hello all,
we have trouble from one datacenter in CH to reach a special DNS
server of one of our business partners in Argentina.
And only from this datacenter / IP-subnet.
but it doesn't look like a local problem.
from all other locations in Belarus/Brasil/Hungary/France/Germany and
also via ADSL-links of Sunrise in CH or via Cable Internet by
Cablecom in CH we can connect without any trouble.
so the problem can be:
- local
- on way
- remote side
see failure exemplary from one host in this datacenter:
[EMAIL PROTECTED] root]# nslookup
server ns1.allytech.com
Default server: ns1.allytech.com
Address: 200.49.145.101#53
mail.rebel-management.com
Server: ns1.allytech.com
Address:200.49.145.101#53
** server can't find mail.rebel-management.com: SERVFAIL
server 200.49.145.101
Default server: 200.49.145.101
Address: 200.49.145.101#53
mail.rebel-management.com
;; connection timed out; no servers could be reached
from all other locations in Belarus/Brasil/Hungary/France/Germany and
also via ADSL-links of Sunrise in CH we can connect without any
trouble:
[EMAIL PROTECTED]:/home/admin# nslookup
server 200.49.145.101
Default server: 200.49.145.101
Address: 200.49.145.101#53
mail.rebel-management.com
Server: 200.49.145.101
Address:200.49.145.101#53
Name: mail.rebel-management.com
Address: 200.49.145.27
we contacted already our provider of our datacenter, but we think the
problem is at the end DNS, or on the way, because also every trace
from any location shows trouble near to this DNS:
12 cablevision-s-a.tengigabitethernet3-4.ar3.eze1.gblx.net
(207.136.166.242) 334.160 ms 331.279 ms 332.844 ms
13 * * *
14 * * *
15 smtp1.dnscheck.com.ar (200.49.145.101) 339.278 ms 341.718 ms 364.889 ms
and we fond only problems with this single DNS there.
(sure, can be also local by our provider - we will see - but can not
believe it)
Please do me a favor:
try from your datacenter to resolve via this DNS
Default server: ns1.allytech.com
Address: 200.49.145.101#53
to resolve
mail.rebel-management.com
and report also problems by connecting this DNS with infos of your
provider to:
[EMAIL PROTECTED]
many thanks in advance
stephan
