Some Exadata defaults
Had some fun with an Exadata a few days ago, been waiting for a while to put my hands on one…”shoulder surfed” the root password during the installation because it appeared in clear text multiple times, the other ones where easy to guess, those IB switches still have the shadow file ugo+r .
Here are some default pwd and user combos:
root:welcome1 (dbserver, cell, ibsw)
nm2user:changeme (ibsw, read-only)
ilom-admin:ilom-admin(ibsw)
ilom-operator:ilom-operator(ibsw)
admin:admin(PDUs)
The SCSI storage over infiniband looks pretty awesome(40Gb), but i’ll have to wait for proper load testing to be made… ~800k for a bunch of x64 boxes (3 storage and 2 database boxes) and 2 inifiniband switches running Linux is a lot of cash…but hey…maybe it’s worth it…Now bring on one of those T4-4 Sparc SuperClusters

Our last post about geolocation is now deprecated since it now needs some api key to use the web service, the following script can be used after getting the key:

Windoze sucks!
ERROR
I know windoze sucks…it sucks even more when its a “hammered” version, probably full of nasty stuff and spits out something like this during the install process…I guess that version belongs in the trash with the rest of them…Besides, chances are one would quickly become part of some botnet just by using that shit.
Fast NAT with iptables
Here is a fast way to share our inet connection:
# iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
# iptables --append FORWARD --in-interface wlan0 -j ACCEPT
# echo 1 > /proc/sys/net/ipv4/ip_forward
