Trying to build OpenSSH-2.1.0 on HP-UX 10.20

Wed May 10 19:31:44 EST 2000

Hi,

I just tried building of OpenSSH-2.1.0 on HP-UX 10.20 and found the following
items:

- The configure command I used at the beginning:
CC=cc CFLAGS="-Ae +O2 +DAportable" CPPFLAGS="-I/usr/local/include -I/usr/local/s
sl/include -I/usr/include/X11R6" LDFLAGS="-L/usr/local/lib -L/usr/local/ssl/lib
-L/usr/lib/X11R6" ./configure --prefix=/usr/local/openssh --sysconfdir=/etc/ssh
--with-rsh=/usr/local/lib/rsh/remsh --with-tcp-wrappers --with-pid-dir=/var/run
--with-xauth=/usr/bin/X11/xauth --with-ssl-dir=/usr/local/ssl

- Regardless if specified via "--with-ssl-dir" or not, /usr/local/ssl/include
  is not searched for include files.
  From config.log:
  ...
configure:2003: checking for OpenSSL directory
configure:2051: cc -o conftest -Ae +O2 +DAportable -Aa -D_HPUX_SOURCE -I/usr/loc
al/include -I/usr/local/include -I/usr/local/ssl/include -I/usr/include/X11R6 -L
/usr/local/lib -L/usr/local/ssl/lib -L/usr/lib/X11R6 -L/usr/local/lib conftest.c
 -lz  -lcrypto 1>&5
cc: "configure", line 2046: warning 604: Pointers are not assignment-compatible.
cc: "configure", line 2046: warning 563: Argument #2 is not the correct type.
cc: "configure", line 2046: warning 604: Pointers are not assignment-compatible.
cc: "configure", line 2046: warning 563: Argument #3 is not the correct type.
  ...

  [This is why I added /usr/local/ssl/include to CPPFLAGS]

- Unlike typical "configure" operations, flags passed as CPPFLAGS are ignored
  during the actual build process.
cc -Ae +O2 +DAportable -Aa -D_HPUX_SOURCE -I/usr/local/include -DETCDIR=\"/etc/ssh\" -DSSH_PROGRAM=\"/usr/local/openssh/bin/ssh\" -DSSH_ASKPASS_DEFAULT=\"/usr/local/openssh/libexec/ssh/ssh-askpass\" -DHAVE_CONFIG_H   -c -o bsd-misc.o bsd-misc.c
cpp: "rsa.h", line 21: error 4036: Can't open include file 'openssl/bn.h'.
cpp: "rsa.h", line 22: error 4036: Can't open include file 'openssl/rsa.h'.

cpp: "cipher.h", line 21: error 4036: Can't open include file 'openssl/rc4.h'.

cpp: "bsd-misc.c", line 50: error 4036: Can't open include file 'openssl/rand.h'.
  -> workaround: move CPPFLAGS into CFLAGS

- The "-Aa -D_HPUX_SOURCE" hardcoded does not efficiently use the HP-UX
  environment. "-Ae" does include the above flags _and_ "+e" for 64bit
  long long support (as the -Aa overrides the CFLAGS given):
configure:2267: checking size of long long int
configure:2286: cc -o conftest -Ae +O2 +DAportable -Aa -D_HPUX_SOURCE -I/usr/local/include -I/usr/local/include -I/usr/local/ssl/include -I/usr/include/X11R6 -L/usr/local/lib -L/usr/local/ssl/lib -L/usr/lib/X11R6 -L/usr/local/lib conftest.c -lz  -lcrypto 1>&5
cc: "configure", line 2281: error 1681: Must use +e or -Ae for long long in ANSI
 mode.
configure: failed program was:
...

- The documentation says:
  --with-pid-dir=PATH specifies the directory in which the ssh.pid file is
  created.
  * ssh.pid != sshd.pid perfect, it won't interfere with my running
    ssh-1.2.27 :-)
  * At the end of the compilation:
    -D/var/run/sshd.pid=/var/run/sshd.pid
    Ok, lets reconfigure it to another path :-(

- make install gives:
/opt/imake/bin/install -c -d /usr/local/openssh/bin
rm: /usr/local/openssh/bin/ directory
cp: illegal option -- d
Usage:  cp [-f|-i] [-p] [-S] [-e warn|force|ignore] source_file target_file
        cp [-f|-i] [-p] [-S] [-e warn|force|ignore] source_file ... target_directory
        cp [-f|-i] [-p] [-S] -R|-r [-e warn|force|ignore] source_directory ... target_directory
...

- The INSTALL document (and probably others) have not yet fully integrated
  ssh2 support.

- First tests:
  openssh client -> ssh-1.2.27 server: works
  openssh client -> openssh-server [Proto 1]: works, but without X-forwarding
                    even though configured with "X11Forwarding yes"
                    [have not looked into it as of now]
  openssh client -> openssh-server [Proto 2]: does not work.

serv01 111: /usr/local/openssh/bin/ssh -2 -p 24 serv01
PRNG seedfile /home/aet/serv01/jaenicke/.ssh/prng_seed must be mode 0600, owned by uid 11019
serv01 112: ls -al ~/.ssh/prng_seed 
-rw-------   1 jaenicke   aet           1024 May 10 11:26 /home/aet/serv01/jaenicke/.ssh/prng_seed
                     [my $HOME and $HOME/.ssh are 700, too]
                     [Also no debugging until now]

- Please note, that the internal PRNG is a problem:
  * Startup takes quite a long time when calling an ssh client.
    [The server startup is also slow, but it does not happen too often]
  * The sshd server clobbers my syslog.log:

Puh, so much for my first experiences. Seems I will stay with sshd-1.2.27
for some more time while trying to track all of these items down...
