hi, i have a problem with our small home network, maybe someone among you can find the mistake. i may be blind by now. ;-)
the situation is like this: we have three pcs alltogether. the flavour of debian on pc2 and pc3 is sid, originating from the brilliant http://www.kanotix.de live cd eliminating problems of knoppix consisting of a mixture of testing, unstable etc. the system itselv appears to be quite great. pc1 this is the firewall ipcop, one nic via pppoe connected to the outside world, one to pc1 pc2 is connected to pc1 ipcop and can access the net without any problems. pc3 also debian sid, without problems, connected to pc2 but not to the net. pc1: 192.168.0.27 pc2: 192.168.0.13 und 10.10.10.2 pc3: 10.10.10.1 i chose this layout because i had a similar layout already running some time ago with windows. there must a one small mistake somewhere i cannot find even though searching & thinking for quite a few days now. below further details concerning the pcs. the resolv.conf for pc1 makes me think a little, it does get the dns server via my provider. well, it has always been like this & is still working, so this should not be the problem. pc2 and 3 can communicate without any problem, nfs is working and pc3 can ping both of pc2's nics. but it cannot ping pc1, not to mention surf the net. i hope one kind soul might be able to help me, i have been searching & rtfm for some time now. thanks, akraix ######################################################################## pc1 (firewall) ######### ######### ifconfig pc1 eth0 Link encap:Ethernet HWaddr 00:80:AD:05:28:E4 inet addr:192.168.0.27 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:319726 errors:76022 dropped:0 overruns:0 frame:0 TX packets:284074 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:131220640 (125.1 Mb) TX bytes:99494524 (94.8 Mb) Interrupt:5 Base address:0x7f00 eth1 Link encap:Ethernet HWaddr 00:08:A1:4D:EF:BB inet addr:1.1.1.1 Bcast:1.1.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:302045 errors:0 dropped:0 overruns:0 frame:0 TX packets:323304 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:102305713 (97.5 Mb) TX bytes:132832227 (126.6 Mb) Interrupt:9 Base address:0xbf00 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:37 errors:0 dropped:0 overruns:0 frame:0 TX packets:37 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:3393 (3.3 Kb) TX bytes:3393 (3.3 Kb) ppp0 Link encap:Point-to-Point Protocol inet addr:82.82.220.6 P-t-P:145.253.4.140 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MTU:1492 Metric:1 RX packets:16451 errors:0 dropped:0 overruns:0 frame:0 TX packets:15883 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:8695229 (8.2 Mb) TX bytes:4315235 (4.1 Mb) #########routing pc1 Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 145.253.4.140 * 255.255.255.255 UH 0 0 0 ppp0 192.168.0.0 * 255.255.255.0 U 0 0 0 eth0 1.1.1.0 * 255.255.255.0 U 0 0 0 eth1 10.0.0.0 chaos-maniac 255.0.0.0 UG 0 0 0 eth0 default 145.253.4.140 0.0.0.0 UG 0 0 0 ppp0 ######### /etc/hosts pc1 127.0.0.1 localhost 192.168.0.27 waechter 192.168.0.13 chaos-maniac 10.10.10.2 chaos-maniac 10.10.10.1 tobi-strom ######### /etc/resolv.conf pc1 nameserver 127.0.0.1 pc2 ######### eth0 Protokoll:Ethernet Hardware Adresse 00:50:FC:3B6:7F inet Adresse:10.10.10.2 Bcast:10.0.0.255 Maske:255.0.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1065 errors:0 dropped:0 overruns:0 frame:0 TX packets:35 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenlänge:1000 RX bytes:167934 (163.9 KiB) TX bytes:2528 (2.4 KiB) Interrupt:16 Basisadresse:0xc000 eth1 Protokoll:Ethernet Hardware Adresse 00:50:BF:90:21:46 inet Adresse:192.168.0.13 Bcast:192.168.0.255 Maske:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:63561 errors:0 dropped:0 overruns:0 frame:0 TX packets:64020 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenlänge:1000 RX bytes:27329998 (26.0 MiB) TX bytes:5932680 (5.6 MiB) Interrupt:17 Basisadresse:0xe000 lo Protokoll:Lokale Schleife inet Adresse:127.0.0.1 Maske:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:2601 errors:0 dropped:0 overruns:0 frame:0 TX packets:2601 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenlänge:0 RX bytes:210015 (205.0 KiB) TX bytes:210015 (205.0 KiB) ######### /etc/network/interfaces pc2 #
