We have one FTP server. Users are uploding files to the perticular directory remotely. but today some users got below error message.
421 Service not available, remote server has closed connection.
(vsftpd service is up and running) What are the possible causes for this error and from where I should start troubleshooting?
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.
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.

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 --

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 have recently installed fedora 14 and configured vpn to access my work network. I need to access some windows machines which although I can ping I cannot remote desktop into. When I go to Applications>Internet> Remote Desktop Viewer and put in the machine name (either just the machine name or the FQDN including the domain name) I get an error "Connection to <machinename> was closed".
View 4 Replies View Relatedi try to connect to a specific ip address with ssh i have installed the ssh server and client. i also try it by connecting with localhost without any problem. But i keep taking this message if to try to connect to the ip address. i checked my hosts.allow and hosts.deny files and all are commented in there (i think tha this should not be the problem).
View 2 Replies View RelatedI 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

View 2 Replies View RelatedIn 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 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?
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 ?
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.

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 am facing problem while connection to host (Red Hat Enterprise Linux ES release 4 (Nahant Update 5)) via putty.

I have a windows 7 box and a debian 5.0 box connected to a linksys wrt300n router. I can access the linux box from windows 7 through ssh. I used to be able to access the linux box from outside the LAN, but when I was messing with the ssh port configuration (at least I think this was what happened), i lost my ability to connect. I tried writing a new sshd_config file so that it is much simpler:
Protocol 2
PasswordAuthentication no
UsePAM yes
I tried directly connecting the linux box to the internet to rule out a router firewall issue that i was missing. iptables -L yields nothing, as I have since rebooted the machine since messing with iptables rules. But still, when I try to ssh in from outside the LAN, I get a connection timeout error after a 10-15 second hang.
I have local and remote networks that have various printers. I can add any printer (local or remote) to any PC, except for one PC that's refusing to allow remote connection (it used to, but doesn't now!). The problem PC has two printers connected and work OK as a local printer, but both display same problem when attempting to connect from any remote PC via YaST. Using 'Connection Wizard> CUPS Server' connection method requires IP address of remote PC and printer name. But if I correctly select either of the two printers I get an error message:
"PING 192.168.1.149 (192.168.1.149) 56(84) bytes of data.
64 bytes from 192.168.1.149: icmp_seq=1 ttl=64 time=1.12 ms
Both printers are set to 'Accept Print Jobs' and 'Share Printers> Allow remote access' permits all networks to connect. why this PC is requiring the root password?
