testssl.sh is taking an educated guess which port makes sense to scan,
which one not and for which one to use which starttls handshake upfront.
This minimizes needless sscans and error messages.
Parallel mass testing mode is now not anymore experimental. To
use it a separate flag ``--mode=parallel`` was introduced. Serial
is still the default for now to avoid unexpected conditions.
Both the mode arguement and the default is subject to change.
The parallel mass testing mode can now also make use of a
nmap file. Also the functional test for nmap file was put
into a separate function and made more user safe. Open point is
that we better should use the hostname if the forward DNS record matches.
Fixed logical inconsistency: Ticketbleed was not being tested against a server with client authentication
Some variables in the beginning reordered
timeout: the TLS ticket check has a timeout, so that early on non-reachable hosts
are determined. If it is running into the timeout, it quits early. The
timeout is configurable via environment e.g. TIMEOUT=16 ./ticketbleed.bash <host>
Also other ports are allowed albeit it probably it is of limited use
Supplying no arg is now more user-friendly
Open issues: 1) The SNI logic 2) The fileout logic. 3) another section with ``trust_nosni -eq 4/8``
For 2): fileout is a general finding MEDIUM [1] which isn't in line now with the pr_*finding
in the section above anymore. It would make sense to punish HTTP services more than others.
Unfortunately he fileout statement cannot be moved below pr_svrty_medium/pr_svrty_high as
trustfinding_nosni hasn't been determined yet.
Fast solution would be probably to move the trustfinding_nosni section above the trustfinding
section.
Still 3) and a different trust over non-SNI makes it difficult -- e.g. Server has CN match only over
SNI but without SNI SAN matches. That's an edge case though which probably doesn't exist (like Bielefeld)
[1] That was WARN before. WARN should indicate a status of testssl that it cannot perform a check

started to use the ip parameter to decide where the dns resoultion
takes place (see #739 and #748). --ip=proxy or DNS_VIA_PROXY=true
will mean DNS resolutioni is done by proxy,
furthermore: swapped a few pr_magenta by pr_warning. Generally
testssl.sh should use for warnings a warning function and not
directly a color (we want to be flexible). There are still a few
remainders for fatal() which use bold magenta and thus I haven't
changed yet.
Also html_reserved() is being called also if no html output
is being requested. This could be fixed better probably.
was received, testssl.sh tries 3 times to get memory from the server, If
the server returns different memory it's highly likely vulnerable.
(some more vulnerable devices to test against would be appreciated).
This is the default now -- all other hosts are mostly labled as OK.
Parsing SERVICE should be a little faster and more reliable
Increased needed debug level for output @ parse_tls_serverhello
Sometimes it just does not. In those case also sometimes session resumption
via tickets is supported.
This fixes the output for Session Ticket RFC 5077 and doesn't draw the wrong
conclusion from a missing lifetime hint.
It also tests for ticketbleed first whether there's a session ticket TLS
extension.
