Page 2 - Some DNS help, setting up properly

I think I know what's is the problem. I'm really confused by the ISP saying that my public IP is 219.94.124.113. It should be 114 instead of 113. Right?

If I use that as the name server, I can resolve the address and get A/SOA record.

Now, I'll change the name server IP in my Registrar to 114. Should be working..... I think

Thank......you....

yeah, that's what I wanted to get at. 114 is the IP you used to query the dns crawler script every once in awhile, so I sent a query to that IP and vwella, it works. I noticed this soon after I made my last post.

So besides the icky LAN IP's in your dns results, and the lack of a reverse IP lookup zone, I'd say you're in good shape. TCP connections don't work, but that's not the end of the world.

hello, to every1..

I'm also new at this DNS Stuff..

i've been struggling with DNS, Mailserver, Linux, Firewall SETUP.. i'm new like i said, but now i think i can get my way around things..

I have configured my own DNS, Mailserver in Linux 9.0 (and 8.0).. but for some reason i can't send mail to a domain: anyuser@coppel.com .

i get error Name Server Time Out.. but when u send mail thru hotmail, yahoo.. it does arrive!!..

anyway, i wish if u could help me..

ALSO, u can check your DNS Setup and test at this location..

www.dnsreport.com and www.dnsstuff.com hope this helps..

BTW, my domain is merrytech.com.mx ... if u could help me, i have found some errors on the link above, but now i think its solved..

thanks in advance.

I have not been able to find any problems that would relate to name servers timing out. I have plugged "coppel.com" into www.dnsreport.com and did not find any errors, or warnings that were a big enough deal that you would have troubles sending mail to anyuser@coppel.com.

I did not actually TRY to send mail to "anyuser@coppel.com" until you give me a valid email address, and therefor permission to send you emails for testing. As of now, I only went so far as to confirm that there is a working SMTP server associated with the domain "coppel.com"

the problem i think i C in coppel.com, is that the TEST marks that is a LAME SERVER, meaning that : the server may never get updated.

i've read an article.. think is this link.. sort of. the same problem.. http://www.isc.org/ml-archives/bind...7/msg00279.html

that if i had an older nameserver, i COULD DELIVER mail to coppel.com , but since i have new one (bind 8 - 9).. and COPPEL.com uses an OLDER ONE, that's the problem.. if they updated there server, we wouldn't have any problems..

that's my theory..

but i would like if u could pliz helpme , to check my setup of linux, DNS, firewall and mailserver (sendmail)...

i have posted this problem not so long ago..

this is the link..

afther this, someone told me to check my dns in DNSREPORT.com AND DNSSTUFF.. THEY said that i had NO REVErSE POINTER.. THEY I HAD to tell my ISP to activate me as one os something like that..

so i read articles aND FOUNd out that is correct!, some servers "validate" your server if they can authenticate or something then they WILL receive your mail, if not, then not.

so i told my ISP to reverse my dns entry or something.. this i did in another post..

hmaldonado@coppel.com

You have a record which looks like this:

webmail.coppel.com. CNAME border.coppel.com.

Change it to this:

webmail.coppel.com. A 148.235.36.82

However, your other mail domain (gmail) is pointed to a different IP address. So maybe you should change it to:

webmail.coppel.com. A 148.235.36.83

If after you have tried both of those changes, and the problem persists, let me know.

U misunderstodd me, i'm not the owner of the domain coppel.com, i'm the owner of the domain merrytech.com.mx ..

i just want to know if my setup is correct.. cause i can't send mail to anyuser@coppel.com only by hotmail or yahoo..

i can't send mail to hmaldonado@coppel.com (any user) with the same domain..

i wanna know if the problem is mine or there's.. ?

Ok, I think I see what you're getting at. The article you posted for me had to do with MX records pointing to CNAME domains. That is not the case with copell.com so that is NOT the problem with your name server timing out.

The other thing where your IP address needs to reverse resolve to the mail server domain is also working properly.

And finally, to do exactly what you are saying does not work, I did the following request.

http://serialcoders.sytes.net/cgi-b...s=256&submit=DS

I asked your server to do a recursive request to find me the mail server associated with copell.com. It returned a domain, with that domain's IP address in the additional section. Once it returned it without an IP in the additional section, so I asked the server to do another request to find that IP, but there was no problems with that either.

Your server did not time out. I can find nothing wrong with your name server setup.

Hi.

I have a problem again .

The previous DNS settings is working perfectly. However, I had made some modification recently. First, I would like to use another server to run the DNS and web hosting, and I had named the server to "ns1". The same previous IP, DNS and NAT settings had been configured to this new machine.

All of my clients are able to access to the internet. But.....the internet users are not able to access my server. I tried to ping my server from the internet, but in vain. Any idea? FYI, my IP is 219.94.124.114.

Thanks in advance!

UDP request works

TCP request works

http://serialcoders.sytes.net/cgi-b...ype=A&submit=DS

Fixed the problem?

I just solved it!! It was the default basic firewall implemeted by the NAT service in Windows 2003 server. Haha... working now.

Thanks!

sorry for the wait..

so.. my email server / DNS Setup (merrytech.com.mx) is correct?? and the problem that i can't send email to anyuser@coppel.com is they're problem??

nothing to do with my setup??


BTW.. i'm interested in setting up webmail ... any tutorials??.. u think that if i can configure webmail i WILL BE ABLE to SEND MAIL TO THE DOMAIN @coppel.com ???

thanks again..

The problem is not with your DNS server, and it is not with their DNS server. Your DNS server works perfectly well resolving MX records. I just now did it again to confirm it with myself.

148.235.36.83

Try connecting to that server on port 25. Maybe the problem is with something else.

And as for webmail, it shouldn't make any difference as to whether you can send email to coppel.com. but I recommend formmail.pl for your script. A couple of years ago I know it was popular. dunno about anymore.

i did a telnet 148.235.36.83 25

and DID CONNECT!!..

but my PC network config.. is not using linux as my gateway..

if i use linux as my gateway.. i can't connect..

so... problem with linux not letting my thru??

from where is it sending mail to coppel and failing?
