[lug] attbi: misconfigured BROADCAST addr, etc?

[Neal McBurnett]

On my AT&T broadband connection, I've seen dhcpcd returning results
since Tue evening, but they seem bogus to me and things aren't working
for me (linux redhat 7.1).

But I can use tcpdump to watch lots of arp activity, etc., on
the network, so I'm clearly connected.

In particular, the BROADCAST addr seems bogus, I would think, given
that netmask (and the clients I see arp requests for), that it should
be 12.253.87.255

 [root at localhost hollylew]# cat /etc/dhcpc/dhcpcd-eth0.info 
 IPADDR=12.253.87.170
 NETMASK=255.255.252.0
 NETWORK=12.253.84.0
 BROADCAST=255.255.255.255		????????????
 GATEWAY=12.253.84.1
 HOSTNAME=c1120488-a
 DOMAIN=attbi.com
 DNS=216.148.227.68,204.127.202.4,12.242.19.50,12.242.19.34
 DHCPSID=12.242.19.34
 DHCPGIADDR=10.80.74.1
 DHCPSIADDR=0.0.0.0
 DHCPCHADDR=00:E0:98:08:F8:CB
 DHCPSHADDR=00:30:7B:FF:28:70
 DHCPSNAME=
 LEASETIME=345600
 RENEWALTIME=172800
 REBINDTIME=302400

The 4-day lease is better than I've heard elsewhere, but worse
than @home.

I've tried this with no luck:
 ifconfig eth0:0 12.253.85.170 broadcast 12.253.87.255 netmask 255.255.252.0

I've disabled ipchains for this testing.

I'm near 40th and Baseline in Boulder (if there were a 40th....)

Any advice?


As a separate matter, I now can't reach mail.attbi.com from the
dial-up line I'm using in the interrim.  It was working earlier in the
week:

 $ telnet mail.attbi.com smtp
 Trying 216.148.227.71...

Just hangs for a while....

Do they now firewall out the rest of the world?
