[gentoo-user] emerge sync

[Cédric FINANCE]

Hello,

    I have some trouble when I try to sync the portage tree. It works
fine when I try by a friend in a wire network. At home, I have a
wireless network and a treeway adsl modem. When I execute the emerge
sync, it starts to download some files but everytime, it stops after 272
files.

As every try it downloads files, if I try two or three times the sync is
completed. Can I do this without being blacklisted ? Have I to only use
emerge-webrsync ? Does somebody have a clue about why the rsync fails
after 272 files downloaded?

Cédric

This seems to indicate that the server you are trying to sync with 
hasn't responded in 180 seconds. How is the quality of you wireless 
connection?

The Link quality is not supported by the driver (ndiswrapper). I am 
connected to an irc server and I have no problems. I don't think that 
the problem come from the wireless connection. It might have something 
to do with the rsync protocol, the modem or my ISP. But I don't know how 
to figure out where the problem is.

Have you tried emerge-webrsync instead of emerge sync?

irc as in chatting?  irc hardly does anything to stress your hardware!!

No?  Some network cards work fine until you pass large amounts of data
through them, at which point they fall over and in some cases crash the
entire system.  It's often a driver problem - I've seen it many times.

only inasmuch as the rsync protocl stresses your network card.

do you have a LAN as well? You could try that out.  Otherwise I would
look for an alternative .inf file to use with ndiswrapper (from windows
NT instead of windows XP for example), or look for a native linux driver
for your network card.

The only time I've seen this has been if the link has gone down or if 
the rsync server is under heavy load (i.e. if I run an emerge on my 
server and try to sync against it at the same time).

Try and download a big file with ftp and see how the throughput is. 
This should show if it's a modem/ISP problem or a rsync one.

Btw when I first got my wireless it constantly lost connection ( 5 
connected 1 not connected, 5 seconds connected...) but that was solved 
by changing the channel for the wireless link.

I fetched vmware-workstation and got 180kB/s.

It doesn't seems that I lose the connection to the access point.
What's strange is that the rsync always stop after 272 files downloaded
even during the 3 retries.

My wireless card is a Dlink 510 ( or 610) . The chipset is a rtl8180 with
pciids changed. I use the windows rtl8180 driver (the driver from dlink
is buggy: uses all cpu when access point unreachable). There is a native
driver in portage (rtl8180) but I didn't manage to make it work : can't
connect to the access point and it floods syslog. I'll try to rsync without
my wireless card.

Downloading a single file isn't necessarily going to do the same "stress
test" as an rsync trying to download 100000+ files...

Is it always with the same rsync server or have you tried different
ones?

Also, someone mentioned the channel, did you check your AP and card are
using the same channel? (This may be a long shot...)

Did you try a different driver for ndiswrapper?  Did you try the same
rsync server with a different card?  I know you don't think its the
card, but I would still rule it out if I could.

I don't know what else to suggest - if its the rsync server then don't
use it!  If not, then try playing around with different hardware /
drivers until you isolate the problem...

hi

why emerge sync is sometime very long, at the step update portage cache,
sometime it takes 1mn and sometime lot longer ?

Portage problem. Will be better next release I hear. Search the forums and
search the newsgroup for portage, metadata, cache for more info. Most
often, hangs at 50-51% while redoing KDE. Defrag or moving /usr/portage to
its own partition has been known to help. Read some of the posts.

My experience has been that defraging /usr/portage brought enormous
speed up, but just once or twice.  Soon after the darn thing slowed down
again.  Looking forward to the next portage version.  :-)
