Know Users (ku)
(Kuhn's Utility)
Please read ku.1 and ku.help.
ku.1 is from knife.1.
ku is a generic know users tool. You can know if your friends
come by watching all hosts specified by you.
Just enter
/usr/local/bin/ku
(or /usr/local/bin/wife, a clone to knife)
to use it.
I have no time to write its manual page, and just describe
its usage briefly.
Usage: ku -[f|m] host-file
-[w|i] info-file
-t timeout-period
-r refresh-period
-h (show help message)
m,i,t are compatible to "KNIFE". You can watch your friends
in a screen oriented browser system. There are fours levels now.
1. Hosts selection level
2. Host users level
3. Watching user level
4. Watching users specified level
You can watch users by "host", "user" or a group of "users".
The last kind of watching is like "knife".
I have write another script "Watch If Friends Exist", wife
(/usr/local/bin/wife) to do the last function solely
and roughly compatible to knife.
All commands are almost stolen from "TIN".
'q' to quit from last level.
'Q' quit complately regardless of which level.
'r' refresh right now.
'w' enter watching users specified in your information file.
'ctrl-z' suspend
'ctrl-c' quit rudely
'space' next page
'b' back page
'ctrol-L' redraw page
'/' forward search your friends
'?' backward search your friends
'return' go to next level.
BUGS:
after ctrl-z suspend, never "bg" it, or screen will be a mess.
TOTDO:
add 'h' to show help message
write man page.
add commands such as "talk,finger,mail" for user level.

If you met "segmentation fault and core dump" during
runing of ku, maybe I am replaceing a new ku binary.
Just remove your core. But you think it is rather
abnormal and not due to my replacement of it,
please tell me.
I just solve the problem of the low speed of arrow key movement.
And you can use "number" to select any entry as in tin.

If you want to "watch" as in "knife" from "ku", I
suggest you run "wife", or edit "wife" for your suit.
"wife" is a shell script using "ku".
(and press "w" in wife)
The default refresh time of "ku" is 60 seconds. I
think this period is a little too short and will
render high system load. For heavily loaded system,
I suggest you set into higher value, by
"ku -r 300" ( every 5 minutes )
The host file specified by "-f" or "-m" is the same as
in "knife". ( and "-w" or "-i" also same as in knife)
You must supply "-w" before using the mode for watching
a group of users listed in "-w" or "-i" file.
The searching path for "-f" or "-w" is done by
1. if the file path contains "/", no path concated.
2. if the file contains no "/", search ".", "$HOME",
and then /usr/local/etc/hosts.ALL for -f,
/usr/local/etc/hosts.watch for -w.
I will follow up here whenever I remember something.
And then can be used for "man ku".

default "time-out" is 1 second. So, if you feel
network is slow, you can set up "time-out" into
a larger value , say "ku -t 5".
(that is, many hosts are in dead state)
This value won't influence the response time in
hosts selection level, but will influence the
host users selection level.
You can see hosts state, in
below the field "#Users",
U: stands for "UP", machine is up and number of users will be shown.
D: stands for "Dead", host is dead or hard to reach.
C: stands for "Clear", host state is unknown.
TODO:
add "system load, up time", for host information.
configuable value for number of processes forked to query rusers state.
Now, we only fork 4 processes.

in hosts group level
'f': to group users by "from" host or domain.
You can view(watch) all logins from "dorm", "dorm10", "140.113", .....and
all the other possible "substring" in the "login from" entry.
'n': to group users by substring of "username".
You can view(watch) all logins with "cp","cp79", "tsai",.....and
all possible substring of username.
'L': sort hosts by load
'U': sort hosts by number of login users.
'h': show help menu
BUGS:
watching mode in not really watching now. You must knock a key
to view the watching effect. ( to improve idle run performance).
It is to be fixed.

I will stop to proceed KU now except bugs report.
New Options:
-N start watching mode by username
-W start ....... by information file supplied
-F ............. by from domain
-H by host
-p number of processes forked.
For example,
1. ku -F dorm (or f command in ku)
you can watch all logins from "dorm"
2. ku -N cp78 (or n command in ku)
you can watch all logins of cp78
3. ku -W -w .knife_info -f .knife_host (or w command in ku)
the same as "knife".
enjoy it. bye every csie netter. I have unsubscribe many groups
and I may not see your comments in usenet.

BUGS fixed for "watching".
Now "ku" can really be used for a "watching" tool and
won't introduce high load.
Default watching refresh time is 120 seconds and
use -r to override this value.

Further utilities for ku available. just try it.
(talk, ytalk, cytalk,...finger,..)
And default processes forked for ku is only 3 to
reduce system load. (default in rusers is 2)
refresh time is 120 seconds and timout time is 3.

The searching process is shown as xx/100. The first 50/100 is doing
"seaching users" and the remaining 50/100 is doing "searching host"
information. If you want to search users only, after the prompt
has been over 50/100, most users have been scanned. (except
some hard to reach hosts).
Querying "host" information is slower than querying "user" information.
Since the latter needs only to open /etc/utmp, but the former must
open /dev/kmem and read kernel data. (and through rpc).
(and so, if you want to view "rup" information, you must wait for
the prompt has been over 50/100)
It is my future work to add options for users who want to query
user information only.

If you can't see simple finger information for users in school
CC from KU, it may be due to my "spy" fingerd killed by
CC staff or, my friend's account has been expired.
If you have account in school's CC, and find KU failed
to display finger information for CC's users, try
ftp the file in
ccsun35:/home/inn/src/reader-nov/ku/myfinger/ccfinger
to ccsun10.cc.nctu.edu.tw
and run it there.
If you obtain "permission denied", it doesn't matter
becuase there have been one ccfinger running there.
Why I write this note there ? becuase I won't try
to maintain this server any more and my friend will
graduate. His account in CC will be expired.
And you will seldom see me in the net after these days.

1. For KNIFE fans:
If you just want to search friends quickly in a lightly
loaded machine, you can use
/usr/local/bin/wife -W -p 8
( please don't use this way for watching)
For heavily loaded machine, please use
/usr/local/bin/wife -W -p 1
2. For ordinary "rusers",
just enter "/usr/local/bin/rusers" without any options.
/usr/local/bin/rusers with options will run /usr/ucb/rusers.
3. For complicated "KU", you may try
1. /usr/local/bin/ku -h
2. /usr/local/bin/ku and enter "h" in the program.
I will write man of KU in this summer vacation.
