And I cannot open it in any editor.
JFYI: This is what you can try, if the logfile is too big: - Execute 'grep main.cc /var/log/zypper.log' this will show you the 'Hi, me zypper..' lines followed by the command that was executed: 2011-06-09 14:37:26 <1> fibonacci(15841) \ [zypper] main.cc(main):75 ===== Hi, me zypper 1.6.9... 2011-06-09 14:37:26 <1> fibonacci(15841) \ [zypper] main.cc(main):76 ===== '/Local/ma/zypp/BUILD/zypper/src/zypper' \ 'up' 'fate' ===== - If you can identify the command that went wrong, look at the 'HOSTNAME(PID)' at the beginning of the line that shows the command. Here it's fibonacci(15841)' Then execute 'grep "fibonacci(15841)" /var/log/zypper.log >/tmp/my-zypper.log' /tmp/my-zypper.log will then contain the log of this zypper command only. - If you just know the date (like '2011-06-09') you can grep for all command of this day: 'grep "^2011-06-09" /var/log/zypper.log >/tmp/my-zypper.log' -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It does not WORKFORME because I'm again using IPV4. zypper on my local machine is also today able to access download.opensuse.org using it's IPV6 address [2001:67c:2178:8::13] and to retrieve data from there: (doGetFileCopyFile):1328 URL: http://download.opensuse.org/repositories/ zypp:/Head/openSUSE_11.4/repodata/repomd.xml.asc (log_curl):109 * About to connect() to download.opensuse.org port 80 (#0) (log_curl):109 * Trying 2001:67c:2178:8::13... (log_curl):109 * Connected to download.opensuse.org (2001:67c:2178:8::13) port 80 (#0) ... (log_curl):109 < Accept-Ranges: bytes (log_curl):109 < Content-Length: 189 ... (doGetFileCopy):1299 HTTP response: 200 So for me IPV6 basically works, and I do not know what caused the problem on your machine. It may very well be, the problem was not located on your machine at all, but somewhere between you and download.opensuse.org. So if you can provide the zypper log showing this error, I'll check whether it contains any hints to errors we can fix. But without further info I don't know what to do. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I cannot provide other logs than I provided. This means the problem is not reflected in the log.
It may very well be, the problem was not located on your machine at all, but somewhere between you and download.opensuse.org.
The only problem was that zypper tried to access download.opensuse.org via IPv6 when IPv6 was not available. As you can see fromn the zypper's output, it tries to connect only via IPv6 even though IPv4 was available. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

(should be 7.20 or above, 7.21.2 is what I'm using). - This is what I execute in one terminal to see how zypper(libcurl) connects: $ export ZYPP_MEDIA_CURL_DEBUG=2 $ tail -f /var/log/zypper.log | grep log_curl - In an other terminal I call 'zypper ref' for one of my repos and check how curl behaves: $ host download.opensuse.org download.opensuse.org has address 195.135.221.134 download.opensuse.org has IPv6 address 2001:67c:2178:8::13 $ zypper ref -f zypp:Head 2011-06-17 11:31:00 <1> fibonacci(15669) [zypp++] MediaCurl.cc(log_curl):109 \ * About to connect() to download.opensuse.org port 80 (#0) * Trying 2001:67c:2178:8::13... * connected ... ==> So curl per default connects using IPv6 $ ip route del ::/0 ==> deleting my IPv6 route $ zypper ref -f zypp:Head 2011-06-17 11:33:07 <1> fibonacci(15968) [zypp++] MediaCurl.cc(log_curl):109 \ * About to connect() to download.opensuse.org port 80 (#0) * Trying 195.135.221.134... * connected ==> So curl now falls back to using IPv4 $ ip route add ::/0 via ... ==> reenable IPv6 route $ zypper ref -f zypp:Head 011-06-17 11:35:11 <1> fibonacci(16435) [zypp++] MediaCurl.cc(log_curl):109 \ * About to connect() to download.opensuse.org port 80 (#0) * Trying 2001:67c:2178:8::13... * connected ==> back to IPv6 again And even if I mess up my route, so it does not fail on my host, but some hops apart: 2011-06-17 13:52:18 <1> fibonacci(22660) [zypp++] MediaCurl.cc(log_curl):109 \ * About to connect() to download.opensuse.org port 80 (#0) * Trying 2001:67c:2178:8::13... * No route to host * Trying 195.135.221.134... IPv6 does not succeed and curl falls back to v4. - I finally found just one way to reproduce the behavior you describe: In /etc/hosts explicitly enter just the v6 adress of download.opensuse.org: 2001:67c:2178:8::13 download.opensuse.org #195.135.221.134 download.opensuse.org In that case v4 is not considered as an /etc/hosts entry superseeds DNS. But if both addresses are present, as they should be, it again works. 2001:67c:2178:8::13 download.opensuse.org 195.135.221.134 download.opensuse.org Sorry, but I can't find a bug here. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
