I cannot configure and start the drbl server.

[iamd...@gmail.com]

Dear Everyone,

My machines cannot connect to the Internet.
So I download the rpms manually, and install it.
However when I configure the server with command "drblpush -i", there
are many errors.
Here is some of the error message:

1. [root] You should run this program /opt/drbl/sbin/ocs-related-srv
in DRBL server, NOT in DRBL client or other machine.
Program terminated!
2. Can't open /tftpboot/nbi_img/pxelinux.cfg/default: No such file or
directory.
3. Turn on the boot prompt for PXE client...Can't open /tftpboot/
nbi_img/pxelinux.cfg/default: No such file or directory.

About the error 1, I am sure that I am runing it in the server not
client.
And about the others, I don't know howto deal with them.

by the way, my server machine's OS is RHEL4.
And I modify the /etc/redhat-release to redhat desktop 9.

The following is the whole log:

[root@tivm59 setup]# ./drblpush -i

Now we can collect the MAC address of clients!
If you want to let the DHCP service in DRBL server offer same IP
address to client every time when client boot, and you never did this
procedure, you should do it now!
If you already have those MAC addresses of clients, you can put them
into different group files (These files number is the same number of
networks cards for DRBL service). In this case, you can skip this
step.
This step helps you to record the MAC addresses of clients, then
divide them into different groups. It will save your time and reduce
the typos.
The MAC addresses will be recorded turn by turn according to the boot
of clients,
and they will be put into different files according to the network
card in server, file name will be like macadr-eth1.txt, macadr-
eth2.txt... You can find them in directory /etc/drbl.
Please boot the clients by order, make sure they boot from etherboot
or PXE!
Do you want to collect them ?

In the system, there are 3 modes for diskless linux services:
[0] Full DRBL mode, every client has its own NFS based /etc and /var.
[1] DRBL SSI (Single system image) mode, every client uses tmpfs
based /etc and /var. In this mode, the loading and necessary disk
space of server will be lighter. NOTE! (a) The client machine memory
is recommended at least 256 MB. (b) The setting and config files of
client will not be saved to the DRBL server! They are just used once
and will vanish after the machine shutdowns! Besides, if you modify
any file in the template client (located in /tftpboot/nodes), you have
to run /opt/drbl/sbin/gen_ssi_files to create the template tarball in /
tftpboot/node_root/drbl_ssi/. (c) If you want to provide some file to
overwrite the setting in the template tarball when client boots,
check /tftpboot/node_root/drbl_ssi/clients/00_README for more
details.
[2] I do NOT want to provide diskless Linux service to client.
Which mode do you prefer ?
[0]
Full DRBL mode is chosen!
******************************************************
******************************************************
------------------------------------------------------
In the system, there are 3 modes available for clonezilla:
[0] Full Clonezilla mode, every client has its own NFS based /etc and /
var.
[1] Clonezilla box mode, every client uses tmpfs based /etc and /var.
In this mode, the loading and necessary disk space of server will be
lighter than that in Full Clonezilla mode. Note! In Clonezilla box
mode, the setting and config files of client will not be saved to the
DRBL server! They just use once and will vanish after the machine
shutdowns!
[2] I do NOT want clonezilla.

[0]
Full clonezilla mode is set!

When using clonezilla, which directory in this server you want to

Directory for clonezilla saved images: /home/partimag
------------------------------------------------------
If there is a local harddrive with swap partition or writable file
system in your client machine,
do you want to use that swap partition or create a swap file in the
writable filesystem so that client has more memory to use ? (This step
will NOT destroy any data in that harddisk)
[Y/n]
******************************************************
OK! We will try to create a swap space for your client if it has a
local hard drive!
------------------------------------------------------
What's the maximun size (Megabytes) for the swap space ?
We will try to allocate the swap space for you, if it's not enough,
60% of the free space will be used.
[128]

******************************************************
------------------------------------------------------
Which mode do you want the clients to use after they boot ?
"1": Graphic mode (X window system) (default),
"2": Text mode.
[1]
The clients will enter graphic mode after booting.
******************************************************
------------------------------------------------------
Which mode do you want when client boots in graphic mode ?
0: normal login, 1: auto login, 2: timed login
[0]
The clients will wait for user to login when they boot.

Note! If you use graphical PXELinux menu, however client fails to
boot, you can switch to text mode by running "/opt/drbl/sbin/switch-
pxe-bg-mode -m text".
[Y/n]
Use text PXE Linux menu for client.
------------------------------------------------------
------------------------------------------------------
By using alias interface, every client can have 2 IPs,
one of them is private IP for clients connected to DRBL server, and
the other is public IP for clients directly connected to WAN from
switch!
Do you want to setup public IP for clients ?
[y/N]
------------------------------------------------------
Do you want to let DRBL clients have an option to run terminal mode ?
i.e. you want to let that client run remote display (which will mostly
use resources of server), say "Y" here.
Note!
0. If you say yes to this option, this will be a very limited
environment for client, i.e. NO local access for USB, CD, audio,
printer, etc. in client.
1. If your server is not powerful, say "no" here.
2. By saying "yes" here, we will turn on xdmcp,
It is never a safe thing to turn on that. Setting up /etc/hosts.allow
and /etc/hosts.deny to only allow local access is another alternative
but not the safest.Firewalling port 177 is the safest if you wish to
have xdmcp on.
Read the manual for more notes on the security of XDMCP.
Please set it by yourself!
3. If you say "yes" here, you might have to restart your desktop
environment manager (gdm/kdm) later, remember to save your data before
you close applications!
Do you want to let client has an option to run terminal mode ?

exist ?

If you like, you can reboot the DRBL server now to make sure
everything is ready...(This is not necessary, just an option.).
*****************************************************.
DRBL server is ready! Now set the client machines to boot from PXE or

NOTE! If Etherboot is used in client machine, version 5.4.0 or newer
is required!
PS. The config file is saved as /etc/drbl/drblpush.conf. Therefore if
you want to run drblpush with the same config again, you may run it
as: /opt/drbl/sbin/drblpush -c /etc/drbl/drblpush.conf

1. Did you run as root ?
2. Did you run "/opt/drbl/sbin/drblsrv -i" first ?

Hi, Steven Shiau
I am sure that I run the program in root.
And because in the server room, my machine cannot connect to internet.
So I cannot execute "/opt/drbl/sbin/drblsrv -i", so I download the
required rpm packages, and install them by "rpm -ivh *.rpm".
I got the required rpm packages by running "/opt/drbl/sbin/drblsrv-
offline -r". And I am sure that I have installed all the required
packages in the drbl server.

By the way, do you mean that I must run "/opt/drbl/sbin/drblsrv -i",
and I should not install the packages manually?
And is it mean that the program "drblsrv -i" does not only install
required packages, it also do some configuration?

Thank you very much!

My machines info:
1. RHEL4 without any updates
2. I have modified the "/etc/redhat-release", and the drbl program
think that my OS is redhat 9.

[Steven Shiau]

You can use either "/opt/drbl/sbin/drblsrv -i" or
"/opt/drbl/sbin/drblsrv-offline ..." as shown in
http://drbl.sourceforge.net/one4all/
When you run drblsrvl-offline and drblpush, copy and paste all the
messages and post that so that it's easier for others to do something
for you.

Steven.
