Can no longer connect via serial port

Hi all,
I am an administrator for forty-eight Solaris servers scattered around the world, I have remote console connectivty via Cisco 2821 terminal servers. Recently all the devices were moved to new terminal servers but I can no longer get remote console connectivity to fourteen of them. Most of the servers just give a blank line. I have had the port and cable changed on two of them with no joy. One of the servers was local so I risked a reboot (didn't fancy rebooting one of the distant ones as hands-and-eyes support staff are difficult to get hold of and these are production boxes.). While connected via IP I attempted a reboot, after 20minutes of waiting I decided I'd have to connect directly with my laptop, when I connected the machine was waiting for an ilom login. After logging in and completing the boot the server was working fine and I could connect via the terminal server.
The boxes are Sun 5220's and I am running Solaris 10.
Any help would be greatfully received as I really don't fancy trying to reboot the other thirteen boxes with nobody onsite...
Cheers,
Mark T.

Answered my own question:
opened another terminal window and used the command killall ssh to abort the previous session.
Still don't know why it won't login to my server.

Process Name when we connect via Serial Port ,Its URGENT !!!

Hi,
I am working with Sun Solaris 9 sparc and in my application,I have to communicate with the serial port.
For every connection we made, in Solaris it creates a process.So Can anyone tell me the name of the process when we connect serial cable??
like USB connection /dev/usb0 or /dev/hiddev0 process is created..
Thanks in Adavnce ...

For every connection we made, in Solaris it creates a process.Are you talking about 'telnet' or 'ssh'? Those work differently from serial connections.
So Can anyone tell me the name of the process when we connect serial cable??You might have a login listener if you configure it, otherwise, nothing is running.
You need to provide more details about how you intend to use the serial cable. I can't tell from your post.

TS2756 I can no longer connect via USB/service missing

..& my iPhone does not show up on the list anymore. I can still use Wi-Fi, though. I would like to be able to use the USB connection again. Resetting the network settings doesn't help. BTW, I'm using it with my MacBook Pro running 10.7.5 and my iPhone has the latest iOS update as well.
When I first got the phone, I always used my internet connection via USB, but then it started giving me trouble. I tried all kinds of suggestions that I found here and it was a real crap shoot -- sometimes it worked, and sometimes not. Now it just won't work at all. I recently deleted my iPhone from the list of services thinking that the next time I plugged it in, it would recreated the service. It did not. So, I'm still using it as before: just connecting over Wi-Fi (the network is still available, it just doesn't show up in my list of services on the left-hand column under "network").
Anyone have any suggestions that they know will fix this?

Hi DaveX83 and welcome to the discussions.
A few things to try.
Press the reset button once on the back of your Extreme and let it restart. Check for proper operation.
If no help there, keep the ethernet cable connected, and open Airport Utility. Click on Manual Setup near the bottom of the pane. On the next screen click the Airport icon at the upper left of the pane, then click Wireless in the line just below that reads Summary - Time Capsule - Wireless - Access.
Check to see that your wireless is set up, security set up, passwords, etc. You may need to reconfigure your wireless settings again and update the Extreme to store them and restart.
Hope this helps.

ConnectionNotFoundException when connecting via serial port

Hi all
I have got a HttpConnection that looks like this
HttpConnection connection = (HttpConnection)Connector.open( "http://localhost:80/test/read.txt" );
InputStream inputstream = connection.openInputStream();
...The above codes work fine on the emulator, but when I wish to connect to the server via the device from the usb cable, it throws me an javax.microedition.io.ConnectionNotFoundException
I'm working on a SE W880i and is running the midlet from the Device Explorer...

Hi,
thanks for the response.
no, I can't login to the switch(es) at all. There seems to be no response from hyperterminal at all. (Then I noticed that the LEDs had gone "solid" and that everyone started to complain they had lost network connection!)
Even when I powered off and powered on the switch with the console port still connected, nothing appeared on the hyperterminal screen.
However, as mentioned, I'm able to connect to one of our spare switches using the same settings, same laptop, and same console cable - so I guess that would rule these things out as being the cause?
Its definitely a strange one, especially as it seems to be affecting all 3 of the live switches!

Eurotherm 2704 connection via serial port with ModBus

Hello guys,
first some words about my problem:
I have to develop a software which allows reading and writing the
temperature (we have 3 Eurotherm 2704) (I think some of you know this problem yet ).
I wrote already the program and it works, but I used "iTools OPC
Server" for my program and it was the demo version (works only 30 minutes).
The group doesn't want to pay for the iTools, I should solve this problem without
iTools .
In this forum I found out, that I can use the ModBus for it:
http://forums.ni.com/ni/board/message?board.id=170&thread.id=468139&view=by_date_ascending&page=2
I know, there are some similar threads here, but I am new with LabView
and need some help.
I downloaded one example “my modbus serial query.vi “
http://forums.ni.com/ni/board/message?board.id=170&thread.id=135288&view=by_date_ascending&page=2
but it does not work (I am not really sure, what I have to change in the
file)
With OPC Server I found out:
COM5
Baud Rate 9600
Parity: None
Flow Control: None
Data Bits: 8(RTU) (I can choose RTU, but where can I change to 8 bit ?! )
And by other properties, I have no idea what I have to change there
For Example
Modbus Data Unit In (all read and write mode ? Which one do I need to read the temperature and to set the set temperature?)
Modbus Command ?!!!
No idea.
I have folowing adresses (comms address 0x00030001, canonical address: 1)
Which one do I need ?!
I think if I get the signal from one temperature controller, I can do it for
other, but my problem is now THIS one.
Can you help me whit it ?
Should I use a other example ?! Maybe do you know better one?
Thank you, very much.
Alexander

Hello Putnam and Christian,
I think the problem because you can not understand my question is my English, sorry
I'll try it again:
@Christian:
Thank you for the links, but I think all threads in NI Forum with topic "Help, Eurotherm 2704 ?" were written by me
You understood my problem correctly.
We have 3 temperature controllers and I have to develop a LabView program, which allows reading the temperature from the controllers. It should be possible to write the set temperature from LabView to temperature controller as well.
The controllers are connected already (I think with RS485) and I can read/set the data from/to controllers (with “iTools OPC Server”), but I have to change my program so, that it works without “OPC Server”
@Putnam:
In the meantime I found out, why I got an error with “my modbus serial query.vi” (the solution was very simple, I had to close the OPC-Server ).
It runs now and I try to understand now how the VI exactly works.
Maybe you can help me with it?
I try to explain what I understood, if something is wrong, tell my please:
The “my modbus serial query.vi” allows to read the multiple values (maximum 125 register) (default block read size is 125) from controller (I can see the data in the register array). In each register I have values for different variables. The Modbus address of Loop1 PV (I need this value) is known ( 00001, Eurotherm manual).
Does it mean that the first element in the register-array is the value for the temperature from Loop 1 ?! (multiplicated by a factor, if it is correct, how can I find out this factor? It is linear?)
And if I need the value of Loop2 (the address is 01025), I have to set the start address for example to 1000 and in this case the 25-th element in register-array is the value for PV Loop 2 ?!
I got this idea, after I left the laboratory and could not try it out. I can do it first at Monday, but I would know if it is correct what I think.
If it is correct, I think I will able to change “my modbus serial query.vi” on my own, that it works in my program.
Or there is a better example/solution than “my modbus serial query.vi” ?!
The other problem would be writing of temperature, but I will ask about it later . First temperature READING problem!!
Thank you!
Alexander.

Exchange 2013 Upgrade to CU7 from SP1 - installs successfully - Can no longer connect via ECP/OWA/Powershell/Outlook/Autodiscover

Hi There,
I am having massive issues with my Exchange Server.
I have 2 Nodes, one has CAS and Mailbox Roles, the other just Mailbox.
I "upgraded" the CAS server to CU7 without any errors / issues.
Once I had restarted, nothing worked any more.. I couldn't access ECP, OWA, Powershell, Autodiscover or get outlook to connect.
I managed to get Powershell working, but changing the physical directory to "C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\PowerShell" from "C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\PowerShell"
But for the life of me I cannot get ECP or OWA working (haven't even tried anything else)!
I am getting a load of Events with ID 1003.
The only error I am getting is:
Server Error in '/ecp' Application.
Method not found: 'Boolean Microsoft.Exchange.Net.Wopi.WopiRequestPathHandler.IsWopiRequest(System.Web.HttpRequest)'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Which is almost meaningless... but maybe someone out there has some idea?
Unfortunately this is very urgent for me a these are production servers and currently there is no email for my company.
So Please please please can someone help.
I have tried many many many things from various sites, and so far nothing has worked.
Thanks,
-Tim

Hi Tim,
We can do the following steps to have a try:
1. Check Application settings in IIS Application under Exchange Back End web site for BinSearchFolders value.
a. Open IIS Manager. Expand Sites > Exchange Back End.
b. Click ecp. Open Application Settings in /ecp Home.
c. Please check whether the value for “BinSearchFolders” is changed to an invalid value.
2. Verify Authentication settings for OWA and ECP.
a. In IIS manager > Default Web Site, make sure Anonymous Authentication is Enabled in Authentication.
b. Confirm that "Require SSL" is checked on the root of the default website.
c. Make sure the Basic and Forms authentications are enabled in Default Web Site and Ntlm, WindowsIntegrated authentication methods are enabled in Exchange Back End for both OWA and ECP.

Can no longer connect via ssh

I've been trying to learn basic networking and have set up a website to upload files to. I've been using ssh in Terminal to do this. Until today I have had no problem connecting and logging into the hosting site and transferring files.
Now, after I enter my password, ssh does nothing, offers no response, takes no commands.
Any ideas on what happened and how to remedy this?
Thanks

Answered my own question:
opened another terminal window and used the command killall ssh to abort the previous session.
Still don't know why it won't login to my server.

Connection to serial port via USB adapter- error -2147221503

I am trying to drive a stepper motor provided with possible Labview or VB programs. This motor is supposed to be connected via serial port, but the computer has not some, so I bought an USB adpater to connect my motor via USB. I am using the labview programs provided (Labview 8.0). The program cannot connect to the port and returns error -2147221503. Where may I find some help with that ?
Thanks
Attachments:
error labview.JPG ‏234 KB

I see references to 'Luminos'. Is this the provider of the stepper motor and LabVIEW code? If so, your first step should be to contact them. The whole VI is nothing but ActiveX properties and methods and the vendor would be the only one who knows what is going on.

Can no longer connect to ASA 5505 (serial or ssh)

I have an ASA 5505 running software version 8.0(4) that I picked up a while back. I had just finished configuring it via the serial console. I confirmed that DHCP addresses we're being pushed out on the VLANs, made a couple of minor tweaks, and confirmed that I could ssh into the ASA on the appropriate VLAN. After that I issued a write to save the config and took the firewall downstairs to replace my cheap little router.
After hooking it up, I started checking my machines only to discover that none of the machines on any of the vlans were getting IP addresses. I assigned a static IP on the VLAN with management access but I still couldn't connect to it. A packet capture showed zero traffic coming from the ASA. I grabbed the ASA and hooked it back up via a serial console but now I can no longer connect to it. The power & status lights are on. Plugging in cables turns the link lights on in front and back and they flash indicating activity. When I unplug the ASA I see a single odd character show up in putty over the serial connection.
I'm out of ideas. Is there anything else I can do?
Thanks.

Step three of the password recovery option says, "During the startup messages, press the Escape key when prompted to enter ROMMON," but that pre-supposes that I'm seeing some output on the serial console. I'm seeing nothing at all (until I turn off the ASA then I see a single odd character).
Despite not seeing the usual console output, I've tried hitting repeatedly Escape as indicated but I'm still not getting any output. I've even tried other baud rates.
Thank you for the suggestion. Other ideas?

How can i browse FP 2000 via serial port same use Ethernet port(RJ 45)?

I am a new user for labview.I develope my program with FP 2000 but I have some problem
1 How can i browse FP 2000 via serial port same use Ethernet port(RJ 45)? if it can Tell me please.
  2 If I use GSM/GPRS modem via FP 2000 rs 232 port (I under stand how to send AT command) and leave it stand alone
     Can I dial modem and browse file in FP 2000 same as use Ethernetport?
Someone please help me.Thank you very much.

Hi!
    First, I can say that your project involves many things, I cannot describe all features in the forum, and I'm not used with GPRS modems (my modems are base band serial modems...).
    Anyway, I would say that in your project you should proceed like this:
      1) Configure your FP 2000 module via MAX and ethernet connection;
      2) Download an embedded application to your module (build in LabView Real-Time)
      3) In your application, you should build a kind of serial port manager, and by the means of serial port you send/receive commands from PC.
    The commands from PC can include "Tell me the about the FP 2000 file system ", or "switch on line X", or anything you need.
   I think it would be difficult to use Internet exp, because you use IE with TCP/IP, and TCP/IP is over ethernet.
   I know that for Windows you can find some wrappers that make you "see" the serial port as an ethernet, but these wrapper do not exist under filed Point, and you shoul build one yourself!!!(and that's not easy).
    For example, to browse your files, you should build a VI that searches through your file system, and reports, via serial, the files present in a directory (it's an example....).
    About communication between GPRS modems and FP2000, I know nothing. I suppose that these modems accept serial inputs, so you'll have to configure your serial port on FP 2000 with the correct baud rate, parity, and so on..... and you send your data to the modem. The modem will transfer data in its way, no matter on how it does.
    To send data to your modem you shoud take a look to some Serial communication examples. What I suggest you, first, is to connect the serial port of FP2000 to a PC, and test communication between PC and FP2000, without modems. Just direct cable connection! If you're able to do this, insertion of modems is the next step, and should be quite easy. If you're not able to make the PC receive strings of data from FP2000, over RS232, adding modems is a further complication, and you won't come out of this mess!
   So, what I say, is just build, for now, a simple embedded application for FP2000, that, using RS232, sends data to a PC (you should see data sent with use of Hyper terminal).
    To build this application, use Instrument I/O --> VISA commands (VISA open, VISA write, and Property node should be enough, for now).
   Please, let me know if this helps......
    Have a nice (programming) day!

Can no longer connect to remote server via VPN

I recently installed OS 10.5.8, and have found that I can no longer connect to my server at work. The VPN itself (via PPTP) works fine, it's just that when I try to connect to the remote server (via Connect to Server) I get a dialogue saying 'A volume failed to mount.' A further dialogue says 'Sorry, the operation could not be completed because an unexpected error occurred. (Error code -6602)'
Has anyone found a way around this, please? I'm disabled and I need to be able to work from home – without the connection I'm stuffed! Obviously I've tried rebooting the machine etc, but nothing seems to help.
Thank you for any assistance you can give.
Kitty.

For some random reason this connection has begun working again – please ignore the question!

I recently installed itunes update and can no longer connect to network nor internet

I recently (sept 2013) installed itunes update and can no longer connect to a network nor internet wired /wireless. I know it is not the gateway as other devices work. Please help. I am not very knowledgable so exact instructions will be most helpful.

Try connecting your computer/laptop directly to the base station with an ethernet cable to one of the external ports and install your network settings. If it finds it there, it will find it after you've reloaded your network info to the base via the Apple Utility. Hopefully when you disconnect afterward, all will be fine. Be sure not to select "closed" network although Macs will login with no prolem, PC's have trouble doing so even with the network data stored in the internet settings.
Good luck!
