Terminal sessions dropped

A customer has the following conf.
Two sites connected with a VPN through internet .
On site A there's a Win2k Server with terminal services. Users on Site B connect via RDP but after 10minutes ( even working ) the session is disconnected.
Between the two sites a tunnel has also been defined to manage a ISDN dialup backup line .
Anyone has any idea ?
thanks

try scaling down the mtu size on the client
use the VPN client > Set MTU option
or do it in the registry
if you can still browse web pages on the internal network even after the TermServer has kicked you off, then the mtu may be the culprit. try setting it to a lower value. Also try setting the RDP Properties for the connection down to 56K (play with these settings first, they may make the difference). Terminal Sessions use bigger packets than HTTP Request and Response traffic.

KB2923545 remote sessions drop issue

In our environment we have Remote Desktop Services Host running patched and up to date Windows 2008 R2 Enterprise behind Remote Desktop Gateway running Windows 2012 R2 Standard. Dual Factor
Authentication from Windows Azure is used in our system as well.<o:p></o:p>
We experienced following strange behavior. Users with updated Windows 7 clients can successfully authenticate against RD Gateway, receive a call from Windows Azure DFA, authenticate
and establish remote session to RDSH. No issues while working in remote session until user need step back or minimize the active RD session window. After 120 seconds the session get dropped and reconnects immediately and the user receives another authentication
call from DFA.<o:p></o:p>
No errors on client side, no errors on DFA, RDG or RDSH servers, just entries that the session was disconnected and then reconnected.<o:p></o:p>
Running Wireshark on the clients side shows that the local computer sends RST, ACK which drops connection and then immediately sends SYN to RDG server with initiates connection reestablishment
and a call from DFA. <o:p></o:p>
We figured out that this behavior is related to the stations with KB2923545 installed. As soon as we remove mentioned KB, no session drops.<o:p></o:p>
Anybody experiencing the same and had found other solution then just removing windows update KB2923545? <o:p></o:p>

Hi,
Thank you for posting in Windows Server Forum.
Does this happen on any particular system with specific account?
As this KB is specific for the issue for your issue, here suggest you to install on another system or reinstall the KB after restating the system. And finally check with new user account without any permission.
Hope it helps!
Thanks.

Windows terminal sessions not logging off

Hi All,
I am new to SDG and hoping someone could shed some light on a issue i'm having with applications running on a windows terminal server.
When i launch a windows application through SGD, it opens and works fine. When I close this application and session, it seems that the terminal session is still being held. Why does it not log off? Is there a SDG setting?
Any help would be appreciated.
Jason

It looks like a process/application running in the background is keeping the session open.
Please take a look at the following section from the administration guide:

Terminated session

how can i terminated session?
doesn't state in v$session with status killed.
Edited by: Shahin Karimov on Aug 4, 2009 2:43 AM

Hi
Step 1
SELECT s.sid,
s.serial#,
s.osuser,
s.program
FROM v$session s;
SID SERIAL# OSUSER PROGRAM
*1 1 SYSTEM ORACLE.EXE*
*2 1 SYSTEM ORACLE.EXE*
*3 1 SYSTEM ORACLE.EXE*
*4 1 SYSTEM ORACLE.EXE*
*5 1 SYSTEM ORACLE.EXE*
*6 1 SYSTEM ORACLE.EXE*
*20 60 SYSTEM DBSNMP.EXE*
*43 11215 USER1 SQLPLUSW.EXE*
*33 5337 USER2 SQLPLUSW.EXE*
Step 2
SQL> ALTER SYSTEM KILL SESSION 'sid,serial#';
In some situations the Oracle.exe is not able to kill the session immediately. In these cases the session will be "marked for kill". It will then be killed as soon as possible.
Issuing the ALTER SYSTEM KILL SESSION command is the only safe way to kill an Oracle session. If the marked session persists for some time you may consider killing the process at the operating system level, as explained below. Killing OS processes is dangerous and can lead to instance failures, so do this at your own peril.
It is possible to force the kill by adding the IMMEDIATE keyword:
SQL> ALTER SYSTEM KILL SESSION 'sid,serial#' IMMEDIATE;

Can't format disk in a terminal session

Hi,
I'm trying to reinstall my mac os x server software on my headless xserve. It has a PCI raid card in and I have created a 500gb logical raid 5 volume (megaraid -create auto). However when I boot the xserve from the setup disk and then use server assist on another mac on the network to install the system it does not see any volumes available to intall the software. I know I need to format the drive but every diskutil command I try just seems to hang the terminal session and nothing happens. Please could someone give me an idea as to the terminal commands I need to use to make the volume visable to server assist.
Thanks in advance for your help

Hi CKlitho,
   The UNIX command, diskutil, will do anything that the GUI app, Disk Utility, will so it doesn't matter whether you use the command line or not. If there is a device file for the drive, then it is attached, can be mounted and you can do anything you want with it. Otherwise, it might as well not even be connected to the computer. You may be able to tell if there's a device file with the "df" command. (no parentheses or arguments required)
   I'm guessing that there is no device file, since otherwise the disk would probably be visible to Disk Utility. If that's the case then the problem is probably that there's no driver for the PCI card on the setup disk. If that's so you will have to arrange to boot from something that contains the driver in order to do what you want.

GC most appropriate for 200 MS Terminal Sessions running large Applet

We are load testing a J2EE application using a tool called App Loader. The client for this J2EE application is a large applet which runs from 60 mb of jars. We are running the applet in IE 6 on W2k3 X64 Enterprise in each of 200 Terminal Sessions on a 16 Core 2.4 Ghz server with 128Gb RAM. We have the following JVM parameters for the clients -Xrs -Xms128m -Xmx128m -XX\:+DisableExplicitGC.
We are experiencing what appears to be missed mouse clicks on various gui objects that rmi to server. This occurs during a one hour run to approximately 20% of our clients. These clients eventually timeout after 120 seconds and die in the App Loader tool. We have seen some improvement in failure rates by coding +DisableExplicitGC.which suppressed a Full GC every 60 seconds apparently explicitly called by RMI.
The GC logs appear to show the serial collector:
0.450: [GC 0.451: [DefNew: 8128K->960K(9088K), 0.0139519 secs] 8128K->1424K(130112K), 0.0140565 secs]

The question: Is there a better GC to use for this strange environment of Terminal Services and Applets where we have 200 JVMs running concurrently and each JVM is doing individual GC,

After terminated the blocking session using kill with SID and SERIAL#
the system was running normal, now i like to go back and try to figure out
what the blocking session was doing at that time.
Please advise how to trace a terminated session.
Thanks for your assistance.

Terminal Session Not Supported

Hi ,
I have bought a new macbook pro and use Juniper VPN to connect to my work machine (Windows). Below are the steps I perform to connect to my terminal session
1) Login to the VPN url. for example - https://secure.mycompany.com/
2) Enter the UserID and Password
3) Connect to the Terminal sessions configured.
Now, When I try to launch the terminal session, I recieve an error message saying "This terminal session is not supported on your computer".
Any help on resolving this issue is highly appreciated.
Thanks,
Trish

Hey,
I am in the same boat.
Did you manage to find any solution? My Work IT team has got no clue about this.

BGP Session drops when loading routes into a VRF

I've configured a small MPLS network with 4 P routers (ASR 1002s) 4 PE routers (6509s) and two Cisco 7206s as route reflectors. I'm using OSPF as the routing protocol on the PE-CE interfaces and have sham links configured between PE routers. I currently have two VRFs configured on this network, one is working fine, and there are approximately 150 routes in this VRF.
The second vrf is configured, it also has ospf sham links configured, neighbors up, etc.
The problem I have is that when I bring up the first PE-CE link and load about 7000 routes into the second vrf my BGP sessions between the other PEs and route-reflectors start timing out. I do show the vpnv4 routes show up in the route-reflectors "sh ip bgp vpnv4 rd 14017:2" I believe the debug outputs below indicate the issue is in the route-reflectors, but was curious if anyone else had seen this issue. The BGP peering IP address for one of the route-reflectors is 10.2.0.7 and one of the session dropping PEs is 10.2.0.13.
Normal output from "unloaded" debug ip bgp vpnv4 unicast keepalives:

did you check this?

I honestly do not remember the defaults in Cisco but I had a very similar issue working with Juniper because of this value was set @ about 4500 prefixes at once.

Shell script to launch terminal session with environment sourced

Hi all
I've installed 12.1.1 on OEL 5.
As i've installed with a single user, I will need to switch between the app and db tier.
I'd like to create two scripts, one that opens a terminal session and sources the app env file, and another one that opens the terminal session and sources the db env file.
Anyone done anything like this before?
Thanks

Terminal session not supported by your computer

I can login to my work environment but when I try and initiate a remote session link to my work computer, I get an error message that says "This terminal session is not supported by your computer."
I need to be able to log in and remotely access my PC at work. Any suggestions are appreciated.....

what OS on your work computer? What is already installed on it to allow remote control? Is that software enabled?
If remote os is MacOs - Apple Remote Desktop is actually server component, I mean it is not included in desktop MacOs of your home mac. But search can help.
If remote os is Win - you need this: http://www.microsoft.com/mac/remote-desktop-client on home mac
and in both cases - proper configuration.
anyway you need properly configured tunneling thru workplace firewall, so some assistance from admin.

Session drop trough OleDb

Hi guys!
I have a major problem. I use an Oracle 8.1.6 server and I connect my client to the server trough OleDb (v8.1.6).
After some time when my connection is idle the server drops
the session. It's strange, because it doesn't drop me out if I'm logged in trough SQL-Plus. I'm suspicious that's because of OleDb. My question is: is there any parameter in OleDb for setting this idle time session drop thing? Any methods, functions, etc...
Hint: I see all the resources UNLIMITED in my dba_profiles.
Thank for helping me
Viktor Havasi

Hi
We had exactly the same problem and got it solved doing the following:
Check your regitry for the key SPTimeout in
HKEY_CLASSES_ROOT\CLSID\{3F63C36E-51A3-11D2-BB7D-00C04FA30080}
We foung this was missing. just inserted SPTimeout = 60 (default value is 60 sec) and oops the session is not dropping!!

Where are logs from old Terminal sessions stored?

Is there a way to look at logs from previous Terminal sessions?

Ahh, you don't need to know where the file is, then. Just press the "up" key repeatedly in the Terminal to scroll through previous commands.
If it has been a while, press control-R and start typing what you think the start of the command is.
If that doesn't work, execute this command in the Terminal:
cp ~/.bash_history ~/Desktop/bash_history.txt
Then open the copy of the history file, created on your desktop, in the text editor of your choice and browse.

Terminal Server Session Management: why do we need a rdp session to take control of a terminal session?

Hi all,
As title, I have this question: why do we need a rdp session to take remote control of a terminal server session?
I copied tsadmin and related file to a windows 8.1 pc and I'm able to see for every terminal server the list of users logged in, but the option "take control" is greyed out... why? is not possible to avoid this block?
Thanks in advance
Davide

Hello, Davide_ita.
Also tried to use RDSM to "Remote Control" user's sessions, but in this thread
Remote Control
with Remote Desktop Services Manager - error Access is denied (Windows Server 2012 R2)
I get the recommendation to use RDP or Remote Assistance.
The quote of
TP []:
Hi,
You cannot remote control a session on a 2012 R2 RDSH server using Remote Desktop Services Manager. You need to use the RDP 8.1 mstsc.exe or the RDS gui in Server Manager on 2012 R2. The command you would use with the RDP 8.1 client would be
this:
mstsc /shadow:<sessionid> /control

Iscsi session dropped

Hi people,
OS: Oracle Enterprise Linux 4.5
Storage Server: Openfiler 2.3
I have been trying to setup an Oracle Cluster using Openfiler 2.3 and Oracle Enterprise Linux 4.5. Wen I try to boot up both of my nodes in a cluster, the nodes will find the targets and immediately drop the session, thus shutting down both of my NIC (eth0 and eth1). I have googled till my eyes popped out, below is the error I'm facing:
iscsi-sfnet:host3: Connect failed with rc -113: No route to host
iscsi-sfnet:host3: establish_session failed. Could not connect to target
iscsi-sfnet:host3: Waiting 1 seconds before next login attempt
Has anyone ever came across this error?
Please note that I have tried the solutions mentioned in the below links:
http://www.cuddletech.com/blog/pivot/entry.php?id=601
http://www.nabble.com/Login-Timeout-errors-td5389892.html
Any help will be highly appreciated.
Regards,
Durbanite - South Africa

Hi Tommy,
Apologies for the late reply, I will try your suggestion. I will need to turn off the linux server completely as you can't open another session, as soon as this error occur, it shuts down your NICs and from there you cant telnet/ssh or open any session. Even if you try to login locally, the error messages will keep on flashing on your screen.
Thanks for your help. I'll get back to you.
