Connecting to localhost using PPPoE

zWaR · 10-13-2005, 03:40 AM

Hello!

I have a web server directly connected to a ADSL modem. So the connection is PPPoE and works without a problem. I'm having just one issue, as i want to connect to localhost, for example using http://localhost or http://127.0.0.1, it doesn't work. The server is 100% ok, because the connection works if i use a proxy. Why is this so?? If i run rc.inet1, which enables IP retrieving using dhcp (i'm using Slackware 10.1) i'm albe to connect to localhost, but the Internet connection doesn't work any more.

I'm really new to PPPoE, so i have no idea how to fix that (proxies are not actually a fix!).

Please help if you can!

I have localhost added in /etc/hosts/, web server is running, iptables are down.
The connection to localhost is still not working.... (yes i'm talking about ordinary browser connection (port 80))

Oh, i noticed something else! Nmap dumps this message, as i try to scan ports on 127.0.0.1

Code:

$ nmap 127.0.0.1

Starting nmap 3.75 ( http://www.insecure.org/nmap/ ) at 2005-10-14 07:17 CEST
WARNING:  Could not determine what interface to route packets through to 127.0.0.1, changing ping scantype to ICMP ping only

There are several possible reasons for this, depending on your operating system:
LINUX: If you are getting Socket type not supported, try modprobe af_packet or recompile your kernel with SOCK_PACKET enabled.
*BSD:  If you are getting device not configured, you need to recompile your kernel with Berkeley Packet Filter support.  If you are getting No such file or directory, try creating the device (eg cd /dev; MAKEDEV <device>; or use mknod).
SOLARIS:  If you are trying to scan localhost and getting '/dev/lo0: No such file or directory', complain to Sun.  I don't think Solaris can support advanced localhost scans.  You can probably use "-P0 -sT localhost" though.


QUITTING!

I looked in /usr/src/linux/.config for SOCK_PACKET and didn't find it!
As suggested i tried to use `-P0 -sT localhost`, that's the result:

Code:

$ nmap -P0 -sT localhost

Starting nmap 3.75 ( http://www.insecure.org/nmap/ ) at 2005-10-14 07:18 CEST
All 1663 scanned ports on localhost (127.0.0.1) are: filtered

Nmap run completed -- 1 IP address (1 host up) scanned in 345.168 seconds

But connection to localhost is still not working...

so u mean once u type http://127.0.0.1 in the browser then ur apache server come up ?

i think try look at /sbin/ifconfig see is there got 127.0.0.1

then check ur apache config under Port 80

off hostname lookup

if got LISTEN IP remove the ip

use - NameVirtualHost *:80

then do apachectl configtest then if ok restart apache then retry at ur browser

Routers, i did what you suggested, but it didn't work.

I tested many proxies, all working ones opened the pages on my server, so i believe apache conf is ok. http://127.0.0.1 is also working if i start dhcpcd (but then my i-net connection is gone), so the problem has to do something with PPPoE configuration (maybe there's a kernel module missing or something...) and not with apache conf files.

this info is need to help u more further also easy for others give opinion
