Bug 694453

Description of problem:
condor_status return no answer or communication error while shared port is configured.

Version-Release number of selected component (if applicable):
$CondorVersion: 7.6.0 Mar 24 2011 BuildID: RH-7.6.0-0.3.el5 PRE-RELEASE-GRID $
$CondorPlatform: X86_64-Redhat_5.6 $

How reproducible:
always

Steps to Reproduce:
1. configuration:

Node1:
USE_SHARED_PORT=True
DAEMON_SOCKET_DIR = /var/lock/condor/daemon_soc
SHARED_PORT_ARGS = "-p 4080"
DAEMON_LIST=$(DAEMON_LIST),SHARED_PORT
SHARED_PORT_DEBUG = D_COMMAND
 
Node2:

CONDOR_HOST = <node1_hostname>
DAEMON_LIST=MASTER SCHEDD STARTD

2. set up firewall to drop all except 4080(and 22) on node1

Chain INPUT (policy DROP 21407 packets, 6391K bytes)
 pkts bytes target     prot opt in     out     source               destination         
1409K 1563M ACCEPT     all  --  any    any     anywhere             anywhere            state RELATED,ESTABLISHED 
13437 1264K ACCEPT     tcp  --  any    any     anywhere             anywhere            tcp dpt:4080 
 3454  262K ACCEPT     tcp  --  any    any     anywhere             anywhere            tcp dpt:ssh 
60298 3618K ACCEPT     tcp  --  any    any     network/21           anywhere

3. try condor_status or condor_status -direct <node1>:4080 from node2
  
Actual results:

Without -direct it provides no output:
$condor_status
$

With -direct it provides error message like this:
$condor_status -direct <hostname>:4080
Error: communication error
SECMAN:2007:Failed to end classad message.
Error: Failed to contact startd <hostname>:4080 at <IP:4080>

At same time:
==> /var/log/condor/SharedPortLog <==
04/07/11 08:25:33 Calling Handler <DaemonCore::HandleReqSocketHandler> (2)
04/07/11 08:25:33 Return from Handler <DaemonCore::HandleReqSocketHandler> 0.0002s


Expected results:
just works

Additional info:
I'm also using settings to allow all connections to avoid issues with permissions:

ALLOW_WRITE = *
ALLOW_READ = *
ALLOW_NEGOTIATOR = *
ALLOW_ADMINISTRATOR_READ = *
