Does anyone know a way to list mounted TrueCrypt volumes to stdout via the command line?
The page below suggests the --list option would do it in the *nix version, but I can't find any way to do this with Windows.

I faced with same question and found solution, use forward slash symbol. Example here
In addition use "/help" key.
Hope this helps you.

Im workign to install Kafa and Zookeeper.
I have already run the Zookeeper and it is currently running.
I set up everything as in [https://dzone.com/articles/running-apache-kafka-on-windows-os]
when i finally run in my cmd,
.\bin\windows\kafka-server-start.bat .\config\server.properties
there is no output, it just moves shows the next command line started.
Please help me out.
Finally I find someone with with the same issue I had! Zookeeper running, but kafka not doing anything at all except returning to the next line with no log, error, or anything. Dunno if the cause is the same, but the solution for me, oddly enough, was to download and open cygwin, and run the command exactly as you have it, except with flipping all the \s to /s and it worked.
After lot of search this is the way I solved
You have to add in User path in Environment Variable:
%SystemRoot%\System32\Wbem;%SystemRoot%\System32\;SystemRoot%
In User %PATH% Environment variable, and not in system %PATH% Environment variable.
this question already replied on this page:
Kafka server not returning anything
Solution that worked for me:
Create the logs folder and mention it on the sever.properties, it will not create the folder automatically.
go to your cmd and run kafka-server-start.bat D:\<pathofkafka>\config\server.properties
Thanks!
Seems like a silly question, but I cannot find the kernal.js script and I think I need to edit it for my installation...(see reason below if interested, though it's not part of the question). Does anyone know where it would be located on a Linux Ubuntu system? I've tried find and grep, but not getting anywhere.
I am serving ipython notebook with a reverse proxy in front, and I am finding that the path to the kernals is wrong, causing errors when I try to load a notebook. I think this line is a problem:
var ws_url = this.ws_url + this.kernel_url;
Because it excludes the port number suffix from ws_url, which is needed as I am not using the default port with my reverse proxy setup.
I realise it would be an ugly hack to change it, but it's only for development purposes.
Check /usr/share/ipython/notebook/static/services/kernels/js/kernel.js
I am installing the MapR and I stucked at starting warden after start zookeeper on a single node.
# service mapr-warden start
Error: warden can not be started. See /opt/mapr/logs/warden.log for details
On this file there is no detail. Does anybody have a hint? Thanks =)
If you aren't getting anything in warden.log, then it's likely that the warden JVM is never even being started by the mapr-warden init script.
In some MapR versions, the mapr-warden init script will log some details into /opt/mapr/logs/wardeninit.log. You can try checking there.
However, I will also caution that currently the logging done by the init script is sparse and not necessarily user friendly to read. If you can't discern the cause from the contents of the wardeninit.log you can post them here and maybe I can help.
Another thing you can do is edit /etc/init.d/mapr-warden and add "set -x" towards the top of the file, right before the "BASEMAPR=" line, then try starting warden again and you'll get a bunch of shell debugging output on your screen. If you copy and paste that output here that should be enough to tell the root cause of the problem.
One more thing to mention, you may be better off using the http://answers.mapr.com forum as that is MapR specific and I think there may be more users there that could help.
Was configure.sh (/opt/mapr/server/configure.sh -C nodeA -Z nodeA)run on the node? Did zookeeper come up successfully?
service mapr-zookeeper status
Even when using MapR in a single node configure.sh is still required. In fact, without configure.sh warden, zookeeper, cldb and other MapR components will lack their configuration and in many cases will fail to start.
You must run configure.sh after installing the software packages (deb or rpm).
I am wondering if anyone has a Perl script (or can write one) to execute on multiple hosts at once via ssh, without any modules. I used to have something like this but cannot find it now and can't remember how it was done.
Are you looking for ClusterSSH? It's Perl, and it's used to run the same commands on several hosts at once, so this might be what you're looking for...
You might want to try using Expect.pm which is similar to #cnicutar's suggestion of calling an Expect script from Perl, except that you write it all in Perl. (This of course down not fit the requirement of "without any modules", but that requirement leads to bad Perl )
Learn how to install and use modules even when you don't have admin privileges on the host
Use Net::OpenSSH::Parallel
If you cannot use any additional modules from CPAN or any other source , all I can recommend you are:
1) Use Expect script and call it internally in your Perl script [Only if you are not willing to use Expect.pm module]
2) Use SSH keygen in all the servers to which you will connect to , so that password wont be necessary in the script. As mentioned by "cnicutar"
3) Use "remsh" if SSH usage is not that necessary.
Is there any way to bind a process / (or a thread) to a particular core in FreeBSD//Linux
I googled could not find an answer. But people must be doing it and I am surprised that the answer is not easily available
Thanks for any inputs
From the command line you can use taskset. From within your code you can use sched_setaffinity.
$ man taskset
$ man sched_setaffinity
For FreeBSD you can also consider its following counterparties
$ man cpuset(1)
$ man cpuset(2)
There's a somehow related topic on server fault to check
