DNS public host
Hy,
I have a little problem. I want to set up a server with DHCP, DNS, QVCS, Firewall, for replacement of the actual server. I've installed Centos 3.4 because I've installed before qvcs on centos and worked just fine. The network must be divided in 3 subnetwork. On eth0 I've made 3 vlan. The problem is that I can't connect this server to internet. I have public ip's. I can't connect this server nighter with a public ip and not even with a vlan ip. I belive it is a DNS problem. From the working server I can connect to the new one. The question is how do I put an public ip address of the host on the DNS server to accessible from the internet. About DNS I have experience only with 2000 server. Thank you. |
It's only a DNS problem if you are able to connect via IP address but not via hostname.
To map a hostname to an IP address, just add an A record to the domain's zone file. Like Code:
qvcs-server IN A 1.2.3.4 Something tells me, however, that this is not going to resolve your problem. If not, a slightly more detailed description of your setup and what you mean by "connect" (ping? run DNS queries against?) |
I managed to connect to the Internet. It was a routing and a DNS problem. Now I have another one. I've installed the files required for QVCS, I followed the qvcs tutorial, but not entirely, and the problem is that I can't find service qmail, it sais: "command not found", and so, when I try to login on squirrelmail i receive the error "ERROR: Connection dropped by IMAP server."
I have another problem: the routing table. In order to work the internet I introduced anothet route with the command "route add default gw". The problem is that when I restart the network service this route is erased. I couldn't find where to put it and stay there forever. Thank you. |

I found the missing package that were not installed for qmail. Tutorials incompleted ...
Can you please recommand me a tutorial for NAT setup? I have two private networks with ip's 192.168.20.1 and 192.168.10.1 and only one public ip. Thank you |

If that leaves you with questions, I recommend that you open a new thread, as this thread's subject is not going to draw in everyone who could help. ;) |
