Dustpuppy Posted September 12, 2004 Report Share Posted September 12, 2004 (edited) Having been warned off using the wizards, I'm trying to configure a network of two systems, both running Mandrake 10(OE), and it hasn't worked. Hardware config: Dante (desktop 'puter) connected to the internet with Speedtouch 330 USB modem. Connected to the hub from ethernet card (eth0). Aristottle (laptop) connected to the hub from ethernet card (eth0). Cables and hub work. Both firewalls are down. Dante's eth0 has IP 192.168.0.1, and has internet IP by DHCP from my ISP. Aristottle has 192.168.0.12 I can ping 192.168.0.12 from 192.168.0.1 but not the other way round. When Dante's firewall is on I get 'destination host unreachable', and when it is off I don't get anything - it's like the ping command has frozen after saying "PING". I can't get online from Aristottle either, neither by pinging, browsing by name (google.com) nor browsing by IP (216.239.59.99). Full setup is: Dante: /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=static IPADDR=192.168.0.1 NETMASK=255.255.255.0 NETWORK=192.168.0.0 BROADCAST=192.168.0.255 ONBOOT=yes MII_NOT_SUPPORTED=yes WIRELESS_ENC_KEY="" /etc/resolv.conf nameserver 212.67.120.148 # ppp temp entry nameserver 212.67.96.129 # ppp temp entry /etc/sysconfig/network HOSTNAME=Dante NETWORKING=yes /etc/sysctl.conf {contains} net.ipv4.ip_forward = 1 Aristottle: /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=static IPADDR=192.168.0.12 NETMASK=255.255.255.0 NETWORK=192.168.0.0 BROADCAST=192.168.0.255 ONBOOT=yes HWADDR=00:01:02:d2:3d:43 MII_NOT_SUPPORTED=yes WIRELESS_ENC_KEY="" /etc/resolv.conf nameserver 192.168.0.1 /etc/sysconfig/network HOSTNAME=Aristottle NETWORKING=yes GATEWAY=192.168.0.1 GATEWAYDEV=eth0 Any ideas what I should do?

Vdubjunkie Posted September 16, 2004 Report Share Posted September 16, 2004 Ok, first of all sounds like you got a good start to your troubleshooting. Ping is your friend as it is a very basic tool which will work even when DNS doesn't. The first thing I would do is make sure Dante's (192.168.0.1) isn't running some other type of security thing. I've beat my head against the wall and still can't think of it, but my server had a security tool load at boot time which kept me from accessing it remotely in any way. All I would have to do is get on the machine, do a ps auxw | grep securityutilityname get it's PID, and kill it. If nothing else, you may try doing a ps auxw and just looking through everything to see if there's something you don't recognize. Google it to see what it is. Kill anything you don't need. Typically if you can ping machine B from machine A, but not the other way around when they are on the same physical network, it is due to some type of a firewall/security deal.
