Useful Links

• nvram - change or display non-volatile RAM variables

  e.g.nvram to display all settings, nvram Autoload Y to change autoload parameter

• xlv_mgr - manage and display XLV volumes, can be used in interactive mode, e.g.
  • xlv_mgr - takes you into interactive mode
  • xlv_mgr> show all - displays current set up
  • xlv_mgr> show object db1 - shows volume db1 details
  • xlv_mgr> delete object db1 - deletes volume db1

• /etc/default/login - Controls direct root access. To change, uncomment CONSOLE and define where allowed to login straight as root

• hinv - gives information about disks with SCSI ID and controller number

• prtvtoc - disk details (what is on the disk)

  e.g. prtvtoc dkssndcnvh where sn is the SCSI ID and cn is the controller number as shown in hinv

  Gives type i.e. xfs - logical volume (if no mount directory it isn't mounted!), raw - raw partition; volhdr header; volume whole volume; start address and size

• swap -l - gives swap details. Part of this is the major and minor numbers. From this by doing ls -l /dev/dsk/dksndns* can tell where swap is allocated to

• sysinfo - gives serial number for some servers (otherwise on back of box!)

• osview - performance monitoring tool (GUI version called gr_osview)

Networking

• /etc/hosts - hosts/IP addresses
• /etc/sys_id - hostname of server
• /etc/config/netif.options - network card parameters . If these options are changed should execute /etc/autoconfig and reboot
• /etc/config/ifconfig-1.options - controls netmask and settings used by ifconfig at startup (network scripts are /etc/init.d/network and /etc/init.d/network.local)
• netstat -r - check router statements
• ifconfig interface - check interface card up and configured
• netstat -ina - check interface name

Assigning more IP addresses to a network card

1. Edit /etc/config/ipaliases.option adding entries as required (network card name can be found from netstat -r, netmask and IP info from ifconfig)

2. run chkconfig - if ipaliases not shown do chkconfig -f iplaliases on

3. run /etc/init.d/aliases_ip

4. check with ifconfig

Xwindow Security

• xhost - controls which displays can be brought up on which workstations. By itself with no options it displays current settings
• xhost hostname - allow displays from hostname to come up on current workstation
• xhost - hostname - remove permission
