Achjo ... :( Jeden porod za druhym s Debianem 8.

jak vypada networking na tom RaPi?

ip a s
ip r s

co povi verbose pro apt?

config pro apt je v defaultu nebo nejak zmeneny?

Z jedne diskuze jsem se dozvedel radu ze pomuze /etc/modprobe.d/ipv6.conf

# Don't load ipv6 by default
alias net-pf-10 off
alias ipv6 off

a reboot. Nepomohlo.

Jak se da z commandline vynutit verbose rezim treba pro apt-get update? -V nefakci.

Workaround: do /etc/gai.conf si dej:

Krome modifikace gai.conf se i hodi toto:

/etc/systctl.d/disable_ipv6.conf

net.ipv6.conf.all.disable_ipv6=1

Techto parametru se kdyztak da najit na netu vice.

[pavlix]

Workaroundy jsou sice super, i když doporučuju spíš parametr jádra než sysctl, ale lepší by bylo donutit je vydat opravu.

[Jendа]

Koukni se (Wiresharkem, resp. tcpdump (-w)), co to posílá za DNS dotazy a jestli dostane i Ačkovou odpověď.

[pavlix]

A druhým krokem je strace -e network na daný software, aby člověk viděl, co ten software dělá.

[pavlix]

Na testování podobného typu bugů teď dělám projekt. Spousta sofware nedokáže korektně používat IPv4 a IPv6.

[Bill Gates]

Spousta sofware nedokáže korektně používat IPv4 a IPv6.

Ze se mezi tuto spoustu software bude radit i apt bych necekal. Bud se debian riti do nejakeho blackhole(u) nebo nevim. My na tom jedem urcite prumyslove systemy a misto wheezy zkousim jessie ac se znacnym odporem (nicmene co mi zbyva jineho) a zatim jeden pruser za druhym. Clovek aby se to pomalu bal cpat mezi zakazniky. Zlaty debian Wheezy.

To ze jsem chtel dnes nainstalovat mplayer a zjistil tenhle problem byla nahoda. Chtel jsem si cvicne pustit internetove radio z RPi misto z NTB, ale tohle me teda drsne prekvapilo. Mplayer v produkci mezi zakazniky nepouzivame i kdyz chysta se nahrada hlasoveho vystupu, zatim reseno hardwarove na HW mimo RPi.

[pavlix]

Ze se mezi tuto spoustu software bude radit i apt bych necekal.

Tak to mě nic nepřekvapuje, zatím mi testy neprochází žádný software, kromě toho, co jsem sám upravil. Teoreticky by mohly procházet webové browsery, kdybych na ně uměl napsat testy. Na druhou stranu bych čekal, že nástroj tohoto typu bude na pozadí používat něco na úrovni curl, kde je jistá šance, že ten fallback aspoň se zpožděním projde.

Podpora dual-stack prostředí je bohužel dost zoufalá. A podpora problémových konfigurací (jako je dropovné IPv6) ještě daleko horší. Do nedávna jsme neměli ani rozumný dual-stack ping. Myslím, že je to ještě dlouhá cesta.

Rek bych, debian only problem ...

Dualstack pouzivam roky - jak srv tak klient, a nenarazil sem nikdy na nic, v cem by byl problem. Narazil sem na widlich ... to treba kdyz nase slavny ministerstvo v ramci ukolu od vlady zprovoznilo IPv6 tak, ze sice DNS vracelo adresu, ale celej rozsah nebyl naroutovanej, takze proste neexistoval. Jo ... "oprava" spocivala v tom, ze rozsah sice existoval, ale na ty adrese byly vsechny porty za FW ...

Mainstream browsery si to resej ve vlastni rezii komplet ... tzn, i pokud si v systemu neco nastavis, browser ti to bude s prehledem ignorovat.

Nic, časem budeme mít generované statistiky a detaily balíčků, to pak bude jiná pohádka. Budeme to dělat pro Fedoru, ale kdokoli si může generovat reporty pro jiné distribuce. Browsery zatím v testech nemám, potřeboval bych nějaký CLI-only test nad nimi. Ale browsery jsou typicky na tom nejlépe z celé množiny software.

[⧠ A = 0]

Spíš nějaký individuální problém. Já mám dualstack na wheezy i na jessie, a nic takového jsem nepozoroval.

[Jendа]

Mně to na Sidovi funguje, teď jsem to vyzkoušel. Podle mě tam máš nějaký problém jako že ti DNS poslalo jenom AAAA nebo tak něco.

[Bill Gates]

Chmmm, tak ted to necekane proslo. Tak to byl asi fakt bordel na nejakem DNS.

Pritom jedine co jsem delal jsou upravy a pokusy ktere jsem uvedl vyse.

Takze asi nejaky docasny vypadek, ktery jsme ani zdejsim laborovanim nemohli ovlivnit, maximalne zdetekovat.

[R]

Mne sa to tiez parkrat stalo - a nie na Raspbiane, ale na normalnom Debiane. Riesenim bolo vzdy spustit to znovu, pripadne neskor.

[Andrej]

Jak se toho prosim zbavit?

Nejlepší asi bude dát si do pořádku nastavení sítě, aby normálně podporovala IPv6.
