hello,
a question to all rooters and network gurus,
i create a root file on an AIX machine (4.3, xlC) and ship the
root file to a linux (suse6.4) via nfs. when i then re-read this file on the
linux side, i often get a non deterministic error :
------ Event:137259
------ Event:137260
------ Event:137261
R__unzip: discrepancy with initial size
Error in <TBasket::ReadBasketBuffers>: fObjlen = 112932, nout = 0
if you re-run the program it occures that the error massage is at a different
event. some files work some don't.
after a lot of frustration and agony (5 days) i found, that this is (probably)
a network problem. shipping the file via nfs from aix to linux does not work.
cp'ing it to linux (siting on the linux machine) works if i correctly mount the
system (mount -t nfs 11.11.11.11:/from /to). ftp seems to work always. so somehow
i have the feeling that the linux-dir is not mounted correctly on the aix.
can anybody help?
// ----------
i then tryed to use the rootdeamon. i believe that for people like me, where the sys-add
is on vacation it may be interesting to expand the statement:
compile rootd with -DR__SHADOWPW (see $ROOTSYS/rootd/Module.mk)
from : http://root.cern.ch/cgi-bin/print_hit_bold.pl/root/NetFile.html?rootd#first_hit
to:
a) compile root as always
b) rm .../rootd/src/*.o
c) rm .../bin.rootd
e) un-comment: SHADOWFLAGS := -DR__SHADOWPW
d) gamke
e) gmake install
f) then change /etc/services and /etc/inetd.conf as in the manual
(correct??)
i now can write files from one machine to the other, but i am a bit confused about
the statement(s):
1.Setting it globally via the static TAuthenticate functions TAuthenticate::SetUser() and
TAuthenticate::SetPasswd()
http://root.cern.ch/cgi-bin/print_hit_bold.pl/root/roottalk/roottalk01/0143.html?h2root#first_hit
2. setting it globally via TNetFile::SetUser(), TNetFile::SetPasswd() (manual)
both seem neither to exist, nor do i see how to use them, since an attempt to open a NetFile
immediately gives you the interactive login statements. (?)
can somebody explain to me how to use a TNetFile in a compiled program?
have fun,
martin s-w
