Hardware / Doporučte USB DVB-S2 kartu
« kdy: 13. 10. 2015, 13:09:46 »
Shanim do USB levnou DVB-S2 kartu.
Zatim jsem nasel TBS 5922SE (linuxtv) a DVBSKY S960 (linuxtv).
Obe stoji kolem 1600 Kc.
Nevim, kterou vybrat. Mate s nimi nekdo zkusenosti? Ktera ma lepsi podporu v linuxu? Chci ji pouzivat v kombinaci s Tvheadend.
Funguji bez problemu i na ARMu? Rad bych zkusil Raspberry2.

Jak to myslis? Nepouzivat "-use-the-force-luke=spare:none" ale misto toho nejdriv BD naformatovat a pote palit?
Takze bych pak pouzil:

Software / Podteceni bufferu při vypalovani Blu-Ray
« kdy: 18. 09. 2015, 13:33:24 »
Nedavno jsem si koupil na eBay externi USB3.0 Blu-Ray vypalovacku. Je v ni notebookova mechanika Panasonic UJ-240. Mam to jenom na zalohovani velkych objemu dat.
Ve Windows vypalovani funguje, ale v linuxu ne.
V Linuxu mi bez problemu funguje cteni. V Ubuntu neumi ani Brasero, ani K3B vypalovat Blu-Ray. Podle oficialniho navodu mi to nefunguje. K3B okamzite po zacatku vypalovani oznami podteceni bufferu a medium za 25Kc muzu vyhodit.
Nasel jsem navod na vypalovani Blu-Ray z terminalu. Zkompiloval jsem si nejnovejsi cdrtools. Vypaloval jsem pomoci prikazu:
Muzete mi prosim nekdo poradit, jak v Linuxu funkce palit Blu-Ray?

Hardware / Příjem satelitní TV v Linuxu?
« kdy: 17. 09. 2015, 01:12:46 »
Rad sleduji TV z mobilu, nebo notebooku. Za timto ucelem mam v domacim serveru dve DVB-T USB karty. Na serveru mam nainstalovany TVheadend, na mobilu TVHClient a na notebooku VLC. Vse funguje dobre.
Nedavno jsem dostal starsi 60cm SAT parabolu s nejakym LNB (ma 1 F konektor). Uz delsi dobu jsem uvazoval o vyzkouseni SAT TV a tohle je pro me velka motivace k vyzkouseni.
Nikdy jsem satelit nemel, takze o teto problematice nevim temer nic. Proto mam hodne zacatecnickych dotazu.
Mym cilem je pripojit SAT do tvheadendu, nebo jineho programu a moct koukat z mobilu a notebooku v LAN.
Nebudu mit pripojenou zadnou TV, chci pouze PC.
Co vsechno potrebuji?
Protoze asi bude jako u DVB-T potreba na sledovani vice stanic soucasne vice tuneru, tak LNB se 4 vystupy?
Nektere LNB maji uvedenych 9,75-10,6 GHz a jine 10,7-12,75GHz. Ktery potrebuji? Zalezi to na prijimane druzici?
Abych nemusel tahat ze strechy hodne koaxialu, rad bych sloucil DVB-T a SAT do jedno koaxu. Staci takovyto slucovac a dole u PC rozbocovac?
Na DVB-T mam levne USB karty z eBay v cene asi 150Kc za kus a funguji vyborne. Co potrebuji na DVB-S? Staci treba tato krabicka? Levnejsi se mi najit nepodarilo.
A ted pro me nejvetsi neznama - jak je to s dekodovanim? Je potreba mit CA modul a jak ho pripojit k PC? Nebo je mozne dekodovat softwarove bez karty?
Jak moc je dekodovani narocne na CPU? Muzu uvazovat o Raspberry, nebo je potreba vetsi vykon (napr. Core i3)?

RDP ma vestaveneho klienta ve Windows - jasny plus pro RDP.
Zatim jsem zkousel pouze na LAN, takze nevim jak to bude s datovym tokem, ale VNC je hrozne nenazrane.

Podle dokumentace kdyz uvedu do configu encrypt_level=high, tak se pouzije obousmerne 128bitove sifrovani. Asi RSA.

Pak je tam jeste RC4 a nejaka vymena klicu. Pokud se nepletu, tak se v dnesni dobe doporucuje RSA minimalne 2048. Uplne to nechapu, muze mi to nekdo prosim vysvetlit?
Oficialni Ubuntu dokumentace to take moc neresi https://help.ubuntu.com/community/xrdp
Co se tyka kvality hesla, to je jasne. Heslo typu 123 je snadno prolomitelne. Ale tady se pouziva heslo u VNC, xrdp dela pouze proxy. Navic k obrazovce s vyberem spojeni se da pripojit uplne bez hesla. Takze kazdy se muze pripojit pres rdp, pak se teprve overuje vuci vnc. To se mi nezda zrovna idealni. Da se nastavit jmeno a heslo pro pripojeni primo na xrdp?
Jak to resite? Mit rdp bez hesla by bylo pekne a pohodlne, ale mam z toho strach.
Podle dokumentace kdyz uvedu do configu encrypt_level=high, tak se pouzije obousmerne 128bitove sifrovani. Asi RSA.

Citace
RDP has 3 security levels between the RDP server and RDP client. Low, medium and high. Low is 40 bit, data from the client to server is encrypted, medium is 40 bit encryption both ways and high is 128 bit encryption both ways. Xrdp currently supports all 3 encryption levels via the xrdp.ini file. RSA key exchange is used with both client and server randoms to establish the RC4 keys before the client connect.
RDP uses RSA key encryption. RDP uses SHA1 and MD5 hash algorithms. RDP uses RC4 cypher algorithm.
The public key is sent to the client in the MCS data. The public key containers the exponent and modulus and a signature. Originally the details of how the signature was generated was a mystery. There is now a utility for creating a new rsakeys.ini file in xrdp.
Low, medium and high encryption levels. The xrdp.ini files provides a setting for the encryption level. It the crypt_level setting in the globals section. Valid setting are 'low,' 'medium,' and 'high.' Low is 40 bit client to server encryption. Medium is 40 bit two way encryption. High is 128 bit two way encryption.
RSA key generation. xrdp comes with a predefined RSA public and private key. To be completely secure, you should generate your own rsakeys.ini file. For information on how to do this, email me, Jay – jay.sorg@gmail.com.
