Subject: secure telnet through gateway
Date: Fri, 07 May 1999 01:35:07 GMT
Can I restrict a user on a LAN-connected linux workstation (machine A)
to telnetting to one other workstation (machine B). And nothing else
within either machine A or the LAN.
The objective is to give a remote user telnet access to machine B.
Machine A is an internet gateway. Machine B has no direct internet
connection. I have a secure way (ssh) to give the remote user command
prompt on machine A (as if he were telneting to it). He thus becomes a
user of machine A, under his own user account. From there he can run
his telnet to machine B.
But I don't want him to launch any other activities from machine A. He
should be quarantined from machines on the LAN other than B. And he
shouldn't run, or read, other stuff that's on A. Just telnet to B.
I thought maybe a permissions solution could work. Putting a copy of
telnet in the user's home directory for him to run, with execute
access on the directory but not read access so he can't put copies of
any other executable there. Then deny him the ability to execute
programs anywhere else in machine A's directory tree. I experimented
with permissions but it's harder than I thought.
Any way to confine this user, or other ways (firewalling or port
forwarding or something) to get the remote user securely telnetted
into machine B?

Correct behaviour.

To be honest ... my first option would be to rewrite the server so it
does not abort, my second just to wait and the third depends on your
kernel release. 2.2.x has some tuneable parameters (via /proc) and
see /usr/src/linux/Documentation/networking/Configurable to start
with.

I had a similiar problem but with just ppp-compression. Here's what was
suggested to me that fixed it not sure about net-pf modules though.
in /etc/modules.conf:
alias ppp-compress-1 off # This is Predictor-1, not yet supported
alias ppp-compress-2 off # This is Predictor-1, not yet supported
alias ppp-compress-21 bsd_comp
alias ppp-compress-24 ppp_deflate

Simple enough. Just boot up as single user. There's an option for it in
your /etc/inittab file. If you want to change it permentantly, look for
the lines that describe which modes do which. Then there's a line that
reads:
id:5:initdefault:
This sets your initial default runlevel. Change this to match what the
runlevel is for single user, save it off, and reboot.
Now, as for *WHY* you *DON'T* wanna do this, if you boot in single user
mode, you boot in as *root*. You can do some *SERIOUS* whackoness as root
that you *can't* do as any other user. Like, delete your /lib directory
if you're not watching closely.

Reply-To: "Georg Cantor" <[EMAIL PROTECTED]>
I have recently installed RH 5.2 linux linked to Win 98 clients.
Whenever I run telnet from the Win98 clients, I get a blank screen. Nothing
actually happens, the cursor just stays in the corner.
I have checked the inetd.conf file and telnet is enabled. Running telnet on
the server itself seems to work, although I am not familiar with manual
telnet commands.
Is there some way telnet is disabled from accepting incoming connections or
what?
I need some info on setting up a working telnet configuration. Where do I
start?

Hi,
I have posted numerous times, and haven't gotten a response, so I
figured I would try yet again.
I am going to be running a LAN (Linux box serving Win95/98 clients all
in Private Class C IP address space). The linux box will be used to
connect to my ISP via PPP each time a client needs network access. How
do I do this? What if another client has already caused the server to
open a dialup session (i.e. can the two clients share the PPP connection
that the server has established)? What services will I need to run?
Firewalling? IPmasq? DNS? How about using the linux box to get our mail
from the ISP regularly, and then have clients connect to it to get their
individual mail?
Thanks in advance,
Matt

You said it runs in Windows. Is you modem a winmodem, cause if it is then you will
never get it to work under linux. If it is not then I suggest typing cat
/proc/interrupts and cat /proc/ioports to look at what devices you have free. If
it is not a winmodem check to see if you can configure the setting i.e. IRQ COM on
the modem itself. Have you tried using the setserial utility. I have to use it to
set my modem to IRQ 5. I type setserial /dev/ttyS2 IRQ 5. I am using RedHat 6.0
so I have to use ttyS2 for my device. Under Redhat 5.2 and earleir I hade to use
/dev/cua2. Let me know if you have any luck.

If you know how to use the automounter on Solaris, you know how to use
it on linux. The structure and location of the map files is the
same. Make sure you build autofs support into the kernel, and start
the autofs service on boot.

Chris,
You can type the following commands to resart certain services
/etc/rc.d/init.d/network restart
/etc/rc.d/init.d/smb restart
stop and start can be substituted for restart. smb is for samba file
and print sharing. Hope I helped.

Chris,
you have to replace samba with smb. I know it is not intuitive but it
is what the programers did. Hope I helped.
