Ok, this is not strictly a PostgreSQL issue, but I am trying to enable WAL log shipping on our PostgreSQL 8.1.10 (upgrade to 8.3.7 is in the works). My archive_command is 'rsync %p postgres@node2:/file/to/$f </dev/null' This works fine only if and only if SE Linux is disabled on node 1 (the source node). I am running Fedora Core 6 on node 1. (Upgrade to CentOS 5.2 is in the works.) I used audit2allow on the SELinux messages, and generated an SE Linux module to allow Postgres to rsync the files out... allow postgresql_t ssh_exec_t:file { read execute execute_no_trans }; allow postgresql_t ssh_port_t:tcp_socket name_connect; allow postgresql_t user_home_t:dir { search getattr }; allow postgresql_t user_home_t:file { read getattr }; But this still does now work. (Works fine if I disable SELinux, by the way.) The error I get is: LOG: archive command "/usr/local/bin/rsync -e /usr/bin/ssh pg_xlog/000000010000001D00000015 postgres@node2:WAL/000000010000001D00000015 </dev/null" failed: return code 65280 Could not create directory '/home/postgres/.ssh'. Host key verification failed. rsync: connection unexpectedly closed (0 bytes received so far) [sender] rsync error: unexplained error (code 255) at io.c(632) [sender=3.0.4] If anybody has any clue as to whats going on here, I would sure appreciate your help. "ssh node2" works fine from node1, I log in using key-based authentication What stumps me is there are no further complaints from SELinux, but clearly SELinux is blocking the connection. I think I'll ask on the SELinux list as well. But if anybody here has a clue, please give me a shout.
