[pptp-server] Cannot Connect A Second Time

[Andrew McGregor]

Hello All,

Using Redhat 7.2 with PPTP Client 1.0.3 to connect to
a Redhat 7.0 system running PopTop v1.0.1, I have an
odd problem.

The client connects fine the first time and everything
works (telnet, ftp, etc...).  But after disconnecting,
the client cannot reconnect (using the pptp_command
PERL script).  It responds with the message:

[root at localhost ppp]# ./pptp-command
1.) start
2.) stop
3.) setup
4.) quit
What task would you like to do?: 1
1.) px
Start a tunnel to which server?: 1
warn[open_inetsock:pptp_callmgr.c:305]: connect:
Connection refused
fatal[callmgr_main:pptp_callmgr.c:128]: Could not open
control 
connection to 64.230.110.60
fatal[open_callmgr:pptp.c:243]: Call manager exited
with error 256

On the server side, there are absolutely no messages
after the first disconnect.  netstat says all sockets
are released, ps -ef says the pptp processes are gone.

The only clue on the server side is the error message
below, which occurs during the disconnect:
Apr 23 22:53:37 romulus pptpd[1049]: CTRL: EOF or bad

Apr 23 22:53:37 romulus pptpd[1049]: CTRL: couldn't

Any clues?
