Two solutions: |
| 21 |
|
| 22 |
1. Put your host into dyndns and ssh to that name |
| 23 |
|
| 24 |
2. You can ask peering routers for an ISP's IP range (it's public info and has |
| 25 |
to be that way). I forget the exact commands, but a mail thread on a different |
| 26 |
list covered this exact thing a while ago. You'll have to search the Glug-tech |
| 27 |
mail archives at http://www.linux.org.za/Lists-Archives/ from about 6 to 9 |
| 28 |
months back. |
