[rds-devel] problems with rds-tools

[Or Gerlitz]

Hi,

I am using rds-tools-1.0-20 over OFED 1.3 beta (i.e the tools package that
came with it) and have problems running rds-sink/gen. It seems that -gen
program:

1) refuses to work with the buffer size -b option

2) when attempting to use message size -m > 66k there is a "message too long" error.
Is this a known limitation, am I missing something re the buffer size option?

3) when using the -f option to rds-gen I get "Unexpected end of file reading from" error.
Again, is it a known issue?

The problems were initially reported by Ronen Ben Cohen <ronenb at voltaire.com>

Or.
