September 26th, 2021, posted in SolarisENABLE HTTPS ON ORACLE M SERIES SERVERS(XSCF)
September 4th, 2021, posted in SolarisIf you have not enabled https on your M series servers, this is how you enable it.
Description From Oracle :
Hypertext Transfer Protocol (HTTP) over an authenticated/encrypted connection allows you to use the XSCF web browser securely. This is called the HTTPS service. Authentication is provided with a certificate authority and private keys. To use the HTTPS service, you must enable it, and provide an optional port number. The default port is 443. To enable HTTPS service, use the sethttps command”
1) Login to your xscf of the server through ssh
Assuming you have already configured network on xscf and enable ssh. If not, you can login through console/console server, configure network interface on xscf and then you can proceed with further steps.

2) Once you are in xscf, check the status of https
XSCF> showhttps
HTTPS status: disabled
3) Generate a self signed certificate.
XSCF> sethttps -c selfsign US California Irvine mycompany [email protected]
CA key and CA cert already exist. Do you still wish to update? [y|n] :y
Enter passphrase:
Verifying – Enter passphrase:
4) Check the HTTPS Status

SSH ERROR No Hostkey Alg
July 18th, 2021, posted in SolarisDo not ever change the file permissions of rsa and dsa keys. I was working on troubleshooting some ssh issue and I decided to give read permissions to everyone on file /etc/ssh/ssh_host_rsa_key and the next thing I know I cant login to the server via ssh.
#ssh testbox01 no hostkey alg #ls -l /etc/ssh/ssh_host_rsa_key -rw——-. 1 root ssh_keys 1679 Nov 25 2014 ssh_host_rsa_key #ls -l /etc/ssh/ssh_host_dsa_key -rw——- 1 root root 668 Aug 20 2007 /etc/ssh/ssh_host_dsa_key #ls -l /etc/ssh/ssh_host_rsa_key.pub
-rw-r–r–. 1 root root 382 Nov 25 2014 ssh_host_rsa_key.pub
#ls -l /etc/ssh/ssh_host_dsa_key.pub -rw-r–r–. 1 root root 382 Nov 25 2014 ssh_host_dsa_key.pub
Make sure the permissions are set to 0600 for the private ssh keys and 0644 for public ssh keys(default public keys under /etc/ssh ends with an extension .pub)
