(104) Connection reset by peer

Dears,
I have a web Application which works fine when accessed from other machines except one. Only in that machine I get an error
**(104) Connection reset by peer**
Please help me to solve this problem.

Even I thought that it is a bug in JSP. Good because it is.
But if it a bug then the issue should occur in all the computers, why is it from a specific computer? I don't know. Some really bad coding?
We could not reproduce this issue from any other computers except that one.Doesn't really matter does it?
I mean you are the server and you are aborting the connection for some reason.

How to correct socket communications error 10054: connection reset by peer

We are running Lookout 5.1 (build 8) reading data through Modbus Ethernet Drivers and we are constantly getting "socket communications error 10054: connection reset by peer" alarms on the server. When I connect to the server file with a client file the client is experiencing communications problems including locking up when editing, trends not showing up, stops updating completely (can only be corrected by restarting server file), and losing symbolic link.
Does anyone know how to stop this alarm from happening and if this could be the cause of my faulty server-client connection or is this strictly a problem between the server and the ethernet radios in the field?
Any response would be appreciated.
Thanks!
Jason
Jason Phillips

DST1,
All I had to do was increase the receive timeout in each driver's properties until the socket errors disappeared. I have them all set to 30000 msec. Communications have been great on this wireless ethernet system ever since.
Sorry for not answering sooner - needed to make time to go back and look at the file and then TS Lee came our way!

Failing to upload a file on storage account with "[Errno 104] Connection reset by peer" message.

Hi All
I am trying to upload a file (5GB) to storage account using put page blob api of azure python sdk.
example- blob_service.put_page_blob_from_path('container', 'windows.vhd', '/mnt/23/Windows.vhd').
But after sometime connection gets reset, i am getting same error in other regions as well. Following is the connection reset log-
>> blob_service.put_page_blob_from_path('container', 'windows.vhd', '/mnt/snapshotted_images/23/Windows7-flat.vhd')
*** error: [Errno 104] Connection reset by peer
Thanks,
Vaibhav Kale

Hello Vaibhav,
Directly uploading a 5GB file may last long time due to client network, then in that time period, if certain network latency or exception happens, then the upload action will be impacted.
To overcome this type of issue, you can consider to apply existing tool to upload vhd: azcopy
http://azure.microsoft.com/en-us/documentation/articles/storage-use-azcopy/
http://blogs.msdn.com/b/windowsazurestorage/archive/2012/12/03/azcopy-uploading-downloading-files-for-windows-azure-blobs.aspx
you can either start the tool by your python code to upload the target vhd file or manually run azcopy command to upload(if this uploading happens very rarely to you).
in azcopy, as the tutorial, there is option for you to specify the target blob to be page blob:
/BlobType:<block | page>
Specifies whether the destination blob is a block blob or a page blob. This option is applicable only when uploading blob; otherwise, an error is generated. If the destination is a blob and this option is not specified, then by default AzCopy will create
a block blob.
hopes this helps in your project.
In addition, I tested the python sdk here
https://github.com/Azure/azure-sdk-for-python, as it described, the function for create page blobs (from a stream, a file, or a string) worked for me. could you also try to reload this sdk and test?
let me know if there is any question.

WSAECONNRESET Connection reset by peer every 10 min

We are getting an error WSAECONNRESET Connection reset by peer every 10 min. We are running SAP on windows Small Business Server.
If I log in on server or within LAN it is working file without any problem. When we use WAN or outside network and connect SAP using SAP router it is giving an error of Connection reset by peer every 10 min.
I have reviewed OSS 155147 - WinNT: Connection reset by peer, 107407 - Win95: Connection Reset by Peer and 500235 - Network Diagnosis with NIPING without any success. I have played with registry parameters as per OSS 413330.
Could any one explain how to resolve this problem?
Thanks in advance...

> But the consistency is It reset exactly every 10 min.
Maybe you connection (whatever technical kind it is) resets connections all 10 minutes, maybe a firewall tears down the connection after that time... without knowing anything about the infrastructure I can just guess.
If the system is running internally fine without any interruptions then it's not a problem of the SAP system.

Rdesktop Connection reset by peer

Hello,
When I try connecting to a Vista system on my lan with rdesktop, I'm getting this failure:
$ rdesktop <ip_address>
Autoselected keyboard map en-us
ERROR: recv: Connection reset by peer
Based on some findings via google, I have also tried
$ rdesktop -n <hostname> <ip_address>
with the same result.
Since rdesktop is mentioning the keyboard map, I'll mention that I have
KEYMAP="us"
in my rc.conf
This system is very clean and bare. I installed ArchLinux x86_64 today and have just about as minimal of a system as one can have to attempt to use rdesktop.
Thanks

I use the same command and it works fine with me. Are you using a router? Are you using the public ip adress? Did you assign a static ip on the windows machine? Are you able to connect to a different server over the internet via RDP? Can you telnet to the windows box from linux on port 3389? what about testing vnc on the windows box and trying the same things. What im trying to see if its a network or software issue. If your able to use vnc or the port is indeed open to connect then its a software issue. If you can't see the port open or can't connect then its a network issue. because the port should be open.
EDIT: Can you please post your rc.conf as well? Also what DE are you using?

Microsoft Remote Desktop displaying "Connection Reset by Peer"

Server Side Configuration:
RDS Gateway Server: MS Server 2008 R2
RDS Web Server: MS Server 2012 R2 Standard
RDS Server: MS Server 2008 R2
Client Side Configurations:
Dell OptiPlex 9020: MS Windows 7 Enterprise with MS RDC [will refer to as DELL]
Apple iPad Air: IOS 7.1 with MRD 8.0.5.24403 [will refer to as IPAD]
Apple MacBook Pro Retina: OS X 10.9.2 with MRD 8.0.5 (Build 24428) [will refer to as MAC]
First off, this setup is in production and has been working great for all our remote users internally and externally for more then a year. This is our first Apple client to try and connect. I'm pretty sure it's not the server side of things.
I have tested all three client setups decried above on the same internal network and form the same external Internet connection.
The DELL and IPAD connect both internally and externally. The MAC will not connect internally or externally. The error box that is displayed simply states "connection reset by peer."

Always suffer "connection reset by peer" while performing software update

Hi all,
I just bought a brand new macbook air. The first thing I do for this laptop is to perform the software update. It suffered me for a long time that I always encounter the error message
"Connection reset by peer The Installer package has been moved to the Trash. To try again, open the package from the Finder"
For some update that the file larger than 10Mbytes, the error is very easy to occur. I will be ever lucky that I could download the update package for larger update file.
I can make sure that my network to wireless route is well as I could download 500Mbytes file manually from internet without any problem. Actually, I had downloaded the mac X OS 10.5.4 package manually and upgrade the system from 10.5.2 to 10.5.4 as it is almost impossible for me use "software update" to download about 500Mbytes without "connection reset by peer" problem.
Any input is appreciate.
Thanks.

I have the exact same problem , can any one please help with this
Thanks

This problem can not be reproduced. The problem happens only occasionally when the network is under heavy load and new DB connection is being created.
The application
The java web-application uses a customized connection pooling against the database. This pool is shared among all the users of the website. whenever a user process needs to fetch data from the database, a free connection from this pool is allocated. The application is testing if the connection is valid before making a transaction (select '1' from dual). When the error occurs a ORA-3113 end-of-file on communication channel is returned to the application.
The path between the client and db involves at least two firewalls. The firewalls are opened for sql*net traffic. The network group can tell that enquiries from the app.server is not getting feedback from the db. They have not however, identified if the enquiries are reaching the db-srever, or if they are stopped earlier in the network.
Around 1000 users, are using other applications which uses dedicated sqlnet connections against the db and they have not experienced any problems.
Issues considered
Connection pooling
It is a customized connection pooling, developed by Lindorff developers.
I have read through the source code for the connection pooling and it does the job as it should, and in case of bad connection, it tries to create a new connection.
The log file shows that the call to the method DriverManager.getConnection() hangs until the server goes down, which is probably because of the fact that the method DriverManager.setLoginTimeout(), does not take effect and timeout value is Zero. ( According to oracle , Oracle JDBC does not support login timeouts and calling the static DriverManager.setLoginTimeout() method will have no effect).
Firewall
One thing to consider is when the firewall may decide to shut down the socket due to long inactivity of a connection. This will cause problems to JDBC Connection Pool because the pool is not aware of this disconnection at the TCP/IP level; until someone checks out the connection from the pool and tries to use it. The user will get a Socket read error: connection reset by peer.
Jrun timeout paramter is less than the firewall�s timeout so the firewall will not close a connection before Jrun does.
Number of processes the DB can handle
Processes parameter is 1300, , they have not experienced the Oracle error msg �max # of processes reached�.
Port redirection through a firewall:
Since the firewall has a sql net proxy Port redirection through a firewall is not a problem. Problems with port redirection only appear at connect time, but in this situation the connections fail long after the connection is established.
The network group
The network people who investigaged the problem at Lindorff report that there are a significant amount of "dropped packages" between the database server and the jdbc client (web-application) 24 hrs. The reason for this is "unknown established TCP packet" which means that the firewall does not consider these packages to be part of an already established session. The network group believes this happen because one of the hosts send a RESET or FIN signal which the firewall have noticed but are not received by the other host.
It seems like the firewall are dropping packages bacause of "Unknown
established TCP packet" from both the JDBC client and the TNSLISTENER on the database server. The dropped packages are SQL*Net v2 traffic so clearly Oracle products are involved

Presumably something is working.
Thus the problem is not with your code. At least not the database part that you have control over.
That error occurs when the other side closes the socket. Presumably you are catching lost connection exceptions and trying to restore it.

How to fix "DRM Error 3321" withouting connecting PC to internet?

How to fix "DRM Error 3321" withouting connecting PC to internet?
Currently, we are encountering "DRM Error 3321" because our PCs/Notebooks do NOT have connection to internet for “http://individualization.adobe.com”. Thoese PCs are in isolated network and can NOT connect to internet.
Is there a way to solve this issue without connecting their PCs/Notebooks to internet?
Thank in advance.

Hi Soe,
Unfortunately there is no way to resolve this error without connecting to the Internet at least once. This initial connection is required to create and download the device specific key as mentioned in this post (http://forums.adobe.com/message/6240315). Once you have established that initial connection, you can play content offline assuming your content licenses are constructed correctly. Some content providers will require at least an initial connection to their license servers as well, although once you have the device specific key you can play files protected with PHLS or PHDS without further license acquisition.
If you are content provider, you can find more details on how to do protect your content for offline playback here:

Protected Streaming (http://www.adobe.com/support/adobeaccess/pdfs/server/AdobeAccess_4_ProtectedStreaming.pdf)
This is probably not the answer you are looking for, but hopefully this helps a little.

Netscape Error: Connection reset by peer

          I am running a JSP application on weblogic and when I view in Netscape 4.08 on
          W2K I am getting an error saying Netscape Error:Connection reset by peer. Anyone
          else see same error. Any fixes?


do u see this on the 5.1 line ?
          Netscape needs a content-length for every response that comes in, and in case the
          response is larger than the buffer size, the content-length isnt set and netscape
          keeps hovering even after getting all the data.
          When it sees that the connection has been closed from the other side, it thinks that
          the connection has been reset. (even after the server sends it a Connection: Close
          header)
          solns can be summed up as:
          1. call response.setContentLength whereever possible
          2. increase the buffersize of jsps (there might be an upperlimit though)
          3. move to another version of netscape (atleast > 4.7 ) on win2k
          let me know how the workarounds are
          thanks

This is generally a Lion error.. and you will need 5.6 utility to get access to the disk area.
So download the real utility. Run it instead of v6 toy version.
http://support.apple.com/kb/DL1482
Go to the manual setup, disk page and click on disconnect all users.. that will unmount all users connected to the disk and allow it to start working. But there are a number of other issues that are possible cause. Pondini lists some of them.
