Hi all,
I have two computers, both dual core, so I thought I could make use of proof, but I ran into troubles when I tried to make the authentication work …
OK, so here is what I’ve done:
- proof.conf containes:
[code]master hefr42
worker hefr42
worker hefr42
worker hebook09
worker hebook09[/code]
and it is the same on both computers
- xpd.cf :
[code]###
Example of simple xrootd config file.
The first part enables a simple data server exposing to clients
the root paths /tmp and /data1.
The second part shows how to enable password-based strong
authentication using the ROOT special password in $HOME/.rootdpass
The third part shows how to concurrently enable the PROOF serving
features
To load this configuration file:
~> xrootd -c $ROOTSYS/etc/proof/xpd.cf
See http://www.slac.stanford.edu/xrootd for more details on the
data serving part.
Part one: data serving
xrd.protocol xrootd *
xrootd.fslib libXrdOfs.so
Specify a non-default port here:
- overwritten by -p on the command line
xrd.port 5151
Export path directives, i.e. the root paths which can accessed
by clients (‘xrootd.export /’ exports the whole file system).
An arbitrary number of these can be defined. The default is
to export /tmp.
NB: specifying any of these directives removes the default /tmp
from the internal list; in such a case a directive needs to
be given explicitely if /tmp needs to be exposed.
xrootd.export /tmp
#xrootd.export /pool/data
Part two: security directives:
Example: enable password-based strong authentication checking
also the special ROOT password in $HOME/.rootdpass.
NB: if the application complains about a missing password file in
$HOME/.xrd/ just create an empty one running ‘xrdpwdadmin’ and
replying to the questions
(<ROOT_sys> with the path to the ROOT distribution)
xrootd.seclib /afs/physik.uni-freiburg.de/opt/root_v5.18_slc4_py2.4_dcache/lib/libXrdSec.so
sec.protocol pwd -d:3 -upwd:1
Part three: enable PROOF serving
Load the XrdProofd protocol:
a) if the ROOT lib paths are known by the linker/loader
#xrd.protocol xproofd:1093 libXrdProofd.so
b) using absolute paths (<ROOT_sys> with the path to the ROOT distribution)
xrd.protocol xproofd:1093 /afs/physik.uni-freiburg.de/opt/root_v5.18_slc4_py2.4_dcache/lib/libXrdProofd.so
NB: envs vars are not expanded here, i.e. $ROOTSYS/lib/libXrdProofd.so will
not work; they are supported for the remaining “xpd.” directives
Directives governing the behaviour of the XrdProofd plug-in.
Except when explicitely indicated, all the following directives support
an optional 'if ’ condition at the end of the line, e.g.
xpd.rootsys /opt/root if lxb*.cern.ch
xpd.rootsys /usr/local if lxp*.cern.ch
Patterns may contain any number of wild cards; the best match is retained
(max number of matching chars; if two are equal, the last specified wins).
Available ROOT versions: the first ‘rootsys’ defines the default one;
specifying a tag is optional: if missing, the ROOT version tag is taken
(however, the tag must be unique, the first occurence is retained).
If no ‘xpd.rootsys’ valid directives are specified, $ROOTSYS is used as
default ROOT version.
xpd.rootsys /afs/physik.uni-freiburg.de/opt/root_v5.18_slc4_py2.4_dcache [tag_for_default_version]
xpd.rootsys /opt/root-dev [tag_for_an_alternative_version]
Location of the temporary directory [/tmp]
xpd.tmp /usr/tmp
Internal wait timeout in secs [5]
xpd.intwait 500
Max number of PROOF sessions [-1, i.e. no limit]
xpd.maxsessions 10
Number of workers for local sessions [number of CPUs]
#xpd.localwrks 2
Multiuser option
Default 1 (==ON) when running as superuser, 0 (==OFF) when running as normal.
user. In the case the daemon has normal privileges, all users run under the
effective user starting the daemon and privacy of sandboxes is not ensured
xpd.multiuser 0
Defines what to do when no client sessions are attached to a client area.
Format:
xpd.shutdown
where:
is the type of action to be taken when a client completly
disconnets; the options are:
0 remain connected
1 terminate when idle
2 terminate no matter the processing state
is the delay after which the action for option 1 or 2
is performed; in seconds; to indicate minutes or hours use
the suffix ‘m’ or ‘h’, respectively; e.g. 5m for 5 minutes.
default:
xpd.shutdown 1 0
xpd.shutdown 1 1m
xpd.shutdown 1 1s
Image name of this server [node name]
xpd.image
Working directory for sessions [<User_Home>/proof]
If this directive is given, the user working directories will be in the
form <work_dir>/<user_name>
xpd.workdir /tmp/proofbox
Dataset root directory [<User_WorkDir>/dataset]
If this directive is given, the user dataset directories will be in the
form <dataset_dir>//, with =“default” if
does not belongs to any of the defined groups.
xpd.datasetdir <dataset_dir>
Max number of old PROOF sessions for which the working directory
is kept with all the relevant files in (logs, env, …); non-positive
values mean no limit [10]
xpd.maxoldlogs 10
Modify priority of sessions belonging to by <delta_priority>
If is missing, apply the change to all sessions.
This directive requires special privileges, so it may be ineffective
if these are missing
xpd.priority <delta_priority> [if ]
xpd.priority 4
xpd.priority 6 if thatuser
Resource finder
NB: 'if ’ not supported for this directive.
“static”, i.e. using a config file
<cfg_file> path alternative config file
[$ROOTSYS/proof/etc/proof.conf]
<user_cfg_opt> if “yes”: enable user private config files at
$HOME/.proof.conf or $HOME/.<usr_cfg>, where
<usr_cfg> is the second argument to
TProof::Open("","<usr_cfg>") [“no”]
<max_workers> Maximum number of workers to be assigned to user
session [-1, i.e. all]
<selection_mode> If <max_workers> != -1, specify the way workers
are chosen:
“roundrobin” round-robin selection in bunches
of n(=<max_workers>) workers.
Example:
N = 10 (available workers), n = 4:
1st (session): 1-4, 2nd: 5-8,
3rd: 9,10,1,2, 4th: 3-6, …
“random” random choice (a worker is not
assigned twice)
xpd.resource static [<cfg_file>] [ucfg:<user_cfg_opt>] [wmx:<max_workers>] [selopt:<selection_mode>]
xpd.resource static ~/.proof.test.conf wmx:2 selopt:random
xpd.resource static /afs/physik.uni-freiburg.de/opt/root_v5.18_slc4_py2.4_dcache/etc/proof/proof.conf
Master(s) allowed to connect. Directive active only for Worker or
Submaster session requests. Multiple ‘allow’ directives can
be specified. By default all connections are allowed.
xpd.allow localhost
Server role (master, submaster, worker) [default: any]
Allows to control the cluster structure.
The following (commented) example will set lxb6041 as master, and all
the others lxb* as workers
xpd.role worker if lxb*.cern.ch
xpd.role master if lxb6041.cern.ch
URL and namespace for the local storage if different from defaults.
By the default it is assumed that the pool space on the cluster is
accessed via a redirector running at the top master under the common
namespace /proofpool.
xpd.poolurl lxb0105.cern.ch
xpd.namespace /store
Specifies tracing options. Valid keywords are:
req trace protocol requests [on]*
login trace details about login requests [on]*
act trace internal actions [off]
rsp trace server replies [off]
fork trace proofserv forks [on]*
dbg trace details about actions [off]
hdbg trace more details about actions [off]
err trace errors [on]
inflt trace details about inflate factors [off]
all trace everything
Defaults are shown in brackets; ‘*’ shows the default when the ‘-d’
option is passed on the command line. Each option may be
optionally prefixed by a minus sign to turn off the setting.
Order matters: ‘all’ in last position enables everything; in first
position is corrected by subsequent settings
xpd.trace fork -err rsp
Super-users directive: specify a comma-serarated list of users with
special privileges; the effective user under which the daemon is run
(-R option on the command line) is always privileged.
xpd.superusers usr1,usr2
User access control directive: specifies a comma-separated list
of users allowed to connect to the cluster.
xpd.allowedusers usr1,usr2,usr3
Group information file
Defines the file containing the information about the composition
of the group and their properties. See example in xpd.groups.sample .
xpd.groupfile $ROOTSYS/etc/proof/xpd.groups
xproofd specific security directives, allowing for independent
rules from the ones applying to data serving.
NB: 'if ’ not supported for these directives (protbind can
used for similar purposes).
In the example, GSI authentication is required with no control on CRL.
If this section is missing xproofd falls back to the security setup
defined for data serving.
xpd.seclib libXrdSec.so
xpd.sec.protocol gsi -crl:0 -gmapopt:1 -dlgpxy:1
xpd.sec.protocol pwd -a:1 -d:3 -upwd:1 -keepcreds
This directive may be used to set additional environment variables
for ‘proofserv’. This is useful, for instance, to set client-side
security options. It is possible to set some context depending
keyworks which will be expanded before launching ‘proofserv’; the
syntax is ; keywords currently recognized are:
--> expanded to workdir (see above)
--> expanded to the user’s username
Example:
xpd.putenv MYENV=//.creds
with ‘xpd.workdir /tmp/proof’ will set MYENV to “/tmp/proof/minni/.creds”
for user ‘minni’ and to “/tmp/proof/pippo/.creds” for user ‘pippo’.
There can be as ‘putenv’ directives as needed.
xpd.putenv XrdSecPWDSRVPUK=//.creds/pwdsrvpuk
This directive may be used to set additional rootrc-like variables
for ‘proofserv’. This allows to control everything from this configuration
file. At start-up, ‘proofserv’ will read the additional directives
from the file “session.rootrc” created in the session working dir
by XProofd; “session.rootrc” is actually a symlink to the real file
whose name is in the form
<node_type>--<session_unique_tag>.rootrc
Example:
xpd.putrc AName.AVar: AValue[/code]
the file is the same on both computers, just the paths are slightly different.
