Guest dcolley Posted December 2, 2004 Report Share Posted December 2, 2004 (edited) Hello, I have an odd situation that I can't resolve at home? I have: - Netgear ADSL Router with WiFi and 4-port hard wire (192.168.0.1 internal ip) No special config other than to route port ssh, http, https & 10000 to 192.168.0.2 - WinXP laptop (using it now) (192.168.0.12 on wire via DHCP) - Mandrake 10.0 CE server (192.168.0.2 on wire) I can: :D - ssh from laptop to mandrake (through the adsl router of course) - access the internet from laptop/WinXP - nslookup any domain from Mandrake What I can't do is: - [intermittent] ping external domains => "connect: Resource temporarily unavailable" - lynx or Mozilla from Mandrake => "Page contains no data" in Mozilla... I have the same issue, whether the firewall is up or down. Some configuration info: # cat /etc/resolv.conf nameserver 192.168.0.2 nameserver 192.168.0.1 # cat /etc/hosts 127.0.0.1 localhost 192.168.0.2 mandrake 192.168.0.3 mandrake 192.168.0.2 nw4host 195.155.155.1 nw4host # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 * 255.255.255.0 U 0 0 0 eth1 195.155.155.0 * 255.255.255.0 U 0 0 0 eth1 127.0.0.0 * 255.0.0.0 U 0 0 0 lo default 192.168.0.1 0.0.0.0 UG 0 0 0 eth1 Can anyone help with this? Many thanks in advance... Derek Edited December 2, 2004 by dcolley Quote Link to comment Share on other sites More sharing options...
Qchem Posted December 2, 2004 Report Share Posted December 2, 2004 Although it may not be the root cause of the problem, its probably not a good idea to have more than one entry with the same hostname in /etc/hosts. Additionally the same IP address appears twice in /etc/hosts with different hostnames. Are you obtaining your net info via dhcp on the linux box? I'm not sure the linux machines address should appear in /etc/resolv.conf - which is usually set by the router if you're using dhcp. Quote Link to comment Share on other sites More sharing options...
DragonMage Posted December 2, 2004 Report Share Posted December 2, 2004 I think your router don't do caching dns server or something since the nameserver in your mandrake goes to your router. Also, why do you put your mandrake ip address in the first line of your /etc/resolv.conf? And the weird thing is that there are the IP address for 192.168.0.2 goes into both Mandrake and nwhost (whatever it is) and then there is a 192.168.0.3 too for the Mandrake. Try deleting one of them. Try editing your /etc/resolv.conf and enter a real DNS server ip address. Quote Link to comment Share on other sites More sharing options...
Guest dcolley Posted December 2, 2004 Report Share Posted December 2, 2004 Mandrake IP is fixed. For clarity: The reason I had 192.168.0.2 in /etc/resolve.conf was: At one stage I thought there was a problem with the nameserver on the ADSL router as I wasn't getting any response for nslookup queries, so I configured bind on the Mandrake server (192.168.0.2), and forwarded requests from 192.168.0.2 to 192.168.0.1 I removed the additional entries from /etc/hosts and /etc/resolv.conf and restarted the network service: [root@mandrake etc]# lynx <any domain> Looking up <any domain> first Looking up <any domain> Making HTTP connection to <any domain> <--- at this stage teh nslookup is successful! Alert!: Unable to connect to remote host. lynx: Can't access startfile http://<any domain>/ Quote Link to comment Share on other sites More sharing options...
Guest dcolley Posted December 2, 2004 Report Share Posted December 2, 2004 This might be a problem with my ADSL router... After switching on the default DMZ ip address to 192.168.0.2, I am able to access the internet via lynx and intermittently via Mozilla...? Connections still get dropped and many pages in Mozilla "contain no data"... Quote Link to comment Share on other sites More sharing options...
DragonMage Posted December 2, 2004 Report Share Posted December 2, 2004 I think you have narrowed it down to the ADSL router. Try updating the firmware on that router. Also, try configuring the router into its default configuration without any port routing or DMZ. Quote Link to comment Share on other sites More sharing options...
arctic Posted December 2, 2004 Report Share Posted December 2, 2004 edit your /etc/modprobe.d/aliases file from alias net-pf-10 ipv6 to alias net-pf-10 ipv6 off or: install pump and dnsmasq or: open firefox/mozilla, type "about:config" in searchbar and type "ipv" in your search bar. change the ignore-ipv6-entry you find there from false to true (double click on it).

Qchem Posted December 3, 2004 Report Share Posted December 3, 2004 ah, the IPv6 problem - that didn't occur to me. Good thinking arctic!! dcolley: please let us know if that fixes things. Quote Link to comment Share on other sites More sharing options...
