How can I forward all traffic from a public IP to another public IP. Let's say I have a first debian box named box1 with eth0 = 1.1.1.1 and eth0:1 = 1.1.1.2 and I want to forward all traffic from 1.1.1.2 to "box2" located somewhere else over the internet and having for eth0 2.2.2.2 Both 1.1.1.0/24 and 3.3.3.0/24 are public IP ranges.
View 1 RepliesI installed Chromium Browser and made it default. The version which is available through squeeze and wheezy main is a dinosaur, and as such I cannot install any Chrome addons. I tried ubuntu or launchpad ppa for Chromium-Daily. I added [URL] maverick main to my Third party Repositories. Its not working.
The terminal returns an error:

I'm trying to write a p2p file sharing program using python's built-in libraries. Everything is going well. The only thing is that i'd like to be able to use openssl public and private keys so only a host with the public key could access/decrypt the filesharing. I've gotten these libraries (httplib, basehttpserver, ssl, os) to work using just a pem file containing both the public and private keys but no success with them seperately. Can someone point me in the right direction or offer an alternative? PS, the goal of the project is to create an anonymous, decentralized, secure file sharing program. I want to be able to upload this to sourceforge so everyone can use it, if that's any incentive
View 2 Replies View RelatedI need to be able to do the following: Physical Router located at 192.168.40.1 On Ubuntu 10.04 Lucid machine:
eth0 with static ip 192.168.40.2
eth1 with static ip 192.168.40.3
eth2 with static ip 192.168.40.4
Associate a virtual address to eth1 with an entirely different network address such as 192.168.50.1 Do the same (virtual address) for eth2 -- e.g. 192.168.60.1 In the application:
register phone number A at 192.168.40.1 (The application will automatically use eth0 for this)
register phone number B at 192.168.50.1
register phone number C at 192.168.60.1
Somehow forward all traffic (including the register request) sent to 192.168.50.1 to 192.168.40.1 as if the register had been made directly to 192.168.40.1. In other words, the app "sends" registration and traffic to 192.168.50.1 but then Ubuntu forwards it to 192.168.40.1 (but the app does not know that). Similarly, forward all traffic sent to 192.168.60.1 to the router at 192.168.40.1.
Do the same for the reverse, forward all traffic that the router sends back to 192.168.40.3 (eth1) to 192.168.50.1 (within the Ubuntu machine) so that the app knows it is for phone B. Similarly forward all traffic that the router sends back to 192.168.40.4 (eth2) to 192.168.60.1 so that the app knows it is for phone C. Thus, the application believes that it is registering at 3 completely separate routers on 3 completely separate networks via 3 separate network interfaces but in fact is really registering all three to the same router (but does not know that). Similarly, the router believes that it is receiving 3 separate registrations because it receives each registration request and traffic from 3 separate interfaces and thus 3 separate mac addresses (i.e., of eth0, eth1, and eth2). Traffic sent to and from the router for each of the 3 phone numbers (via eth0, eth1, and eth2) are not mixed because the translation happens in both directions.
I run the following file with the >log.log redirector and it does not capture errors.
#!/bin/bash
echo ************************BEGIN LOG******************************
date +"%m/%d/%Y %H:%M:%S $HOSTNAME"
cp -f /scripts/original/clamscans.log /scripts
[code]....
The following errors show up when I run from the file from the term window, but are not written to log.log:
tar: /public/public/clamscans/*.txt: Cannot stat: No such file or directory
tar: Error exit delayed from previous errors
mv: cannot stat `/public/public/clamscans/*.txt': No such file or directory
I know with windows you can add the 2>&1 to capture error data. Is there such a thing for Linux?
iptables and multiple public-facing IP addresses. With the current setup I have a public-facing firewall with iptables which will then forward traffic to a LAN IP. I will hopefully be allotted 1 private IP per public IP, which I hope will make this much more simple. For example, I have server A with the LAN IP of 10.0.0.1 which I would like to have traffic forwarded from 5.0.0.1, the public IP. I also have server B with LAN IP of 10.0.0.2 which I would like to have forwarded from 5.0.0.2, the second public IP. From what I have read and understood, this should be a simple task, however I would just like to double check to make sure that it is in fact possible, and if so, how would it be recommended that I go about doing so. Essentially, I need to forward each public IP to a corresponding LAN IP with all ports.
View 3 Replies View RelatedI've installed it properly until it works now, it does send emails and receive them, but heres the problem.
1) it does not send emails to a certain domain, unless i do dpkg-reconfigure on exim4 and put the domain on allowed relay... can't i just put something on settings which allow to send emails to ALL domains?
2) EVERYONE can connect to the server by telnet from any position, terminal or pc, and just use an existing user to send emails to anyone.... example, i have testuser123 setted up in debian/exim4 .. then they simply write "mail from:testuser123@host.dot" and the server accepts it.. without even request an authentication for that. And this is a problem, because everyone can use my email addresses to send emails to whoever.. heaven for spammers/hackers..
In one of my customers, the new internet connection have no public IPV4(using GCNAT), only public IPV6.
And there are various services that require external access, like, vpn (openvpn), a java/web system, ssh, rdp(windows).
fileServer(by vpn).
All is running ok in IPV4.Maybe, the solution is a NAT 6to4. We know this is the future, no more public IPV4.

My ethernet controller is configured as such:
My /etc/resolv.conf file is normally just set up to use Google's public DNS:
When I connect to the network at the university library, it totally overwrites my /etc/resolv.conf file to something like:
This is pretty annoying, so I tried comprimising by making a file with the school's domain and search entries plus the Google nameservers, then revoking write permission on the file. However, I couldn't access any domain name with this config on their network, so I reverted to using their nameservers. I keep all the school's entries commented out when I connect to my home network.
My ultimate question is what is actually overwriting the file? I suspect that my connecting through DHCP is responsible. Whatever it is, I'm pretty annoyed that no back up file was created.

View 4 Replies View RelatedI often run into this and it's such a hassle that I have had no choice but to ignore it. But, I would like to run it properly but I don't understand why my sources list is 'wrong' or has incorrect info so that it's often not verified or authenticated. The public keyring is wrong or the source or both? I get these messages, for e.g.:

I'm pretty new to Debian, and I'm trying to set up Apache 2, and I want to set the DocumentRoot to public_html in my home dir, but I run into some problems.
I tried to change this (/etc/apache2/sites-available/default):
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/
<Directory />
Options FollowSymLinks
AllowOverride None .....
When I restart apache I get a 403 error, and when I change it back to its original, it works fine. I want to change the DocumentRoot so I can upload files via FTP to ~/public_html.
~/public_html has the mode 777.
