Microemulator and Opera Mini

Using the latest OpenJDK with Microemulator and Opera Mini proves, that internet browsing is possible. 

"Yes", "No" keys are accomplished by F1, F2

Classpath + JamVM chain has been tested too. But isn't advisable.

BSD-kernel for MIPS

Ola-la. Trying to figure out what's wrong.

Why my Yeeloong has disappeared from network?

Doing remote things lately with Yeeloong, I was puzzled why it lost SSH link. Looking at a router side, it gave me exact time when it all happened:

Jun 3 07:56:08 m-gw kernel: rl1: link state changed to UP
Jun 3 09:56:57 m-gw kernel: rl1: link state changed to DOWN

This is funny, I simply forgot to plug power cord. 2 hours non-stop on batteries :-)

Arora ... now even faster with QT4.5 and latest WebKit

Compiling Arora 0.7 against QT4.5 gives the following, better results:

ACID3, passed almost. You do remember previous result, don't you?

Sunspider test - almost 10x faster, comparing to the same result with QT4.4

And pentestmonkey JS-test

MD5 Benchmark took 3.927 seconds for 3000 hashes (764 hashes/second)
MD4 Benchmark took 2.786 seconds for 2700 hashes (969 hashes/second)
SHA1 Benchmark took 3.243 seconds for 1900 hashes (586 hashes/second)

Wonderful!

P.S. Thanks for a QT4.5/WebKit hint to Benjamin Meyer.

iPod touch (generation 2) and copying files via USB-cable under Linux

Those of you, who do own latest hardware from Apple (iPhone and iPod touch) could notice, that the only way to synchronize, or transfer music is to use iTunes. Which is only provided for Windows and Mac operating systems. This is, no doubt, very uncomfortable, that's why I've made a jail-break in order to install SSH daemon.

The other tricky thing is how to copy files when there's no WiFi spots near you? I would recommend to install iTunnel [1] onto Yeeloong and use scp.

In order to install iTunnel, you'll need to compile libiphone and libplist libraries from sources found at page [2]. 

I've installed libiphone into /usr/local/libiphone-0.9.1 and added the following line into /etc/ld.so.conf.d/libc.conf:

/usr/local/libiphone-0.9.1/lib

Then, it is required to update dynamic libraries' list:

# ldconfig

After that, make sure, that LDFLAGS line in Makefile from itunnel sources looks like that:

LDFLAGS := -L/usr/local/lib -L/usr/local/libiphone-0.9.1/lib -lpthread -lusb -lrt -liphone

$ make 

And here is it, itunnel program which will help you to communicate with iPod touch or iPhone!

Next step, is to setup a connection at a localhost with port number 12022:

loongson@debian:~/src/itunnel/itunnel-0.0.5$ ./itunnel 12022
get_iPhone() success
- successfully got device
server waiting for ssh connection
server accepted connection, clientfd:5
client thread fd(5) running, server port 12022 , peer port 37565
tunnel now running.
SSH to localhost port 12022 to get to iPhone.
 (use ssh -D to create SOCKS tunnel.)
do Ctrl+C to quit the server (can take a few seconds).
client is still waiting for handshake.

You do plug in your iPod, so you can see the following lines:

yes, got syn+ack ; replying with ack.

Voila. You can login now:

loongson@debian:~$ ssh -l mobile 127.0.0.1 -p 12022 -C
mobile@127.0.0.1's password:
