IPAM (IP address management)
Lately I have played around in my free time with creating IPv4/v6 address management program, as a replacement for managing IP addresses and subnets etc. in excel file… There are many commercial IPAMs available, which can do even more stuff, but I prefer to keep things light, simple, free and without unneeded balast.
App is ajax-based using jQuery libraries, it uses php scripts and javascript and some HTML5 features, so some modern browser is preferred to be able to display javascript quickly/correctly…
Some main features include:
- Section / Subnet separation
- IPv4/v6 support
- Displays free range and number of clients
- Subnet statistics
- User management
- E-Mail notification
- Import IP addresses from XLS / CSV file
- IPv4/v6 calculator
- Search IP database
- and many others.
If there will be interest I plan to launch it as an open source project. Next plans for v 0.2 are use of domain authentication, viewer-only user type, rss change feed, mass edit/delete/create, etc.
App can be tested on the following demo page:
ipamdemo

mysql | sort by IP address
One small tip – if you have table of IP addresses and you want to sort them by IP addressing it will not work properly…:
mysql> select ipaddr from ipaddresses order by ipaddr asc; +---------------+ | ipaddr | +---------------+ | 10.12.50.1 | | 10.12.50.123 | | 10.12.50.2 | | 10.12.50.5 | +---------------+ 4 rows in set (0.00 sec) mysql>
As you can see the .123 should come last but it is in second place… The solution is to use mysql's aton function, which transforms IP into integer and sorts the fields properly…
mysql> select ipaddr from ipaddresses order by INET_ATON(ipaddr) ASC; +---------------+ | ipaddr | +---------------+ | 10.12.50.1 | | 10.12.50.2 | | 10.12.50.5 | | 10.12.50.123 | +---------------+ 4 rows in set (0.00 sec) mysql>
Apache IPv6 UMTS server @Nokia N900
Nokia N900 is the first mobile device that can do "dual-stack" IPv4 and IPv6 connection on packet data mobile networks (EDGE,UMTS,HSPA) – well, 2 separate PDP contexts anyway, but close enough since it is not really supported by 3GPP yet. It requires some kernel modifications, which I cannot provide here, but if there is any interest send me email and I can provide some info on that subject…
Anyway, once we have IPv6 connectivity to internet we can also setup device to act as web server – since it is a Linux device this is not too hard to do. However, most mobile operators block the incoming TCP connection toward clients to prevent overcharging, so contact your ISP to verify if incoming connections are allowed. Here is the output from my ifconfig, that shows two active mobile data interfaces and sessions, one for IPv4 and second for IPv6:
gprs0 Link encap:UNSPEC HWaddr *
inet addr:10.10.9.14 P-t-P:10.10.9.14 Mask:255.255.255.255

Genoo linux article
Dober clanek o Gentoo Linuxu:
http://kernelnews.com/articles/2010/gentoo_linux.html
Gentoo Linux provides one of the most highly configurable Operating Systems around. Although the time spent installing and configuring Gentoo can turn out to be days instead of hours, the final installation will be totally optimized and customized to how you use your computer.
Zadnje case opazam, da je veliko manj tezav pri nadgradnji paketov…

Captcha with jQuery, ajax and php
A while ago I came across this guide, as I was searching for some simple captcha implementation for some website. Plain and simple, all clear. The only thing I didn't like too much is the javascript part, for webpages I mainly use jQuery for javascripting, so I wanted to use jquery for ajax functions. Also, including multiple inputs besides captcha code makes javscript more comeplex (please read the comments, near the end) nad that is where jquery comes in handy.
The simplest possible example you can find on http://mihap.si/share/captcha/.
What we need:
IPv6 proxy streznik | squid 3.1
Squid od verzije 3.1 (trenutno je se v beta verziji) naprej pozna IPv6 protokol in zna delati kot ipv6 proxy streznik… To je med drugim uporabno tudi na mobilnem podrocju – vecina mobilnih naprav se nima dual-stack podpore (oz ipv6 podpore), ce smo natancni, mislim da v casu pisanja samo Nokia Symbian telefoni podpirajo IPv6 dialup preko EDGE/HSPA omrezja. Tak proxy postane uporaben v primeru, da imamo na voljo samo IPv6 povezavo, rabimo pa tudi dostop do IPv4 streznikov.
Do squida dostopamo preko IPv6, ta pa nam poleg IPv6 servira tudi IPv4 sajte -> v kolikor dobi od DNSa oba A in AAAA record jasno uporabi IPv6 povezavo… Vec o IPv6 podpori v lignju si lahko preberete na tem linku…
Same instalacije se nebi dotikal, kot vedno je odvisna od platforme… V kolikor nalagate binarne pakete bi morali imeti ipv6 podporo po defaultu omogoceno, v nasprotnem primeru ne pozabite sestaviti squida s podporo za ipv6.
Nastaviti moramo sledece:
- IPv6 nastavitev dostopovne tocke (APN) na telefonu ali
- Nastavitev brskalnika, da uporablja proxy streznik (google it!)
- IPv6 konfiguracija streznika
Is my GPRS/UMTS modem ipv6 capable?
Here is how you can check if your modem is capable of doing an ipv6 dialup… I won't get into details about how to connect to device via terminal, i wrote something similar in this post.. (Hint: M$ hyperterminal or putty, Linux and OsX minicom)
Once you are logged onto device you have to issue following command, with which you see the supported connection types: at+cgdcont=?. Here is the output from my Novatel mc990D card:
at+cgdcont=? +CGDCONT: (1-16),"IP",,,(0-2),(0-3) +CGDCONT: (1-16),"PPP",,,(0-2),(0-3) +CGDCONT: (1-16),"IPV6",,,(0-2),(0-3)
If you see a third line (yes, the ipv6 one) then you are good to go.
