General :: Secure Shell/terminal For Ubuntu?
Jul 22, 2010
There are a couple commands I want to run in a terminal that require me to provide my password. I really don't want those commands ending up in any kind of history or anywhere else where they could be seen by someone after the command was run. Are there any shells/terminals for Ubuntu that I could use (or options to bash/zsh/etc) that would give me a secure environment where I don't have to worry about my history being kept?

I want to learn using SSH (Secure Shell) service in linux and connect to SSH server with PuTTY to test some commands, but I have not worked with it yet;
I have Ubuntu 9.04 on my "Virtual Machine" and my host OS is Win.XP and I have installed "OpenSSH server" and "PuTTY" from the ubuntu repository,
Is this action rational? I mean I want to connect from PuTTY on linux(on VM) to the SSH Server on linux?
(Meanwhile, I have no work with the host Windows and just wanna test it on the linux!)
where should I see the "Host Name/Ip Address" of the SSH Server to enter in the PuTTy's dialog? In windows we can use "ipconfig" command to see the IP Addresses, but I don't know what is the command in linx for this purpose?
use SSH Service in ubuntu correctly

I was planning on using my VPS to grant some of my friends shells. The problem though is that I don't want them doing crazy stuff on it, like using up all my RAM or disk space. I would like to limit them to a very small 25 mb disk space, and allow them only certain application in /usr/bin like python perl irssi screen etc. I do NOT want them to be able to cd out of their home directory. I really want this to be setup like the shell provider SHellium. I can setup the FTP and SSH stuff myself.

What are the differences between shell , console & terminal?
This probably sounds like a stupid question but I'm having a lot of trouble clearly differentiating between a shell (such as Bourne or bash) and the Terminal application in GNOME. I realise that both are completely different but I can't seem to find a clear answer written in text. Could anyone clearly distinguish between both?

I have come across the use of the term terminal, virtual terminals/consoles, real-text terminals but do not understand what terminal refers to. Does it refer to the screen that is in-front of me whilst I post this question or does it refer to something specific?EDITI came across a similar post at What are the differences between shell , console & terminal? and it seems to be similar to the one I posted although am still confused about the use of the sentence Decades ago, this was a physical device consisting of little more than a monitor and keyboard. What does this device look like and how is different to a monitor?

I often have issues starting my window manager--xfce. My computer misbehaves in one of 3 ways, one of which is to fail to open X, but generate several screens of info. I want to paste that info to this site, but since I'm in the shell, not the terminal (please correct my vocabulary if it's wrong here), I don't know how to copy and paste the output, since right-clicking doesn't give me a menu. Even if I could copy I'm not sure the information would be accessible in X. Are there any other options?

I'm an Oracle DBA and started working for my current employer about 4 months ago. This past weekend an alert re: FS space brought my attention to /var/spool/clientmqueue (full of mail re: cron jobs) and the fact that sendmail is not running on our Linux servers.I'm told that the IT security team deemed sendmail too vulnerable so we don't run it.Aside from FS filling up and missing notification of issues with crontab entries, I'm concerned that we may be missing notification of potential issues. In other Unix/Linux environments I've seen emails from the print daemon when it experienced problems with specific jobs.
Are there other Linux facilities aside from cron and lpd that use email to advise the users of possible issues? Are there ways to secure sendmail or secure alternatives to sendmail? My primary need/desire is to make sure that emails regarding issues on the server get to the appropriate users. Secondary goal would be to have the ability to use mailx to send mail out. There is No need/desire to receive mail from outside.

I have a shell script that I want to be able to run from the terminal just by typing "topcat", regardless of where I am or what user I'm under. How would I go about changing the bash configuration files (if I have to) in order for that to work, for me and for the other users on the computer (I have root access)? As it stands right now, I have to type "/bin/topcat/./topcat" in order for it to execute

I've seen lots of posts all over the Internet that advise users to check the "Run command as a login shell" checkbox in GNOME Terminal under Edit->Profile Preferences->Title and Command.
This makes gnome-terminal run bash/csh/tcsh/ksh as a login shell, which it does not do by default. In turn, running gnome-terminal as a login shell sources the system and user login scripts. This sets up things like colored ls etc.
It seems like gnome-terminal should be a login shell by default. Why isn't it? I've never seen a good explanation of why gnome-terminal isn't a login shell. The "Run command as a login shell" checkbox must be unchecked by default for some good reason, right?

I am trying to use Ubuntu terminal to execute unix commands. However, the dollar sign that usually appears in shell terminal is missing. Please see the attached screenshot image showing the terminal without the dollar sign. I cannot run any unix commands like cd, ls-l. Please advise how I could fix this problem.

In a shell script. And use that in a condition.
Something like:

I just installed Ubuntu 10.04 for some development. I was trying to set some environment variables are noticed that when I hit 'set' inside a terminal (to dump environment vars) I get the usual first few variables but then I see a whole lot of script code ....
Code:
WINDOWID=23068675
XAUTHORITY=/var/run/gdm/auth-for-sid-5IDovs/database
XDG_CONFIG_DIRS=/etc/xdg/xdg-gnome:/etc/xdg
XDG_DATA_DIRS=/usr/share/gnome:/usr/local/share/:/usr/share/
[code]....
I've installed a lot of tools (NetBeans, Ruby, Java, build-essentials etc) but essentially I installed Ubuntu today - so it shouldn't have rotted out this quickly. is this hijacking of environment vars to embed script code intentional with Ubuntu 10.04?

i've finally got a NIX environment...yipee! Installed opensuse 11.2 in a dual boot with windoze with no problem whatsoever. unfortunately, my NIX skills are sadly dated or maybe things have changed or both. in any case, i have a rather trivial problem that i have not been able to figure out.
i go to gnome terminal to get to the bash shell, no problem except when i do things like cat, less and so on. the commands do what they do then when done the last line output is "some text" and "(END)" - at the completion of the command it does not return to the bash shell. i've tried ctrl-everything, enter, escape, actually all keystrokes i can think of to get back to the bash shell...no luck. man and docs have not been helpful or i simply missed the answer (i'm a little saturated at this point).the only thing i've been able to do to solve my dilema is close the terminal an start a new instance, not elegant but works.

I've created a brand new CentOS 5.4 (Final) 64bit machine AMI on Amazon EC2. This was based off an existing image. I was able to follow the wiki to add NX server. I am using WIN XP desktop for NX client.
I can connect to the EC2 machine and get the GNOME desktop fine. I see the usual CentOS desktop and poke around.
Q/Problem:
I expected to open the Terminal window and get a shell prompt to su into root user (I need to be root to install some software that needs GUI). I do not want to install this from my plain SSH connection to EC2 (hence the NX server etc.).
When I open the Terminal window, all I get is the NX>105 prompt. I need to get to a shell prompt so I can su into root. For life of me, I cannot get around this prompt (I looked at NX documentation too). Note that this is a prompt NOT on client but on the remote machine. I do not need this as I'm already authenticated and logged in to remote GNOME desktop.
Obviously the TERMINAL is running some NX start up script (I've no idea which one). If there is some other way to sudo into root?

I am running a Java application on the command line bash terminal under Mint Debian. I have JDK1.6.0_22 installed 64-bit, and the OS is 64-bit too. I have a few JAR files in the directory and a few native LWJGL libraries. When I run the application using the command line, all works fine.
Lets assume my directory where the files are is called /home/riz/MyGame. I change to that directory and this is the command I use code...
