Data Protector Troubleshooting

1. Check if firewall is running and enabled. Check if SElinux is enabled in RHEL.  Temporary disable both to exclude both factors.
   1. Look at chkconfig --list
   2. Check if service is running, for example
      • for Red Hat  service iptables status
      • for Syse service SuSEfirewall2_init status
2. Try manually start /opt/omni/lbin/inet and see the messages (sometime, especially if automated installation using tarball was use,  you have 64 bit client installed on 32 bit box):

    /opt/omni/lbin/inet -log /var/opt/omni/log/inet.log

3. Check if anything was written to /var/opt/omni/log/inet.log
4. Check omni service configuration.

   Two points to check:

   • Option disable   should be "no"
   • It TCPv6 is enabled OMNI puts the flag IPV6 in /etc/xinetd.d/omni:

   For example:

   service omni
   {
       socket_type         = stream
       protocol            = tcp
       wait                = no
       user                = root
       server              = /opt/omni/lbin/inet
       server_args         = inet -log /var/opt/omni/log/inet.log
       disable             = no
       flags               = IPV6 -- wrong
       instances           = UNLIMITED
       per_source          = UNLIMITED
   }

5. Check /etc/var/messages. Here for example when 64 bit client was installed on 32 bit Linux:

   Sep 11 13:51:32 box01 xinetd[31612]: execv( /opt/omni/lbin/inet ) failed: Exec format error (errno = 8)
   

6. Check if xinetd is listening of port 5555

   netstat -an |grep 5555 
   telnet localhost 5555

7. Connect from your DP server. If connection to port 5555 is OK you see

   Connected to box27.firma.com.
   Escape character is '^]'.

   Connection closed by foreign host.

   Failure to connect typically looks like:

   dp_server:/etc> telnet box27 5555
   Trying...
   telnet: Unable to connect to remote host: Connection refused
   dp_server:/etc> telnet box27 5555

8. Check DP agent logs, especially the date of the last record written.

   Logs location: /var/opt/omni/log  Actually /var/opt/omni contains a count of symlinks that provide that data of client installation: 

   DP logs location: /var/opt/omni/log

   There are two logs:

   -rw-rw-rw- 1 root sys     9692 Jun  6 13:06 debug.log
   -rw-rw-rw- 1 root root 1810920 Jun 27 13:13 inet.log

   Datastamp on inet.log actually are telling something about when last interaction with the server occurred.

9. Increase debug level of /opt/omni/lbin/inet

   service omni
   {
       socket_type         = stream
       protocol            = tcp
       wait                = no
       user                = root
       server              = /opt/omni/lbin/inet
       server_args         = inet -log /var/opt/omni/log/inet.log -debug 1-140 DBG_01.txt
       disable             = no
       instances           = UNLIMITED
       per_source          = UNLIMITED
   }

   Save the file and run the

   service xinetd restart

   command to apply the changes.

Getting TCP dump

Let's assume that out server is dp_server.firma.com and out test box is box01.firma.com.

On Server side open two windows. One for tcpdump, the other for telnet command.

tcpdump -vvv -s0 -l src or dst nti01.firma.com

Connection closed by foreign host.
dp_server:/var/opt/omni/log> telnet box01.firma.com 5555
Trying...
Connected to box01.firma.com.
Escape character is '^]'.
Connection closed by foreign host.

On client side:

root@box01:/opt/omni/newconfig/var # tcpdump -vvv -s0 -l src or dst dp_server.firma.com
tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes

[Sep 11, 2012] HP Communities - Impossible to telnet port 5555 - Enterprise Business Community

01-10-2007 05:10 AM

What is the service that is running in the port 5555, is it data protector?

If you run

netstat -an |grep 5555

Do you see the port in the LISTEN state?

Try stopping the firewall if any:

/opt/omni
/opt/omni # service iptables status
Firewall is stopped.

# /opt/omni/lbin/inet inet -log /var/opt/omni/log/inet.log
