Bug ID: 13207 Summary: rsyncd doesn't send output of failed pre-xfer exec script to client Product: rsync Version: 3.1.1 Hardware: x64 OS: Linux Status: NEW Severity: normal Priority: P5 Component: core Assignee: way...@samba.org Reporter: d...@dana.is QA Contact: rsync...@samba.org Hello, The rsyncd.conf documentation says: >If the pre-xfer exec command fails, the transfer is aborted before it begins. >Any output from the script on stdout (up to several KB) will be displayed to >the user when aborting, but is NOT displayed if the script returns success. However, i can't actually get it to do this. In fact, i don't get any meaningful output at all. My pre-xfer script: #!/bin/sh echo $RSYNC_HOST_ADDR return 1 My rsyncd.conf: [testing] path = /home/dana read only = true pre-xfer exec = /home/dana/rsync.sh The client command and its output: % rsync -vvvv --debug=all 172.17.66.1::testing/foo . opening tcp connection to 172.17.66.1 port 873 sending daemon args: --server --sender -vvvve.LsfxC --debug=ALL . testing/foo (6 args) (Client) Protocol versions: remote=31, negotiated=31 rsync: read error: Connection reset by peer (54) rsync error: error in socket IO (code 10) at io.c(785) [Receiver=3.1.2] [Receiver] _exit_cleanup(code=10, file=io.c, line=785): about to call exit(10) The rsyncd log output: 2018-01-09 12:25:45 rsyncd[7770]: connect from myhostname (172.17.66.100) 2018-01-09 12:25:45 rsyncd[7770]: rsync on testing/foo from myhostname (172.17.66.100) 2018-01-09 12:25:45 rsyncd[7770]: pre-xfer exec returned failure (256): 2018-01-09 12:25:45 rsyncd[7770]: 172.17.66.100 2018-01-09 12:25:46 rsyncd[7770]: rsync error: requested action not supported (code 4) at clientserver.c(973) [sender=3.1.1] As you can see, i get the script output in the log — but not on the client side. The server side is running rsync 3.1.1 on Ubuntu 16.04. I have tried launching `rsync --daemon` manually, just to make sure that systemd wasn't interfering with the I/O somehow, and it did the same thing. The client side is running rsync 3.1.2 on macOS 10.12. I also tested 3.1.1 from the same machine as the server and again got the same result. Am i doing something wrong? Is there some prerequisite for seeing this output? (If so, it might be helpful to mention it in the documentation.)
