when i try a telnet to a host like that: telnet 10.10.10.10 1234 i got this: telnet: Unable to connect to remote host: Connection refused.
1/ does this mean that the problem is not due to a firewall, but that the host 10.10.10.10 doesn't listen on the port 1234? other way does this mean that my firewall is authorizing traffic on the port 1234?
and when i try a telnet on another port like that: telnet 10.10.10.10 1235 i get: Trying 10.10.10.10 ...
in this case this
2/ does this mean that the firewall is blocking the traffic between my host and the 10.10.10.10 on the port 1235?
I did a clean install of the latest version of Ubuntu. For some reason, there are still internet-issues. When I tried out the following command
Code:
telnet
open ftp.microsoft.com 21
I got
Code:
telnet: Unable to connect to remote host: Connection timed out
Also, during install of the new ubuntu, it was unable to reach the repos for downloading. Odd thing is that I can go online, and that when I type 'ftp.microsoft.com' in my browser, it displays the file-hierarchy.

View 3 Replies View RelatedI'm trying to make an SSH script for my place of employment. This script, I want to go out to the server hostnames we have specified (in another file) and change a users account password. We use Kerberized telnet, so if telnet root hostname fails, I want it to use ssh username hostname and use the old password (specified). If both fail, I want it to ask the user what the port should be and input the port in the ssh command.
But I'm having a issue having it try telnet root hostname and if it fails then, try to ssh in, I have no clue how to have it proceed. Is it an if statement? Here's the telnet failed message: telnet: Unable to connect to remote host: Connection refused

The ip address of the vncserver is correct because i can do ssh on it. Where or what can i do?
I have a box (boell) running Fedora 10 sitting behind a firewall at school. I am able to freely ssh to and from this box to other computers (minion) within that lan. Outside of this network I cannot directly ssh to boell - I must ssh first to minion, then I can ssh to boell. I've spoken with the sysadmin and he's verified that the firewall permits ssh freely - i haven't had any issues like this with other boxes of mine there, so this isn't any surprise.
I have verified that the hosts.deny file is blank, iptables permits ports 22 (and 80) and I didn't see anything obvious in the sshd_config. I tried a tcp dump on the external host and boell while attempting to ssh from the former to boell. The packets appear to be acknowledged by boell, but this fails to lead to a connection. I've tried this process with external hosts in different locations with the same result. I have made few modifications to the default installation for F10, so perhaps there is some default somewhere I have to change. In any case, below I have attached excerpts of germane files.

View 1 Replies View RelatedWe recently had a vulnerability scan done on our network and one of the vulnerabilities was that the dns server discloses the remote host name when using hostname.bind.

Is this possible that a process running on a remote-host only inform nagios when some thing is wrong. Rather then nagios-monitoring-server checking through NRPE every so often. Reason is I want to add too many alerts in the application. And I don't want a whole list of ok messages.
View 1 Replies View RelatedI've set up a server running Ubuntu 10.10 (desktop) with apache. Problem is: When I try to configure multiple virtual hosts I can only access the first one. I'm sure that I'm missing something basic in my setup, but I cannot seem to figure out what.
What I want is simply two virtual hosts, one only available on the LAN where I can test my php files and one "live" available from the outside.
Heres what I've done:
Installed Apache2.2
Copy /etc/apache2/sites-available/default -> /etc/apache2/sites-available/dev
Modified "dev" config DocumentRoot and Document to point to /var/www/dev
Modified "dev" config VirtualHost to <VirtualHost *:1337> (port change right?)
Modified "default" config DocumentRoot and Document to point to /var/www/live
[Code].....
Live works fine, but dev cannot connect (as if there is no server there).

View 5 Replies View RelatedI installed Ubuntu 9.10 on a friends computer when Windows died on it, and though she has had relatively few problems with it, she still occasionally has problems that are really hard to impossible to fix over the phone. She is also not very knowledgeable with computers, so I was trying to guide her through setting up so I could connect to her remotely and try to figure things out, but I cannot get it to work.
I personally don't use Ubuntu on my computer, I use openSUSE and KDE so that does add to the problem, though I have used Ubuntu and Gnome a lot in the past.
I had her go to remote desktop settings and allow connections from other computers and allow other users to control the desktop, and at first I had her require confirmation and a password but it didn't work without it either. When I try to connect, it just hangs for a while then times out. I tried using KRDC and just VNC in the terminal with the same result.
There should be nothing on my side preventing a connection, but I am not positive. I am not very familiar with remote desktop outside of a LAN either. I am just trying to connect using her IP address, I don't know if there is anything else I need to include. Is there maybe some other setting that needs to be changed or maybe her DSL modem/router is blocking me though I don't know why it would, especially since P2P programs work fine.
