Telnet Session Welcome note ???
Hello!
I wanted to ask you how to properly set the BANNER variable in the /etc /default /telnetd file, as a welcome note. For example, when I set the following in the file:
BANNER="SunOS 5.9, Solaris9"
The telnet session welcome screen then shows:
SunOS 5.9, Solaris 9 login:
Now I want that this login word appears after at least one or more lines, like this:
SunOS 5.9, Solaris 9
login:
Please help me out, how to set the BANNER variable properly spanning over multiple lines.
Hi,
Banner variable I've not set this ! instead i've created a file with necessary inputs saying "Bla Bla access restricted so on " maka shure u add this file to the /etc directory file name is issue " /etc/issue" the contents of this file would be displayed if any 1 connects through telnet, it can be used as a welcome message as well as a warning to potential guys who play around by adding a line saying Ur activity is being logged.
Cheers

If you need to insert control characters in vi such as line feed or carriage return you must type Control-V then the next Control character for them to be recognized as control characters.
<Control-l>=linefeed
<Control-m=Carriage return
<Control-g=Bell
In your case it would be:
<Control-v<Control-l><Control-v><Control-l><Control-v><Control-m> -

Getting welcome note from session
Situation:
following a successful login the users NAME is stored in the session object:
code:
session.setAttribute("PetStore_Name", new String(customer.getName().toString()));
then the login page is redirected back to the Default.jsp where i want a welcome note to be displayed
if the user has loged in / or the session object containing the name is still valid from previous login then the welcome note should reads
WELCOME JOE
if not loged in then welocome note should reads:
WELCOME TO THE JAVA PET STORE
code:
Welcome <%= (session.getAttribute("PetStore_Name") != null) ? session.getAttribute("PetStore_Name").toString() : " to the Java PET STORE" %>
problem:
the welcome note always displays WELCOME TO THE JAVA PET STORE, i cant get the personalise version to work.
to test i removed the redirect (from the login page so keeps posting to login) and copied the welcome note code to the login page..this worked fine ?
does the redirect invalidateto the session object....I tried your code, it works.
Check your cookies setting, are they turned off? Few servers use cookies for session maintainence but if your URLRewriting is not turned on and cookies are turned of then you won't have the same session accross multiple pages. check to see if the cookies are on, on your browser settings. -
Passing telnet session between LabVIEW calls from TestStand
From TestStand I am calling VI's from telnet.llb.
In one TestStand step am opening a telnet session to an IP address and collecting the telnet connection (U32). In the next TestStand step I pass the telnet connection to a telnet write VI but get this error.
"Dequeue Element in Acquire Semaphore.vi:1->Telnet Write.vi:1->Telnet Write.vi.ProxyCaller"
The telnet open, write, read, and close work great if I pass the telnet session number within the same VI. But I need to keep the session open between calls from TestStand because one huge VI is not feasible.
thank you
josh
Solved!

Change Password via telnet session
Hi,
I would like to know how to change the tacacs enable password via telnet session.
When a new user login the first time via telnet, tacacs prompts the user with changing login password. However, it never prompts to change the enable password. Please advice.I am not clear what your problem is. TACACS uses a single password for a user and does not distinguish an enable password which is different from the login password. TACACS will grant access to enable based on what is set up in the user profile (or group profile) not on having a separate password. The difference between a login password and the enable password is used by the router locally when the router is not able to communicate with the TACACS server.
So when TACACS prompts a new user to change the initial setup password, that is all that TACACS needs to do.

PLEASE PLEASE help!!! Telnet session echo problem
All,
I posted this question before but did not get any solutions. I am posting this again and hopefully someone can help me this time.
The implementation:
I have created a GUI based telnet session which simulates UNIX X-term window. I used the JTextArea to gather the input from user and to display the output received from the socket output pipe. I have 1 thread does nothing but listen to the socket output pipe and append whatever received to the text area, the KeyListener interface was used on JTextArea to retrieve user inputs. Every time when key is typed the getKeyChar() is sent to the socket thru the input pipe.
The problem:
As mentioned above every time the getKeyChar() is sent to the socket it will be displayed on the TextArea twice (One is user typed and one is received from the socket I guess). So, it's like when you type "ls" it will display "llss". Other than this everything else works fine.
Can someone PLEASE give me some advice?
Thank you in advance.
LeoIf you can't make the service that you're connecting to stop echoing the characters back to you (which is probably not what you want), you'll need to filter the characters received and strip out the ones you've sent.
or
There might be a way to implement a Keyboard input listener and trap the key presses preventing them from being entered into the text area which would solve your problem. The characters in the text area would be the echoed ones. -
How to disconnect a telnet session ?
Router#show use
Line User Host(s) Idle Location
98 vty 0 idle 3d22h x.x.x.x
99 vty 1 idle 3d21h x.x.x.x
100 vty 2 idle 2d11h x.x.x.y
*101 vty 3 idle 00:00:00 x.x.x.z
Hi guys, I wanna disconnect telnet sessions 98, 99, and 100. How do I do it ? Thanks in advance.Atif is quite correct that clear line is how to terminate those telnet sessions - once the problem has developed. And his suggestion that the problem be prevented by configuring an idle timeout is what I also recommend.
Looking at the idle time of these sessions certainly suggests that someone has configured the vty lines with exec-timeout 0 0 which disables the idle timeout. This has the effect that telnet sessions may go on for a very long time - and over a period of time hung telnet sessions may make all the vty ports busy and prevent remote access to the router. While I might not go as short as Atif's suggestion of a 5 minute timeout, I believe that the vty should have some timeout (perhaps quite long - especially in a testing or development environment). A vty with no idle timeout is a problem waiting to happen.

Session is not getting invalidated when i access more then 1 war applications
I am experiencing the following problem and i do not understand
the reason. I have an application (3 jsps) in a directory

Now i login in the default application that i have i link that takes me to the
second app (the war); then i go to the default
app and i logout. When i logout i invalidate the session. but it
seems that the session is not getting invalided because i can
enter the default
application and the war test application without login in.
If i do not access the test war application from the default application the session
is invalidate and i get the login page.
I hope i am clear.
Thanks
Ibrahim
I asked a similar question some time ago and the answer that I got was that each
application (war file) has its own session object. You cannot transfer information
from one application to another via the session id.

SA520 seems to terminate Telnet session
Question: We recently replaced a router with Cisco SA520. The connection is only used for a Telnet application. After replacing the router we experience the problem that the Telnet session is terminated after around one minute of inactivity in a way that it does not respond to keyboard input anymore. With out old router this happend after 30 minutes.
Everythink works fine as long as the user does actively use the system.
The SA520 is configured with a static external and internal IP address. Two ports are forwarded (515,9100) from the external side (where the Telnet server resides) to an internal printer.
Does anyone have idea what is causing this problem.
Thank you
SaschaYour timeout is probabally set very low.
TRY THIS:
Router(config)#line vty 0 4
Router(config-line)#exec-timeout 30
If you still have a problem please let us know.
NOTE:
I did the timeout for 30 minutes because that it what your old setting was. -
How can I send an F5 thru a telnet session?
I have to logon to a remote machine with a telnet session. To do this manually, I have to hit F5 to bring up the login prompt after the telnet session is established. I can establish the connection with LabVIEW, but how can I send the F5?
Telnet is essentially an ASCII-only protocol. There's no "F5" in ASCII, so you're probably supposed to send some sequence of ASCII codes to make it work.
Typically, text-based telnet programs emulate various kinds of physical terminals, such as DEC's warhorse "vt52" and "vt100" terminals, or the old ADM-3A. Those terminals sometimes had special keys that could send a sequence of commands. For example, I think the vt100 had an "F5" key that sent Escape (a byte containing decimal 27) followed by the letters "Ot". (I am looking at a UNIX box with an /etc/termcap entry for a vt100, and interpreting what it says. I'm not an expert at UNIX /etc/termcap entries, so I may be misreading it.)
Anyway, you need to find out what kind of terminal this remote machine
is expecting you to use. This will tell you what string to send for an F5 key.
I hope this helps. -
Hi,
When i login to the server which is using Solaris 9 using telnet, something is breaking telnet sessions in our machines. For workaround, we changed the IP address and it got resolved for now.
I want to revert back to the original statics IP. But i am suspecting that the same issue can occur again. Why the telnet sessions are breaking? Can anybody help me out on this issue?
ThanksThanks for the information.
Some users are able to telnet as a application user and some random users are not able to telnet and they are facing this issue.
Their telnet sessions are terminating without showing any error. If the problem is with firewall or any network equipment then it wont work for anybody, but the issue was it is not working for only some of the random users. Is there any possibility of issue with DNS?can anybody help me out on this? -
