Done? Ok.

There is one public IP assigned to WAN interface of the router while FTP server (of course run by Linux as well) has IP something like 192.168.123.14 or 172.16.*.* or 10.*.*.*. Moreover you want to allow people to access your FTP from every corner of Internet… So, there are several ways how to apply this but let’s talk about how to achieve this by means of using port forwarding feature that is available in any router’s functions list.

So, let’s say we have the following configuration:

Internet <-> [a] router [b] <-> [c] FTP server

[a] is WAN interface with 212.213.214.215 (just an example) IP assigned to it, [b] is NIC with 192.168.0.1 and [c] is server’s interface with IP 192.168.0.2. All what we need is that users from Internet can access FTP server using 212.213.214.215 IP and default 21 TCP port.

One of the main problems is that passive mode of FTP service uses any port from range 1024 to 65535 so it’s not enough to forward 21/20 ports to FTP server and let the ball rolling. So, go to servers’ CLI and open configuration file of an FTP service. It would be vsftpd, proftpd whatever. Let’s say we have vsftpd so we have to add the following lines to /etc/vsftpd.conf:

pasv_min_port=12000
pasv_max_port=13000

When changes are saved restart vsftpd server.

Now access router’s CLI and type the following:

iptables -t nat -I PREROUTING -d 212.213.214.215 -p tcp -m tcp --dport 21 -j DNAT --to-destination 192.168.0.1
iptables -t nat -I PREROUTING -d 212.213.214.215 -p tcp -m tcp --dport 12000:13000 -j DNAT --to-destination 192.168.0.1

This will add netfilter port forwarding rules which will redirect traffic coming at routers’ public IP through 21 TCP port to FTP server and will properly handle passive FTP mode.

Wuala - it’s a finish.

By the way, how to see current settings?
A: There are several Linux utilities coming with almost any distribution including Debian, Ubuntu, Fedora, RedHat, Mandriva, Centos whatever. See details below.

ethtool

This is rather powerful utility can display and change settings of ethernet network interface card. You can easily disable/enable autonegotiation option for your NIC, also it’s possible to manually set up duplex mode, configure wake-on-lan options, set speed settings. Just look through full manual page for ethtool. Here are several ethtool usage examples:

ethtool eth0 - shows current NIC settings

Settings for eth0:
        Supported ports: [ TP MII ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
        Advertised auto-negotiation: No
        Speed: 10Mb/s
        Duplex: Half
        Port: MII
        PHYAD: 32
        Transceiver: internal
        Auto-negotiation: off
        Supports Wake-on: pumbg
        Wake-on: d
        Current message level: 0x00000007 (7)
        Link detected: yes

ethtool -s eth0 duplex half autoneg off - disables auto-negotiation, enables Half Duplex.
ethtool -s eth1 duplex full speed 1000 autoneg off - disables auto-negotiation, enables Falf Duplex and sets up Speed to 1000 Mb/s.

mii-tool

According to manual it allows to manipulate and see media-independent interface status. Let’s see examples:

bash-3.1# mii-tool eth0
eth0: negotiated 100baseTx-FD, link ok - shows 100 Mbps speed, Full Duplex, Auto-negotiation is on.
bash-3.1# mii-tool eth0 -F 10baseT-HD - enables 10 Mb/s Half Duplex connection.

How to scrollback in GNU Screen?

A: In GNU Screen press Ctrl + a + [ to enter Copy Mode, then scroll up/down using keys j or k. Below are some other navigation keys:

h -    Move the cursor left by one character
j -    Move the cursor down by one line
k -    Move the cursor up by one line
l -    Move the cursor right by one character
0 -    Move to the beginning of the current line
$ -    Move to the end of the current line.
G -    Moves to the specified line
       (defaults to the end of the buffer).
C-u -  Scrolls a half page up.
C-b -  Scrolls a full page up.
C-d -  Scrolls a half page down.
C-f -  Scrolls the full page down.

By the way, in order to define scrollback buffer size start screen with the following key (5000 lines in this example):

screen -h 5000

Quick info about GNU Screen utility: it is Unix tool that allows to run multiple applications in several “virtual” windows. It is very useful when you need, let’s say, to see hardware resources consumption caused by started application in different console etc. GNU screen is also good option to run applications remotely via ssh: just run application in screen and log off until it’s finished, then just “pick up” screen session and see how the application’s output.

Update: You can use activate copy mode of GNU Screen also by Ctrl + Esc that might be more useful than Ctrl + a + [ shortcut (thanks to Yu-Jie Lin for this tip).

It takes from 12 to 15 minutes to crack WPA encryption according to statements made by PacSec conference organizers where Erik will demonstrate the procedure.

PacSec 2008 Conference will be held on November 12/13, 2008, at Aoyama Diamond Hall in Tokyo, Japan. The presentation is planned as “Gone in 900 Seconds, Some Crypto Issues with WPA - Erik Tews”.

WPA (Wi-Fi Protected Area) is widely used to protect many corporate and personal wireless networks. This protocol implements IEEE 802.11i standard and is a successor of WEP algorithm which was cracked in 2001.

Princess Ruruna is stressed out. With the king and queen away, she has to manage the Kingdom of Kod’s humongous fruit-selling empire. Overseas departments, scads of inventory, conflicting prices, and so many customers! It’s all such a confusing mess. But a mysterious book and a helpful fairy promise to solve her organizational problems—with the practical magic of databases.

In The Manga Guide to Databases, Tico the fairy teaches the Princess how to simplify her data management. We follow along as they design a relational database, understand the entity-relationship model, perform basic database operations, and delve into more advanced topics. Once the Princess is familiar with transactions and basic SQL statements, she can keep her data timely and accurate for the entire kingdom. Finally, Tico explains ways to make the database more efficient and secure, and they discuss methods for concurrency and replication.

Examples and exercises (with answer keys) help you learn, and an appendix of frequently used SQL statements gives the tools you need to create and maintain full-featured databases.

By the way, does anybody know where to buy manga illustrated guide to MPLS (Multiprotocol Label Switching)?

  2. Apache 1.3.2 is released. Upgrade now!
  3. Microsoft questions Linux’s free model. Rich Gray, intellectual property attorney, thinks that the Linux model may not last.
  4. MCI WorldCom Exec On Linux: Not So Fast. Uunet has not yet decided whether to deploy Linux.
  5. Caldera announces partnership with Sybase.

    Caldera has made two announcements today: They will be shipping Sybase with their next release of OpenLinux, and OpenLinux 1.3 will be out on September 28th 1998.

  6. Interview: Linux creator Linus Torvalds (in Real Audio).

  1. Canonical Store is to sell multimedia codecs for Ubuntu. Codecs are developed by Fluendo and Cyberlink. It is still possible to do sudo apt-get install ubuntu-restricted-extras and get that staff installed…
  2. In A comparative look at compact sysadmin distributions article Cory Buford shares the observations he got during review of several portable (not more 210 Mb) Linux distros which may be helpful to handle “minor catastrophes”. BTW I prefer RIPLinuX :)
  3. T-Mobile, Google and HTC announce that first phone based on Android platform will be out next week (23th of September 2008).
  4. Google is going to launch its own “computer navy” (sea floating data centres). Now jokes - rumors.
  5. Codeweavers company has adapted Google Chrome browser for Linux and Mac platform.
  6. Mozilla asks to display firefox EULA in Ubuntu 8.10. Some people are really disturbed about that.
  7. XFCE 4.6 first alpha is out for public testing.

And we just launched Linux and Open Source News aggregator at Linux Screw, so you are welcome to set it your homepage ;)

This staff is already available for downloading as DEB packages for Ubuntu (32-bit and 64-bit), as RPM for RedHat, Fedora, CentOS etc. as well as self installable script for any other Linux distribution.

Well, after quick testings there are no doubts that it is not a good option if you wish to have quick and stable alternative for Firefox… But of course it is good for evaluation purposes or for those people who CAN’T wait for official release of Chrome for Linux :) Certainly the port is based on Windows copy run by Wine (don’t forget to upgrade it). Actually CodeWeavers says that this is just a proof of concept, for fun, and to showcase what Wine can do.

Sounds strangely? Just read below!

Computing centres are located on a ship or ships, anchored in a water body from which energy from natural motion of the water may be captured, and turned into electricity and/or pumping power for cooling pumps to carry heat away.

This text was somehow seen by The Times in this patent application written by Google… Rather interesting article is published at their site. As for me, I didn’t know that Microsoft is planning to build data centres in cold climes of Siberia or that Sun is going to place its supercomputers in abandoned coal (see cold) mine…

By the way all data centers around the world consumed about 1% of all electricity in 2005. How do you think, what would be in 2009? :)
