Cannot find required executable /usr/bin/7za

March 24th, 2010 by elizar

The complete error actually is:

Cannot find required executable /usr/bin/7za
pkgadd: ERROR: class action script din not complete successfully

That was the error message displaced when I tried installing two Sun packages as requested by a user, SUNWeu8os and SUNWeulof.

Packages can be found in tge Solaris 10 disk release 5/08. When i tried installing the package I got the error above.

There are two ways you can get that binary and one of them is by using the installation disk of Solaris 10 5/08.

Another one is by installing patch 137321-01 for sparc and 137322-01 for x86

iPad Spoof

March 20th, 2010 by elizar

Apple had open their system for pre-order of their much awaited iPad. April 3 is the start of shipping of the iPad.

It feels like everyone is very much looking forward for this neat device. Although the device is getting tons of positive buzz, there will always be some flaws on that ‘perfect product’.

Check out this spoof video, an ipad parody of the missing features of the IpAd such as a built-in camera, printing support, voice and others.

Funny.

getfacl and setfacl – Unix Access Control (acl) Tool

March 17th, 2010 by elizar

Today’s topic is all about Access List… For Unix and Unix-like system, the usual command to set the file permission is the ‘chmod’ command. However there are instances that we need more flexibility in giving access and control for files and folders. Get it? Access and Control? In this situation, there is a file utility built in Unix called ‘getfacl‘ and ‘setfacl‘.


getfacl
is a file utility for viewing the access control list information associated with a file or directory.

For a memory aid, you can think of ‘getfacl’ as “Get File ACL“.. ACL being Access Control List.

Access control lists are extended attributes added to most major file systems in the 2.6 kernel to improve ability to control the access of files. They allow permissions to be set for individual groups and users and not just the owning user, owning group, and all other users.

setfacl is a command that allows you to set the Access Control List information for a file or directory.

Access control lists are extended attributes added to most major file systems in the 2.6 kernel to improve ability to control the access of files. They allow permissions to be set for individual groups and users and not just the owning user, owning group, and all other users.

You can read man pages for both getfacl and setfacl for more information.

getfacl and setfacl example….

Here’s an example of using the basic funtion of getfacl and setfacl

# getfacl

#setfacl

setfacl -m default:user::rwx,default:group::r-x,default:other:r-x,default:mask:rwx /u06/OneSource/datapump_dbdump

setfacl -m default:user:rcodapp1:r-x,default:group:r-x,default:other:—,default:mas:rwx /u06/OneSouce/datapump_dbdump

ZFS Cheat Sheet Including Zpool, Quotas and Reservations

March 14th, 2010 by elizar

Sorry for the long title post. I just want to easily distinguish this post from my other ZFS post. The reason? For this week, I’ll be working on a server with ZFS filesystem and looks like the SAs for the servers is not yet familiar with the filesystem. I am the newest member of the UNIX team and there’s this request to grow a filesystem that is directly mounted from a disk slice.. Told the guy that we may need to modify the disk geometry and we may have to repartition the disk.. Then I noticed that there is a 140G disk under ZFS partition. I will convince the user to use that spare disk for his project.

And here are the cheat sheet for ZFS/zpool that is related to this week’s project.
