As stated earlier, zentyal is a full fledged routing platform (a lot more actually), but that’s not my point. The point is that after setting it up some bits and pieces were out of place. From a quick review after installation, a newcomer will notice that there doesn’t exist some overview monitor about networking. Also there doesn’t exist a gui approach to setup a secure access-point, and not all dynamic dns providers are covered to use with zentyal. In this post I’ll describe all the necessary steps that I took to fix those problems.

Well since my previous post the internet had hiccups, the routing was segmented, the seven stages of hell was unleashed (since IDS, antivirus and actual filtering was dropped down) to my small home lan. it was high time to change pfsense distribution which had frustrated me in the past like no other. There were 2 alternatives: First install a bare gentoo system, configure it and let it fly. Most of the necessary (hostapd, ntpd, dnsmasq, squid, fail2ban) parts I already had experience on setting them up, but I didn’t had experience in other important parts like snort, and havp. Things could go messy, but nevertheless I moved to roll out this plan. While I was compiling for the router (a single core amd sempron 2800+ : Sempron 2800+ @ 2000 MHz with 256 KB L2, 333 MT/s FSB, 12x multiplier, 1.60 Vdd) using fully distcc and ccache to speed up everything, I started downloading the following distros to test them under a virtualbox instance. To be frank I knew , that, setting up a routing gentoo platform in old hardware would be an impeccable act of faith, to myself, the distribution but foremost the hardware itself, but the reward would be a top-notch networking performance given the hardware.

as promised and within the 16hours deadline the kOlga is back online. The new feature set installation (hotspot, gardenwall, red queueing on all interfaces, etc) is postoponed for the future.
Enjoy the beautiful saturday and the weekend 
PS1. The tzikis link was decommissioned due to poor performance (4mbps up 4mbps down) but may be brought back if noone else provides a link for him.
PS2. To the guy that broadcasts in southwest patra region with mac address : 00:0B:6B:09:F2:7E and hidden SSID @ 5180Mhz please contact me if you interested for a link. My scans indicate a very good signal from your side (-55dbi with SNR of 50db)
the wifi node due to maintenance is down and will be down for at least 16hours.
There will be installed new ap cards, new casing and some new cool features.
My apologies for the inconvenience
Cheers
After a while trying establishing a new link among korki[1] and hawk[2], today the seed was grown. Since some rearrangement took place over tzikis roof (this guy had the worst cable management and efficiency I’ve seen ever) The link is pretty solid in at tzikis part. I have to align better but the results are quite cool for a first connection and given that his part isn’t at full height while mine isn’t the best alignment (-79 ~ -82 dbi)
OSPF and other thingies are setup and the only important thing is for tzikis to provide for some service and to organize his local lan (his subnetting skills are … 
)
Please welcome 10.140.31.0/24 to the network and with him the Panoulix (welcome back dude)
Cheers
Kolga despite the wikipedia definition [1] is something existing in this world(earth).
It is a wireless node located in the city of Patras [2] [3] participating in the public/open/free wireless metropolitan network named PWMN. It’s exact position is in the eastern part of the Olga’s square [4]. It’s operator and maintainer is the writer of this article (and generally of this blog) and his details are here.
The node’s name was originally selected because of the asteroid, but since then most people of this world are interested in the node.Writer’s guess is that the node should have 6 or 7 people interested in its operation, while the asteroid maybe has one or two intrested in its existance 
So dear visitors coming here from google bear in mind; that the node has no affiliation nor sponsorship from the asteroid.
Cheers!
After some rearrangements and link tune up the kolga-under link (operating on 5Ghz band) has stable throughput of 4,3Mbyte/s, which is kind cool since the rx power is at 3db fixed (while the max card capabilities are 17dbs).
So an eco-friendly link while maintaining its high throughput is as always an option and users should be encouraged to maintain such links.
Some real world application data transfers will be demonstrated in this article in future (as an article update) as well as the necessary software tuneups (mikrotik) in order for such a boost to take place.
Announcement to all users.
The kolga node due to some upgrades is and will remain inactive today (all the links are or will be down as well as the Access Point). The services offered and the link status will be restored (hopefully) at the end of the day.
For any new Information streams or any other status update this post will be updated.
From the management…
Προσωρινά τα gentoo-aware services (gentoo rsync and http ftp distribution files) θα είναι down.
Η επαναλειτουργία αναμένεται να συμβεί το αργότερο την Δευτέρα (9/6/2008) το πρωί. Ωστόσο υπάρχει αρκετά μεγάλη πιθανότητα να μην εξαντληθεί αυτό το χρονικό διάστημα και να γυρίσουν πάλι οι υπηρεσίες online σήμερα το βράδυ (το νωρίτερο). Σε κάθε περίπτωση θα ενημερωνεται το παρόν για κάθε εξέλιξη (σαν comment (σχόλιο)).
Συγνώμη εκ των προτέρων για την όποια αναστάτωση προκαλεί η αναβάθμιση.
Ο κόμβος pwmn.net-kOlga προσφέρει σε φίλους/φίλες που επιθυμούν να συνδεθούν προσωρινά, στον κορμό του PWMN μέσω internet την δυνατότητα να χρησιμοποιήσουν την υπηρεσία του VPN (PPTP)που προσφέρει ο κόμβος. Η κάθε σύνδεση λαμβάνει dedicated 256kbps upload 128 kbps download (το bandwidth αυτό δίδεται από την dsl που εξυπηρετεί το σπίτι). Η ταχύτητα διασύνδεσης με τον κορμό του PWMN ανέρχεται στα 4 MByte/s οπότε το bottleneck που υπάρχει περίπτωση να αντιμέτωπίσετε θα οφείλεται αποκλειστικά στην dsl. Για πληροφορίες και για account παρακαλώ επικοινωνήστε μέσω του forum με προσωπικό μήνυμα.
Η σύνδεση γίνεται στο address korki.pwmn.net και τα user credential δίδονται από το forum. Κατά την λειτουργία κανείς περιορισμός δεν υφίσταται, ως προς το είδος της κίνησης που επιθυμεί να περάσει ο πελάτης [1] . Οι αποδιδόμενες διευθύνσεις από για το VPN είναι στο range 10.140.4.240/28. Επίσης προαιρετικά και μετά από συνεννόηση εκτός από συνδέσεις τύπου PPTP μπορεί να δίδονται συνδέσεις τύπου OpenVPN και IPsec (tunneled).
Στις ρυθμίσεις για το PPTP πρέπει υποχρεωτικά να είναι ενεργοποιημένη η επιλογή για 128bit encryption.
Another happy service by pwmn.net-kOlga.
[1] Προσοχή: όλη η κίνηση περνάει μέσα από το snort οπότε ύποπτες δραστηριότητες -όπως μπορεί να της θεωρήσει ή εφαρμογή- μπορεί να διακοπούν κατά το δοκούν του IDS.
