  • Re-created on January 13th, 2016 using kvmutil with nographics option. GNIS'd.

Notes for old Fedora 19 version

  • On November 23rd, 2015, Helmet was moved along with zippy to the sixth floor ERI server room and its domain updated from geog.ucsb.edu to chg.ucsb.edu.
  • On October 7th, 2015 issues with Helmet's autofs and firewall were discovered. Helmet was restarted and autofs regained functionality, but due to the sustained vulnerability of the firewall and multiple failed logins it was decided (by Libby and Aaron) on October 14th, 2015 that it would be best if Helmet was completely redone. Shrad will review Helmet for any relevant configuration files and before it is taken down and redone.
    • Until new Helmet VM is done, I have added iptables functionality and disabled firewalld per the instructions on the ERI wiki CentOS 7 page. Libby 11:09, 15 October 2015 (PDT)
#Added alias sc="systemctl" to root's .bash_profile
#Short version, one line command:
yum -y install iptables-services ; sc stop firewalld ; sc mask firewalld ; sc start iptables ; sc enable iptables ; sc disable firewalld
#Long Version
systemctl stop firewalld     # stop firewalld temporarily
systemctl mask firewalld    # not sure what mask does, but I assume its similar to disable

yum install iptables-services  # install iptables-services package
systemctl enable iptables    # Enable the service at boot-time
#Copy over any rules you want iptables to start with since no defaults are provided (copied from chg-ewx,  minus web rules)
systemctl start iptables     # start iptables
service iptables save   # save iptables rules in /etc/sysconfig/iptables, overwriting current set
