Need help turning off bootpd

UNIX SCO
1

OSR 5.0.7 patched with MP 5
The syslog is flooded with messages:

 
May  9 13:42:12 asiwc bootpd[14963]: IP address not found: 192.168.230.215
May  9 13:42:13 asiwc bootpd[14963]: IP address not found: 192.168.230.142
May  9 13:42:50 asiwc bootpd[14963]: IP address not found: 192.168.230.202

The system should not have bootp running at all, I believe this bootp problem started as a result of someone's trying to configure the system and not having a good understanding of what he was doing.

What I did so far:

1 commented out bootps line in inetd.conf (it was last line)
so now the file has this:

 
grep -v '^#' inetd.conf
ftp     stream  tcp     nowait  root    /etc/ftpd       ftpd -a
telnet  stream  tcp     nowait  NOLUID  /etc/telnetd    telnetd

chargen dgram   udp     wait    root    internal

imap    stream  tcp     nowait  root    /etc/imapd imapd 
swat stream tcp nowait root /usr/lib/samba/sbin/swat swat

restarted inetd:

 
kill -HUP `cat inetd.pid`

The syslog still shows bootp messages added every couple of minutes. What could be done to stop it and make sure it won't re-start later?

Thanks in advance,

Try restarting tcp.

#/etc/tcp stop
#/etc/tcp start

Thank you, jgt.

I am not at site, can I possibly do this after work hours:

# at now + 1 minute
tcp stop;
tcp start;
ctrl-d
# exit

Will I be able to telnet back a few minutes later?

Put the two lines into a script, and run the script. Surprisingly it doesn't seem to disconnect anybody (at least 99 times out of a hundred.)

Worked, thank you. Indeed I was surprised to run stop/start and nobody dropped connection.
