Proof authentification error

sthoeba · March 2, 2005, 5:19pm

Hi, i’m trying to launch Proof but i have some problems during the authentification (so it seems to me…).
I can start root, but when i launch proof :
[color=red]gROOT->Proof(“localhost”) [/color]
i get the following errors.
[color=red]
Error in : server does not accept the requested authentication
method from this host or from user@host
Error in TSlave::TSlave: UidGid authentication failed for host localhost
Error in TProof::Init: failed to connect to a PROOF master server[/color]
I configured everything as written in the file PROOF.README. I’m actually using one machine as master and slave at the same time. And i have set the the proof.conf file.
where could i find the error?
thank you very much in advance.

Dear Sthoeba,

Could you please specify which version of ROOT you are using?

Anyhow, your problem seems to be related to proofd access control list:
try adding the following line either to $ROOTSYS/etc/rpdauth.allow or
to $ROOTSYS/etc/system.rootdaemorc (depending on the version …):

localhost 5

If it still does not work, please do the following:

run proofd in the foreground in a separate window, starting it with the command:
proofd -d 3 -f -p 5555
in your ROOT seesion start PROOF with
gROOT->Proof(“localhost:5555”)
Send the log messages you get from the proofd window

Thanks for your response.
I’m using ROOT 3.10, could it be a problem related to the version?
i found neither rpdauth.allow nor system.rootdaemorc…
should i change the version?

Thanks again

Dear Stefano & Barbara,

I am sorry, the previous name for the access control file was $ROOTSYS/etc/daemon.access (not rpdauth.allow). Can you find it?

About upgrading: that’s always advised, if not too complicated.
You are probably using development version 3.10/01 which was issued in the middle of several changes happening in this part of the code.

Hello Stefano & Barbara,

I don’t know what authentication method you prefer, but I suggest UsrPwd.
To set this write in daemon.access the line:

default 0

So every host you use can be authenticated by Username/Password.
It’s possible to pu this file in your $HOME directory, but I don’t know if you must rename it here
(to .daemonaccess or something like that).

The file system.rootrc can also be copied into your $HOME dir and renamed into .rootrc.
In this file you can change the authentication methods for the client and the authentication process can be defined.

UsrPwd.Login: (uour username)

To be prompted for login information

UsrPwd.LoginPrompt: no

To reuse established security context

#UsrPwd.ReUse: yes

To control password encryption for UsrPwd authentication

UsrPwd.Crypt: yes

If you need more support just write a note.

Cheers Carsten.
