Ericsson p910, Linux, Mobical

Jan 7th, 2008 | Hardware, Linux, Networking, OS, Personal, Software, Symbian, Technology, Web Services | 1 Comment

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 :)

Transport Tycoon Delux data files

Jul 17th, 2007 | Blogging, General, Software, Technology | 44 Comments

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.

IDE vs Text Editor for Web

Jul 9th, 2007 | Personal, Programming, Software, Technology | 2 Comments

I see more and more people are starting to do web programming (including HTML, JavaScript, PHP/Perl) in kind of IDEs like Dreamwaver, Frontpage, Nvu and so on. It looks a bit weired for me. First of all coding in proper text editor (like Vim) gives you all kinds of features like text highlighting, tags auto completion, multi-file editing and so on. Second, while writing your code directly in editor you specify proper names of styles/classes/whatever from the beginning instead of your IDE assigning some stupid names like style1, id15 and similar and than you going over to correct them (or sometimes navigating through 100 GUI menus to change them or even leaving them like that). Third, you can write all-browsers-compatible code from the start instead of dropping elements here/there which will perfectly work in let’s say Internet Explorer and then trying understand what code was generated by IDE and adjust it. Finally, coding with text editors makes you think more and thus make better code then just letting things go as they done automatically and then correct a bunch of problems and not taking into consideration other bunch of problems because your IDE couldn’t do it well and you haven’t thought about it since you even haven’t seen the code.

Firefox Universal Uploader

Jun 24th, 2007 | Flickr, Software, Technology, Web Services | No Comments

Found a very nice Firefox extension for uploading files to flickr and youtube: Firefox Universal Uploader. It provides some nice features like more filemanager like interface for mentioned services, as well as shows the progress of uploads and so on. Finally it allows me to manage files on flickr and youtube from within Firefox without installing some additional standalone software.
