Networker connecting to host failed: remote system error- No connection could be made because the target machine actively refused it

Thank you for looking into the issue.when i am executing  # /etc/init.d/networker start getting below error /etc/init.d/networker: line 47: /opt/nsr/admin/nsr_envexec: No such file or directory

OK, now we know daemons are not started

I really can't say much about 9.2 as it is new fresh and I didn't test it so I will look back to 9.1.0.x example and you can compare it.

I suspect function start_service() fails... here is how it looks on 9.1.0.x:

start_service() {         (echo 'starting NetWorker daemons:') > /dev/console         if [ -x /opt/nsr/admin/nsr_serverrc ]; then                 . /opt/nsr/admin/nsr_serverrc || exit 1         fi         if [ -f /usr/sbin/nsrexecd ]; then                 if [ -f /usr/sbin/NetWorker.clustersvr ]; then                         if [ -d /nsr.NetWorker.local -o \                             -h /nsr.NetWorker.local ]; then                                 if [ -h /nsr ]; then                                         rm -f /nsr                                         ln -s /nsr.NetWorker.local /nsr                                 fi                         fi                 fi                 "$NSR_ENVEXEC" -u "$NSRRC" -s "$NETWORKERRC" \                         "/usr/sbin/nsrexecd" 2>&1 | /usr/bin/tee /dev/console                 (echo ' nsrexecd') > /dev/console         if [ -x /usr/sbin/nsrpsd ]; then                 /usr/sbin/nsrpsd -i         fi         fi         if [ -f /usr/sbin/lgtolmd ]; then                 "$NSR_ENVEXEC" -s "$NETWORKERRC" \                         /usr/sbin/lgtolmd -p /nsr/lic -n 1 2>&1 | \                         /usr/bin/tee /dev/console                 (echo ' lgtolmd') > /dev/console         fi         if [ -f /usr/sbin/nsrctld -a \             ! -f /usr/sbin/NetWorker.clustersvr ]; then                "$NSR_ENVEXEC" -u "$NSRRC" -s "$NETWORKERRC" \                         "/usr/sbin/nsrctld" 2>&1 | /usr/bin/tee /dev/console                 (echo ' nsrctld') > /dev/console         fi         if [ -f /opt/nsr/nsrmq/bin/nsrmqd ]; then                 "$NSR_ENVEXEC" -s "$NETWORKERRC" \                         /opt/nsr/nsrmq/bin/nsrmqd --config=/opt/nsr/nsrmq/nsrmq.cfg \                         --pidfile=/opt/nsr/nsrmq/nsrmq.pid \                         --logfile=/opt/nsr/nsrmq/logs/nsrmq.log 2>&1 | \                         /usr/bin/tee /dev/console                 (echo ' nsrmqd') > /dev/console         fi         if [ -d /var/lock/subsys ]; then                 touch /var/lock/subsys/networker         fi }

The bold line is line 47 and it seems like this might be the same.  Somewhere before that there is definition and comment that reads as following:

# IMPORTANT NOTE: # Upgrading NetWorker will overwrite this startup script. # End-users should place NetWorker environment variables in nsrrc, which will # be sourced before starting NetWorker daemons. nsrrc must be a Bourne shell # script, and environment variables in nsrrc must be exported to take effect. NSRRC=/nsr/nsrrc NSR_ENVEXEC=/opt/nsr/admin/nsr_envexec # networkerrc defines environment variables, such as LD_LIBRARY_PATH, required # to run NetWorker daemons. NETWORKERRC=/opt/nsr/admin/networkerrc

In your case it seems like /opt/nsr/admin/nsr_envexec is not there.  Try to find it first... for example "find / -name nsr_envexec -print".

In my case it is /opt/nsr/admin/nsr_envexec as defined by script (same is defined in your script).  My best guess from seen so far is that this script is missing on your system.  Not sure if this is bug with installation or something else (one would need to check rpm).  In my case (but I do not know if this is compatible with 9.2 code base) this looks as following:

I understand that this is a message from a remote client (not the NW server itself).

It means that the communication between both clients is fine (by default they communicate via ports 7937 & 7938) -

however 'the connection has actively been refused'.

Usually it will be generated if the NW server is not allowed to access the client - the client will refuse the access.

How does NW control that? - via the file /nsr/res/servers. It should contain each allowed NW server - one per line.

So edit the file appropriately (it might contain a typo) or delete it (careful - in this case you would allow all NW servers to access the client).

Whenever you make a change to the file you must restart the NW daemon on the NW client to activate the change.

BTW - run 'nsr_render_log /nsr/logs/daemon.raw' on the client - it should tell you more.

can you paste the output of the client name

From Networker server can you run

nsrrpcinfo -p
