Re: [Xen-users] http-traffic rejected, domU
Hi list,
responding for the archives.
Several parallel issues (as ever) lead to the behaviour I faced with.
DNS requests were rejected, IMAP and HTTP requests also.
DNS and IMAP were responsive from localhost, http not ... humm.
The main problem has been solved by setting a 0 for alle entries
of /proc/sys/net/bridge/bridge-nf-call-*
The problem with IMAP was a DNS issue, in not resolving the correct
sub-sub-domain, redirecting the requests to our main internet-server
(because of the tld); Fixed with corrected dns-entries for bind9.
The next issue was, that the webserver was rejecting any connection
attempt, also a localhost connection could not be established.
Found out, that it listens only to ipv6-addresses, editing the
apache.conf to Listen 0.0.0.0:80 resolved this problem. (There was no
Listen directive at all for the apache2 config, so arp did a guess)
Have a nice week :-D

Hi list,
i've been migrating our RAID1 system onto bigger drives. Therefor I've
setup a new dom0 with a 2.6.32-5-xen-amd64 kernel and Xen in version
4.0, because there was a 2.6.19 kernel and xen 3.0.1 causing problems
time by time.
My main problem is, that the domU running our intranet services
(webserver, mail, databases etc) is not responding or rejecting each
attempt to connect to a service.
I think that the root cause of the problem is located in the network
bridge settings from xen in dom0. Maybe someone can give me a kick in
the right direction to get these things up and running until the doors
are opened again :-)
As network option I've choosen (network-script network-bridge) and
(vif-script vif-bridge) leading to the following outputs.
$# brctl show
bridge name bridge id STP enabled interfaces
eth0 8000.00241d89463a no peth0
vif1.0
vif2.0
vif3.0
vif4.0
vif5.0
$# iptables -L -v : http://paste.debian.net/121061/
$# ifconfig : http://paste.debian.net/121060/
Many thanks for each hint :)
Bye
Markus
