The latest stable client for AIX 5.3 doesn't seem to contain aklog in it - http://openafs.org/dl/openafs/1.4.7/aix-5.3/rs_aix53.tar.gz Oddly the AIX 5.2 release has aklog. Trying compiling 1.4.7 from source under AIX 5.3 gave various errors (as mentioned in several earlier posts). Does anyone know a way to get a working aklog for AIX 5.3, as well as a working openafs client? Thanks!
