Mam takyto problem so star-os. ak zapojim na kabelod routera jeden star-os v ap mode ako bridge a druhy oproti nemu v mode client , tiez ako bridge, za nim kablom PC, dostanem sa z tohto PC len po router. Ak to Pc napojim priamo na kabel k routeru, ktory ide do AP, dostanem sa vsade. Predpokladam teda , ze nejaky zrada je prave na spoji cez star-os.
Nastaenia star -os : 1 AP-mod, bridge 1 pre oba interfece, Star-os 2. Client-mod , bridge 1 pre oba interface. . Ipcky by nemali byt dolezite, ale aj to som pre istotu skusal rozne menit. Samozrejme ze PC na konci ma ip , Gw a netmask siete routera, ktory je na zaciatku, a cez ktory to nevie prejst. PRECO? |

a router na druhej strane ma routu pre segment v ktorom je PC na ten druhy router ?
[inac s neakymi podobnymi problemami sa na staros brodim dodnes, ale asi len podobnymi] |

pravdepodobne ide o zapojenie
=====ROUTER1====STAROS(ether1/wpci1) <-- --- --- Wifi -- --- --->STAROS2(wpci1/ether1)===ROUTER2====
moj predpoklad je, ze ked pingnes z ROUTER1 ROUTER2, tak je to len nejakym chaosom v IP alebo default route. |

mgx: pokial sa ale pokusa pingnut PC ktore je za radiovym klientom a routerom, tak to nie je chaosom v IP alebo routach ale asi v chybe bridge modu na star-os (ale z toho co napisal sa mi skor zda ze jeho problem je v tom co pises ty  ) |

kolega mi do telefonu vravel, ze z ROUTERA1 pingne ROUTER2
to znamena ze paket bridgom aj naspat prejde, len sa dalej nedostane. to podla mna znamena, ze problem bude na router2 (bud v default gw alebo v routovani).
ked vymeni star-os<---wifi--->star-os za kabel, tak to ide....
takze neviem...neviem.... bude sa to musiet otestovat, zial teraz tu nemam 2x wrap na test (maybe buduci tyzden).

| mgx: tak to ma presne ten isty problem co ja, staros nezvlada ked ma za sebou v mode klienta a bridge aj router (bez NAT), teda zvlada ak su kompy za routerom aktivne, ale pokial je tam neaky pasivny device tak nie... ale to asi bude idealne pokecat niekedy v reali, ti to vysvetlim... |

no, staci to poriadne popisat a mozem to poslat do VALEMOUNTu, nech sa
na to mrknu.
tzn. ze ROUTER1 aj ROUTER2 nemaju aktivovane NATko ak napr. za routerom1 nie su aktivni klienti, tak po case ROUTER1 z ROUTERa2 nepingnes?
Mgx
PS: radsej uprednostnujem pisane vysvetlenie alebo najlepsie nacrtok s prikladmi pingov. Pokec sa zle reprodukuje a vznikaju nedorozumenia.
PS2: moja rada. Ak chcete, aby sa problem riesil, treba to nakreslit a napisat konfiguraciu routerov aj co z coho ide/nejde pingnut a za akych podmienok.

Asi tak nejako.
ROUTER1 je pripojeny na router do in ternetu a za ROUTEROM1 je PC .
Z PC pingnem ROUTER1, ROUTER2 aj "router do internetu. " Dalej nic.
Funguje to aj opacne. Z PC vidim celu vnutornu siet , len sa nedostanem cez "router do internetu" .
Eth na STAROS maju ip z vnutornej siet . wpci maju lubovolnu ip z inej siete. |

nakresli mi to (pridaj obrazok) a uved pre kazdy pripojeny PC alebo router:
1. jeho rozhrania (nazov rozhrania, IP adresa, maska siete, default gw)
2. routovaciu tabulku
3. arp tabulku
4. ping vysledky na ostatne pc
5. uploadni nastavenie star-os (ak je to staros)
6. indikuj, ake sluzby bezia na danom PC/routeri, jeho OS, nastavenie NAT, IP MASQ, DNS. PROXY a pod.
v insom pripade ti pomoct nebudem moct helfnut. |

Alt-X Exit CPU Load: 3.9% | WRAP Edition v2.01.1 (build 4590)
vsetky rozhrania su opat napchate ako bridge 1
atherosova karta bezi ako klient
ROUTER2:
zo strany wrap-ov ma IP 10.8.253.18/28
default gw ma 10.8.253.17
za sebou ma (okrem ineho) siet 10.8.16.0/25, jeho IP do tejto siete je 10.8.16.1/25
v sieti sa nachadza PC napriklad s IP 10.8.16.32/25, default gw ma na 10.8.16.1 (rovnaky problem je ale aj s routrami a PC za nimi pripojenymi na ROUTER2)
z PC sa na ROUTER1 aj na net (ktory je dalej za ROUTER1) dostanem v pohode, ale:
pokial PC neposle na ROUTER1 alebo do netu ziaden packet po restarte WRAPov (alebo za uplynulych 3600 sekund), tak z ROUTERa1 alebo z netu sa na PC nedostanem !!! akonahle PC posle jediny packet ktory ide cez spoj medzi WRAPmi, tak sa nan uz dostanem.
hint: cele to ma cosi spolocne s niecim takym ako wireless - wpci1 - bridged client list; vyzera to byt problem starosu v mode klienta, ku ktoremu na radiovu stranu este packety od ROUTER1 na PC dojdu a ktory to uz dalej neposle do ethernetovej casti (skumane tcpdumpom)
dufam ze je kazdemu jasne ze ak mam v sieti kruhovu topologiu tak pri takomto bugu nedokazem otocit smer tecenia dat v tomto spoji (teda dat default gw na stranu klienta !!!)
okrem toho je to problem aj pri monitorovani radii (HW AP) za ROUTER2 kedze na ne pristupujem z net-u a oni do net-u svojvolne nic neposielaju.
zatial som to odrbal tym ze mam kazdych x minut z ROUTER2 pustany traceroute -w 2 -m 1 -s $IP 10.8.253.17 ktory posle packet akoby z PC majuceho $IP a teda zapise tuto IP do tej tabulky bridgeovanych klientov, ale iste uznate ze v pripade zeby za klientom bol z neakych dovodov uplink, tak je nerealne takto narvavat do toho cely IP rozsah internetu...
PS: nastavit routu pre dany segment na WRAP1 a/alebo WRAP2 nepomoze
PS2: aj tak si myslim ze lepsie by bolo nad toto si sadnut v reali a nakreslit to na papier a pokecat, ako pisat sem takyto siahodlhy prispevok |

a este som zabudol jednu perlicku:
z ROUTER1 mam problem so spojenim s WRAP2, ping obcas ide obcas nejde (ale pritom data medzi ROUTER1 a ROUTER2 pretekaju v pohode aj ked sa z ROUTER1 na WRAP2 neviem dostat, takze radiovy link je v pohode a bude to neaka SW chyba star-os) |
