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?
My system just crashed. kduffy101@kduffy101-desktop:~$ firefox WARNING: pipe error (3): Connection reset by peer: file ./src/chrome/common/ipc_channel_posix.cc, line 404 Segmentation fault kduffy101@kduffy101-desktop:~$.
When I do an amcheck, I get this Amanda Backup Client Hosts Check WARNING: noname.com: selfcheck request failed: recv error: Connection reset by peer Client check: 1 host checked in 0.022 seconds. 1 problem found.
I am using bsdtcp. I get an ack error if I switch the client to bsd authentication. What should I do, how do I fix it? I read that I should enter servers address to hosts file in /etc/ directory? Here is the log in /var/log/messages:
I am a system administrator and i have configured squid server at the server side.Now i am facing a problem that these two websites are not accessible through squid transparent proxy server while they are accessible when changing the gateway.The websites are following:-

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 10.1.1.2 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.
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?
When I plug in my iPhone to my 10.04 machine, it's recognized. I can always drag music from the iPhone to the Music collection in Rhythmbox, but 9 times out of 10 dragging the other ways gives me this error:
"Error while getting peer-to-peer dbus connection: The name :1.219 was not provided by any .service files"
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:
Quote: Feb 9 14:19:20 harriet sshd: Accepted password for xxx from xx.xx.xx.xx port 55105 ssh2 Feb 9 14:19:20 harriet sshd: pam_unix(sshd:session): session opened for user xxx by (uid=0) Feb 9 14:19:28 harriet sshd: 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.
I'm trying to connect with my server via telnet, but when i sent the command (telnet xxx.xxx.xxx.xxx Port) doesn't works and shows then follow error: Unable to connect to remote host: Connection refused, It happens with any port. Is strange but my telnet services works (telnet xxx.xxx.xxx.xxx), In addition, i tried with firewall enabled and disabled and the problem still happens. My centOS run on virtualbox.
I'm having problem running open SSH. I have installed SSH, on my system, but when I run:ssh localhost.I get the error :Read from socket failed:Connection reset by peer.I get that same error when trying to connect from a different local computer.When I attempted to restart the service by typing: sudo /etc/init.d/ssh restart.I proceeded to generate a new set of keys by running, ssh-keygen -b 1024.But I get the same errors after doing so.
I'm still kind of a linux newb, so I might just be missing a little bit of knowledge here, but I've been having some real problems getting my machine to connect to my wireless network under Ubuntu 9.04.
OSes: Windows XP Home Edition (on Maxtor internal drive) Ubuntu 9.04 (on WD internal drive)
I don't think my video card would make any difference, so I won't list it on here...
Anyway, what happens is I try to connect (I select the network SSID from the pull-down list in the NetworkManager panel menu), and it seems to connect okay to the router, but I can't get out to the net. I can pull up a terminal and ping the router's address, but I get a "Destination Host Unreachable" message. It's as if, to the computer, the router isn't even there on that level, but it can still somehow connect to it.
Now, here's the strange part. If I reset the router from another (Windows) computer on the network (specifically, the one with a wired connection to it), then I can connect just fine and I can get out to the internet.
Even if you don't know specifically, but have some good ideas as to what might work, that's fine too. I hate having to do this every day, as it affects everyone's internet connection. Granted, it's not like I'm in a strict business situation with tons of machines and multiple access points, but there are 3 of us in the house and we all share internet access from the same router (as I'm sure most people do), and I feel kind of guilty having to interrupt everyone's connection, if even only for about 30 seconds just so I can get a net connection under Linux.
Windows connects to the router/internet just fine, btw. No problems there. I'm also using a NetGear WN111 USB wireless adapter, with the Windows drivers under ndiswrapper.
I am using Ubuntu 10.4 LTS and Samba3.4.7.I have read a lot of posts and different web pages on setting up Samba on a Peer-to-Peer network with Windows XP but just cant make it work. I can see the Guest account in XP My Network Places but cant access the folder when I click on it.Network not accessible or you dont have permission. I can PING both ways ok. I have Firestarter turned OFF and I dont have any third party firewall on XP.
This is my samba config file:
[global] netbios name = dolphin server string = Ubuntu workgroup = WATERLILLY - same as XP
i have an embbeded hardware that uses bootp for booting from a Network Managemnt Host (NMH)on the same ethernet. The embedded hardware has both kind of ports i.e ethernet as well as E1/T1. I would like ask, what do i require to establish a communication-link between the embedded hardware and the NMH throuh E1/T1 ports of embedded hardware, so as to make it boot through from E1/T1. Further, NMH possesses only ethernet port. Just to refine my questions i'd like to know what additions do i need to do on my NMH , like may be i have to put an E1/T1 port or is it possible that the E1/T1 port can be directly connected to an ethernet port on the other host.
pardon me if i am not making absolute sense here as my knowledge is limited on Layer 1 and layer 2.
I am running Ubuntu (Karmic) and did the command: "sudo apt-get install ssh", In an attempt to download, install and setup OpenSSH. This installed both the client and server and during setup actually brought the daemon up and running as well. I then attempt: "ssh <myusername>@localhost" and it prompts me with a password. I enter the password, hit enter and immeditaly see the following results:
Read from remote host localhost: Connection reset by peer. Connection to localhost closed. I'm fairly certain that it is not on the client end as I can connect to other machines through ssh. I've tailed all the logs, messages, dmesg etc and nothing seems to be out of order, or even remotely related to shh or connections etc. My desktop machine had no (as in zero) issues installing and setting up OpenSSH, and connections can come and go as normal.
I AM able to connect from CLI using sftp to the ftp server using port 2222.
Code:[URL]... I can ls/dir on the server as would be expected. However, if trying to use either bareFTP or filezilla I keep getting errors on trying to connect to sftp. I have gotten a range of errors from "reset by peer" to "Pageant unreachable". I have been thinking it is my firewall, so I flushed out bound and set to ACCEPT to test. INBOUND was set to allow ESTABLISHED, RELATED. I set up a log rule to catch everything which didnt show any drops on my side ( I may be reading them wrong though).
My problem is that the Mailserver in OpenSuse 11.1 (postfix, amavisd, spamassassin, clamAV en Razor) can not recieve e-mails, outgoing is ok. The problem started when I added 2 new users to de LDAP-server connected to Postfix.Some users can login, but most of them are getting the error: cant connect POP3 connection refused port 995.
having a port 22:connection refused problem with SSH. None of what I have read has been what I have been experiencing, so I figured I would post here. The worst that could happen is this gets completely ignored, or I am told that there is already a solution, that I missed it, and directed to it. Here is my problem:
Just learned how to ssh into my machine a few days ago. Everything has been running smoothly until I ran into a little problem: all of a sudden I can't connect anymore. I have sshd-server installed and updated. I have sshd turned on
Code: /sbin/service sshd start And I even ran:
Code: /etc/init.d/sshd start Because I was told that it would start ssh from boot. Nothing has changed from today and yesterday and I haven't been having problems with port 22 being blocked.
I have also tried to ssh into the machine by the machine itself:
I want to view the files for RepRap, but do not know which java files to install. Here is the error readout from running the reprap shell script.
Code: keeper@keeper-netbook:~/Desktop/reprap-mendel-20100105$ ./reprap Exception in thread "Main" java.awt.AWTError: Cannot load AWT toolkit: gnu.java.awt.peer.gtk.GtkToolkit at java.awt.Toolkit.getDefaultToolkit(libgcj.so.81) at java.awt.EventQueue.invokeLater(libgcj.so.81) at javax.swing.SwingUtilities.invokeLater(libgcj.so.81)
I get a connection refused error whenever I attempt to connect to a remote ssh server, I tried the test at and it says outbound ssh port 22 is not being blocked. I'm wondering what else could be the problem.
My organization just moved to using a zscaler proxy system. Basically, I have to use a .pac file in Firefox to get onto the proxy, which directs me to a series of two Flash pages, one to input my username, one for the password. After reading through the .pac file, I was able to get some command-line things to work by specifying the proxy given at the end. However, this server uses an SSL certificate that is not emitted by an authority, but rather directly by our organization. In Firefox, I had to import this certificate to enable https:// browsing.
Is there any way to "import" this certificate so that yum can use it? Because yum freezes with the error: Code: Could not get metalink [URL] error was 14: Peer cert cannot be verified or peer cert invalid
I have a Windows machine on which NX Client has been installed. I wanted to test if I could access my Ubuntu box. The Ubuntu Box has NX Server, Node and Client installed. When I try to log in from the Windows machine using NX Client with my Ubuntu username and password I get an error connection refused.
The following service is running: OpenBSD Secure Shell server sshd How can I resolve the issue?
