My pc runs Scientific Linux release 6.8 (Carbon),
Kernel 2.6.32-642.3.1.el6.i686,
all patches applied.
After unpacking, running ' -/configure '
(just that, no other params), then
' make; make install DESTDIR=`pwd`/DESTDIR '
and running sshd from there: the call
' DESTDIR/.../bin/ssh host102 '
succeeds ( authentication with id_rsa ; host 102 is localhost
where the new sshd runs).
But running ' ./configure --with-ssh1 ' in a fresh
unpacked openssh-7.3p1 directory,
then the same as above: the sshd starts,
but calling the ssh does not succeed.
I see the following:
sshd:
/Data/openssh-7.3p1/DESTDIR/usr/local/sbin/sshd -p 222 -f \n
DESTDIR/usr/local/etc/sshd_config
ssh:
./ssh -vvv -p 222 -F DESTDIR/usr/local/etc/ssh_config host102

incomplete message
Aug 2 17:36:03 host102 sshd[7455]: fatal: buffer_get_bignum: buffer \n
error
The code after line 1111 in sshd.c (buffer_get_bignum) seems to be not
adequate any more.
I suppose the error will also show up on Centos.
Best regards
