Networking :: Multiple FTP Upload Socket Error "Connection Reset By Peer: Socket Write"

Jan 31, 2010

I am pragmatically trying to upload a list of files from my client machine to a proFTPd server I have running on Ubuntu. Every time I get several (around fifty) files into the transfer, I get the following error: Quote: Connection reset by peer: socket write error

I am able to remotely upload 25,000 small files of ~ 1K in size, but when I go to upload hundreds of 2-4 Mb files, I get a socket write error. Am I using up all available sockets before they can be released? If so, how do I release the sockets? If not, what does this error mean and why am I getting it?

Ubuntu Networking :: Ssh "Connection Reset By Peer" - Write Failed: Broken Pipe

Feb 9, 2010

which cropped up today after no changes to the system: I can successfully ssh into my ubuntu 64-bit 9.10 machine (via OS X with iTerm), but after about 30 seconds, the connection drops with the message "Connection reset by peer Connection to xx.xx.xx.xx closed".

If I then try to immediately ssh back in I get: "Write failed: Broken pipe". If I try to immediately ping the machine instead, I cannot ping it until the ~10th try. Eventually I can log back in again, only to be kicked off after between 5 and 60 seconds. I called the network people and their are no known issue right now with networking. The networking on the ubuntu machine is otherwise fine, it seems. In the /var/log/auth.log file, it simple says:

Feb 9 14:19:20 harriet sshd[4134]: Accepted password for xxx from xx.xx.xx.xx port 55105 ssh2
Feb 9 14:19:20 harriet sshd[4134]: pam_unix(sshd:session): session opened for user xxx by (uid=0)
Feb 9 14:19:28 harriet sshd[4046]: pam_unix(sshd:session): session closed for user xxx

The solution I come across to a similar problem is to add a "ClientAwakeInterval" number to sshdconfig, but this (as expected) doesn't fix my problem.

Ubuntu Networking :: Port - "connection Reset By Peer" Error

Jan 27, 2010

I have an external hd attached to my one computer at home, use DynDNS to give it a static address, and can usually ssh into the machine fine. I ran update a few days ago and now have the much-aligned "connection reset by peer" error. I checked the machine and made sure everything was "normal;" e.g., checked ssh config for the port change (correct), doubled-checked ufw to make sure the port was open (it was), etc. I ran nmap on the machine and it said the port was open. This morning when I arrived at work, I ran nmap on my machine here where I've been unable to connect and its results were a little surprising: the port I specified at home and was demonstrated as open is not. WTF?

Ubuntu Networking :: Rdesktop Connection Reset By Peer

Jul 15, 2010

I've happily been using rdesktop to access my MS Vista desktop from Ubuntu (Hardy) for a few months until a couple of days ago when it stopped working. Now if I try connecting I get the following:


I don't believe anything's changed on the client (Ubuntu) side. The Vista box is occasionally connected to a corporate intranet via VPN and it was after such a session that rdesktop stopped working, so perhaps a Windows group policy was modified during the session. I've checked the basics - can ping from Ubuntu, can access port 3389. Have deleted ~/.rdesktop and ~/.tsclient.

Digging around the Vista client I noticed in Control Panel > System Properties > Remote that in the Remote Desktop sub-panel the Allow connections only from computers running Remote Desktop with Network Level Authentication setting is enabled and that the other two are greyed out. Now, I don't know whether this setting has been changed but I suspect that it might be the problem.

Unfortunately, I don't know enough about Windows to know how or even whether I can change this setting to Allow connections from computers running any version of Remote Desktop (less secure) I've poked around the group policy editor (gpedit.msc) but no joy.

Ubuntu Servers :: VPN Setup Peer Negotiation Failed

May 23, 2011

I've followed [URL] to set up vpns with some external networks. So far it worked like a charm on two of them. But when trying to connect to the third one I instantly get bumped off.

When running

I get this as part of my output

Script pptp xxx.xxx.xxx.xxx --nolaunchpppd finished (pid 8920), status = 0x0

I've looked all over the internet but sollutions like adding mmpe-stateful to options.pptp doesn't work. Is this a problem with the client or with the server? Because the server is configured just like the other two and they work as intended. Seemed to be a problem on the firewall.

Ubuntu Servers :: Maximum Simultaneous Socket Connection?

Sep 16, 2010

I'm writing a client-server program. There are more than 500 clients. I start a thread to process and response to each client and the processing needs some MySQL query. I'm looking for any possible hazards on my server!

1- Any limitation on "Maximum Simultaneous Socket Connection"?

2- Any limitation on using mysql?

3- As socket on Linux are file, Any limitation on number of sockets or threads?

I'm using a Linux server (Centos or Fedora or Ubuntu) and clients are both Linux and Windows.

Programming :: Timer In Socket Programming - Wait For X Sec After Read() And Then Disconnect The Client Connection

Mar 8, 2011

I have a server listening on incoming client connections. Once the client establishes SSL connection with the server, the server waits on read() from the client. Only Client can disconnect the connection. I want to have a timer in the server program to wait for x secs after read() and then disconnect the Client connection.

Ubuntu Servers :: Unable To Connect To System Bus: Failed To Connect To Socket

May 29, 2010

I tried to install vsftpd on my server and while the installation went fine, I can't run

restart vsftpd
As I the get error

restart: Unable to connect to system bus: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory Though I'm able to restart the service with

sudo /etc/init.d/vsftpd restart with a warning telling me to use the service utility. Not only that, but despite the port being open it won't allow me to log in, it just hangs, and I have local users enabled (I've used the default .conf file). Does dbus not come installed in 10.04, and if I did install it would it make a difference for restarting the service? Are there further steps needed not available in the tutorial on the Ubuntu Server Guide for 10.04 to enabling local user authentication? -edit- Figured it out, dbus wasn't installed, vsftpd is working fine now.

Im just trying to set up a server to pass messages from a client to it a viceversa. Here is the code:

Ubuntu Networking :: Peer To Peer Filesharing Between PC's

Mar 2, 2010

I know I'm missing something absolutely basic here but when I search the forums for filesharing I only seem to get info referring to Windows filesharing/SAMBA etc.

We have 3 Ubuntu machines at home and a printer on a Windows machine. How can we best fileshare:

1) between Ubuntu machines
2) reliably between Ubuntu and the Windows machine

Printing across the network is ok except for the Karmic NBR machines but that's another thread.
