| BOOTP/DHCP client for klibc |
| --------------------------- |
| |
| Usage: |
| |
| ipconfig [-c proto] [-d interface] [-n] [-p port] [-t timeout] [interface ...] |
| |
| -c proto Use PROTO as the configuration protocol for all |
| interfaces, unless overridden by specific interfaces. |
| -d interface Either the name of an interface, or a long spec. |
| -n Do nothing - just print the configuration that would |
| be performed. |
| -p port Send bootp/dhcp broadcasts from PORT, to PORT - 1. |
| -t timeout Give up on all unconfigured interfaces after TIMEOUT secs. |
| |
| You can configure multiple interfaces by passing multiple interface |
| specs on the command line, or by using the special interface name |
| "all". If you're autoconfiguring any interfaces, ipconfig will wait |
| until either all such interfaces have been configured, or the timeout |
| passes. |
| |
| PROTO can be one of the following, which selects the autoconfiguration |
| protocol to use: |
| |
| not specified use all protocols (the default) |
| dhcp use bootp and dhcp |
| bootp use bootp only |
| rarp use rarp (not currently supported) |
| none no autoconfiguration - either static config, or none at all |
| |
| An interface spec can be either short form, which is just the name of |
| an interface (eth0 or whatever), or long form. The long form consists |
| of up to six elements, separated by colons: |
| |
| addr:server:gateway:netmask:interface:proto |
| |
| addr the local IP address |
| server the server's IP address (doubles as DNS server) |
| gateway default gateway |
| netmask netmask |
| interface name of the interface (empty string is synonym for "all") |
| proto the autoconfig protocol to use, as outlined above |
| |
| IP addresses and netmasks must be either absent (defaulting to zero) |
| or presented in dotted-quad notation. |
| |
| An interface spec can be prefixed with either "ip=", "nfsaddrs=", both |
| of which are ignored. These (along with the ugliness of the long |
| form) are present for compatibility with the in-kernel ipconfig code |
| from 2.4 and earlier kernels. |
| |
| Here are a few examples of valid ipconfig command lines. |
| |
| Try to configure eth0 using bootp for up to 30 seconds: |
| ipconfig -t 30 -c bootp eth0 |
| |
| Configure eth0 and eth1 using dhcp or bootp, and eth2 statically: |
| ipconfig -c any eth0 eth1 192.168.1.1::::eth2:none |

| From Russell's original README, and still true: |
| |
| The code in main.c is yucky imho. Needs cleaning. |
