[stunnel-users] Getting a "Peer suddenly disconnected" error

Thu Mar 8 23:45:04 CET 2007

Hey all,

  I'm getting this in the /var/adm/messages log on the server side when 
attempting to connect from the client:

Mar  8 22:23:33 SERVERNAME stunnel: [ID 821868 daemon.error] 
LOG3[27429:4]: SSL_connect: Peer suddenly disconnected

I have the server configured as follows:
cat /etc/stunnel/stunnel.test.conf
client=yes
debug=debug
cert=/etc/stunnel/stunnel.pem
[sunrpc]
accept=112
connect=127.0.0.1:111
TIMEOUTclose=10

This is started just by running stunnel with the config file and then 
starting rpcbind normally.

The client is configured as follows:
# cat /etc/stunnel/stunnel.test.conf
client=yes
debug=debug
cert=/etc/stunnel/imnxnsm0.pem
[sunrpc]
accept=111
connect=SERVERNAME:112

The error shows up when I attempt to run "rpcinfo -p 127.0.0.1".

Snoop is showing the following (adjusted to remove hostnames/ips):
CLIENT -> SERVER TCP D=112 S=63986 Syn Seq=867918817 Len=0 Win=24820 
Options=<nop,nop,sackOK,mss 1460>

Win=24820
SERVER -> CLIENT TCP D=63986 S=112 Rst Seq=209756754 Len=0 Win=24820

  I'm pretty new to stunnel, and am having a heck of a time getting this 
to work.  This configuration is the closest I've been to success so 
far.  Is there a better way for me to wrap rpcbind perhaps?

  Any help with this will be appreciated.
Thanks,
  Civil
