Debian Configuration :: Connection Closed By Server With Exitcode 141
Sep 4, 2011
setting up an SFTP server on debian, all the way down through step 3, though I did not "Match Group" I did Match User as I only need 1 user to have access to the SFTP server(did not continue on to step 4 and beyond as they did not apply to me) Im getting the error:
connection closed by server with exitcode 141
I get this when trying to log in via filezilla. I actually only got the 141 error on the first attempt, any attempts after that just says "could not connect to server". Username and password authentication goes through, so it is not a login info issue.Im running Debian squeeze, and that guide was for Lenny, that shouldnt matter, I dont think.

I'm a frequent user of the shared connection feature of SSH. Usually i have two or three connections open at the same time through the connection sharing feature, but sometimes when i try to start another i get the message "Shared connection to <server< closed". All the connection that are established through the connection sharing feature are still active and not closed, but when i try to create a new one i get that message.. i've even got that message when i have only had two connections through the shared connection feature.
I've tried to search google but it doesnt seem like anyone else has had the same kind of problem, does someone know why i sometimes get this error ?

I'm using Postgresql 8.4.2-2. I'm trying to remote into my server securely. I figure I could do so with ssh. Apparently I figured correctly, as per, [URL] and [URL] I setup the ssh tunnel. ssh -L 5432:serverip:5432 Then I setup pgadmin3 to connect as follows:
host: localhost
port: 5432
user: postgres
maintenance db: postgres
And I receive the following error:
An error has occurred: Quote: An error has occurred: Error connecting to the server: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.
I'm not sure what the problem is. I can connect with Code: psql from the cli after connecting to the terminal via ssh. So I know that I'm using the correct password.

My IBM Thinkpad T42 laptop fan is constantly running when the laptop is open.I only use AC power.Fan turns off when laptop is closed, which I did by selecting Suspend in Power Management.
cpufreqd and cpufrequtils are installed. cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor' is 'ondemand'
Constant fan was not a problem in XP Pro; I just installed Debian one month ago.

In my case, it occurs intermittently when trying to connect using putty's command line client 'plink.exe' to a linux machine using ssh. For some testing purposes, a linux server is setup with 8K virtual ip addresses and the testing scripts will connect to these ip addresses through ssh using plink.exe. There will be concurrently 25 ssh sessions launched to the server. While it works for sometimes, it throws 'server unexpectedly closed network connection' error intermittently. If the same ip address is tried again manually, it works. While the ssh server is accepting connections, this error is thrown sometimes and unable to find out the reason from the logs. It is not that the ssh connection is completely blocked. It gives this error message while connecting to some of the virtual ip addresses but works some times.
The hosts.deny, sshd_config are tuned to allow the connections, allow more sessions etc.

I can ssh to my Fedora 12 without any problem, but every time I sftp to it, it says "Connection closed" and then just kick me out. Is there any configuration I missed here?
I found the issue is that in .bashrc I have following line: bind '"C-a": "cd .. "' As soon as I comment it out, sftp start working. But I cannot explain it.

I have a java application that I wrote recently. It runs off port 9955. The application runs great on my mac server. When I installed it on my linux box i cant get to it from outside the box. A port scan shows the port as closed. I flushed my iptables, did not help. I can telnet into the app locally, from the server and it works great. I cannot telnet from outside the server. I have a reference to the application in /etc/services as a tcp port (which it is).
netstat shows it as listening
netstat --listen
tcp6 0 0 [::]: SimpleSocketTest [::]:* LISTEN
netstat -anp | grep 9955
tcp6 0 0 ::: 9955 :::* LISTEN 1484/java

I have configured rssh 2.3 with openssh 5.8 on RHEL 5.6 64 bit to restrict the users to scp and sftp. When i try to sftp or scp it gives error connection closed. After long googling tried different solutions like add missing libraries, setuid to rssh_helper. I had full copy of /lib to /chroot/lib and /chroot/lib64 but no success. conf and log files are below for reference.

We are having an issue where our network connection is dropping on our server. Everything was working for about a month without issues then suddenly we experienced a network outage. Here is what I found in our logs. Rebooting the machine was the only way to have everything come up.

I have a problem between a jail root (so a group of users can access through sftp to Apache directory (var/www) an not get out of this directory.
1. I have the group 'sftponly', I need to access / var / www for sftp (read only)
2. On the other hand I need that user www-data (Apache) is the owner or at least have write permissions in the same directory (/ var / www)
The problem comes when the two needs together, as from what I read, to do jailroot in a directory is necessary for the owner is root and any other user has write permissions on it.
If along the jailroot with write permissions then attempt to connect to the client via sftp throws me the following error: "Error: Server unexpectedly closed network connection"
Permissions system User/group/Others doensn't work to me, so I tried it with ACL, but I have the same problem when I grant write permissions to the apache user.
Does anyone know how can I do for the user www-data can have write permission in the Apache directory and be able to create a user or group of users who are "locked"in this directory to enter sftp?

The situation: The office has a WiFi network on one DSL line, which is used for our VoIP call center, and a wired network for our internal network and the majority of web surfing/traffic . Part of the office must be temperature controlled/monitored - we have a rather nice digital thermometer which is WiFi enabled.I have a Debian Wheezy box with a WiFi card and ethernet connection
What I'm trying to accomplish:Connect wifi enabled thermometer to WiFi network so it can automatically send temp updates (currently I have to do it manually via USB)Have the Wheezy box accept the downloaded file then send it to a back up server in the wired network
Side things that may be useful : Prefer to use wired connection for internet and apt and suchWiFi connection will really just be used for connecting to the thermometer
This [URL] .... topic got me thinking that there might be a way to bring the two networks together, but I don't know if that will wreak havoc on things. I know, the Windows and Mac OS don't like having ethernet and wifi at the same time, might Linux be better for this?
v&n had this to offer in the prior thread [URL] .... which I'll be doing more research on.

As the title implies, I'm having an issue with svn, whenever I try to make an svn action, I get: svn: Network connection closed unexpectedly
I've done some Google-fu on this, and the obvious culprits don't seem to be at work. Specifically, the svn server does not use a nonstandard port, and I'm not using Tortoise SVN or putty, just going directly from the command line. Additionally, I was able to use the server as recently as this morning and no coworkers are having problems.

I have a weird problem with ssh, I am trying to ssh to a solaris server (sparc) running solaris 10 from my Ubuntu box and as soon as it authenticates the password it closes the connection. The box is located on a internal network in a wiring closet with no ability for me to access console but i still have a working ssh session from 2 days ago with what i'm trying to comb through settings and trying to resolve the issue. It also has 2 NIC's and I cannot connect to the either ruling out hardware problem. I checked if there is a limit of the number of active connections and the was no limit. I was able to connect mitiple session till 2 days ago (at one point i had on my machine 8 active ssh sessions to the same server).
Here is the output of ssh -vvv:

I have installed Fedora 13 and updated it. I simply cant use ssh to connect to this Fedora, not even locally. I have enabled port22 in firewall settings and nothing. Tried to disable firewall completely and nothing. I have disabled SELinux (not sure if it has something to do with this, but... ) and nothing. Entered "ALL: ALL" in /etc/hosts.allow and still nothing. Dont know what to do anymore.
Here is what happens when I try to ssh to this machine, even from it:
[flibio@surf ~]$ ssh localhost
warning: Need basic cursor movement capability, using vt100
flibio's password:
Authentication successful.
Disconnected; connection lost (Connection closed.).
Connection to localhost closed.
[flibio@surf ~]$
Looking into Services > sshd and it says "This service is dead."
So I tried:
[root@surf etc]# service sshd restart
Stopping sshd: [FAILED]
Starting sshd: : OpenSSH_5.4p1 on
: FATAL: Creating listener failed: port 22 probably already in use! .....
And still I get disconnected whenever I try to ssh to this machine from anywhere. Services says that sshd is allways dead, even restarting it but I can only restart it by doing a pkill sshd before.

I am having trouble connecting to one of the VM's through ssh from base machine all of a sudden. All I get is an error : ssh_exchange_identification: Connection closed by remote host
--IP/Hostname crossed out --
[root@XX-XX02 ~]# ssh -v 1XX.1X.5X.1XX
OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008[code].....
Saying that the problem is only with ssh would be wrong as I can't seem to telnet or ftp it either. But I can ping it fine.When I try to login to that VM through console, it won't even let me login. The screen would flash for a sec and the same login prompt would reappear. I am not sure what exactly happened as it was working fine before.

I'm forwarding an application (HandBrakegui) over an ssh tunnel using X11 forwarding as follows
ssh -C -p PORTNUM user@host -X ghb
This all works fine and X11 loads and handbrake's X11 output to my local mac.The server is Ubuntu 10.4 and the client is Mac OS X.Is it possible for the X11 HandBrake Gui session to be kept alive once the SSH tunnel or the X11 window on the client (mac) has been closed? As I'm adding files to HandBrakes queue I want the programme to finish encoding them even if I turn off the client computer as the server is always on.

Firstly I am new to red5 and not very strong when it comes to linux. I have had installed red5 on my dedicated server and going by the http://myIP:5080/installer demos it is all working fine. My problem is I cannot get it to work with my software being flashchat. I am not sure if it comes from me using the incorrect RTMP url and if so after trying about 20 or more ways of typing it in I always get the same error message "Connection Failed' or "Connection Closed" not to sure what is meant by Closed as to whether it's working but can't get in or what ever. I am after someone who can get this to work for me please and I am willing to pay for that service once it is working.

I have set up SSH and redirected the ssh server to listen on another port other than 22 for a bit of added security.
Now in hosts.deny I have:
ALL : ALL
In hosts.allow I have:
SSH : ip_address_of_client
I can no longer connect. I get the message: ssh_exchange_identification: Connection closed by remote host.
When I change hosts.allow to read:
ALL : ip_address_of_client
I can successfully connect the server.
However, I only want to allow SSH access in hosts.allow. What is the correct syntax?
I have tried and failed with each one of these:
SSH : ip_address:port_number
SSH2 : ipaddress
sshfwd-portnumber : ip_address_of_client
