That's because the command domainname and the systemcalls |
| 23 |
getdomainname(2) are return the NIS domainname, not the IP domainname. |
| 24 |
uname(2) returns the domainname of the machine the kernel was compiled |
| 25 |
on, at the time when it was compiled. To find the tcp/ip domain name |
| 26 |
of a system, use hostname(1). |

Yes, it is daft - but, that's what happens when an OS acquires a |

history, I suppose |
