Hi, not sure if this is considered news, but I have been able to build OpenSSH 5.8p2 on mips-dec-ultrix4.5. On my system I have ULTRIX 4.5 with the latest Y2K patch kit as well as zlib-1.2.5, openssl-0.9.8m and prngd-0.9.29, several GNU utilities and gcc-3.0.4. To build openssh one has to check in various files if <sys/socket.h> and/or <netinet/ip.h> are multiply defined, because of "includes.h". edit config.h to #define BROKEN_READV_COMPARISON #undef HAVE_TYPE_IN_UTMP #define DISABLE_UTMPX #undef ENABLE_PKCS11 in ssh-keygen.c remove references to pkcs11_init and pkcs11_terminate on lines 1410 and 1493. to get sshd working one has to either set "UsePrivilegeSeparation no" or "Compression no" in sshd_config. I finally went with "Compression no". I hope this report is helpful for some people, although I am quite sure that the number of ULTRIX users out there is very, very small at best. Please CC: me if you want to reply, because I am not subscribed to this list. regards, Dennis ------------------- $ ssh -l root ttpux2 root at ttpux2's password: Last login: Mon Aug 22 05:02:55 2011 from 192.168.2.11 ULTRIX V4.5 (Rev. 47) System #3: Sat Jan 1 09:01:31 MET 2000 UWS V4.5 (Rev. 6) Digital Equipment Corporation Nashua, New Hampshire # bash root at ttpux2:/# uname -a ULTRIX ttpux2 4.5 0 RISC root at ttpux2:/# ssh -V OpenSSH_5.8p2, OpenSSL 0.9.8m 25 Feb 2010 root at ttpux2:/# telnet localhost 22 Trying 127.0.0.1...
