Dear Rooters
I would like to open a root file as TNetFile on my local machine,
a PowerBook running LinuxPPC.
I did the following:
In one terminal I started rootd with: rootd -p 1094
In the second terminal I started root:
[christian@cookiebook rt]$ root

CINT/ROOT C/C++ Interpreter version 5.15.32, Feb 10 2002
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0] TFile *f =
TFile::Open("root://localhost:1094/test.root","READ")
Name (localhost:christian): christian
Password:
Error in <Authenticate>: wrong passwd
Error in <TNetFile::TNetFile>: authentication failed for host localhost
root [1] TFile *f =
TFile::Open("root://cookiebook:1094/rt/test.root","READ")
Warning in <TClass::TClass>: no dictionary for class TTestA is available
root [2] f.ls()
TFile** /home/christian/rt/test.root
TFile* /home/christian/rt/test.root
KEY: TTree TestA;1 CS
root [3] f.Print()
TFile: name=/home/christian/rt/test.root, title=, option=READ*
...etc...
As you can see I tried two different options:
In the first case: TFile::Open("root://localhost:1094/test.root","READ")
rootd asks for a username and password, but does not accept my password.
In the second case:
TFile::Open("root://cookiebook:1094/rt/test.root","READ")
root opens the file as a simple TFile but not as TNetFile,
as can be seen from f.Print().
My question now is:
How can I open a file as TNetFile?
What is wrong in the first case, that rootd does not accept my password?
Why does root open the file as TFile only in the second case?
Thank you very much in advance.
Best regards
Christian
