Terabit speed for SDN?

Friday, May 29th, 2015

The US government has asked for terabit speed over optical for SDN.  Just a little feeling of “whoa” especially since I remember thinking a  1200 baud modem was the epitome of networking speed.  Amazing times in computing…..

Cygwin sshd multiple user access.

Monday, May 4th, 2015

Some of our development groups like to use SSH.  Especially, if they have a Linux background and were tossed into the windows world.

The basic configuration does work.  However, it’s for the main user running the sshd.

The documentation will tell you to have the user run ssh-config-user.  However, it’s not enough as you will be tormented by messages of /bin/bash not allowed and the connection dropping right after password entry.

Certain authority rights have to be established for the main account to allow other users to access the box.  Try the following:

  • editrights -l -u <local or domain/user>
  • editrights -a SeAssignPrimaryTokenPrivilege -u <local or domain/user>
  • editrights -a SeCreateTokenPrivilege -u <local or domain/user>
  • editrights -a SeTcbPrivilege -u <local or domain/user>
  • editrights -a SeServiceLogonRight -u <local or domain/user>
  • editrights -l -u <local or domain/user>

Restart you cygwin service and you should be able to ssh from any box.
