Server :: All Connections Being Refused On LAN?
May 26, 2010
I have a little file server, which also acts as a printer server and it has a web server implementation for Mapserver too.
Suddenly, nothing can connect.
if I try ssh
Code:
john@john-desktop ~ $ ssh -vv 192.168.1.100
OpenSSH_5.1p1 Debian-5ubuntu1, OpenSSL 0.9.8g 19 Oct 2007
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
[Code].....
I am not running any software firewalls on any of the boxes, nor have I messed with anything on our router (Linksys Wireless-G)
Also, all connections are ethernet, not wireless, and the server and the other two boxes are assigned IPs - no dhcp issue

I've got SAMBA and SWAP installed. I tried to localhost:901 and telnet localhost 901 And both connections tries were refused. I opened the port and even shut down iptables. What else do I need to do to use SWAT?

I am merely trying to change the port for my ssh server.However it isn't changing.I edited my ssh_config file to:
Code:
# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for[code]...
When i try to connect to my server via port 443 i get a connection refused error. However when i try to connect via port 22 it connects. Since that didn't work, i tried restarting the entire server.To restate, i changed the config file and restarted ssh then the computer, however the port didn't change.Ohh and yes my router is set to port forwarding on port 443, though it doesn't matter since I'm inside the network.

I have configured openssh 5.8p2 with centos 5.6. My sftp is working fine with chroot environment but i am having problem with SCP. I am dealing with muliti Redhat servers. When i try to transfer data from other linux server through scp it gives connection refused. For e.g ssh 5.8 is configured on new server and i want to transfer files from old server which is using openssh 4.3 version.i created same username and password on new server as on old server.My sftp users on new server has no shell access but only sftp access. When i try to scp from old server to new server it gives error connection refused. Is the below configuration only for sftp and can't scp? According to google the configurations i found are for scp and sftp. Do i need to generate ssh keys by giving users on new server shell access, once created then stop shell access again, as i dont want to give shell access permanent for security reasons? but i want to use ssh keys for more security as well.
Port 22
PermitRootLogin no
1.override default of no subsystems[code].....

ENV: openssh-server-5.4p1-1.fc13.i686 Problem: I am unable to ssh using Putty (when using ssh-auth/pki) to a fedora box . I get the message: Server refused our key. Here's what I tried so far:
- Tried generating rsa (as well as dsa) keys on the linux server and put the generated public key in the ~/.ssh/authorized_keys. Then I converted the private key using PuttyGen.
- Also, tried generating keys using PuttyGen and then converted the public key and placed it on the server
- Configured the sshd server (ssh_config) for using RSAAuthentication=yes. Tried all combinations and purmutations; however, I still get the "Server refused our key" error.

I am experiencing a problem with Nagios running some checks on our Ubuntu 10.04 servers.
we have 16 Nos HDD in each servers. These HDD's are checking by nagios with CPU and users.
For whatever reason, all of the checks will come up with the response: "Connection refused by host".
We have checked the server at the time of occurence and all seems fine. No memory issues, no CPU issues etc.
Then within 5-10 minutes the problem goes away.

I have a box running Fedora 14 upstairs and I've been trying to get it to run VNC server, unsuccessfully. I've RTFM, and followed the instructions step-by-step, but it still won't run. I'm getting no error messages. But when I try to connect from either a Window or Mac client, it either get a timeout or connection refused. I've read and tried all the troubleshooting; been working on this for about 12 hours now. Is there something major that I could be overlooking?

I have configured a Nagios server which is working well with all king of clients. But when I added a new windows machine to monitor, it gives a error message "connection refused". I have set everything as prior machines.
Now, I just wanted to know the process by which we can check if server is able to communicate with the client's NSclient daemon. In Linux, we simply issue "./check_nrpe -H hostname" and if ok, it gives the NRPE version which indicates the status ok.

CUPS is stopped in the system and the system is configured as samba server. What could be the reason for these printing requests from smbd?

I am experiencing a bit of a problem with openssh-server. I installed the server like I normally do. It wouldn't work, so I tried using this. It still didn't work. Later, I have realised that when using service sshd start SSH says it started, but when you check if it's running with service sshd status it says it doesn'triend advised me to use /etc/init.d/sshd and I managed to get it started. However, that doesn't return anything, and when I try to connect it says connection refused even when I try to connect from localhost to localhost

I'm try to setup a database server using mysql, the server starts fine, and I can access it using the built in mysql client via console (adding databases and tables works fine), but the problem is... I always get a connection refused error whenever I access the database outside the built in mysql client (example, if I write a code that connects to mysql). So, I tried execute an nmap command and the only ports open are these ports:
[Code]....
there's no 3306 for mysql... I'm thinking that the firewall is just blocking the port that mysql is using, but my question is, how could the built in client connect to the server if there's no open port for mysql server? Don't clients usually access a servers through ports?

I have FileZilla installed on this machine, and OpenSSH (with an open port 22) on another machine on my home network. When I try and connect, I get: Quote: Status:Connecting to 192.168.2.3... Response:fzSftp started Command: open "alphatwo@192.168.2.3" 22 Error:Connection refused Error:Could not connect to server
Which has left me puzzled as I have an open port. Does the username have to be defined somewhere? E.g. the machine acting as my SFTP server can be logged on to locally as alphatwo so that's what I logged in as (with the correct password). Is this correct? If so, does anyone have any ideas as to how I might rectify it? I want SFTP set up so I can copy PHP files from my laptop to /var/www/html/ on another PC (across the home network).

I am trying to monitorize an OpenWRT (Backfire 10.03, r23115) router from an Ubuntu server, but I am having some problems. I have installed Nrpe (2.12) on the remote host (OpenWRT), I have executed the program as a deamon (/usr/sbin/nrpe -d) but when I start the NRPE deamon, I don't get anything about NRPE executing netstat -at or ps -ef.I would need to install check_nrpe on OpenWRT to find out if NRPE is working, but I can't find any ipk package with it. Now, once in the monitoring host when I try to reach the remote host from the server:
/usr/local/nagios/libexec/check_nrpe -H ip_remote_host
I get: Connection refused by host
Even, trying with localhost:
/usr/local/nagios/libexec/check_nrpe -H localhost
I get the same error: Connection refused by host
I have installed Nagios Plugins and the check_nrpe plugin. I have edited the /etc/nrpe.cfg file:
allowed_hosts=127.0.0.1 ip_server
I don't exactly know if it is remote host's fault, monitoring host's fault or both.

I have a machine running with slackware64 13.1 and vnc servers is installed on it. It worked for months until yesterday, when I couldnt connect to the machine remotely.
I have 2 vnc "users" on this machine, root and "user". Each have their own desktop. Root has desktop :1 and user had desktop :2. Simple enough.
VNC servers is started via /etc/rc.d/rc.local with the command:
Code:
Code:
It worked flawlessly. I use the very same configuration on my home server, never had a glitch.
From the "distant" machine, I get this error when I try to connect:
Code:
Unable to connect to VNC server
What has changed so it no longer works? I assume its not a network problem since the machines are all located in my home network and there is no firewall or router in between them.

Is it fair to say that connLimit and hashlimit are very similiar on Linux i.e. while hashlimit caters to limits for groups of ports, they both set the connection rate limit per host? How in IPTables, do I configure a policy that limits connections on a port that encapsulates the total sum of all connections from all hosts? i.e. I do not want to allow more than 6000conn/minute for port range that is the sum of all connecting hosts?
