Dell OMSA: how to enable SNMP on Debian

This worked for me with Debian Lenny on a PE 2900. Reposting, since it took a bit of digging to find it. Credit to Bas Roos

--------------------------------------------------------------------------------------

* apt-get install snmpd
* Edit /etc/snmp/snmpd.conf
- Comment out 'com2sec paranoid default public
- Uncomment out '#com2sec readonly default public'
- Change 'default' into our management IP range in the previous
step (resulting in 'com2sec readonly 192.168.2.0/24 public')
* Edit /etc/default/snmpd
- Change SNMPDOPTS
- Before: SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux
-p /var/run/snmpd.pid 127.0.0.1'
- After: SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -p
/var/run/snmpd.pid 0.0.0.0' (this enabled smux and made snmpd listen on
all interfaces, instead of lo)
* /etc/init.d/dataeng enablesnmp (this should enable SNMP for both dataeng
itself, as it adds a line to /etc/snmp/snmpd.conf)
* /etc/init.d/dataeng restart (restarts dataeng and starts dsm_sa_snmp32d)
* /etc/init.d/snmpd restart

After this, SNMP seems to be working:
username at mgmt-server:~$ snmpwalk -v 2c -c public 192.168.2.71
.1.3.6.1.4.1.674.10892.1.300.10.1.11.1
SNMPv2-SMI::enterprises.674.10892.1.300.10.1.11.1 = STRING: "
here>"
