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 :)

Back to LinkedIn

Some time ago I used to have LinkedIn account which I have later deleted (don’t ask me why). Yesterday I recreated it and this time it will stay there :), so if you are there as well, feel free to get in touch (http://www.linkedin.com/in/alexmamchenkov/).

Everything is Miscellaneous

Jul 1st, 2007 | General, Google, Movies, Personal, Web Services | No Comments

There is a very nice talk on Google Tech Tacks named Everything is Miscellaneous where the speaker discusses problems with data organization/categorization. I am not going to cover anything from the speech here since it is better to see it. Myself I found it very relevant to a lot of problems people face everywhere like, for instance, categorizing/tagging blog posts, bookmarks, files/directories in on a file system or mailbox folders. Watch it :)

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.

Site modifications

Here we go, some more modifications on this blog:

1.  It seems that I have finally found a nice theme: Lorem Ipsum v1.2.7 by Brajeshwar which I have modified here and there to match me (including the addition of the top widget where I have placed a flickr badge, adjusting the CSS and some more).
2. I have started writting an About Me page which I hope will become somehow more consistent and full in a time. I am also planning for some additional pages later on (hopefully).
3. As I have mentioned in point 1, I have created a widget for displaying the badge from my flickr page.
4. The links (including blogroll and others) were recategorized. I have also added/removed some and I am planning to create a full blogroll page later on where I will place the whole bunch of links I am reading and watching on a daily basis.

I think that more changes will be comming from time to time. Meanwhile, if you see any bugs/mistypes/misbihaviours, please fill free to let me know so I can review and correct em all.
