Hi, i was using rsync 2.4.5 for AIX 4.3 binary downloaded from http://rsync.samba.org/ftp/rsync/binaries/AIX/ . I now compiled the latest 2.5.6 on AIX 4.3.3 and created a tarball to use like the one available from http://rsync.samba.org/ftp/rsync/binaries/AIX/ . root@b50srv1:/usr/local/src# uname -a AIX b50srv1 3 4 000B14FD4C00 root@b50srv1:/usr/local/src# oslevel 4.3.3.0 root@b50srv1:/usr/local/src# gcc -v Reading specs from /usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.2.0/2.95.3/specs gcc version 2.95.3 20010315 (release) root@b50srv1:/usr/local/src# cd rsync-2.5.6 root@b50srv1:/usr/local/src/rsync-2.5.6# ./configure root@b50srv1:/usr/local/src/rsync-2.5.6# make root@b50srv1:/usr/local/src/rsync-2.5.6# cd .. root@b50srv1:/usr/local/src# mkdir -p man/man1,man/man5,bin} root@b50srv1:/usr/local/src# mkdir -p man/man5 root@b50srv1:/usr/local/src# mkdir bin root@b50srv1:/usr/local/src# cp -p rsync-2.5.6/rsyncd.conf.5 man/man5/ root@b50srv1:/usr/local/src# cp -p rsync-2.5.6/rsync.1 man/man1/ root@b50srv1:/usr/local/src# cp -p rsync-2.5.6/rsync bin/ root@b50srv1:/usr/local/src# tar cvf rsync-2.5.6-AIX433.tar man bin root@b50srv1:/usr/local/src# gzip -9 rsync-2.5.6-AIX433.tar If someone would like to update the binary version available it's possible to download that on http://fabio.pietrosanti.it/rsync-2.5.6-AIX433.tar.gz .
