207 | ** | |
208 | ** 1) user telnets in and gives only "NICK foobar" and waits | |
209 | ** 2) another user far away logs in normally with the nick | |
210 | ** "foobar" (quite legal, as this server didn't propagate | |
211 | ** it). | |
212 | ** 3) now this server gets nick "foobar" from outside, but | |
213 | ** has alread the same defined locally. Current server | |
214 | ** would just issue "KILL foobar" to clean out dups. But, | |
215 | ** this is not fair. It should actually request another | |
216 | ** nick from local user or kill him/her... | |
