Bug 25243 – Mirrorselect 0.6 problems

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Narada Sage 2003-07-25 04:05:08 UTC]

$ mirrorselect -a -s4
Downloading a list of mirrors...
Running netselect to determine mirrors, this might take a moment...
netselect: unknown host ftp6.uni-erlangen.de
netselect: unknown host ftp6.uni-erlangen.de
No mirrors have been selected. Exiting.

$ mirrorselect -v
Mirrorselect version: 0.6

This happens everytime.  It complains about unknown hosts and then after a while
exits.  It exits without setting mirrors even when there is no error about
unknown hosts.

for the record, I had this same problem even with 0.5 every once in a while.  It seemed to happen when I was using a lot of my bandwidth up (not all of it, just enough to slow things down).

[Comment 2 Narada Sage 2003-07-26 03:25:15 UTC]

Depending on and using netselect makes mirrorselect slower, bulkier and more error prone.  Perhaps interactive mode should be the only mode of working.  That will be faster, better distributed geographically and less likely to cause problems.  Just a thought.

[Comment 3 John Mylchreest (RETIRED) 2003-07-26 03:37:27 UTC]

automatic mode is an optional mode, and by no means is ideal. it does have a few drawbacks, although all problems I currently know about will have a fix in the next release of mirrorselect.

They are nearly always related to routing, dns, or other similar problems.
it should still return a list, and those errors imo arent whats stopping it, some routers prevent 40+ requests all at the samew time, so mirrorselect will in furture split it into blocks of 5 at a time, where possible.

[Comment 4 Dan 2003-07-31 09:10:50 UTC]

The splitting up into 5 requests is a good one.  I have yet to have mirrorselect work in automatic mode for the past several versions.  I'll be anxious to try it when it's ready.

mirrorselect-0.7 has now been comitted to portage testing.
this contains a block-select update to allow it to bypass routers which block over a certain number of simultaneous(sp?) lookups. (appears to not select anything if you run -a -s4)

Please test away if this effects you.
