Can I do anything.
Scott Tuttle
I was working on my one linux box remotely and I seriously foobared
it. I was also working on my sendmail config at the same time. I
screwed up glibc on it or something because now I can no longer
authenticat witht he box, via ssh, or ftp. So now my sendmail is
down. Mind you my server is in Indiana. I am working in Cali. All I
can do when I get home is to rebuild the box. But for the time being
my webservices are working fine. My DNS was also on this box. So
this is where my serious questions start.
I am bringing up a third box to run mail services. I also want to do
dns on this box and update the dns entries in whois so that this box
forwards www requests to the current server but serves the mail
services. Suggestions on what I can do?
I also have a config problem in my current dns that I am bringing up
on this box. But it could be related to the DNS being up on those
boxes. I am testing my sendmail locally right now. I cannot send
email using elm to a us...@mydomain.com I get a "sendmail[20304]:
g1I5EOEl020302: SYSERR(root): MX list for mydomain.com. points back to
mail.mydomain.com" I believe my sendmail is setup right and its a dns
config error. I currently have in the domain file
;
; Zone file for mydomain.com
;
; The full zone file
;
$TTL 3D
@ IN SOA ns3.mydomain.com. hostmaster.mydomain.com. (
199802151 ; serial, tod date + tod serial #
8H ; refresh, seconds
2H ; retry, seconds
4W ; expire, seconds
1D ) ; minimum, seconds
;
NS ns1.mydomain.com.
NS ns2.mydomain.com.
NS ns3.mydomain.com.
MX 10 mail.mydomain.com.
;
localhost A 127.0.0.1
ns1 A oldrealip1
ns2 A oldrealip2
ns3 A newrealip1
mail A newrealip1
www CNAME ns1
ftp CNAME ns3
Is something setup wrong? I had my dns setup and working before but
since I will not be able to recover my zone files till I delete that
old box and mount the drives in another box I am starting from fresh.
I can get another real ip address. So I could just create two new
name servers and add them to the whois db. The only problem I do not
have reverse look ups for the new ips. Will that be a problem? Are
my other nameservers which are currently up going to cause me problems
with getting a workable solution up and running?
I really am just trying to get something setup so that the emails for
my domains aren't bounced. My email has been down for sometime
already and I am sure I have lost some emails.
Any help will be greatly appreciated.
Thanks

just a suggestion... if you want help, you should give the real domain
name and the real zone file. a lot of times, changing information
either creates errors that aren't in the real zone file, or gets rid of
errors that are.
giving the real information also allows others to use various tools to
troubleshoot your problem.
since DNS if inherently public information, there's very little to be
gained by obfuscating this information.

This is a sendmail configuration error. Go read the sendmail FAQ
as the answer is there.

I don't know about your other problems, but this is a fairly common
problem. What is happening is that the MX record for the domain is set
to 'mail.mydomain.com', but you have not included 'mail.mydomain.com' in
the list of domains that your mail server is to accept mail for (normally
done via the CW class in sendmail.cf [or the sendmail.cw file, or
relay-domains, whatever they call it nowadays]).

much fixed. I found out that my friend could log onto this remote box
from the console, my guess is pam is not required to log in on the
console. I had him ftp down a named.tar and extract it with the
updated entries. So I just updated the primary and seconday name
servers. Problem solved, at least until I have to unplug this box and
take it home.
Thanks for all the help ppl.
