566 Part IV . Implementing Network Services in SUSE Linux Listing 20-4: (continued) DOMAIN= vonhagen.org DNS=204.127.202.4,216.148.227.68 DHCPSID=192.168.6.200 DHCPGIADDR=0.0.0.0 DHCPSIADDR=192.168.6.200 DHCPCHADDR=00:02:2D:31:B8:C8 DHCPSHADDR=00:30:65:3C:7E:22 DHCPSNAME= LEASETIME=4080 RENEWALTIME=2040 REBINDTIME=3570 INTERFACE= eth1 CLASSID= Linux 2.6.11.4-20a-default i686 CLIENTID=00:02:2D:31:B8:C8 Pay particular information to the DHCPSIADDR value, which is the IP address of the DHCP server from which this information was retrieved. If this is not the IP address of the system on which your official DHCP server is running, track down that system and either terminate or reconfigure its DHCP server or restart it on the correct Ethernet interface. Troubleshooting DHCP Servers If DHCP clients are not able to contact your DHCP server, use YaST to install the dhcp-tools package discussed earlier in this chapter in the SUSE DHCP Server Packages section. This package provides the dhcping utility, which you can use to attempt to contact your DHCP server and retrieve an IP address. The basic syntax of this command is the following: dhcping -c valid-IP-address -s DHCP-server-IP-address You must substitute the IP address of your client for valid-IP-address and the IP address of the DHCP server that you are trying to contact for DHCP-server-IPaddress. This command will either respond with the message no answer if it was unable to contact the DHCP server or the message Got answer from: DHCP-server- IP-address if the command was successful. You can use the dhcpdump command to obtain more detailed information about DHCP traffic on your network. The dhcpdump command, also provided in the dhcptools package, filters DHCP-related information from packet capture information retrieved by the tcpdump command, as in Listing 20-5.
