Ubuntu :: Create A Reverse SSH Proxy For A Telnet Process
Mar 12, 2010I have a project that I'm working on now that is using Ubuntu 8.04LTS to create a reverse SSH proxy for a telnet process. We have the box logging in with RSA keys so that it can automatically connect to the SSH host on our end. We are using autossh to keep the connection up and running.
We have rolled out 3 of these and they are working very well. We ghosted the original, changed the hostname, changed the IP info, and regenerated the SSH keys. Now I need to clone 35 more. I want to try to do this as efficiently as possible and can script the changes in the hostname, IP, ect.
Can I batch create RSA keypairs on my workstation and then copy them over as a part of the batch? My current other option is to login to each of them and generate the pair. I would like to just install the drive and ship it and not even have to boot it up.
General :: Create Tunnel To Utilize For Telnet Connection?
Nov 8, 2010Machine A is located behind client firewall. The machine runs telnetd. This is Linux machine with Python 2.5.4 installed. I do not know the IP addy of the router and firewall is not open incoming. outgoing firewall is open.
Machine B (Windows machine) is a server with well known IP address. I can install any programs I want on either machine.
The idea is that I want Machine A to open a socket to machine B. Then I want to hold that socket and use to run a telnet session from Machine B to Machine A telnetd server.

Apr 18, 2011I've configured postfix on my linux server. For the most part, I got everything working (IMAP, apache, etc) but for some reason, I can't get postfix to work remotely. Postfix works locally to send mail. E.g. when I telnet locally to port 25. However, when I try to telnet from outside, the connection closes almost immediately. I've looked at various configuration options and tuning enhancements but found nothing helpful. Here is my config:
Code:
main.cf:
#See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default

Server :: Cannot Telnet To 25 But Can Do It To 22
Nov 9, 2010I just setup a server using Ubuntu 10.04LTS Desktop edition. I am a novice in these things. I was able to setup the SSH server and it works from outside my LAN quite well. I can telnet to it also with 22. I have then setup an email server. I can do telnet to it from the server itself but from the internet it just times out.
I did netstat -nlp and it shows that it is listening to port 25. I have port forwarding for 25 enabled on the router. I cleaned up all the rules of iptables and iptables -L shows everything is accepted.

Server :: Telnet To Port 25 Not Working From Outside?
Mar 25, 2011I'm trying to test smtp connectivity to my postfix configuration and I can telnet to port 25 from the computer itself but cannot from the outside. I get a connection refused error message. What am I doing wrong? I believe my dns is setup correctly as it seems the telnet can hit the box so I'm fairly sure its not that.

Server :: Sendmail: Telnet Test From External Networks
Jul 22, 2010I seem to having some strange issues with my new sendmail server and was hoping that somebody can offer some assistance with this issue. I recently tried to setup an enviromental monitor that sends alerts via email using a dedicated email account I created on my sendmail server. For whatever reason, it does not seem to be able to send emails, and I have verified the account credentials multiple times.
So I attempted to run a telnet SMTP test to determine what the problem was. I was able to connect and send the emails using this test perfectly fine from my local subnet, however I ran into problems attempting this test from the outside world. When I connect the SMTP PORT 25 from the outside world, I get what seems to be a malformed SMTP greeting.
