Opened: Apr 30, 2019

Severity: 3-Major

Symptoms

When tcpdump is invoked with the epva option on a non-epva platform (BIG-IP Virtual Edition, for example), it fails with an unclear message errbuf:DPT Provider fatal error. Provider:ePVA Provider. No valid arguments.

Impact

Unclear message does not give clear indication what the issue is, or how to get tcpdump to run with the 'all' option on non-epva platforms

Conditions

-- Using a non-epva platform such as VE. -- Calling the epva option: + Directly: tcpdump -i 0.0 --f5 epva + Indirectly using 'all' (which includes epva): tcpdump -i 0.0 --f5 all

Workaround

Do not use the explicit epva option on non-epva platforms (it does not work anyway, as there is no epva debug information on those platforms). Instead of 'all', explicitly specify other, non-epva providers on such platforms, for example, specifying 'noise' and 'ssl' providers: tcpdump -i 0.0 --f5 n,ssl

Fix Information

None
