Unhappy Compound Problems


Hello Team,

I have what I originally thought was a problem with my sendmail configuration. The symptom was that I could send mail locally to accounts on the system, but I could not send or recieve mail over the net.

Now, I'm beginning to think this is more of a DNS problem. Additionally I'm getting odd errors on my login screen of all places. The error looks like;

216.52.86 sent an invalid ICMP error to a broadcast.

After a while these errors scroll off the screen, with different IP's. I've looked into this and this appears to be firewall related. However, when I set up this installation I set the firwall to "none" as I plan on installing a different one.

My DNS records are as follows;

$TTL 86400
@ IN SOA NS1.SPEAKEASY.NET. bselzler.sezonline.com. (
2 ; serial
28800 ; refresh
7200 ; retry
604800 ; expire
86400 ; ttl
)


@ IN NS NS1.SPEAKEASY.NET.
@ IN NS NS2.SPEAKEASY.NET.
@ IN NS ns.sezonline.com.

@ IN MX 10 ns.sezonline.com.

@ IN A 216.254.0.9
@ IN A 216.231.41.22
@ IN A 64.81.55.27

ftp IN CNAME ns.sezonline.com.
www IN A 64.81.55.27


And the reverse mapping file;

$TTL 86400
@ IN SOA NS1.SPEAKEASY.NET. bselzler@sezonline.com. (
2 ; serial
28800 ; refresh
7200 ; retry
604800 ; expire
86400 ; ttk
)


@ IN NS NS2.SPEAKEASY.NET.
@ IN NS ns.sezonline.com.

9.0.254.216 IN PTR NS1.SPEAKEASY.NET.
22.41.231.216 IN PTR NS1.SPEAKEASY.NET.
27 IN PTR ns.sezonline.com.


What follows here is part of this conversation on the webmin list. Hopefully it gives some more background on the problem;
