Debian :: SSH AllowGroups Specific To Port Number?

Sep 17, 2010

Is it possible to setup SSH Daemon to listen on multiple ports and only accept specific groups to a given port? In the past I've created a second SSH Daemon by copying the config file and /etc/init.d/ daemon then configuring each port separately / rules however if I was able to maintain just the one Daemon that would be optimal. Is this possible?

Server :: Rewrite / Redirect Directory To Port Number In Apache?

Jun 4, 2011

I have a website example.com, serving pages on port 80. I want the url example.com/redmine to be rewritten to port 3000, where my redmine server is running, without actually changing the URL. So the user typing in example.com/redmine/test would serve up example.com:3000/test, without the user actually connecting through the port. I know this can work through CPanel, but I don't know exactly how it was implemented. I'm looked at how mod_proxy, mod_proxy_html, and mod_rewrite,

Ubuntu :: Port Forwarding Crutch - Number Of Apps That Are Unable To Have The Outgoing Port Changed ?

Mar 28, 2010

I'm not that great with mailservers, and just been thrown a curveball with a MS Exchange environment for which there is apparently no solution... yeah, right. But is there a workaround?

The problem is that the site mail (SMTP) needs to be sent via port 26 instead of the commonly used 25. Port 25 is mapped to a mailfilter, which apparently causes havoc with some of the mail, and the techs that have been on site trying to coax the Exchange server to co-operate have said that the only way would be to get rid of the filter.

The problem is that there are number of apps that are unable to have the outgoing port changed and so keep sending mail out on port 25.

I look after the Unix/Linux side of things at work, and I was wondering if there was an easy way to set up a Ubuntu box to receive mail on port 25 and just forward it to the MS box on port 26? So, in other words (and I hope this makes sense): monitor port 25, and forward whatever comes in on port 25 to the server on port 26. Simple portforwarding, or is it? What steps do I need to take?

Security :: Iptables - Limit Access To Port 8443 On Server To 2 Specific IP Addresses

Dec 23, 2010

I'm trying to limit access to port 8443 on our server to 2 specific IP addresses. For some reason, access is still being allowed even though I drop all packets that aren't from the named IP addresses. The default policy is ACCEPT on the INPUT chain and this is how we want to keep it for various reasons I wont get into here. Here's the output from iptables -vnL

[Code]...

Note the actual IP we are using is masked here with 123.123.123.123. Until I can get everything working properly, we're only allowing access from 1 IP instead of 2. We can add the other one once it all works right. I haven't worked with iptables very much. So I'm quite confused about why packets matching the DROP criteria are still being allowed.

General :: Changing The SSH Port Number?

Jan 12, 2011

im using CentOS 5.2 and cant change my default ssh port number. I have edited /etc/ssh/sshd_config to this

Code:

#$OpenBSD: ssh_config,v 1.21 2005/12/06 22:38:27 reyk Exp $
# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files

[code]....

I have then restarted ssh by typing (as root) "sbin/service sshd restart" and it restarts fine but still is on 22 and not 222.

Networking :: Ifconfig Address With A Port Number?

Sep 24, 2010

I'm trying to grok a problem I'm having with an embedded machine. I'm pretty sure I can track down the larger problem, but I came across a usage of ifconfig that I don't understand, and I'm pretty sure this is the command that is failing.

The command is: ifconfig eth0 192.168.78.20:9134

I understand how ifconfig works. What I don't understand is the :9134. I can't see anything in the docs about what this means. I know in most contexts it's a port number, but what does it do when bringing up a network interface? Does it limit it to only using port 9134?

Networking :: Ip Routing Based On Port Number?

Sep 30, 2010

I have 3 gateways in my office. I want to redirect all web traffic (port 80 and 443) through one gateway and ssh connections through other one. All machines have single network interface. For this what I did is created an ip alias et0:1 and assigned ip to it. Then wrote an ip route rule to route packets from eth0:1's ip to other gateway. All other traffic will go through default gateway. But here I am not sure how I can make web browser to use eth0:1's ip. It's using eth0 's ip. I wrote a ip table rule to change source ip of http packets to et0:1's ip. But rule is on POSTROUTING chain. So I think it's happening after routing.

Elementary... Here's the tricky part: next i have to handle user level ack the server is sending to "client"... To do that i have to open server socket on the same port number the system assigned to my client socket before. How can i get it ( in user level code)?

Server :: Sendmail: Block Specific Sender To Specific Recipient?

Oct 1, 2009

I'm trying to configure our mail server to block email from a specific sender reaching a specific recipient. In other words, if one of our employees is getting harassed by a 'stalker', how would one go about blocking, at the MTA (Sendmail) level, a specific sender email address from reaching a particular users inbox? We do not want to capture the email - simply block it before it consumes server resources.The Sendmail server (MTA) is a front end to our Exchange server so no user accounts exist on the Linux server. We simply use it as a SPAM and Virus scanner then forward clean email to the Exchange server.

ssh: connect to host servername port 30000: Connection refused

What am I doing wrong? I've also tried completely restarting the computer.

Networking :: Router - How To Find Port Number For Web Management

Aug 1, 2010

I enabled D-Link (DSL-502T) router web management (I am aware of security implication). I was able remotely to login to the router (by typing http://23.45.xx.6y) before changing the default number 80. Then I changed the port number from the default value 80 to 21908 (https option is not available) for better security, and when I tried to login to the router by typing this :

http://23.45.xx.6y:21908

Yes I am aware that if I am physically near to the router then I can check that , but this is not the case with me. How can I make sure that I had changed port number form 80 to 21908? Does NMAP do a trick to reveal which port is used for web management ? or are there other better options?

Ubuntu Security :: Cannot Connect To Port Number / When Firewall Is Enabled

Sep 5, 2010

i am using 9.10 karmic. Firewall is enabled. added ports with ufw allow [portnumber], and i still cannot connect to a port number. iv tryed ufw allow ssh/tcp but that does not work. the ports work when i disable the firewall and i dont want to do that.

ufw is available in all new installations of Ubuntu since 8.04 LTS, but is disabled by default. The standard Ubuntu installation has a no open service ports policy, so enabling the firewall by default doesn't gain any extra security in the default installation, but could provide confusion for people new to Ubuntu when new software that is installed does not work because of restrictive firewall rules. As a result, when first adding ufw to Ubuntu it was decided that users must 'opt-in' to using the firewall. In Ubuntu 9.04 and later, you can enable ufw during installation using preseeding. See /usr/share/doc/ufw/README.Debian for details.
