Yeah, more or less correct :) 

Then again Redhat guys have not yet commented about planned features for
RHEL6..

Of course, it's the current state of affairs as we think we know it.

Quite a few people appear to be quite insecure on the basis of 
what they think is/is not going to happen. The bottom line is 
crystal-ball gazing should be left alone and people should work 
with what's available in CentOS.

Bonding and network cards

Hi,
I have been playing this weekend with bonding on PCI netcards and found
that all of netcards I have, but old 3com, do not support MII. So
bonding is not going to happen with them. Do you have some pci netcards
supporting MII successfully running on bonging?
Thanks,
David Hrbáč

That is strange. But you shouldn't be needing mii, use_carrier should be
working with modern cards - if they come up at once.

I have bonding on 2 Broadcom NetXtreme II BCM5708 1000Base-T where the
card takes so long to come up that the bonding driver assumes the wrong
link mode (100baseT instead of 1000baseT).

But those cards do work with miimon (which uses miitool and/or ethtool).

Cheers,

Ralph

Hi,

I have seen this kind of problem (STARTTLS not available for a single
client but working for everyone else) when the client is behind a
CISCO firewall with the FIXUP SMTP configuration option enabled.
Disable it using "no fixup protocol smtp 25" on the firewall and try
again.

OK, I'm gonna test it with use_carrier. I have been playing with
arp_ip_target and miimon without luck.

>From documentation: 'It is critical that either the miimon or
arp_interval and arp_ip_target parameters be specified, otherwise
serious network degradation will occur during link failures.  Very few
devices do not support at least miimon, so there is really no reason not
to use it.'

And as to MII, ethertool on all netcard but old 3com shows no support
for MII. And as to bonging I want to get 802.3ad working.
Thanks,
