openssh 4.3 on IRIX 5.3

Dear developers,

OpenSSH 4.3 (both p1 and p2) has a number of issues on IRIX 5.3 which  
were not present with 4.2p1:

configure thinks that a number of header files are unusable. This is  
because in order to use them other headers such as sys/types.h must  
be included as well, and configure's test code does not do so.

This can be worked around by setting ac_cv_header_sys_prctl_h=yes  
ac_cv_header_sys_dir_h=yes ac_cv_header_netinet_in_systm_h=yes  
ac_cv_header_net_if_h=yes ac_cv_header_lastlog_h=yes  
ac_cv_header_ia_h=yes


Nevertheless this still does not make a difference about the  
following annoying problem:


lorenz 149% ./ssh -v kobe
OpenSSH_4.3p1, OpenSSL 0.9.7i 14 Oct 2005
ssh: kobe: no address associated with name

the following works:

lorenz 150% ./ssh -v 192.168.0.1
OpenSSH_4.3p1, OpenSSL 0.9.7i 14 Oct 2005
debug1: Connecting to 192.168.0.1 [192.168.0.1] port 22.

Using 4.3p2 does not make any difference.

as do things on the same machine with OpenSSH 4.2p1:

lorenz 159% ./ssh -v kobe
OpenSSH_4.2p1, OpenSSL 0.9.7i 14 Oct 2005
debug1: Connecting to kobe [192.168.0.1] port 22.



There seems to be a problem with DNS resolution with 4.3p1 and p2.
Do you have any idea what is going wrong? Can you suggest what I  
should test or look for?
Is there a means to try step by step the changes included from 4.2p1  
to 4.3p1? Thanks.


Georg

Many of these have been fixed after the 4.3p2 release.  Could you please 
try the latest snapshot and let us know if any still occur?

A couple of things to try:

1) manually move "-lresolv" to the end of the LIBS in Makefile.  At 
least one other system (Reliant Unix) exhibits a similar problem and 
this is the workaround.

2) Define BROKEN_GETADDRINFO in config.h (if it's not already).

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
