Port 22 is ssh (and if you want to use it you need to unblock it in the suse
firewall).
Why do you want to use telnet it is very unsecure?

i don’t remember doing anything to set it up on my box…
you know the default port is 23, not 22…
were you told to specify 22?
what is the exact command you are using?

your linux is born with a full set of manuals, called “man” in a
terminal (do you know what a terminal is?) type:
man telnet
where you will see the full format and all the special conditions and
switches…but, barring special needs (like non-standard port in use)
just this should work:
telnet [address]
where address could be (for example) towel.blinkenlights.nl or
94.142.241.111 (both are the same place, try either
telnet towel.blinkenlights.nl
telnet 94.142.241.111
(be patient, it is all automatic but is VERY slow to progress)
both of those will default connect with port 23, or you can specify
another port (and a completely different experience) like this:
telnet towel.blinkenlights.nl 666
telnet 94.142.241.111 666
which will give you insight into the === The BOFH Excuse Server ===
which will make up an excuse for you!
Have a lot of fun, and learn to use the manual (which will allow the
fun to come more quickly)…
more questions? come back…

as mentioned earlier: openSUSE is born with telnet configured…which
openSUSE are you using?
it could be that you are typing correctly but the machine you telnet
to refuses the connection…(there are millions of machines on the net
which will refuse all telnet connection attempts)
you do know, don’t you, that the machine does NOT have to let you in…
do you have an ID and password for the machine?
does the machine owner expect you to log in?
do they want you to log in? (maybe they block everyone, or maybe just
block you)
what address are you trying to connect to (if you have one, do NOT
give your login ID/password)…JUST the address you are attempting to
connect to…

openSUSE never had a version 7, the first was 10.0…
you can learn your openSUSE version number in a terminal by entering:
cat /etc/issue
since in a computer lab,for your telnet problem try these, in order:
- in a terminal: man telnet
- consult your course text
- ask your instructor

For security reasons, I believe telnet is disabled. You should be able to
accomplish the same thing by using “ssh”, which is more secure as it doesn’t
send passwords in the clear.
tnanx . i got the version . its 11
. for consulting the instructor… I am that person. any way i had to configure telnet…I know how to use ssh and its working properly.now i have to teach telnet…
is ther any command to check whether telnet is disabled?

please instruct your students in both the basics and specifics of
this: http://is.gd/2BfI3
consider assigning that text as homework and then give a test on it…
you can make several good test questions from it …like:
- Name the seven sources in the “Before you Ask” section which your
instructor skipped prior to asking his/her question on telnet.
2: For extra credit, name or describe how you could find the seven
sources referenced using an internet connected computer. (Use your
computer to provide fully qualified URLs.)
