General :: Why Does Changing A Truecrypt Password Take Such A Long Time
May 31, 2010
I am changing the password of a truecrypt file container. This takes around 1 minute. Why?
time truecrypt --text --change /tmp/user1.tc --keyfiles= --new-keyfiles= --password=known --new-password=known --random-source=/dev/null"
If I use strace I see that it basically does not do anything: it simply reads lots of random data from /dev/urandom (even if i specified /dev/null as random source) and finally changes the password:
open("/dev/urandom", O_RDONLY) = 6
read(6, "36&{35121221234320234313242312I326235245224300354O)270Q200 201J227224311_212367"..., 640) = 640
close(6) = 0

I have an unreasonably long time to wait from log in, to when my desktop is ready, it takes 40 seconds from hitting enter to seeing my files on the desktop, and about another 15 seconds from then to hearing the opening jingle. It used not to be this way, before it took less than 10 seconds, but about 4 days ago this time shot up suddenly, is there some way to diagnose whats causing this delay?

I am running Centos 5.3. I ran no updates, performed no installs, nor changed any configuration immediately prior to this issue. My problem is this: when I run the command startx (default runlevel 3), it is a long time (5-10 minutes) before Gnome startx, and once it does start applications will not run. Also, when I try to use sudo (from any environment, even ssh), it is a long time (5-10) before the command is executed.
I cannot say for sure, but it seems like this is an intermittent problem. Sometimes X takes a long time to start, but once it starts it will launch programs. Sometimes X takes a long time to launch, but once it starts it will only launch certain programs. Though presently X always takes a long time to start, and I cannot successfully launch any programs.
A while back a had a similar problem to this (x taking long time to start, sudo taking long time to execute) and it ended up being a DNS problem. Unfortunately, I cannot remember exactly what it was and I stupidly did not document it. Maybe this is also DNS related, I don't know.
I don't know what log files to look at for problems with X, Gnome, and sudo taking a long time to start.

I'm having trouble with Vim in any terminal emulator I use. I have a link (vi) to vim. Occasionally it will take very long to load, whether I use 'vi' or 'vi file'. Before, if I could I would restart X, and then it would load instantly again, but I waited this time and it did load, after a minute or so. Is this a problem with X or vim?

When booting Fedora 11, my system hangs for a very long time on starting udev. Sometimes I get an I/O error. However, my hardware is fine. I do eventually get in to the system.

It takes me a while to log in the splash screen just sits there for ages before i get to the desktop. Never used to be this slow and I'm not sure why. Firstly, I'm running Ubuntu 11.04, standard DE. I do have conky starting up in a script but it has the & at the end of the line so I didn't think this would cause it (or is there some special case for log in time on how & is treated?). However as a test I will comment out the line in the script and see if it is the cause.
However just for general knowledge and in case that isn't the problem, how does one go seeing what is happening during the time from when one log's in and the desktop is displayed? Is there some kind of log that shows the date/time that can be enabled or is there a debug mode that can be enabled somehow via special keys or maybe from grub?

While booting Linux it takes ages for 'enabling swap space'
I have allocated swap space twice that of the RAM.
Is there a way to fix it? What should I do to avoid this in the future installs?

we are using linux email server axigen past few years. we keep port open ssh and pop,smtp webmail etc. ssh use for remote trouble shooting. so through firewall it is globally accessable. we notice many attacks coming to our machine, also some people try to enter in our system but failure. as example see below a log come in messages file
Mar 17 09:19:50 sa1 sshd(pam_unix)[21231]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=210.51.13.120 user=root how we can secure more. as per my understanding only good long strong password can stop to prevent from attacks.

I use truecrypt to encrypt a file containing my sensitive data (credit card numbers, bank account info, etc).
When I mount my encrypted file through truecrypt, I enter the password for my file. That's OK - I want to keep it that way. But when it gets mounted as a file system, ubuntu also requires that I enter the 'su' password.
How do I get around this?
I run ubuntu 10.04 (Lucid)

Running RHEL5 and because of the environment that we are in we have to disable the users being able to change the screen saver. I have tried using the gconf-editor to see if I can disable it but don't know if that is the correct way of doing it. I also looked in /etc/xdg/menus and really don't want to miss with that.

I found a way some times ago to mount a truecrypt volume when opening the session by insertion of the login password in the mounting script instead of putting it in clear in the script. I don't remember to command to read/transfer the password.

Installed Truecrypt onto openSUSE 11.3 (KDE) and noticed that Truecrypt needed to be started as root.Modified visudo using YAST asusername ALL = NOPASSWD: /usr/bin/truecryptHowever, when copying files from my backup drive into the Truecrypt partition, there is an access problem (couldn't remember actual error message)In Konsole , updated visudo to username ALL = (ALL) NOPASSWD: /usr/bin/truecrypt Copying is allowed and working fine.Question:1. What is the difference between the above two visudo setting?2. How to updated visudo to the second setting in YAST?3. How to change the editor for visudo in konsole using nano instead of vi?

The desktop stops working, the panel stops working.. but compositing, desktop cube etc all work fine.I can still launch a program with Alt-F2.When I try and kill it (to restart) using 'killall plasma' / 'kill -9 <pid> / 'kill -15 pid' from a terminal, nothing happens, the process keeps running. If I leave it for about 30 mins it suddenly dies, allowing me to run 'plasma' from a terminal - then everything is back to normal.
If I log out and try to log back in again, I get a black screen. Only way to fix it is either to kill it and wait for 30 mins or so, or totally reboot the computer.Tail of the xsessions error file:
Code:
[/usr/bin/nepomukservicestub] Removing connection

I am using Fedora 15 KDE 32-bit. I am facing a problem while shutdown. It takes unusually long to shut down. It reaches the blue screen with the fedora logo within a few seconds, but it stays on the blue logo screen for 2-3 minutes before shutting down. However, I am facing no problems during startup.
About suspending F15 KDE. It goes into suspend successfully but after switching on after suspend, it just shows an unresponsive black screen.
Is anyone else facing the same problem and has it been solved before? Because I haven't come across many posts regarding F15 KDE.

After I installed a new hard drive, when I booted up into Ubuntu, it would give me this error: "failed command: WRITE DMA". So I tried the workarounds and I guess it just covered the log with the Boot Splash, now it's taking a long time just to boot up.
