So I have my new Dell Latitude 2100 (toy) on my network running Ubuntu 9.10 as delivered. I added openssh and the service is running. I can connect to the machine from another using Nautilus or Gnome Commander over ssh. However, I cannot connect from a shell(?)
ken@taylor12:~$ ssh taylor13
ssh: connect to host taylor13 port 22: Connection timed out
Firestarter shows a connection from taylor12 to taylor13 on port 22 - the Gnome Commander connection over which I am currently transferring some files.

I have a CentOS dedicated server running ProFTP. I have created user accounts which are meant for FTP access only but the users cannot connect to the FTP unless their shell access is /bin/bash
Here is an example line that is outputted when I use this command:
This user can access the FTP fine, but he can also access SSH which I don't want to allow him to do. If I set his shell access to /bin/false then he can't connect to the FTP.
What can I use in instead of /bin/bash to allow FTP but don't allow SSH?

I want to connect to an FTP server from the Linux command line. The server is configured behind a proxy.
If I call:
echo $ftp_proxy
I get a result like this:
abc.def.ghi.jkl:8080
If I call:
ftp -pn $ftp_proxy
I get a unknown host error.
How can I connect to the FTP server using the Linux command line?

Is there any way I can switch my desktop shell from unity to, say, gnome-shell? I can switch using other console shell I like (bash, csh, fish, etc.). Assume that there is a stable alternative desktop shell, I should be able to choose, too.
(For console shell, we goes to /etc/passwd. But for desktop, I can't find the way to config.)

I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.
Code:
if [ $# -eq 0 ] ; then
d=`pwd`
for i in * ; do
if test -d $d/$i ; then
echo "$i:"
code....

Is there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:
Code:
>>> import subprocess
>>> help(subprocess)
...
[pages of stuff to read]
...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.

I am using Red Hat Linux Enterprise version 5. I've noticed people sometimes running commands with a couple of & options. For example, in the below command, there are two & signs. What is the purpose of them? Are they always used together with nohup?

I was working on a shell and got some weird exceptions in my program.Just as a reference, I want to save all that is there on my shell to a text file. I do not just want the command history but also all the results that those commands produced at the shell.Is there some built-in utility to do this? I have kept the shell open for now, so that I can take the backup. Also, I am using xterm and it does not allow selecting all the way upto the top of the shell, so the ultimate way is to take the backup one screen at a time.

I've had my prompt change whenever I :sh (:shell) out of VIM, but can't for the life of me remember how?. The idea is to change the prompt to something like [SH] <your usual prompt here>, so that I know that VIM is running in the background.. I often logout of the shell, because I think VIM is open.

I've created a simple script based menu. This menu will be accessed by only a certain users via ssh.When user logs in, the menu will automatically run. (configured at user's .bash_profile).How do I force the session to close when user hits Ctrl-C or Ctrl-Break ?In a nutshell, I don't want user to have access to shell.

I occasionally use screen within linux. Every now and then my connection plays up and I lose access to the ssh shell, when I try to reattach myself to the screen instance this is what I get:
There is a screen on:
2690.pts-0.localhost (09/03/10 12:56:08) (Attached)
There is no screen to be resumed. What I could do in this case? I guess screen believes I'm still attached, while I'm not.
