Bellow picture is registration info page.

(The picture is deleted.Above page is refreshed to tutorial site.)

You can swich to another user.
You need to know user name and user password.

ID exists Your windows registry.(find c2bf.exe in registry)

I heard some people wondered Team2ch are rising in Ranking quickly.
Personal c2bf clients swich to Team2ch by moving.

Do you want to go out frozen-layer?

This sentence is transration from http://www.marumo.ne.jp/db2004_2.htm
His diary includes privately.

feb. 6 fry AVHDD crack [41]
I am a programer reside in custmer,
I am working in the daytime for buying new server and internet provider fee,unfotunately.
I am programing encorder of H.264.(See Notice #1)
I makes it more faster,more richly picture quality,everyday.

I implemented algorythm by C language,and charenged programing software faster by SIMD.(#2)
If result is slow/poor,I try to use another algorythm.
I repeat that operations,every week.
I am tired.

By the way,MOGI,Kazuhiro works in Tohoku university.(#3)
He is NOT me.
***
I started installing softwares to new server.
New server needs many sofrwares compare with dafult installed.
I may be spend time finishing install.
Later on,I must check the new server running keeps good by my private computers.
Ready for starting new server till feb 8 24:00JST (15:00 GMT),
The time is not sure,sorry.

The plan moving into new server is;
1.Copy data from old server to new server.
2.Change DNS entry "www.marumo.ne.jp".(TTL setting as 3600 sec.)
3.DNS cache become invalid from clients access,the moment clients access new server automatically.

While exiting DNS cache,analysys report is in vain from client.
This plan is needless to restart c2bf clients.
If you noticed bugs in whole plan,e-mail me.

If many clients exit c2bf client,Moving is smooth.
I will announce the time on "http://www.marumo.ne...bf/status.html",
and decide the time till tomorrow at 16:00 JST (07:00 GMT).

####
Notice
#1,"H.264" is MPEG-4 encorder.
#2,"SIMD" kind of processing (ex.MMX)
#3,"Tohoku university" is in Japan.
(These are no business on c2bf project.)
####
7 feb sat AVHDD crack [42]
Now (11:40 JST / 02:40 GMT), it comes to the stage which MARUMO makes his PC a client and can do the test of the new server.
If it seems that no problem occurs especially with it, the server shift is likely to be made to 24:00 JST (13:00 GMT) of .
***
I decided to swich to a new server at feb 8 24:00(JST)
The shift schedule is;
feb 8 22:00 Change TTL configuration of DNS as 10 minutes.
feb 8 23:55 Take a back up from an old server,and copy to a new server.
feb 8 24:00 Registter IP adress "www.marumo.ne.jp" as a new server.
feb 8 01:30 Till 01:30,I am cautious of accident.

If possible, please stop your client software for 20 minutes from 14:50 GMT to 15:10 GMT.
I tuned the server loses minimum analysysed blocks from cliient computers,Even if you do not stopping client software.

I hope to run the server keeps stability,and clear off anxious factors.
Shall you corpolate me?(Onegai simasu)
***
I do not guess you misunderstand,the X day is NOT tonight.
Are you OK?

I wanted plenty time to inform you that.(more than 24 hours)
In fact,I do not finished testing the server works completely.:-P

###
A Diary in 7 feb is all.
Which do you feel better babelfish transrations than mine?
I have a liitle confidence.Did I improved?Point out my mistakes.
###
Infomation from Marumo,http://www.marumo.ne.jp/

Feb 7: I decided on the shift time of a server as 15:00 GMT on February 8. If possible, please stop your client software for 20 minutes from 14:50 GMT to 15:10 GMT.

Sorry for broken English.

buenos dias
Please use a Japanese font to read below.
I take a rest today.

I tryed to read a web site written in Japanese transrated to English by babelfish.
Some words were not transrated,Some words had wrong meaning.

I wrote memo for your reference.

鯖,サバ,mackerel-->server
round, roundly-->MARUMO=webmaster
Mogi Japan and europe-->MOGI kazuhiro=MARUMO=webmaster
Quaintness->good
shelf-->means affirmation
スレ-->a minimum unit of BBS in "2ch.net"
コピーワンス,コピワン-->COPY ONCE(I do not know this word is right as English.)

Your translations are undoubtedly much better than babelfish ones,

Thaks a lot.It seems that babelfish English is same value as I did.
I will transrate correctly.

Diary translation:

http://www.marumo.ne.jp/db2004_2.htm#9

Changed the DNS entry at 24:00 JST (15:00 GMT) as planned. The access log at the old server is stopped at 00:10, so all seems well. Thanks to everyone who cooperated and stopped their clients.

I will stay awake till 01:30 JST (16:30 GMT) in case of trouble. I will sleep after that because I have work tommorow. I wonder how low the Load Average goes down.

<><><>

Even with files placed on MFS, the server gets slow with heavy access on user.cgi(First time I've seen "reached max client" on apache error.log). TODO: rewrite user.cgi seriously. It's past 01:30, and the server is up, so to bed.

<><><>

To Mr. 202.224.183.254 (eaosk2-p253.hi-ho.ne.jp). Please check your PC. The repeated GET_ID request on c2/bf/3rd.cgi from this IP address is causing heavy load on the server.

If the repeated requests don't stop, I will have to have a talk with hi-ho.ne.jp admin. It's a burden I don't want to take.

<><><>

I dropped user.cgi execute bit because of high load. Will rewrite and replace today.

<><><>

Configured server to stop user.cgi when the load is high. If the load average for the most recent 1 min goes over 4.0, user.cgi will stop. (Not a final solution)

<><><>

Changelog: load average threshhold for stopping user.cgi changed to 2.0. ID validity timeout shortened to 6 hours. We now return "ng - your IP is black listed" to 202.224.183.254. Haven't contacted hi-ho yet. Will decide on a more final reaction later.

<><>>

I think "Matsusita Corp." returned by jpnic whois for hi-ho is only because it is operated by Matsushita. The narrow IP range is because hi-ho is using multiple class C addresses. Access from within [matsuhita?] should be through proxies with DNS name <jewel name>.mei.co.jp.

It is probable that its by a [Matsushita] worker who has signed up to hi-ho, but not even through a proxy? unlikely. I just think its just some poor PC thats been rooted. Although the timing when it stopped for the first time seems too timely.

<><><>

Found the cause of occasional maxing out of HTTP. It was caused by user.cgi and data backup program that saved contents of MFS to hdd. The two processes were deadlocking on multiple resources. I fixed the backup program at 19:30.

The GET_ID request is still going on from a different IP, but I have finished purging those IDs so the impact on performance should be minimal. The ID validity timeout is back to 24 hours.

(I did not finish the transrate diary on 8 web sun yet.)

Marumo wrote helpful notices today.
I transrate it first.

13feb fr AVHDD crack [45] Q&A
[Q1] Logged, "[E] failed on get_id() - XX wait YY sec" (The number of XX and YY is increased )
[A1a] Can you see http://www.marumo.ne.jp ? If you can't,fix it good.

[A1b] If you can see http://www.marumo.ne.jp ,There is a personal firewall software(ex:ZoneAlarm etc.) standing in c2bf clients' connecting, or You do not make a proxy configration.
C2bf clients want permission by a personal firewall software.
Make a proxy configration in c2bf clients,same as web browser's one.

[Q3] Logged, "body[0] = ng - your ID is not exist on the server" or "[E] failed on get_block()" and,stopped.

[A3] When 24 hours have passed since c2bf clients got ID,and C2bf clients did not send reports,
The server will kill your ID.
Delete your registry in "HKEY_CURRENT_USER\Software\marumo\c2bf.exe".And restart the clients.

[Q4] Logged, "body[0] = ng - reported 'key/code' pairs are missmatched. please contact admin and report your environment detail." or "[E] failed on report()"

[A4] The server send a key and encryption with blocks.
He is compareing your clients' key and encryption as his ones.
Difference exists,it is looged.
If your PC is accelated(CPU clock is overdrove),stop it.
Accelated clients may be made a wrong report.Althouth It is send the block has right answer.

If your PC is NOT accelated,send a report to me(the version of client,and PC enviroment)
***
I was sick on a couple of days,I had a poor appetite.
I do not have much fever.I'm okay,.....may be.

I payed the fee that was update domain marumo.ne.jp.
I must swich the DNS and mail server to new server.
And reopen Bug Report BBS.

Hi.
The porpouse of the form in the team info page.

By using those 3 textboxs, you can leave your team,
and shift to another team.

You should enter your ID into the first textbox named "ID".
The team that you wanna shift to, the 2nd one named "Move to".
A password of the team, the 3rd one named "Password".

If you shift the team, the blocks that you've reported will be
taken off the old team and added to the new team.

9 feb Translated.(thanks)
13 feb Translated.
14 feb Not translated
16 feb Threw away.

By the way,I wonder how much degree oversea teams/people understand of the c2bf
project.
Now we are searching a key that is only one on Marumo's Rec-POT.
Even if the present analysys is succeed,all Rec-POT is not cracked.
And even chances of finding that are rather low, S-Box could be different,
Marumo could make a mistake in calculation.

1.The key we are searching could not find may be.
2.If the key is finded,it is only one Marumo's Rec-POT.
3.Finded key's S-box is correct,Marumo's Rec-POT is cracked.
4.Next plan is calculation before Time/Memory trade of force by distributed computing.
5.Time/Memory trade of force by distributed computing is succed,Rec-POT is cracked.
6.All Rec-POT owners can use raw TS files by computing about 1 hour.

Rec-POT is a product of a company IO-data(aiou-data) seled in Japan,a kind of HDTV.
http://www.iodata.jp...2002/rec_pot_s/
(Marumo owns Rec-POT 120S)
Rec-POT can not buy now.Sale is finished.

Many HDTV are produced by many companies in Japan.
Different encryption are used each HDTV.

It is so far to crack encryption.

S-Box:The circle of making encryption keys.
Marumo has S-Box,But that is not correct may be.

Hi, first of all thanks for the translations.

OK, this is a good detail of the problem.

Even if the present analysys is succeed,all Rec-POT is not cracked.
And even chances of finding that are rather low, S-Box could be different,
Marumo could make a mistake in calculation.


Well, I don't know the others, but I was considering a mistake on the calculations and I really don't care if this happened (everybody can have a bad day, or two... wel may be more ;) ), If it happens I will just hope the math gets fixed and then I should join again to the project.

mmm... these Rec-POT's are very interesting devices..., but the encription issue is really a pain (and babelfish translations are another kind of pain >_<).

it would be really nice if people posting in this topic either

b) those who post here refrain from using something that takes up half a browser

other than that, no problem.

[OFF TOPIC] sorry.

Well, call me too sensitive tonight, but I have been affected by the message. And as long as you are a guest, I cannot send you any private message and avoid polluting this thread.

The petition about signature is reasonable (after all this is an open thread for guests) and I remember now that signatures can be removed as per message.

About the avatar and being logged in: well, the avatar is a fast identifier so it is not gratuitous, and being logged allows me to edit the messages, as long as I am used to have mistakes and realise of them after the message has been posted (even after having read the message several times before posting), I will not log off (you can call me perfectionist until a certain degree too :u:).

About spamming: Hmmm,... over the years of life of the internet, spam has become almost an offense (¿have I said that?, hmmmph :barbas: take some stones and beards for the girls, call some friends and aim to my head, please). I will not try to convice anybody about the opposite, but as far as I know spam is allways related with money (chain e-mails are not spam, It's just shmuck rubbish). As long as Jabber and Firefox are free products, I don't consider that including a couple of links to these non profit organizations should be considered as spam. If you refer it is propaganda for the movie, <_< mmm... may be you are right, but... bah, "excuses are lik asses, everyone's got em and they all stink".

PS: I will not reply anything more outside the topic of the thread (just enought).

PPS: Hope you don't midn hand-made, full-text, usenet-old-school-style signatures

Simply,You can understand "Time/Memory Trade Off" means a way to crack encryption promptly.

I hope a bright translator will come. >_<

If it happens I will just hope the math gets fixed and then I should join again to the project.
