Miscellaneous Notes

This is for internal use of lab administrators only

• Ldap: dhcp1 and dhcp2 (cname ldap1.orbit-lab.org) - The ldap conf lives in etc, as well as the "secret"
• Web: served out of external3 (cname www.orbit-lab.org) - External web huhah only.
• Internal ldap admin: ​http://internal4/phpldapadmin - If you just point a web browser to internal 3, it enumerates /, but that directory doesn't show up. however point the url directly works.
• Internal1 hosts the mysql services, but the phpmyadmin runs on internal3 (​http://internal4/phpmyadmin) (similar to the ldapamdin). You'll have to point the myadmin to internal1 to get the tables from that host (e.g. inventory).
• To get to internal pages, you now need to ssh from gw.orbit to syslog, which is an alias for internal4

Modifying inventory entries through XML

In this example I am trying to change a node from CM type 1 to type 10, the same process is true for any XML modifications to inventory changes. Changes can be done in a web browser opened in the internal1 network.

1. Check CM type and port

   internal1.orbit-lab.org:5054/inventory/attribute_list?set=nodeX-Y.DOMAIN.orbit-lab.org
   

2. Set new CM type

   internal1.orbit-lab.org:5054/inventory/attribute_modify?name=nodeX-Y.DOMAIN.orbit-lab.org&attribute=CM_type&value=10
   

3. Set new CM port

   internal1.orbit-lab.org:5054/inventory/attribute_modify?name=nodeX-Y.DOIMAIN.orbit-lab.org&attribute=CM_port&value=1
   

4. Restart the service

   /etc/init.d/omf-aggmgr-5.4 restart
   

Fixing IRQ issue on Gs with intel WIMAX and ath9k

1. Go into BIOS → Others → SIO configuration
2. Set 'Paraller' Port address to 'Disable'
3. Save and exit

Test by:

1. load baseline
2. ifconfig -a , make sure no wireless interfaces show (need to blacklist intel wireless)
   1. if intel wireless appears, rmmod iwlwifi
3. modprobe ath9k
4. check dmesg to see if radio comes up
5. check ifconfig -a to see if interface appears
6. ifconfig wlan1 up
7. iwlist wlan1 scan
8. iwconfig wlan1 essid WINMAIN

LV-67K issues

1. Go into BIOS → Others → SIO configuration
2. Set 'Paraller' Port address to 'Disable'

In BIOS, make sure management engine (ME) is set to enabled. otherwise, Ks will label eth0 and eth1 in wrong order, depending on details of pxe boot.
