AutoFS - Automount

sexta-feira, 19 de abril de 2013

The first step is export the FS to be used on NFS server.
If you don't know how to do that, check the link bellow.

Configuring NFS server

Before to configure autoFS in your client is better check if you can see the nfs FS in your client.
# showmount -e <nfs server>
The return will be the list of what is exported on nfs server and who is allowed to mount/access.

If everything is right until this point... configure the autoFS:
Include on /etc/auto_master what you want mount, we are using the FS /user/home in our example.
# vi /etc/auto_master
/users/home     /etc/auto_home  -nosuid,intr,soft,rsize=32768,wsize=32768

Include on /etc/auto_home the address of your FS (NFS server and mount point):
*       <nfs server>:/home/&

Restart automount
/sbin/init.d/nfs.client stop
/sbin/init.d/nfs.client start
automount



Enable the auto start of AutoFS editing /etc/rc.config.d/nfsconf:
NFS_CLIENT=1
AUTOMOUNT=1
AUTOFS=1

Done

LDAP-UX - How to setup LDAP-UX to authenticate on OpenLDAP

First of all, LDAP-UX does not support updating an OpenLDAP directory, so to get this to work, add the following profile to the LDAP directory (requires the DUAConfig.schema and possibly ldap-printer.schema):

dn: cn=uxprofile,ou=Profiles,dc=example,dc=com
cn: uxprofile
objectClass: DUAConfigProfile
defaultSearchBase: dc=example,dc=com
defaultSearchScope: one
profileTTL: 3600
serviceSearchDescriptor: passwd:OU=People,DC=example,DC=com
serviceSearchDescriptor: group:OU=Group,DC=example,DC=com
authenticationMethod: tls:simple
defaultServerList: <space separated list of LDAP server hosts:ports>

If you don't have the LDAP-UX package installed...

# swinstall -s /yourDepot

Create a key-store:

/opt/ldapux/contrib/bin/certutil -N -d /etc/opt/ldapux

Import the CA cert:
/opt/ldapux/contrib/bin/certutil -A -n ca-cert -t "C,," -d /etc/opt/ldapux -a -i cacert.crt

Configure LDAP-UX:
/opt/ldapux/config/setup
...specify TLS and use port 389.

NOTE: do NOT attempt to extend any sachems -- OpenLDAP does not support this.

To find out if you are working under 32 or 64-bits (PA-RISC)

terça-feira, 12 de março de 2013

You can use the getconf command to get that on PA-RISC:

getconf KERNEL_BITS

You don't need to check that on Itanium, since Itanium is only 64bits.

Rebuild lvmtab

It's quite easy.

Let's begin with a backup:

# cp -p /etc/lvmtab /etc/lvmtab.orig
Remove the old one:

# rm /etc/lvmtab

Now you are ready to rebuild using the vgscan:

# vgscan -v

Check "Real memory" on pa-risc and Ia64

quarta-feira, 23 de janeiro de 2013

I'm listing just one way to check the memory on server but as usual there are many ways to do that.

PA-RISC

# getconf REAL_MEMORY HPUX

ITANIUM

# machinfo | grep -i memory

or

# dmesg | grep mem

Tusc - Process trace "Debug mode"

domingo, 13 de janeiro de 2013

- Why this process is running and is taking so much time???!??!

I am sure someday this question will pass for your mind, in order to try find out what is going on we have the possibility to install a software called "tusc" on HP-UX, a similar command in AIX is the truss (it's native on OS). The output can be not so friendly...

Follow an example using tusc to trace the system calls and signal.

# /usr/local/bin/tusc -apf <pid>

How to mount a windows share on HP-UX

sexta-feira, 4 de janeiro de 2013

After some time away... here is a new post :-)
and by the way... Happy New Year!!

Requirements:

- User account on Windows box
- Root access on HP-UX box
- cifs patch installed on HP-UX
- Network communication between them (client and server)
- Directory shared on Windows

Check if cifs is running:
# cifsclient status

If it is not running..
# cifsclient start

Create a directory to be used for your mount point and use the bellow command to mount:
# cifsmount //WINDOWSserverHostname/DirectoryShared /YourMountpoint -U username

Check the man pages for more flags to be used with cifsmount command.
