SSH sessions over Putty die unexpectedly & commandline entry is slow

I have a Sun Ultra-60 running Solaris 9 at patch level 118558-05. Users of this server report that their ssh sessions over Putty to this server die unexpectedly anywhere from one to two times per week. The users are usually in a vim session at the time editing php files for the website hosted on the system. Another problem reported is that the user's command line input slows dramatically and they must wait for the server to complete the line they were typing prior to proceeding.
I cannot find the source of this problem. To date, the following is what I have tried in my troubleshooting efforts.
1) ptdiag - reports no hardware failures
2) /var/adm/messages - reports no issues relating to the problem mentioned above.
3) swap -l - the server has plenty of swap and shows no need for additional swap space Here is the output from swap -l
swapfile dev swaplo blocks free
/dev/vx/dsk/swapvol 213,6 16 8389632 8358176
I should also mention that /tmp is not full and is currently only at 2% of it's capacity.
4) ndd shows that the link speed, duplex, etc. are correct at 100Mbps full-duplex.
5) System uptime is at 337 days and the uptime command currently shows the following load: load average: 0.12, 0.11, 0.09
6) vxdisk list shows the two internal mirrored disks as being online and no errors. iostat -En shows no soft or hard errors on the two disks
7) This server only has two users and the main applications in use are mysql and apache.
8) I have upgraded to the latest version of the vim editor and the problem still persists. I have also had the users upgrade to the latest version of Putty and to turn on the logging feature of Putty which hasn't revealed any information as to why the sessions are unexpectedly terminating.
9) I have checked the /etc/default/login setting for the "TIMEOUT" variable which is commented out. I also checked the users profiles and verified that there are no timeout variables defined.
10) Here is my netstat -i output:
Name Mtu Net/Dest Address Ipkts Ierrs Opkts Oerrs Collis Queue
lo0 8232 loopback localhost 52375982 0 52375982 0 0 0
qfe0 1500 servername servername 2319804623 29884 1493848177 0 0 0
qfe1 1500 servernamea servernamea 231550668 0 3694 0 0 0
qfe2 1500 servernameb servernameb 40944152 1 65630146 0 0 0
Some of these numbers look high, but I don't see any collisions.
Any help would be appreciated. If additional commands need to be run, please advise and I will gladly post.
Thanks much for any assistance.

Hi Darren,
The user's vim session dies when the users are actively typing.
As for there being a firewall or NAT device between the workstation and the server, yes, there is. The users are in one building and the server is housed in a datacenter in a separate building. The users do not have this issue with out other Solaris 8 and Solaris 10 servers...only this one particular server. A traceroute to the server takes only 5 hops and returns quickly.
As for the logs, I just checked /var/adm/messages and it is reporting the following types of messages over and over.:
[ID 317013 daemon.notice] bpcd[11746] from some IP
I think these messages are generated from Veritas Netbackup which is administered by a separate team than what I am on, but I can have them investigate.

and the command i'm using to ssh in
ssh -X -p 22 user@hostip
i can log in fine every time, but when i do
startx
the openbox session starts on the remote machine, when obviously i want to view it on the client. i should also add i'm using urxvt to ssh in. also, please be aware this is a very basic setup as i'm just starting with ssh.
thanks

If this is the case, why not use a tool that was designed specifically for this purpose? You could set up vnc and then forward the ports to run over ssh. But I have been playing with x2go, which is a open-source NoMachine alternative. It is super easy to set up and runs over ssh. What is really cool is that it actually runs far better than plain ol' vnc with a super responsive desktop.
I don't really have much practical use for it, but after playing with vnc a bit and seeing the shitty performance that it can sometimes have, I heard about NoMachine and decided to give it a whirl. I think the best part is that because it runs over ssh, it is as secure as your sshd setup is. So if you want to open it up to face the greater internet, as long as you feel confident in doing that with ssh, there is no additional ports you need to open up or anything.

'The process for the mtp protocol died unexpectedly'

As you can read from the title, I have problem to mount Android device in KDE. I have installed kio-mtp, and maybe it is working out of the box for other android phones out there except for mine (HTC One X).
The device mounted, but when I try to transfer files (copy, paste, cut), it throwing up an error which is 'The process for the mtp protocol died unexpectedly'.
Can somebody tell me if I'm missing something? Did I have to install any other tools to get the job done?

I'm having a similar (maybe the same) problem. I have an International Samsung Galaxy S3 (i9300). Same symptons on both stock ROM and Cyanogenmod 10.1
Try debugging the kio-slave:
Run
kdebugdialog --fullmode
and verify that kio (ID 7000) has all its outputs set to Shell. (should be the default)
Then run
kdeinit4
in a terminal and leave that terminal open. The debug messages will be displayed in that terminal.
Open dolphin and try to create a folder/copy a file/etc. on your phone and watch the debug output.
Mine is:
Device 0 (VID=04e8 and PID=685c) is a Samsung Galaxy models (MTP+ADB).

During Table Import got error ORA-12805: parallel query server died unexpectedly

Hi,
I tried to import a single table of size 51 GB which normally imported in 5 hours but last time I got following error after 1.5 hours
ORA-31693: Table data object "SCHEMA"."TABLE_NAME" failed to load/unload and is being skipped due to error:
ORA-12805: parallel query server died unexpectedly.
From the "Alert log" file I found the error is
ORA-00603: ORACLE server session terminated by fatal error
ORA-24557: error 1114 encountered while handling error 1114; exiting server process
ORA-01114: IO error writing block to file 622 (block # 373725)
ORA-27063: number of bytes read/written is incorrect
IBM AIX RISC System/6000 Error: 28: No space left on device
Additional information: -1
Additional information: 253952
I checked all the table spaces have more then 100GB free space. No idea why this happened.
Some mount points of the machine is 100% in used where the table spaces created but in table spaces auto extend is off on every data file and each data file have free space.
Anyone have idea how to resolve this issue.

Hi,
Which filesystem is file 622 in - it's quite a lrge numbered file - is it a tempfile or do you really have that many datafiles?

Apply causes ORA-12805: parallel query server died unexpectedly

Hi myora9i,
I saw similar report in MetaLink. (Bugid:3658975)
It was 9.2.0.5 on Solaris.
Unfortunately, this problem has left unsolved for 2 years due to luck of information to analyze the situation.
I couldn't get a detail of problem, but the document says "Apply process abort".
And error messages are same to yours. So I think your problem is related to the bug.
Just FYI

SSH session manager

Is there any gui tool to manage SSH sessions connection settings like for examle Putty does it?
P.S. I already know that there is putty on linux but maybe there are other alternatives?
Thanks

SSH Session Disconnecting

Hello Everybody,
I am becoming increasingly frustrated with an issue that I've seen span MANY different devices (both routers and switches, with varying IOSes installed).
The problem I am seeing is when I am scrolling through the logs on a router or switch (by holding the spacebar), my session will disconnect. This happens using SSH in both PuTTY and SecureCRT.
I have seen this same issue occur when performing a show tech, as well as when holding spacebar while scrolling through a show int status on some of our Nexus switches with many, many ports configured.
I have checked the available resources after signing back in, and each time available resources have been sufficient. Has anyone else experienced this issue or perhaps know of a cause/resolution?
Thanks!

Hello Jason! Sorry to hear about the problem. This sort of issue needs a TAC case, because there is clearly a software bug. What platform and software version are you using?
CSCsd98525 describes a similar issue, limited only to IOS. CSCsz83570 also describes a similar issue.
A workaround is to force the use of SSHv1 until you apply the software fix.
Also, at least for CSCsz83570, setting "term len 0" tends to prevent the disconnect, as does switching to 3DES instead of AES. This bug is triggered by TCP congestion and those two workarounds avod the issue. Swicthing to SSHv1 does as well.

HT1349 How do I de authorise a computer that died unexpectedly.

How do I de authorise a computer that died unexpectedly?

You actually have to use the computer itself in order to deauthorize that computer - if that is the only computer that you want to deauthorize - or you can deauthorize all computers - and then authorize them all over again. Read this for more info.
http://support.apple.com/kb/HT1420
I had an iMac die on me about two years ago and was not able to deauthorize it for the reason explained above. I did not want to deauthorize and then authorize my other 3 computers, so I plan on not worrying about it until I reach the 5 computer limit. That is my advice to you as well - if you have not yet reached the limit - don't worry about it.

Screen Sharing and SSH sessions freeze occasionally on multiple mac minis

I have 28 Mac Minis at work. With such a large number of minis, I obviously can't have a monitor attached to each of them so I've got them plugged into a network switch and access them via Screen Sharing (both via regular Screen Sharing and ARD) and SSH sessions.
A few of them seem to suffer from intermittent problems however. I'll be using Screen Sharing when the session freezes. It may unfreeze eventually, but I can also usually just quit out and re-connect and it will be unfrozen. The same thing happens when I'm connected via SSH, it will freeze and I won't be able to type in any more commands.
I need help troubleshooting (or if anyone knows what could be causing this, that'd be cool too).
I've tried connecting from both a Mac Pro on the wired network and a MacBook Pro on the wireless network. The freezing seems to only happen on certain Mac Minis as well.
I've tried switching network cables from a Mac Mini that doesn't suffer from this problem with one that does and nothing changed.
I also thought it might be a bandwidth issue at first, despite being a gigabit switch connected via cat6 to the rest of our gigabit network, but even when no significant bandwidth is being used, the freezing still occurs.
One more thing I want to test is the connection between the switch all these Mac Minis is plugged into and one of the other switches that all our other network traffic goes through. I didn't set it up myself so I fear that it might be an old, damaged cable or something. Failing that, I have no idea what the problem could be, which is why I'm posting here.
So, does anyone have any idea what the problem could be? Or any other ideas for troubleshooting the problem? Thanks.
(They're all running 10.6.8, and range from Mid-2007 to 2009 models).

It would be in the system log. However, the next step would be to safe-boot in order to eliminate third-party system modifications. That goes for both client and server. If you can reproduce the problem in safe mode, then you probably have a network issue. Take everything offline except one client and one server, and test.

ACE 4710. Unable to clear ssh sessions

Hi.
Once in the CLI of an ACE 4710, using the command "clear ssh session id" I am unable to clear/kill any of the remote ssh sessions established.
According to the administration guide, the "clear ssh .." command must clear the sessions, but it does not, or maybe I am missing something?

I hade some tries with /usr/bin/script -a <somewhere> in the .bash_profile but this is not what i need. e.g. "exit" exits the script and not the session.
do you have some clever idea how to solve the issue?
i can�t find any helpful tool.
chears, claudius

No, i have a System where some users get the possibility to access the server by ssh. To have a control, what the user did - and do have a verification when he did something wrong - i would like to have a possibility to see what he did within the session (e.g. editing a configfile) I had some tries with "script" and other little OS-tools but, i was�nt able to find a perfect sollution.
Perfect meens - it�works and it is not vissible for the user.

How to reconnect to a disconnected remote ssh session on solaris 10

hi all
How to reconnect to a disconnected remote ssh session on solaris 10
is there a way to accomplish this

No, there's not.
A common solution for this is to get a copy of 'screen'. After connecting via ssh (or any other protocol), you can start a "screen" session. If you get disconnected (or disconnect intentionally), you can later come back on the machine and bring your existing "screen" session back.

Problem establishing SNA session over DLSw link

We are experiencing sporadic problems establishing an SNA session over a DLSw tunnel. The session is between a Tandem host and a CICS region on OS/390. A Cisco 7500 router performs one end of the DLSw link; that same router is channel-attached to the OS/390 mainframe using CIP and uses CSNA for SNA traffic.
The connection is initiated by the SNA software on the Tandem box, but it rarely works on the first attempt. The session goes into a pending state and has to be cancelled and re-tried. This has to be repeated until such time it is successful. Once the session is started it works without problem.
At the point of attempting to start the session all the components are in the 'correct' state, i.e.
-DLSw tunnel is connected
-Host PU is in 'connectable' (CONCT) state
-Host XCA defining CIP SNA and virtual lines are active
No action needs to be taken on the OS/390 end of the link (or anywhere else for that matter) between start attempts on Tandem.
From device traces on OS/390 my suspicion is that the session requests are not actually getting to VTAM on OS/390 for some reason. DLSw traces on 7500 appear the same in both case of success or fail of session start.
Has anyone experienced this, or know of problems in this area that may explain what we are seeing?
Thanks.
Keith

Mary,
thanks for the extra information.
I would advice at this point the following:
Open a case with the Tac. Provide the information you have at that point and agree on a action plan, i.e. what to look at what trace to take, when you are able to recreate the problem.
What i can see from the documents you attaches is the following:
I only see sna circuits in the dlsw circuit history.
In you show dlsw reach there are quite some netbios names aswell and a large number of mac addresses learned from the remote peer.
You may want to discuss some filter options with the tac to make sure we cut down on the size of the reach cache and to make sure we advertise only those mac addresses which are really needed.
From the show version, 12.1(17) should be fine for dlsw in the way you described it.
From the show dlsw circuit history detail we have a couple of times that circuits are disconnecting.
Most of the time these circuits are up for a long time and they get the following sequence before terminating:

CLOSE_PEND DLC CloseStnCnf 0x0 DISCONNECTED
this circuit was up for more than a month and the reason for disconnection was ADM WAN failure which means the dlsw peer went away at some point.
Some other circuits get these sequence:
CONNECTED WAN infoframe 0x0 CONNECTED
CONNECTED WAN halt-dl 0x0 HALT_PENDING
WAN halt-dl means the other end tells us to disconnect. No information on this end why. Most of the time it is a legitimate disconnect. but you would need to look at the dlsw peer to get information who terminated the session.
I dont see anything specific in a sense that a circuit did not go to connect at all. In the information you supplied.
Again my advice open a case with the tac and then you can work the issue to completion.
thanks...

After crashing, Firefox is not re-openeing saved tabs from my last session, but is re-opening tabs from a session over a month old. How do I find my saved tabs?

This can be a problem with the file [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
Delete [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
