FreeBSD 11.3 p7 /amd 64
rsync version 3.1.3 protocol version 31
Copyright (C) 1996-2018 by Andrew Tridgell, Wayne Davison, and others.
Web site: http://rsync.samba.org/
Capabilities:
64-bit files, 32-bit inums, 64-bit timestamps, 64-bit long ints,
socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace,
append, ACLs, xattrs, iconv, symtimes, no prealloc, file-flags
In an attempt to get a list of updated files, I am using the option:
--info=name --out-format=%n
This works well some of the time. Unfortunately, there are some mirrors
that do not support the "--info=name" option, and exit with a error
code of 10.
EXAMPLE:
rsync: on remote machine: --info=NAME: unknown option
rsync error: requested action not supported (code 4) at
clientserver.c(839) [sender=3.0.6] rsync: read error: Connection reset
by peer (54) rsync error: error in socket IO (code 10) at io.c(785)
[Receiver=3.1.3]
Since this does not happen on all of the mirror sites, I would like a
way to get a list or have rsync display the IP of the site it received
an error message from and a way to block the use of that IP in the
future. Is that possible?
The complete set of options I am sending to rsync is this, if it
matters.
"--no-motd --quiet --times --compress --update --no-dirs --info=name
--out-format=%n"
Thanks!

If you instead want it to cycle between multiple IPs, you could use a simple caching DNS setup via dnsmasq. This software has a very simple override method where you specify a "addn-hosts=/file/name" line in its config file and then put multiple /etc/hosts style lines into it (since dnsmasq will add all the "IP DOMAIN" lines into a multi-IP result for that DOMAIN, unlike the normal local resolver which just picks the first IP). You'd just need to be sure to configure your localhost DNS lookups to use dnsmasq, which can be as simple as adding a "nameserver 127.0.0.1" line at the start of your /etc/resolve.conf file in front of your other nameserver line(s) (since dnsmasq skips a leading localhost nameserver line for its forwarded requests while local lookups use the first line in preference to the others). An alternative config option would be to add "alias" directives into the dnsmasq config where you tell it to replace a bad IP with a known-good IP. ..wayne.. -------------- next part -------------- An HTML attachment was scrubbed...
