 +
The ethernet card on the host computer has two ports (eth0 and eth1).
 +
 
 +
eth0 is used to talk to the work and use DNS
 +
 
 +
eth1 is hardwired to a subnet
 +
 
 +
in this case the ROC is configured to address 10.1.1.2
 +
 
 +
The eth1 port is set to
 +
 
 +
"statically set IP addresses"
 +
 
 +
and the manual IP address setting is 10.1.1.1
 +
 
 +
after you activate eht1 you can telnet to the ROC using
 +
 
 +
telnet 10.1.1.2
 +
 
 +
You can then create an entry in /etc/hosts which aliases roc1 to this IP address

I then used the serial port on the host computer to interface with the MVME6100 via the "DEBUG" port.  The debug port took an RJ45 standard cable so I got and RJ45-DB9 converter.  This seemed to work out of the box.  Just in case I ever need to make my own connector record the pinouts below.

 +
 
 +
If you don't use the Kerberos stuff, then remove it ... it's probably
 +
the krb5-workstation package - i.e.
 +
 
 +
rpm -e krb5-workstation
 +
 
 +
I don't know about rexec, but for rlogin and rsh:
 +
 
 +
Edit /etc/pam.d/rsh and change the line:
 +
 
 +
auth      required    pam_rhosts_auth.so
 +
 
 +
to:
 +
 
 +
auth      required    pam_rhosts_auth.so promiscuous
 +
 
 +
and edit /etc/pam.d/rlogin and change the line:
 +
 
 +
auth      sufficient  pam_rhosts_auth.so
 +
 
 +
to:
 +
 
 +
auth      sufficient   pam_rhosts_auth.so promiscuous
 +
 
 +
 
 +
Make sure 'rsh' and 'rlogin' are listed in /etc/securetty

=== text relocation ===
 +
 
 +
SummarySELinux is preventing rcServer from loading /home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so which requires text relocation.
 +
 
 +
;Detailed Description
 +
:[SELinux is in permissive mode, the operation would have been denied but was permitted due to permissive mode.]
 +
 
 +
The rcServer application attempted to load /home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so which requires text relocation. This is a potential security problem. Most libraries do not need this permission. Libraries are sometimes coded incorrectly and request this permission. The SELinux Memory Protection Tests web page explains how to remove this requirement. You can configure SELinux temporarily to allow /home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so to use relocation as a workaround, until the library is fixed. Please file a bug report against this package.
 +
 
 +
;Allowing Access
 +
 
 +
:If you trust /home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so'" You must also change the default file context files on the system in order to preserve them even on a full relabel. "semanage fcontext -a -t textrel_shlib_t '/home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so'"
 +
 
 +
The following command will allow this access:chcon -t textrel_shlib_t '/home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so'Additional Information

==configure rocdaq6==

 +
 
 +
I copied all the software for CODA 3.06 from the host computer daq6 to the ROC
 +
 
 +
scp -r 3.06 rocdaq2:CODA/
 +
 
 +
then i copied the setup file from the host to the ROC.  Since the account on the ROC is a mirror of the account on the host, I did not need to change the setup file.
 +
 
 +
 
 +
When I tried to compile a readout lit on the ROC using the command
 +
 
 +
make -f Makefile-rol I got the error message
 +
 
 +
rol.h: no such file or directory
 +
 
 +
 
 +
I need to setup the ROC to compile readout lists.

DAQ1

Install CentOs

eth1 configuration

The ethernet card on the host computer has two ports (eth0 and eth1).

eth0 is used to talk to the work and use DNS

eth1 is hardwired to a subnet

in this case the ROC is configured to address 10.1.1.2

The eth1 port is set to

"statically set IP addresses"

and the manual IP address setting is 10.1.1.1

after you activate eht1 you can telnet to the ROC using

telnet 10.1.1.2

You can then create an entry in /etc/hosts which aliases roc1 to this IP address

Install tftp onto the Linux host computer

TFTP is used to copy the VxWorks kernel onto the ROC

For CentOS I used yum 

yum install tftp

yum install tftp-server

then I looked in the file 

/etc/xinetd.d/tftp
  1. default: off
  2. description: The tftp server serves files using the trivial file transfer \
  3. protocol. The tftp protocol is often used to boot diskless \
  4. workstations, download configuration files to network-aware printers, \
  5. and to start the installation process for some operating systems.
service tftp

{ 

       socket_type             = dgram
       protocol                = udp
       wait                    = yes
       user                    = root
       server                  = /usr/sbin/in.tftpd
       server_args             = -s /tftpboot
       disable                 = yes
       per_source              = 11
       cps                     = 100 2
       flags                   = IPv4

}

to see how tftp was configured by default. The file tell me that the tftp files should be located in the subdirectory

/tftpboot

make sure your boot kernels are located in /tftpboot 

[root@daq1 /]# ls tftpboot/
boot6100_121_v3.bin  boot6100_122.bin

turn the server on

/sbin/chkconfig tftp on

Set up rsh

turn on rsh

use yum to install the rsh server. 

yum install rsh-server

edit /etc/xinetd.d/rlogin and rsh to allow server 

# default: on
# description: rlogind is the server for the rlogin(1) program.  The server \
#       provides a remote login facility with authentication based on \
#       privileged port numbers from trusted hosts.
service login
{
       socket_type             = stream
       wait                    = no
       user                    = root
       log_on_success          += USERID
       log_on_failure          += USERID
       server                  = /usr/sbin/in.rlogind
       disable                 = no
}

Now reload xinitd 

/etc/init.d/xinetd reload


then add a file called ".rhosts" to the daq account with the IP addresses and usernames


~ >less .rhosts 

 134.50.3.210 daq
 10.1.1.2 roc1

old version is below
~ >less .rhosts
 134.50.3.216 roc1
 134.50.3.216 daq
 134.50.3.210 daq

You Must set the .rhosts permissions exaclty as below otherwise rsh will not work 

chmod 644 .rhosts

Update hosts file

set /etc/hosts file to say 

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain localhost
#::1            localhost6.localdomain6 localhost6
134.50.3.210    daq1.physics.isu.edu    daq1
10.1.1.1        localdaq.physics.isu.edu        localdaq
10.1.1.2        roc1.physics.isu.edu    roc1

the above will assign IP addesses to computer names

test to see if rsh is running

rsh -l daq daq1 ls


if you get the error like 

[root@daq1 xinetd.d]# rsh -l daq daq1 ls
connect to address 134.50.3.210 port 544: Connection refused
Trying krb4 rsh...
connect to address 134.50.3.210 port 544: Connection refused
trying normal rsh (/usr/bin/rsh)

the check if rsh is enabled 

[root@daq1 xinetd.d]# less /etc/xinetd.d/rsh
# default: on
# description: The rshd server is the server for the rcmd(3) routine and, \
#       consequently, for the rsh(1) program.  The server provides \
#       remote execution facilities with authentication based on \
#       privileged port numbers from trusted hosts.
service shell
{
        socket_type             = stream
        wait                    = no
        user                    = root
        log_on_success          += USERID
        log_on_failure          += USERID
        server                  = /usr/sbin/in.rshd
        disable                 = no
}

You need to reload xinetd if you make a change so it looks like above 

[root@daq1 xinetd.d]# /etc/init.d/xinetd reload

Security/Firewall

Turn off iptables

/sbin/service iptables stop

Turn off Kerberos

How can I > configure rsh to use the old, normal way of auth? > > I'm using the latest CentOS4.2

If you don't use the Kerberos stuff, then remove it ... it's probably the krb5-workstation package - i.e.

rpm -e krb5-workstation

I don't know about rexec, but for rlogin and rsh:

Edit /etc/pam.d/rsh and change the line:

auth required pam_rhosts_auth.so

to:

auth required pam_rhosts_auth.so promiscuous

and edit /etc/pam.d/rlogin and change the line:

auth sufficient pam_rhosts_auth.so

to:

auth sufficient pam_rhosts_auth.so promiscuous


Make sure 'rsh' and 'rlogin' are listed in /etc/securetty


text relocation

SummarySELinux is preventing rcServer from loading /home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so which requires text relocation.

Detailed Description
[SELinux is in permissive mode, the operation would have been denied but was permitted due to permissive mode.]

The rcServer application attempted to load /home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so which requires text relocation. This is a potential security problem. Most libraries do not need this permission. Libraries are sometimes coded incorrectly and request this permission. The SELinux Memory Protection Tests web page explains how to remove this requirement. You can configure SELinux temporarily to allow /home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so to use relocation as a workaround, until the library is fixed. Please file a bug report against this package.

Allowing Access
If you trust /home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so'" You must also change the default file context files on the system in order to preserve them even on a full relabel. "semanage fcontext -a -t textrel_shlib_t '/home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so'"

The following command will allow this access:chcon -t textrel_shlib_t '/home/daq/CODA/2.5/CMLOG/2.1/lib/Linux/libcmlog.so'Additional Information

daq6.iac.isu.edu 134.50.218.67 HWaddr 80:c1:6e:21:03:92

The steps used to setup DAQ6 are given below

CentOS 7 installation

DAQ6_CentOS7_install

configure rocdaq6

I copied all the software for CODA 3.06 from the host computer daq6 to the ROC

scp -r 3.06 rocdaq2:CODA/

then i copied the setup file from the host to the ROC. Since the account on the ROC is a mirror of the account on the host, I did not need to change the setup file.


When I tried to compile a readout lit on the ROC using the command

make -f Makefile-rol I got the error message 

rol.h: no such file or directory


I need to setup the ROC to compile readout lists.

Setting up local network

This describes how to plug your ROC's network card into the Host computers network card so the two can talk without using a network switch

1.) You need a crossover network cable to plug your ROC's NIC into one of the host computes NICs( Network Interface Cards)

2.) Then you need to edit files in the subdirectory

/etc/sysconfig/network-scripts

you will need to create a file with the name

ifcfg-eth0

where "eth0" revers to the name used by your OS to define your network card port (you see this name when you use the "ifconfig" tool)

netools can be used to query the network card port


look at the utility "ethtool"
