RedHat 9.0 PPP warning: Unsupported protocol 0x8057 received

RedHat 9.0 PPP warning: Unsupported protocol 0x8057 received

Post by dchou4 » Sun, 05 Dec 2004 07:03:39


I connected my Toshiba PDA to my Linux RedHat 9.0 (kernel 2.4.20-8)
via USB. In the /var/log/messages, I get a warning message:

Dec 2 16:35:04 localhost pppd[3444]: Unsupported protocol 0x8057
received

Is someone trying to negotiate to IPv6? If so, why? How can I mitigate
this problem?

The communication between the PDA and the PC appears to work OK.

Thanks

2.4.20-8 was the out-of-box kernel. Since then, there were eight
updates from RH (the last to 2.4.20-31.9), and there _may_ have been
further errata available from download.fedoralegacy.org, although
officially, RH9 is beyond 'end-of-life'.

Yes


You'd have to look at the peer's setup.


What problem? The peer asked if you wanted to speak IPv6. Your
pppd replied "never heard of it". Apparently, you then negotiated
another protocol, probably IPv4, and things are great. Or is your
Red Hat box getting peni^Wprotocol envy? ;-)

For what it's worth, "linux.redhat.ppp" was a mirror of the Red Hat
PPP Mailing List, and it's pretty dead now - I've seen ten posts
since July first.
