  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:

    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
    Escape character is '^]'.

    Connection closed by foreign host.

    Failure to connect typically looks like:

    dp_server:/etc> telnet box27 5555
    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 and out test box is

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

tcpdump -vvv -s0 -l src or dst
Connection closed by foreign host.
dp_server:/var/opt/omni/log> telnet 5555
Connected to
Escape character is '^]'.
Connection closed by foreign host.

On client side:

root@box01:/opt/omni/newconfig/var # tcpdump -vvv -s0 -l src or dst
tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes
14:16:11.399557 IP (tos 0x0, ttl  63, id 37125, offset 0, flags [DF], proto 6, length: 48) > S [tcp sum ok] 108858745:108858745(0) win 32768  
14:16:11.414013 IP (tos 0x0, ttl  63, id 37126, offset 0, flags [DF], proto 6, length: 40) > . [tcp sum ok] 108858746:108858746(0) ack 773015701 win 32768

14:16:11.436864 IP (tos 0x0, ttl  63, id 37128, offset 0, flags [DF], proto 6, length: 40) > F [tcp sum ok] 0:0(0) ack 2 win 0

[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 # service iptables status
Firewall is stopped.
# /opt/omni/lbin/inet inet -log /var/opt/omni/log/inet.log
