Description Patrick Ogenstad 2003-03-10 08:05:25 UTC

People are having problems doing a "emerge rsync" due to dns lookups for
rsync.gentoo.org.

Reproducible: Always
Steps to Reproduce:
1. emerge rsync
2. nslookup rsync.gentoo.org
3.

Actual Results:  
>>> starting rsync with rsync://rsync.gentoo.org/gentoo-portage...
rsync: getaddrinfo: rsync.gentoo.org 873: No address associated with hostname
rsync error: error in socket IO (code 10) at clientserver.c(83)
>>> Starting retry 1 of 3
rsync: getaddrinfo: rsync.gentoo.org 873: No address associated with hostname
rsync error: error in socket IO (code 10) at clientserver.c(83)
>>> Starting retry 2 of 3
rsync: getaddrinfo: rsync.gentoo.org 873: No address associated with hostname
rsync error: error in socket IO (code 10) at clientserver.c(83)
>>> Starting retry 3 of 3
rsync: getaddrinfo: rsync.gentoo.org 873: No address associated with hostname
rsync error: error in socket IO (code 10) at clientserver.c(83)



Take a look at the link to the forums and my post with subject "Lookup
problems", since many people are having this problem I think it should be fixed
by the gentoo.org's dns administrator.

The reasons for this are described here:

It's a limitation of DNS, not any problem with Gentoo or emerge.  The solution is to enable TCP/53 on your firewall.

We may look at trimming down the rsync round robin as a short term solution, but that is not a fix -- only a quick hack.  This is a larger issue that needs to be addressed on the client side, not the server side.
