Thanks for your tip. At first I couldn't find where the 127.0.0.1 was
coming from on Etch, but after some digging around I found
/etc/defaults/snmpd (I always forget this folder)
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid
127.0.0.1' (this is SNMPDOPTS='-Lsd -Lf /dev/null -p
/var/run/snmpd.pid' on sarge)

I cut off the 127.0.0.1 bit, and it goes better now. Although no
errors, I also get no output on Sarge from Etch:
sarge:/# snmpwalk -v 1 -c public 192.168.1.36 system
End of MIB

So i tried something more specific on Etch:
etch:/# snmpget -v 1 -c public localhost system.sysUpTime.0
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: DISMAN-EVENT-MIB::sysUpTimeInstance

Yet on Sarge I get:
sarge:/# snmpget -v 1 -c public localhost system.sysUpTime.0
SNMPv2-MIB::sysUpTime.0 = Timeticks: (3251425) 9:01:54.25

Both sarge and etch have no specific (or default) snmp.conf, and should
get (?) their MIBs from /usr/share/snmp/mibs/ which look similar on
both hosts. Any ideas?
