Finally I got my p910 back from the repairs (had problems with screen). Playing around with it during weekends (oh yes - I was missing it a lot) and I have managed to sync my contacts from p910 via bluetooth and my laptop running fedora 8 to mobical. This was more than critical for me after I didn’t have access to my phone contacts for few months.
The major problem for me was to make p910 utilize internet of my laptop through bluetooth. There are a lot of how-tos, but all of them were missing smthing :(. Here how it worked for me (originally found here):
Put the following into /etc/ppp/peers/dun
460800
debug
ipcp-accept-remote
192.168.1.1:192.168.1.2
MS-DNS <IP of DNS server used by linux box>
lock
crtscts
noauth
defaultroute
Then put this to /etc/sysconfig/iptables:
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:RH-Firewall-1-INPUT - [0:0]
-A INPUT -j RH-Firewall-1-INPUT
-A FORWARD -j RH-Firewall-1-INPUT
-A RH-Firewall-1-INPUT -i lo -j ACCEPT
-A RH-Firewall-1-INPUT -i ppp0 -j ACCEPT
-A RH-Firewall-1-INPUT -p icmp –icmp-type any -j ACCEPT
-A RH-Firewall-1-INPUT -p 50 -j ACCEPT
-A RH-Firewall-1-INPUT -p 51 -j ACCEPT
-A RH-Firewall-1-INPUT -p UDP –dport 5353 -d 224.0.0.251 -j ACCEPT
-A RH-Firewall-1-INPUT -p UDP -m UDP –dport 631 -j ACCEPT
-A RH-Firewall-1-INPUT -m state –state ESTABLISHED,RELATED -j ACCEPT
-A RH-Firewall-1-INPUT -j REJECT –reject-with icmp-host-prohibited
COMMIT
*mangle
:PREROUTING ACCEPT [0:0]
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
-A PREROUTING -i ppp0 -j MARK –set-mark 0×9
COMMIT
*nat
:PREROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
-A POSTROUTING -m mark –mark 0×9 -j MASQUERADE
COMMIT
Then run the next set of commands (as root):
/sbin/service bluetooth start
/sbin/sysctl net.ipv4.conf.all.forwarding=1
/sbin/service iptables restart
dund –listen –encrypt call dun
Here we finished with Linux setup. Now get yourself a GnuBox application for p910. Follow the instructions on how to set it up on the GnuBox website. Finally, open gnubox, go to Options -> 2box Bluetooth -> LAN Access server, select your linux box in a list of devises, tell “Yes” when asked about encryption. Done, now you can use internet with “Bt” dialup account from your phone (refer to GnuBox setup instructions) and it will take you the whole path through linux to internet :)
The mobical part is easy - just register there and you will get an auto-configuration SMS for your p910. Now you can sync in any direction :)

Quite a while ago I wrote a post mentioning a problem with fonts when using RDP over FreeNX. Now it seems that the problem is fixed and everything works. I have reinstalled the freenx server on my FC5 server (the latest version available for fc5 from yum repos I have is 0.6.0) and also put a latest (3.1.0) nx client on my fedora 8 laptop. Things just work :) and they are really fast and easy.

I have noticed a post called “Two internet connections: how is better” I posted two years ago in the “This week last year” box on the right of my blog. That time I did two firewall and so on (as explained in the that post), but now everything has changed and I am glad.
First of all I got a server with 3 ethernet cards and put all the ends into it (two WANs and one LAN). Then I setup load balancer and line failover which works really great. All of the above was done with pfSense firewall (which I really love and have installed at many places, including three places I maintain, plus my computer supplier office as well as two offices of Kean factory). pfSense works just great and has a lot of functionality free of charge :)
Currently I have tested all basic things like DNS forwarder, DHCP, filtering and so on, plus IPSec (static-to-static, static-to-mobile_client), PPTP, Load Balancer, Traffic Shaper, Failover and ntop module.

We are currently in the process of migrating old unbranded 42U cabling-only (not deep) rack to new HP (10K series) one which have to contain old patch panels (9 of them) and other cabling stuff as well as 5 1U HP ProLiant DL360 servers. Very routine task but I really like it.
All patched panels were already transferred (with a bit of reorganization). Additional wire managers were installed. New power pallet units were added (very nice ones from HP for better power system). New servers are also mounted and so on, just have to finish minor stuff and I will post some pics :)
Two things pissed me off: 1 - HP now supplies screws (the ones to mount stuff in the rack) which need alien key (thanks God I had old normal screws I used), 2 - HP had changed the normal side panels (one per side) to some tricky 3-part-per-side panels. I took us some time to figure out how to set those parts up and it turned out to be not-that-comfortable to work with em.

I see a lot of hits for the Open Transport Tycoon Deluxe post which I made quite a long time ago and where I have mentioned the download of the full pack of OpenTTD with original data files. This download is not available from that server anymore (for some time already as well), but since I (still) have data files, here is an archive of a full data folder from OpenTTD, just get what is missing from there for your setup.
