Can't see WebServer from outside... Can see WebServer locally as http://localhost
I can't reach a domain on newly setup Redhat Linux webserver at my office
IBM Netfinity 3500
Dual P-II 266 CPU's
128mb RAM
9gb SCSI HD
Redhat Linux 7.1
Apache version 1.3.19
Anyone have any idea why I can't reach the domain:domainz.com-
I can browse to the default Apache web page on the local box at :
[localhost] and [127.0.0.1] and the static IP [36.116.72.105]
Note: I have a DSL Internet connection with 3 IP addresses (let's say 36.116.72.103, 104 and 105). I've switched some numbers around so the actual IP addresses are not shown to the whole world.
I go home and can't reach [domainz.com]. I can ping [36.116.72.105] just fine. I'm also running WebMin web based management software that listens on port 10000 and I can get to that login page by going to :
[domainz.com:10000]
Any ideas. I think it has something to do with DNS but I'm lost.
Goto [66.227.123.217/Network.gif] to see network layout
Supporting setup information already documented in this thread.

That domain resolves to:
202.46.160.52
I think you should ask your dns registrar to update the entry.

I didn't put the real domain or IP's up on the forum
Note: I have a DSL Internet connection with 3 IP addresses (let's say 36.116.72.103, 104 and 105). I've switched some numbers around so the actual IP addresses are not shown to the whole world.

Do you have any firewalls running?

no problem - got the e-mail. It looks like a firewall isse to me. RH 7.1 uses ipchains. Take a look to see if there are any firewall rules there:
ipchains -L
Also take a look on your router to make sure you have allowed port 80. You may want to check with your ISP to see if their terms of service permit you running a web server.

I hope I can do these things remotely, I'm at home using the web based mgmt tool (WebMin). This box is not behind the router.
This is what I get:
> ipchains -L
Chain input (policy ACCEPT):
target prot opt source destination ports
ACCEPT udp ------ NS2.ij.net anywhere domain -> any
ACCEPT udp ------ aslan.ij.net anywhere domain -> any
ACCEPT udp ------ anywhere anywhere bootps:bootpc -> bootps:bootpc
ACCEPT udp ------ anywhere anywhere bootps:bootpc -> bootps:bootpc
ACCEPT all ------ anywhere anywhere n/a
REJECT tcp -y---- anywhere anywhere any -> 0:1023
REJECT tcp -y---- anywhere anywhere any -> nfs
REJECT udp ------ anywhere anywhere any -> 0:1023
REJECT udp ------ anywhere anywhere any -> nfs
REJECT tcp -y---- anywhere anywhere any -> x11:6009
REJECT tcp -y---- anywhere anywhere any -> xfs
Chain forward (policy ACCEPT):

probably firewall..
run: redhat-config-securitylevel
and make sure WWW (http) has been opened. also if your behind a router firewall youll have to open the port there as well.. read your router documentation or ask your sysadmin.
