When I try to access my newly built server via webmin on the LAN I can only do so over http. When I try to do this over https I get an errmsg saying that the connection was interrupted. Any ideas as to what I need to do to enable https? Thanks in advance folks for any assistance you can offer.

Your post made me look at my own installation of Webmin. I was using only http: as well. If you go to Webmin-->Webmin Configuration-->SSL Encryption I generated SSL keys and stored them. Once done, I was prompted if I wanted to swith now, I said yes, I was dropped in http: mode, and had to sign in https: That was it...

BTW, I also took the time to limit the IP addresses Webmin will listen to. (under IP Access Control). Since my boxes are on a 192.168.x.x private network, I limited the IP addresses to that, plus localhost.

Hope this helps.

Many thanks Cliff, I 'll give that a bash later today when I get home
