If trapd/nvevent gets confused about the type of data in the varbind, I have seen it dump values like the email below shows.  It would be my guess it is getting escaped because the SNMP definition for that trap is not correct.

What's in the display window of nvevents is a construction. nvevents has already set aside a buffer and interpreted it.  What you are passing to your script is raw data from trapd.

If it contains blanks, then you must enclose it in quotes, just as you would any other script input on the command line.    You have to pass
        <myscript>  "$3"  
not just
        <myscript> $3
or the shell will pass only the first word of $3.

In general it doesn't hurt to enclose all of your variables
        <myscript> "$1" "$2" "$3" "$4" "$5"
when you don't know what form the incoming data will take.

AIX 4.3.3 ML10 + NV 7.1.3 + popular patches.

I need to provide a script with the parameters found in a trap.

$1, $2, etc work fine for integers and strings but doesn't for Octet Strings.

It seems that the bytes are passed (and escaped for most of them) by ovactiond.

Is there is way to get the bytes string as displayed in the events window ?

( i.e. a string like "0x01 12 34 ab ..." )

Best regards,
