Dear Sirs, Apologies if this is not the correct way to submit a question (my first to the list).
I am working with snmptrap - as bundled with net-snmp-5.4.1, and compiled for execution on a ppc_8xx. Wondering what the correct form is for specifying an IPv6 source (agent-address) within an snmptrap command line? The trap will be issued to the target host IP address (2005:0000:0000:0000:0148:0036:0051:0001) when I let the agent specify the agent-address with "" - for example see further below. In this case the trap is well received at the destination; but unfortunately I need to specify an IPv6 address rather than the IPv4 address it defaults to use. I have tried several forms (see below), but they all give the "unknown host" error (see example). Any suggestions would be appreciated.
