'''To [[SystemAdministration/Systems|Systems Overview]]''' ---- = Systems - Sun4 = = Basics = == Purpose == Sun4 is a host machine that runs OpenSuSE 11 and a number of Xen virtual servers. == Physical Location == This system is located in rack 3.7 in BIT-2B. == Physical Configuration == See [[SystemAdministration/EquipmentList]] == Logical location == * IP: 172.28.50.14 sun4.intra.cacert.org == Applicable Documentation == This is it :-) == Administration == System Admin: * Dirk Astrath = Services = == Listening services == || port || service || access origin || purpose || || 22 || SSH || [[SystemAdministration/Systems/hopper|hopper]] || SSH access for remote administration || To be completed. == Running services == || Service || Started from || || cron || /etc/init.d/cron || || syslog-ng || /etc/init.d/syslog-ng || || ssh || /etc/init.d/ssh || || ntp || /etc/init.d/ntp || To be completed. == Other services == To be completed. == Connected Systems == Connected to all its virtual servers: 1.

[[SystemAdministration/Systems/Ns|ns]] === Outbound network connections === * Uses DNS resolver at 172.28.50.1 * NTP to tt0.ripe.net. * Firewall rules /etc/firewall.sh = Security = == Non-distribution packages and modifications == == Risk assessments on critical packages == = Tasks = == Xen server navigation == 1. list Xen servers - sudo xm list 1. grab Xen server console - sudo xm console {machine} == where are the Xen server configurations == * less /etc/xen/vm/* == building Xen servers == * to be supplied = Critical Configuration items = == Start == After a statrt of this server it's not possible to enter the crypto-password for the harddisk using the ILOM/ELOM-textconsole. To enter this password, you need to use the "Remote Console", which can be started using Admin-Web-Environment. Unfortunately this web-environment is not working with recent browsers and java implementations. In detail: * Install Firefox 40 ... as this still works with the old cipher suites ILOM/ELOM-web-interface is able to present. * Install JRE 1.7.0_80 ... as this still works with the old cipher suites ILOM/ELOM-web-interface is able to present. * This Java-Installation needs to 32 bit ... as the Remote Console is able to use 32 bit only * Don't forget to install necessary libs in your Linux-set for 32 bit (or use a 32 bit distribution) * Forwarding the SSL-Port of ILOM/ELOM-web-interface to "other" ports will not work * Use an english keyboard to enter the crypto-password If the environment is set up, login via Firefox, start Remote Console and open the *.jnlp-file using /bin/javaws. == Firewall == * /etc/firewall.sh - Firewall configuration To be completed. = Changes = == Planned == === Document Backups === ---- CategorySystems
