Segmentation Fault while compiling and installing openssh-3.9p1
I am trying to compile and install openssh-3.9p1 (with openssl-0.9.7j)
on my personal dev env to have a play. I get the below mentioned
segmentation fault message.
---------
Generating public/private rsa1 key pair.
/bin/sh: line 1: 10901 Segmentation fault ./ssh-keygen -t rsa1 -f
/home/vinay/var/vinay_ssh/etc/ssh_host_key -N ""

My configure and install script looks something like this
./configure --with-libs=-ldl --includedir=$HOME/var/vinay_ssh/include
--prefix=$HOME/var/vinay_ssh --exec_prefix=$HOME/var/vinay_ssh
--with-ssl-dir=$HOME/var/openssl
make clean
make install

Can someone shed light on why could the segmentation fault be generated
?

I certainly wouldn't. If you're reporting a bug in OpenSSH, you could at least do everyone the courtesy of trying with the latest version, to ensure that it's not a bug that's already been fixed in the last five years, and thus a complete waste of time to investigate and fix again. Also you did not provide nearly enough information about your platform, nor a debugger backtrace of the segmentation fault.

Does openssl's self-test ("make test") pass? How about with current versions of both? -- Darren Tucker (dtucker at zip.com.au) GPG key 8FF4FA69 / D9A3 86E9 7EEE AF4B B2D4 37C9 C982 80C7 8FF4 FA69 Good judgement comes with experience. Unfortunately, the experience usually comes from bad judgement.
