Review: grammar, spelling. Errorneous and obsolete description.
Some items reordered.
Updated: to reflect the current capabilities.
Moreover: (Almost) complete the tuning variables section.
As a kind of a pre-warning this commit allows the n-1 connection problem to
give feedback on the screen (that wasn't working before).
Also the message on the screen is now more clear and the manpage
gives better advice.
Related to #1172
The cipher suites names in the RFCs stem (mostly) from IANA, see
https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-4
This PR corrects that in places visible to the user. For backwards
compatibility the cmd line switches still work as before, but there's
a preference to IANA. The RFC naming is labeled as to be retired
in the future.
As mentioned in #1106 proxying ocsp protocol doesn't work (yet)
This commit notifies the user that it is not possible. One
can ignore that and try by supplying IGN_OCSP_PROXY=true.
It also fixes a typo I probably introduced (pVULN_THRESHLD).
The standard separator after $FNAME_PREFIX is now '-'.
You can as well supply a different <fname_prefix> ending in '.', '_' or ',' , then
no no additional '-' will be appended.
Also a small bash function get_last_char() has been introduced which returns
the last char from a supplied string.
... previously it depended on the order of DNS replies otherwise. This was
one outcome of discussion in #1026 where it seemed more logical
to pick an IPv6 address as opposed to an abitrary (v4/v6) address.
Reduce the offensive tests to 4: the others are "just" / mostly cipher
based checks which should not cause an IDS to block. (This maybe
subject to reconsider at a later time.)
Added a switch --ids-friendly
Updated VULN_COUNT accordingly
Added this (including PHONE_OUT to env debugging output)
Added help()
Manual section added
This PR changes the logic the no-DNS switch works. The switch
now expects a value. "min" does minimum lookups, "none" does
no lookups at all (details see testssl.sh(1) ). "none" is
equivalent to the paranoid (boolean) value "true" before.
See previous commit
This commit finally fixes#1005 so that either a --ssl-native scan
terminates on the next (defined) occasion if there are network connectivity
problems. It introduces another set of variables (MAX_OSSL_FAIL vs. NR_OSSL_FAIL).
As "openssl s_client connect" is sometimes still being used without --ssl-native
it also shortens the wait for regular scans if an outage is encountered.
To make things easier bot sets (incl. *_SOCKET_FAIL) of variables are independent.
For the seldom case that somebody uses --ssl-native with client checks an exception
had to be made as otherwise only MAX_OSSL_FAIL client check would be performed.
This hasn't been understood yet...
As sometimes HTTP header requests (over OpenSSL) fail repeatedly in a way that an empty
reply is returned, the same strategy of detecting problems is applied here,
using MAX_HEADER_FAIL and NR_HEADER_FAIL.
All three detection mechanisims share a new function connectivity_problem().
