Hi,,
The bt router is connected to a linksys vpn server/router, this then distributes the internet to our local network ,,, the ip of the bt router is 217.37.41.254 the internal network has an ip address of 192.168.2.??? i can ping the linksys box which has an ip of 192.168.2.254 but cant ping the bt router ,,but i can ping the machines through the other side of the vpn which are on a different ip (192.168.1.??? ) i have entered the vpn as the default gateway on the unix box ,, this is a first install of trying to get this box on the net ,, the unix box is just connected to a hub,,the other network card in the unix box has an ip that corresponds to our internal network (192.168.2.???) but isnt connected to anything ,,
Thank you

2. SuSE
I want to have 7 search domains in my resolv.conf, but it seems to like only the first six.
I read somewhere that the OS will only recognize the first 6 (or the first 154 characters). Is that the case with SUSE 10?
thx

CISCO_IOS2DLF.IN(1) LogReport's Lire Documentation CISCO_IOS2DLF.IN(1) NAME
cisco_ios2dlf - convert cisco logs to dlf format SYNOPSIS
cisco_ios2dlf DESCRIPTION
This script expects syslog-type logs from a CISCO IOS router on stdin. These look like e.g. Jul 3 00:00:39 router 40108: 4d09h: %SEC-6-IPACCESSLOGP: list FR_VA_in permitted udp 192.168.19.1(137) (Serial0/0.2 DLCI 120) -> 192.168.19.255(137), 2 packets Jul 3 00:02:39 router 40109: 4d09h: %SEC-6-IPACCESSLOGP: list FR_VA_in permitted udp 192.168.80.42(138) (Serial0/0.2 DLCI 120) -> 192.60.60.148(138), 1 packet Jul 3 00:02:39 router 40110: 4d09h: %SEC-6-IPACCESSLOGDP: list FR_VA_in permitted icmp 192.168.80.82 (Serial0/0.2 DLCI 120) -> 149.1.1.1 (8/0), 1 packet or Aug 19 04:02:34 gateway.foo.bar 218963: Aug 19 04:02:32.977: %LINEPROTO-5-UPDOWN: Line protocol on Interface BRI0:1, changed state to down Aug 19 04:02:34 gateway.foo.bar 218964: Aug 19 04:02:33.262: %ISDN-6-DISCONNECT: Interface BRI0:1 disconnected from 172605440 acme, call lasted 42 seconds Aug 19 04:02:35 gateway.foo.bar 218965: Aug 19 04:02:33.266: %LINK-3-UPDOWN: Interface BRI0:1, changed state to down Aug 19 04:02:38 gateway.foo.bar 218966: Aug 19 04:02:36.103: %SEC-6-IPACCESSLOGP: list 102 denied tcp 100.198.139.148(4652) -> 100.193.176.49(80), 1 packet Aug 19 04:02:45 gateway.foo.bar 218967: Aug 19 04:02:43.543: %ISDN-6-LAYER2DOWN: Layer 2 for Interface BR0, TEI 86 changed to down Aug 19 04:02:53 gateway.foo.bar 218968: Aug 19 04:02:51.471: %SEC-6-IPACCESSLOGP: list 102 denied tcp 100.74.103.1(2162) -> 100.193.176.98(80), 1 packet The outputted dlf files look like: 994118619 permitted icmp 192.168.80.9 - Serial0/0.2 DLCI_120 192.168.19.1 - 1 994118619 permitted udp 192.168.19.1 138 Serial0/0.2 DLCI_120 192.168.19.255 138 1 EXAMPLES
To process a log as produced by Cisco IOS: $ cisco_ios2dlf < cisco.log cisco_ios2dlf will be rarely used on its own, but is more likely called by lr_log2report: $ lr_log2report cisco_ios < /var/log/cisco.log AUTHORS
