Hi,
I ran into the following behavior:
$ cat foo.txt | parallel --sshlogin $MYHOST --filter-hosts --dryrun echo {}
::: a b
parallel: This should not happen. You have found a bug.
Please contact <parallel@gnu.org> and include:
* The version number: 20161222
* The bugid: host check too many col0: devcronapp-02 IT IS POSSIBLE THAT
SOMEONE IS DOING SOMETHING NASTY!
* The command line being run
* The files being read (put the files on a webserver if they are big)
If you get the error on smaller/fewer files, please include those instead.
The file foo.txt is attached (trivial two lines). The variable $MYHOST in my
case is an SSH host alias which when I log in to it, reports:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
SHA256:vKymg/7J3Vux8K8/fYuS/gjCvyS93+xyEcpbfWR2Y5k.
Please contact your system administrator.
Add correct host key in /home/jeldering/.ssh/known_hosts to get rid of this
message.
...
I realize that this is something I should fix, and I don't know whether this is
considered a bug in parallel, but just reporting it here. Let me know if
there's any other information else I can provide.
Best,
Jaap
