SDN 101: An Introduction to Software Defined Networking
Discover the advantages of SDN.
SDN has quickly become one of the hottest trends in IT. But not all SDN solutions offer real software-defined functionality. As more enterprises consider SDN, they want to know, What is SDN? And what are the real benefits? If you're ready to explore the advantages of SDN, and want to know how it should be implemented within your enterprise, start by reading our introductory white paper.

I have two computers running Slackware 10.2 (Kernel 220.127.116.11, SMP Kernel on both computers), these are only connected to each other, so no connection to the internet or any other network. No "firewall" is up on both.
For several reasons i need rsh instead of ssh.
I have configured /etc/inetd.conf to allow rsh:
shell stream tcp nowait root /usr/sbin/tcpd in.rshd -L
login stream tcp nowait root /usr/sbin/tcpd in.rlogind
exec stream tcp nowait root /usr/sbin/tcpd in.rexecd
Then on both computers the same user is set with ~/.rhosts on both computers
Then /etc/hosts.equiv is set on both computers, as well as /etc/hosts.allow which looks like this:
(to allow all connections from all hosts)
Again this two computers are only connected to each other via a small 2 port switch.
But when i try rsh rcp etc.. i get
rcmd: socket: Permission denied.
Can anybody tell me what else i could do try etc.. to get it working?
Is there another config file etc...
~/.rhosts has permissions 600 and is owned by the correct user.
I have been testing around with the iBook later then and i found out that i can do a rsh from the iBook to both of the computers. Then i set up rsh on some old "Noname" Notebook where Slackware 10.2 is running and i can rsh from both "mainboxes" to the noname notebook. But when i try to rsh from one of the mainboxes to the other i still get
rcmd: socket: Permission denied.
Have you tried removing each of the two mainboxes from each other's /etc/host.equiv? I'm grasping at straws, but maybe stripping the problem down to the minimum number of variables might help. Remove hosts.equiv, remove .rhosts and see if you can login with a password.
I have removed ~/.rhosts and /etc/hosts.equiv on both boxes and i canīt login with a password either.
rcmd: socket: Permission denied is all i get...
Could it be that the package which contains rsh has a bug?
Also i donīt find a "newer" package than the one i have installed for Slackware 10.2
After some testing and playing around with it i guess there must be something wrong with the package i have installed, as other hosts expect the second Slackware-box can connect but the outgoing connections to other hosts just donīt work.
I try to get / install a newer version and see if that helps.
Hmm, i reinstalled the package and found out that i can do rsh -l username host as user root but if i try to do this as normal user i get Permission denied, then i checked the permissions for rsh and rlogin which are correct.
