hex-array print

[joe.cipale]

I am using perl to write a acript that will retreive SNMP data and
possibly modify SNMP values for a given object on a switch.

If I retreive the SNMP data using the standard Net-SNMP command
(snmpget), the data I see is:Hex-STRING:FF FF FF F0 00 00 00

If, on the other hand, I use the SNMP package written in perl, the data
is sreturned as such: yyy0. I have tried to have the data stored as an
array (@hex_data) and attempted to access the data by walking through
it one character at a time with no luck

Any suggestions?

Thanks

Joe

The y's you are seeing probably have diacritical marks?

perldoc -f unpack

I think you mean ÿÿÿð.

pack() and unpack() were created for just such.

perl -le '$_="\xff\xff\xff\xf0"; print "$_ = ",unpack "H*",$_'
ÿÿÿð = fffffff0

Hi!

Another poster suggested pack()/unpack() as well. Another route I have
chosen, some a modicum of success is to downloand/install Net::SNMP,
which is a newer, updated version of the SNMP.pm package.

I will play with pack/unpack, as Net::SNMP places restrictions on what
I can/cant do.

Thanks for your help!

You're welcome.
