The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

problem setting alternate netmask in Solaris 10

Asked by con2007 in Unix Setup, Unix Networking, Sun Solaris

Tags: solaris, netmask, 10

For Solaris 10 (11/06) we are trying to create a netmask of 255.255.240.0 but cannot seem to get it to work.  Here is what is configured so far:

root@03# cat netmasks
#
# The netmasks file associates Internet Protocol (IP) address
# masks with IP network numbers.
#
#       network-number  netmask
#
# The term network-number refers to a number obtained from the Internet Network
# Information Center.
#
# Both the network-number and the netmasks are specified in
# "decimal dot" notation, e.g:
#
#               128.32.0.0 255.255.255.0
#
172.17.20.0     255.255.252.0
# Private
172.16.40.0     255.255.240.0
root@03#


e1000g5: flags=69040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER,STANDBY,INACTIVE> mtu 1500 index 5
        inet 172.16.40.11 netmask ffff0000 broadcast 172.16.255.255
        groupname grpports35
        ether 0:15:17:35:a3:1b
root@02#
root@02# cat /etc/hostname.e1000g5
172.16.40.11 netmask + broadcast + deprecated \
group grpports35 -failover standby up
root@02#


We've gone into the /etc/hostname.e1000g5 and modified the line to read:

172.16.40.11 netmask 255.255.240.0 broadcast + deprecated \
group grpports35 -failover standby up

and that worked, but this is not a supported method.  Changing it in netmasks should have done this - is there another file in Solaris 10 that we are not including?
