1. PPP
1) zsmon 으로 여의치않아 delete 후 zsmon0 생성후 테스트 OK
lion# pmadm -l
PMTAG PMTYPE SVCTAG FLGS ID
zsmon0 ttymon ttya u root /dev/term/a b - /usr/bin/login
- 9600 ldterm,ttcompat login: - - n #
* client service disable 여서 문제가 되지않지만 server 는
port enable 이다. 즉, 우선 port a 를 disable 하고 admintool 또는
command 로 zsmon0 를 하나 만들어 사용한다.
2) zsmon0 delete 후 zsmon 생성후 다시 테스트 OK
lion# pmadm -l
PMTAG PMTYPE SVCTAG FLGS ID
zsmon ttymon ttya u root /dev/term/a b - /usr/bin/login
- 9600 ldterm,ttcompat login: - - n #
3) zsmon 생성후 PMSPECIFIC value change test
3-0) no services is certainly failed.
3-1) I (초기화만) (.../dev/term/a:I::/usr/bin/login...) : Failure
3-2) (terminal hardwire) (../dev/term/a:::/usr/bin/login..) : Failure
3-3) (dial in only) (../dev/term/a:::/usr/bin/login..) : OK
console 에 "lion# NOTICE: zs3:ring buffer overflow" messages display
3-4) b (bi-directional) (../dev/term/a:b::/usr/bin/login..) : OK
4) 결론은 port monitor 의 값이 중요하다. 예를 들면
asppp.log 에서의 delock line (term/a), Call failed: LOGIN FAILED,
timed out 같은 메세지는 두가지경우에 나타난다.
첫째는 port monitor 값이 적절치 않을때이고 나머지 하나는
시스템이 죽어있을때(rebooting 중) 이다.
5) Log
5-1)server log

즉, 첫번째는 /etc/uucp/Systems 에 내용이 없는경우
두번째는 /etc/uucp/Systems 가
wybee Never 로서 여기서 wybee 는 login account 임.
따라서 HANDSHAKE FAILED 가 일어나지않기위해서는 다음과 같이 되어야함.

# Machine-Name node name of the remote machine
