Hello everyone,

I'm trying to get snow (snow_0.3-3) to work on two linux nodes: one 32-bit
ubuntu 10.04 and one 64-bit ubuntu 8.04 node:

> setDefaultClusterOptions(type="SOCK", homogeneous = FALSE, manual=FALSE,
outfile="/tmp/snowMaster.log")
> cl = makeCluster(c("ubie.lan"), type = "SOCK")
mark@ubie.lan's password:

Attaching package: 'snow'

The following object(s) are masked from 'package:base':

    enquote

> clusterApply(cl, 1:2, get("+"), 3)
[[1]]
[1] 4

[[2]]
[1] 5

> clusterApply(cl=cl, x=c(nrow=60,nrow=250), fun=coint.vector.clustered,
prices=prices, pairwise=F)
Error in checkForRemoteErrors(val) :
  2 nodes produced errors; first error: cannot open the connection

As you can see the first clusterApply() call works fine, but the second one
(which produces a real amount of data) fails every time with "cannot open
the connection".
Ssh works fine between both machines and and if use "localhost" in stead of
ubie.lan the workers complete successfully (also for the second
clusterApply() call).

Here is my sessionInfo() on the master machine:

Any idea what i'm doing wrong here?
