Sorry about thatthe box names are just first three initals of company with standard developers names

like:

xxxbox1
xxxbox2
xxxbox3

THe xxxbox1 one is our push server. From there we check all the rest!

Here is the output of the last code:

Code:

while read fname; do 
    bname=$(basename $fname) 
    echo "trying ${fname} (${bname})" >&2

    hash=$(/usr/local/bin/md5 "$fname" | awk '{print $4}')

    echo "local hash is ${hash}"

    # should just print the md5's
    /usr/local/bin/hosts | while read box
    do
        echo "${box}"
        # should print md5's repeatedly
        ssh ${box} "/usr/local/bin/md5" "$fname"
    done
done < /home/izivanov/iz3

And what the output is:

Quote:

xxxbox1(root):/home/izivanov# sh dirsync6.sh
trying /opt/dba/scp/xxxxxxxxxxxxx
local hash is xxxxxxxxxxxxxxxxxxxxxxx

~
~
~
local hash is xxxxxxxxxxxxxxxxxx
xxxbox3 /opt/dba/bin/xxxxxxxxxxxxxx differs!

We got a differ on one of the servers! Yeah something is definitely off! What do you need to see to have a better understanding!?

BTW we don't have md5sum ( we have md5), its an HP-UX environment. Isn't that only on the Linux type systems!?

did you get my message about what the host and hostname files look like and their output?

---------- Post updated at 02:56 PM ---------- Previous update was at 02:47 PM ----------

sorry the last code i actually used was:

Code:

#!/usr/bin/sh

# If you don't have mktemp, TMP=/tmp/$$ will do.  mktemp is more secure.
TMP=`mktemp`
while read fname; do
    #bname=$(basename $fname)
    echo "trying ${fname}" >&2

    if ! /usr/local/bin/md5 "$fname" > "$TMP" </dev/null
    then
        echo "md5 on ${bname} failed: "
        # print the error
        cat "$TMP"
        continue
    fi

    hash=$(awk '{print $4}' "$TMP")

    echo "local hash is ${hash}" >&2

    # should just print the md5's
    /usr/local/bin/hosts | while read box
    do
        # redirect its stdin to prevent it reading any filenames
        ssh "${box}" "/usr/local/bin/md5" "${fname}" > "$TMP" </dev/null

The only thing I added was #!/usr/bin/sh, cause my boss told me I would need it!

clmresidue

clm residue(1)							  USER COMMANDS 						    clm residue(1)

  NAME
      clm residue - extend clustering of subgraph to clustering of graph.

      clmresidue  is  not  in  actual fact a program. This manual page documents the behaviour and options of the clm program when invoked in mode
      residue. The options -h, --apropos, --version, -set, --nop are accessible in all clm modes. They are described in the clm manual page.

  SYNOPSIS
      clm residue -icl fname (input clustering) -imx fname (input graph) [-rpm fname (residue projection matrix)]  [-o	fname  (output	clustering
      file)]

  DESCRIPTION
      The cluster file presumably contains a clustering of a subgraph of the graph G contained by the matrix file, implying that the row domain of
      that clustering is a subset of the node domain of the graph. clm residue will compute  a	simple	upwards  projection  of  that  clustering,
      resulting in a clustering of G.

  OPTIONS
      -imx fname (input graph)

      -icl fname (input clustering)

      -rpm fname (residue projection matrix)
	The name for the file in which the residue projection matrix is stored.  It contains for each node and for each cluster in the input clus-
	tering the combined weight of the (edges to the) neighbours of that node in that cluster.  The default output file name is out.rpm.

      -o fname (output clustering file)
	The name for the file in which the majority vote projection clustering is stored. Aka the majority vote projection clustering storage file
	name.

	This  embodies	a very crude approach to distributing the missing nodes in the input clustering onto that same cluster. For each node, the
	cluster is taken for which the residue projection is the largest (see above). The residue (i.e. the set of  missing  nodes)  is  initially
	viewed	as  a  cluster;  the set of nodes for which the projection is largest for the residue itself will form a new cluster, if it is not
	empty.

	By default output is sent to STDOUT.
