there a way to find out what exactly is running, an IDS or IPS, and
accordingly is there a way to bypass these systems

If the IDS uses pcap (tcpdump et al) then you might find a way to crash
the IDS.  It seems that new IDS-crashing spoits come up often enough that
perhaps your customer isn't completely up to date.  Linuxsecurity.com has
a decent article on testing IDS systems here:
