How to Fix Unison 6.2 VM's issue where lmhostid returns "" and not mac address

edit /etc/udev/rules.d/70-persistent-net.rules

it contains:

# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x8086:0x100f (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:aa:6d:77", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

just change NAME= to NAME="eth0", keep the rest as is.

edit /etc/sysconfig/network-scripts/ifcfg-eth0

it contains:

DEVICE="eth0"

BOOTPROTO="dhcp"

HWADDR="00:0C:29:AA:6D:77"

DOMAIN="ltx.com ltx-credence.com ltxc.com"

IPV6INIT="no"

IPV6_AUTOCONF="yes"

NM_CONTROLLED="no"

ONBOOT="yes"

TYPE="Ethernet"

make sure the HWADDR is set to correct mac address. you can get mac address from call to ifconfig

restart the system

How To Install Unison In CentOS

Instructions for extracting Evx releases and patches.

1.  If you do not have gnu tar and gzip, retrieve the files
    gnutar and gzip. By clicking the download link.
    

2. Retrieve the appropriate release. By clicking the download link. 

   

   NOTE: You will need approximately 500 Meg free on your machine
   to hold the file, and approximately 2 Gig to extract it.
   

3. Once the transfer is complete, you can extract the file.  You
   must use gnu tar to extract the file.  The directory nesting
   of an Evx release is too deep for most unix tars.
   Again, make sure you have at least 2 Gig free in the directory
   where you will be extracting the tar file.
   Assuming that gnutar, gzip and the downloaded archive are all
   in the same directory, run the following commands to extract the
   archive:

   Make gnutar and gzip executable
   # chmod 755 gnutar gzip

   Uncompress the archive
   # ./gzip -dc R12.2.0.gnutar.gz | ./gnutar xf -
   
   Uncompress command for R12.4.0 and above:
   # ./gzip -dc R12.4.0.gnutar.gz | ./gtar xf - 

   Uncompress command for Linux Example:
   # /bin/gzip -dc R15.4.0.i686_linux_2.6.9.gnutar.gz | /bin/gtar xf -

4. Once the archive has been extracted, you will find installation
   instructions in the doc directory

Understanding Loaded and Selected Sites in EVXA /EIM

ProgramControl.getNumberLoadedSites()
- returns the number of defined sites in Adapter Object of the test program + 1


ProgramControl.getNumberSelectedSites()
- returns the number of sites (selected or not selected in bin tool) from site 1 up to maximum site that is active (selected in bin tool) + 1
- say 4-site is [1101] where site 3 is inactive. return value is 5
- say 4-site is [1010] where sites 2 and 4 are inactive, return value is 4
- say 4-site is [0110] where sites 1 and 4 are inactive, return value is 4

- say 4-site is [0001] where sites 1, 2, and 3 are inactive, return value is 5

ProgramControl.getLoadedSites()

- returns a a pointer to an array of sites that are defined in Adapter Object of the test program

- site 1 is referenced to array [1] and array[0] does not really define a site
- the size of the array it points to is the return value of getNumberLoadedSites()

ProgramControl.getSelectedSites()

- returns a a pointer to an array of sites from site 1 to last site that is active (selected in bin tool)
- if no site is selected in bin tool, returns 0 ***

- site 1 is referenced to array [1] and array[0] does not really define a site
- the size of the array it points to is the return value of getNumberSelectedSites()
