Hallo, 

I am trying to install a setup like shown below 

ZEO_M 
 | -- ZEO_B
 |     | -- ZOPE
 |     | -- ZOPE
 |     | -- ZOPE
 |     ...
 | -- ZOPE
 | -- ZOPE 
 ...

The ZEO_B should be a zeoclient of the ZEO_M (MainZEO). The reason for
this setup ist that the ZEO_B is located in a backup computing center on 
the other side of our campus.

When I configured the ZEO_B as a zeoclient of the ZEO_M. I comes up 
without problem. I've connected the first client, the connection is 
establisched but the server never come up. 

Here is the log from ZEO_B level debug

I started it with runzope and killed it with CRTL-c. I had it once waiting for 
2 hours without any difference. 

here is the ZEO_B config file 

# ZEO configuration file

%define INSTANCE /data/zope/zeoproxy01

<zeo>
  address 8110
  read-only false
  invalidation-queue-size 100
  # pid-filename $INSTANCE/var/ZEO.pid
  # monitor-address PORT
  # transaction-timeout SECONDS
</zeo>

<zeoclient main>
  server 10.152.64.1:8100
  storage main
  name main
#  var $INSTANCE/var
#  client zeoproxy01
#  cache-size 600MB
</zeoclient>

<eventlog>
  level debug
  <logfile>
    path $INSTANCE/log/zeo.log
  </logfile>
</eventlog>

<runner>
  program $INSTANCE/bin/runzeo
  socket-name $INSTANCE/etc/zeo.zdsock
  daemon true
  forever false
  backoff-limit 10
  exit-codes 0, 2
  directory $INSTANCE
  default-to-interactive true
  # user zope
  python /usr/local/bin/python
  zdrun /usr/local/www/Zope28/lib/python/zdaemon/zdrun.py

  # This logfile should match the one in the zeo.conf file.
  # It is used by zdctl's logtail command, zdrun/zdctl doesn't write it.
  logfile $INSTANCE/log/zeo.log
</runner>

The Zope Server directly on ZEO_M works without problems.
