Even worse, this breaks the JtR test suite.
The test suite is located in a test subdir at the same level as run and src.
(bleeding-jumbo)run $ cd ../test/
(master)test $ ./jtrts.pl -type cisco8 -v -stoponerror
-------------------------------------------------------------------------------
- JtR-TestSuite (jtrts). Version 1.13, Dec 21, 2014. By, Jim Fougeron &
others
- Testing: John the Ripper password cracker, version
1.8.0.4-jumbo-1-bleeding_omp [linux-gnu 64-bit AVX-autoconf]
--------------------------------------------------------------------------------
John Jumbo build detected.
--pot=NAME option is valid
--encoding=NAME option is valid
all.chr (../run/all.chr) not found
alnum.chr found, inc_alnum_ee8763c850dee8e4b88ef547a8ed39b8 added as a
capability
Types to filter on:
cisco8
Capabilities in this build of john:
jumbo core inc local_pot_valid encode_valid utf8 cp1252 cp1251 koi8r
cp437 cp737 cp850 cp858 cp866 iso8859-1 iso8859-15
inc_alnum_ee8763c850dee8e4b88ef547a8ed39b8
form=cisco8 guesses: 0 -show= 0 unk unk :
Expected count(s) (1500) [!!!FAILED2!!! exited, return code 1]
Exiting on error. The .pot file ./tst.pot contains the found data
The command used to run this test was:
../run/john -ses=./tst -pot=./tst.pot cisco8_tst.in
--wordlist=pw-70.dic -form=pbkdf2-hmac-sha256
(master)test $ ../run/john -ses=./tst -pot=./tst.pot cisco8_tst.in
--wordlist=pw-70.dic -form=pbkdf2-hmac-sha256
Invalid session name: must not contain a dot
In this case, jtrts.pl uses --session=./tst to make sure the .rec and
.log files remain in the test subdir, even if the john binary is located
in ../run/.
So, dots in the path name should be allowed.
