Hali,
helyi geprol megy a fel es a letoltes, viszont tavoli geprol csak a letoltes megy.
A feltolteskor letrehozza az allomanyt 0 bit merettel, de a tavoli kliensnel Transfer timed out-ra fut.
A tcpdumpon latszik, hogy vagy 4* probalkozik, de ennyi.
A strace sem tul bobeszedu szamomra, legalabbis en nem latom, hogy mi a nyugje.

az ujsorokat en nyomogattam, hogy lassam amikor probalkozik.
Szerkesztes:
megoldva.
Megoldas:
mivel szabira mentem, atadtam a problemat par kollegamnak. Az egyik megoldotta:
"All,
It took us no longer than about 30 seconds to identify this trivial condition that was caused by the vmxnet3 driver. We changed eth0 in Vcenter from VMXNET3 to E1000, and now it works!
-
P.S.: When I say "30 seconds", I mean "2 hours, 30 tcpdumps and 1 reboot", and when I say "trivial", I mean, "OMFG"."
Azt hiszem soha ebben az eletben nem talaltam volna meg/ki.

Próbáltad a könyvtárra a 777-et?
Ugyanabból a subnetből, mint ahol a szerver is van, működik?
A kliens NAT mögött van?
Próbáltad "kikapcsolt" csomagszűrővel? (minden ACCEPT)

A konyvtar 777-es jogosultsaggal bir.
Ugyanazon a subneten vannak.
Nincs bekapcsolt csomagszures.
A letoltes megy, feltolteskor letrehozza a filet 0 merettel.
Sajna a verbos reszeket hiaba kapcsolgatom parameterekkel, semmi plusz logot nem kapok.

Juteszembe, a tftpd-vel én is szívtam sokat, de feladtam és helyette az atftpd-t használom.
Az legalább működik.

Nekem a tftpd-hpa valt be. Van sok, erdemes kiserletezni.

Nem eszi meg valami a túl nagy bejövő UDP csomagokat? Mi az 1.1.1.1 és 1.1.1.2 IP? Gyerek processzeket csinál, azokkal mi történik?

Hali,
nem azok a valodi ip cimek, csak mivel eles rendszerek ip cimeit nem szivesen szivarogtatom ki.
Valojaban semekkora allomanyt sem tud fogadni.
