Telnet session limit in Solaris 2.6

Got a machine here that people are trying to connect to but when the number of telnet connections reaches 15 it stops excepting them. I should really know this, but is this set anywhere and can i change it?
Thanks
Daz

I'm not familiar with "connect error 15" (is this from a solaris client?). "host closed connection" is just a state. That could be normal (when the user exits the shell), or abnormal when something else is shutting things down. You'd have to look further to see what's going on.
One step might be to run 'truss -f' on the inetd process as a connection is initiated. You can then follow the execution trail to see what is invoked. inetd should run an in.telnetd, which then runs the login shell. A comparison of what the problem machine is doing against a normal process should show vital differences.

CLI session limit 32 reached. Exiting. on nexus n5k

Hi Guys ,
I'm having a problem with Nexus n5k , when i'm trying to telnet to the machine ,i get this error :
"CLI session limit 32 reached. Exiting."
I can connect to it by console ,but i don;t know how to clear all those sessions .
Needs help
Thanks ,
Ron

I am also having this issue on out 5Ks. We resolved the problem before by consoling into the system and doing "show users" and then "clear line (vty-line)". This will allow you to ssh or telnet into the system again. But I am wondering how I can determine why this is happening all of a sudden. I have been working with our Nexus 5K for over a year and a half and have never had this issue. Now all of a sudden it has happend two time in the last 3 months. What do I need to look into to resolve this? I am not not exiting properly and it is not killing the session? Please advise.

Setting the 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.

in vi editor you must insert 2 line feed characters and then a cariage return.
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>

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.

Configure the maximum session limit of sshd

I have a need to increase the limit of the number of concurrent ssh sessions to a Solaris system. I have found the system's sshd_config file and I see '#MaxStartups 10'. Does this control the limit?
Thanks,

     MaxStartups
             Specifies the maximum number of concurrent unauthenticated con-
             nections to the SSH daemon. Additional connections will be
             dropped until authentication succeeds or the LoginGraceTime
             expires for a connection. The default is 10.
[...]So it doesn't affect total completed connections.

Telnet session terminating

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?
Thanks

Thanks 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?

Is there any session limit in operator?

Hi,
I am trying to run a loop thru a query, like " select col1 from table1", then in this loop I am trying to call a scenario, like : OdiStartScen -SCEN_NAME=TESTEXTRACT -LOG_LEVEL=5 -SYNC_MODE=1 "-project.var1=#col" , the query should return about 7000 rows, that means the scenario should run for about 7000 times, but the fact is in operator is only run about 60 times, and no new session produced, and the main loop is hanging there?
Is there any session limit for the operator? or any other possible resovle method for this?
Thanks

Hi ,
You can limit the number of session u can view in the Operator.
In Operator--- > File --- > User parameters = In this you can see operator display limit. In tat you can set ....
Hope this helps !

How do I establish a telnet session with unit under test?

I am going to the next step as a novice and moving from serial communications to ethernet on my unit under test. I have been all over the help and discussion forums etc and cannot find an answer. I need to open up a telnet session with my unit under test and keep it open to send commands back and forth for control of the unit. Can anyone give me a hint of how I am to establish this communication? I have the IP address and I am using port 23 but I just get the session started and then immediately closed. The sequence of events will be: start the session, the unit will reply with a username and then password, after that I need the session to remain open so I can send commands as if I am sitting at the serial port. When complete the session will then be terminated. Thanks in advance for any help.

If you want to do telnet using plain TCP, you need to do everything yourself, including the telnet options negotiation.
RFC 854 should have most of what you need (look towards the bottom).
Most likely, the server will propose a few options, which you should either accept or reject depending on your needs.
Easiest is probably to use a packet sniffer on a regular telnet session, then dissect the negotiation to see what that particular server wants.
RFC 990 has a list of telnet options, look for the section labeled "ASSIGNED TELNET OPTIONS".
It should be simple to write some code that negotiates with one particular host. It will be more difficult to write a full-blown telnet client that does general negotiations with any type of telnet server.
I have a small program that telnets to a router to do some configuration. The only thing I reply to the proposed options is:
"\FF\FD\03\FF\FE\01\r\n" (In \-codes). Translated: "Don't suppress go ahead, Do echo".
(FF=IAC "Interpret as command", FD=Do, FE=Don't, 01=echo, 03= suppress go ahead.)

Placing a telnet session within a java swing program

I was wondering if there was a way to maybe anchor a telnet session into a JPanel within a Java Swing program. Most of my users end up running a telnet session while using my Swing Program and I was hoping to find a way to bring the two together. If this is possible could someone point me in the right direction (like an online resource) that might show me how to do this.

You could use sockets and a TextArea and build your own simple telnet application.

Run 6i form in a telnet session on a 32 bit Windows environment

Hi,
We have the following environment: 8.1.7 database, 9iDS Forms 6i (6.0.8.13.0) included. This is installed on 32 bit windows environment. We have wireless RF barcode scanners with TCP/IP connection. So they can connect to Unix box or a Windows telnet session. As we have Windows system we can connect this equipments to Windows through telnet session.
I heard and read in some topics that Forms 6i can run in character mode environment. But I didn't find any solution.
We would like to run forms as we can run svrmgrl for example on a telnet session.
My question is that it is possible to run 6i forms on charcater mode environment (telnet session) ? If so, what we need to do in the development or running phase (command line parameters for example).
Thanks in advance,
Attila

Forms 6i can run in Character mode in telnet - but this only applies to Unix ports of the product - they have an f60run executable as well as the Gui f60runm and the Web f60runw runtimes.
Windows only has GUI and Web versions.

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

Exceeded session limit on CPU usage

Hi All,
We are getting message while generating some reports. Pl. see the Error Text below for message. For time being we have bumped the session limit to unlimited to take care of this problem for now. But the question is u201CIs there a way available in MII to refresh(cycle) the Data source connectionu201D So that the DB session limit can be kept un altered?
When we search this on different forums, we got a solution which we aleady implemented(bumping the session limit to unlimited). But we are looking for a solution from MII side.
Any help will be appreciated
Regards,
Rajesh.

Hi,
Kindly try out the below option from database side.
Error : ORA-02392: exceeded session limit on CPU usage, you are being logged off
Cause : An attempt was made to exceed the maximum CPU usage allowed by the CPU_PER_SESSION clause of the user profile.
Action : If this happens often, ask the database administrator to increase the CPU_PER_SESSION limit of the user profile.
If you looking for solution in MII end,
Check with SAP MII administrator on log files.
Check Data server tab for configuration details. (eg : Pool Size, Pool Max etc)
Kindly let us know the version of SAP MII.
Thanks
Rajesh Sivaprakasam.

Oracle 8.1.7.4 is the final patchset of the last release for Oracle 8i, so it's a rather

Java sniffer for a TELNET session

Hi
I need to interpret test results of a telnet session using a java sniffer..........how do I do this.
Thx
Frederd

I need to interpret test results of a telnet session
using a java sniffer..........how do I do this.You'll need to use two computers to do this, since Telnet uses a "well known port" to accept connections (look at www.iana.org for port number). Since only one process can hold a port, you'll need to run your telnetd on one machine, and have clients connect to another where your sniffer owns that port.
Once you've set this up, the sniffer itself is a simple pass-through portal: it accepts a request, makes a corresponding connection to the actual telnetd, then simply passes bytes from one connection to the other (logging them in the middle).
