to go, it'll be one less thing to overwhelm her!

I used to configure and run PHP script in Redhat Linux System for a long time ago. Now I forgot almost everything in Linux. I downloaded and install Fedora 11 Live CD. Start httpd service(Appache). It does work with html but not PHP script. And I can't remember how to configure the system to interpret PHP script.

GNU assembler 2.17 And without having to prefix them. I'm skimming through as info page and can't find any pseudo operator or assembler directive of this type. E.g. 74 would be a decimal number. But I want it to be hexa 74 without the need to write 0x74.
NOTE: as is the GNU assembler.
EDIT: Google led me to discover this:
Quote:
If you write numbers without an explicit indication of the base, the most recent `.RADIX S' command determines how they are interpreted. However, on the one hand, it says the most recent and, on the other one, it applies to GASP, the GNU assembler preprocessor. IDK if it is the same as as (the GNU assembler).

I recently bought a Lexmark Interpret S405 printer, and the box says that it's compatible with ubuntu. I downloaded the lexmark-inkjet-09-driver-1.0-1.i386.rpm.sh, which begins installation but gives the error message The installer package is not supported by your native packaging system. The installer will exit. I also downloaded the Linux_S305_E.sh, which doesn't even begin installation. PLEASE HELP, I have two brand new Lexmark printers, (the other being an X5630) and they both refuse to install or i just have no idea how to install them.

I finally got audio working on my ubuntu 9.10 desktop... now I am having sound issues watching movies from a network share.The sound device continually randomly changes to "dummy output device" and then there is no sound output. The sound icon dissapears on the toolbar. To get it back and audio to start working I have to $sudo alsa force-reloadIt seems to happen everytime there is a network delay, the movie will stop for a second and then when it plays the sound is gone

I've been messing with a curses-based disk check tool in Linux called VDT (visual disk test). It puts out a nice little chart on the screen as it's going, but I have no idea what each unit of output on the chart means. I've read the man page several times, but there doesn't seem to be any mention of the visual output.
For instance, right now I have a chart that looks like this during a read test. What do the o's and the Z mean?

Usually to view individual cpu % we press '1' in the interactive mode of top.
However I am not able to figure out the logic to get the same output in batch mode i.e,
top -n1b
I am redirecting this output to a file to view it later and stuff like that, so I need the batch mode. Is it possible? Installing a separate tool for this is not gonna be possible.
I'm looking for an option that I am missing or some way to capture the output.
