| 34 | * by Ted Lemon <mellon@fugue.com> in cooperation with Vixie

|
|---|
| 39 | * This client was substantially modified and enhanced by Elliot Poger
|
|---|
| 40 | * for use on Linux while he was working on the MosquitoNet project at
|
|---|
| 41 | * Stanford.
|
|---|
| 42 | *
|
|---|
| 43 | * The current version owes much to Elliot's Linux enhancements, but
|
|---|
| 44 | * was substantially reorganized and partially rewritten by Ted Lemon
|
|---|
| 45 | * so as to use the same networking framework that the Internet Software
|
|---|
| 46 | * Consortium DHCP server uses. Much system-specific configuration code
|
|---|
| 47 | * was moved into a shell script so that as support for more operating
|
|---|
| 48 | * systems is added, it will not be necessary to port and maintain
|
|---|
| 49 | * system-specific configuration code to these operating systems - instead,
|
|---|
| 50 | * the shell script can invoke the native tools to accomplish the same
|
|---|
| 51 | * purpose.
