Divny ping - DLOUHE

[Pavel Trubl]

Zdravim,
nainstaloval jsem RH 6.1 CZ + sit.karta Micronet (Realtek 8029). IP
karty je 10.1.1.109, IP brany je 10.1.1.9, IP DNS provajdra je
62.229.56.1. Ping na moji kartu ukaze spravne toto:

# ping 10.1.1.109
PING 10.1.1.109 (10.1.1.109) from 10.1.1.109 : 56(84) bytes of data.
64 bytes from 10.1.1.109: icmp_seq=0 ttl=255 time=0.2 ms
64 bytes from 10.1.1.109: icmp_seq=1 ttl=255 time=0.1 ms
64 bytes from 10.1.1.109: icmp_seq=2 ttl=255 time=0.1 ms
--- 10.1.1.109 ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 0.1/0.1/0.2 ms

Ping na branu ukaze toto:

# ping 10.1.1.9
PING 10.1.1.9 (10.1.1.9) from 10.1.1.9 : 56(84) bytes of data.
64 bytes from 10.1.1.9: icmp_seq=1 ttl=255 time=0.1 ms

--- 10.1.1.9 ping statistics ---

round-trip min/avg/max = 0.1/0.1/0.2 ms

Ale ping na DNS ukazuje nejake divne udaje:

# ping 62.229.56.1
PING 62.229.56.1 (62.229.56.1) from 10.1.1.109 : 56(84) bytes of data.

Nevim, co to je to REDIRECT HOST (NEW NEXTHOP: 10.1.1.1)
No a z toho asi prameni problem, ze ping ven nejde:

# ping 192.250.155.29
PING 195.250.155.29 (195.250.155.29) from 10.1.1.109 : 56(84) bytes of
data.

Vsechny pakety se ztratily a ja vubec netusim proc. Kdyz kabel ze
sitovky strcim do druheho PC (RH 6.0, karta Planet-Realtek 8029) tak
vechno funguje, vypis pingu je normalni. Jeste jsem nezkousel prohodit
sitove karty, ale to az naposledy. Pro uplnost jeste nekolik vypisu:

Predpokladam, ze to bude nejaka hloupost, ktere jsem si nevsiml. Jsem v

bude potreba, poskytnu jakekoliv jine vypisy.
