Review: Peazip 5 decompresses everything

Leave a comment

Peazip is one of the most versatile file compression and archiving utilities out there—possibly the most versatile—and it’s free. It’s also quite easy to use and offers the same features found in programs such as WinZip and WinRAR such as context menu integration, passwords, command line usage, etc.

Peazip supports every compressed archive format I’m aware of: 7Zip, ARC, GZ, TAR, ACE, RAR, etc. There’s also support for both ISO and UDF disc images and Linux package formats such as DEB, RPM, PET/PUP, and SLP. As a bonus, you can open Mac HFS DMG files. There are more, but the point is that there’s little out there in the way of compressed file you can’t browse and extract from.

As you can tell from the file type associations dialog, Peazip supports a lot of formats.

While I’ve always appreciated the effort that goes into this piece of free software, I’ve also installed, then uninstalled Peazip several times over the years because of operational and performance issues. This has left me using WinRAR, which while a bit old-school looking, is rock-solid and fast. Version 5 of Peazip seems quite a bit more stable, but it still has a tendency to not close and launch 100% smoothly when you’re dealing with multiple instances. Also, the progress bar is still inaccurate, claiming far less progress than as actually been made. Several times, it was only 25% across when the task completed.

Can't chgrp. Error – chgrp: changing group of `<file>': Invalid argument

Leave a comment

By venmx

I found that I cannot chgrp for some reason with error:

chgrp: changing group of `’: Invalid argument

This happens on all NFS mounted disks on client machines.

We use AD (not my call) for authentication and it also provides groups.

We have a NFS server running Scientific Linux 6.3 which mounts SAN devices on FC connect. These are then exported via NFS. Clients are all CentOS 6.4.

The clients hard mounts the user’s home disk with intr,sync and various tuning options. The other disks use autofs.

AD is configured so that each user has a matching UID and GID, essentially making them the exclusive member of their own group. Not useful for sharing files unless you don’t mind making all your files accessibly by world, o+.

We need groups so that we can add members who are then able to chgrp what ever files they’d like to share with members of the same group. All seems pretty straight forward so far.

I used to run OpenLDAP with Kerberos to do all this, I had LDAP manage autofs and groups. Everything worked perfectly.

But now I cannot chgrp.

The permissions of the exported directories on the NFS server are:
drwx–x–x root root /san/home
drwxrwxrwx root root /san/otherdisks

But under home each user directory is owned by the user:
drwx–x–x user1 user1 /san/home/user1

NOTE: “other” means machines within same organization using same AD but built by other departments, “this” means the machines I built.

In the following scenarios it fails:

1. As AD user on “this” client machine on own home on “this” NFS server.
2. As AD user on “this” client machine on automounted disk on “this” NFS server.
3. As root on “this” client machine on automounted disk on “this” NFS server.

In the following scenarios it works:

1. As AD user on “this” client on local partitions where permissions allow.
2. As AD user logged in directly on “this” NFS server on any partition where permissions allow, including on SAN disks.
3. As root on “this” file server on any partition.
4. As AD user on “other” clients on export from “this” NFS server.
5. As AD user on “other” clients on export from “other” NFS server.
6. As AD user on “this” client on export from “other” NFS server.

This issue shows itself when I extract TAR files whilst on client machines to NFS exported shares as AD user or root, can’t chgrp!

I can do everything else, I can create, delete, even do newgrp and change my default group then create new files belonging to me with GID of new group. But still can’t chgrp

How to avoid TAR of directory with no permissions?

Leave a comment

By rajangupta2387

Hi Users,

i have a situation as below;

Code:
-rw-r--r-- 1 t1elkpe cmptl 0 Mar 18 12:00 file2
---------- 1 t1elkpe cmptl 0 Mar 14 16:07 file1
d--------- 3 t1elkpe cmptl 3 Mar 18 11:23 fd

now when i am tarting the above files below is what i get as output.

HTML Code:
[t1elkpe@ /u01/appl/t1elkpe/pst/max/SCRIPTDIR$]> tar cf test.tar f*
tar: /u01/appl/t1elkpe/pst/max/SCRIPTDIR/fd: Permission denied
tar: file1: Permission denied
[t1elkpe@ /u01/appl/t1elkpe/pst/max/SCRIPTDIR$]> tar tvf test.tar
tar: blocksize = 4
d--------- 1005/250 0 Mar 18 11:23 2013 fd/
-rw-r--r-- 1005/250 0 Mar 18 12:00 2013 file2

As visible fd directory is still tar in the final tar. Is there any way i can avoid this completely.

Any help is appreciated.

Thanks and Regards
Rajan gupta

PeaZip 4.8.1 (KDE Archiving/Backup)

Leave a comment

ThumbnailPeaZip 4.8.1
(KDE Archiving/Backup)
PeaZip is a cross-platform, desktop neutral file archiver utility that provides an unified portable GUI (Qt and GTK2) for many Open Source technologies like 7-Zip, FreeArc, PAQ, UPX…

Create 7Z, ARC, BZ2, GZ, *PAQ, PEA, QUAD/BALZ, TAR, UPX, WIM, XZ, ZIP files

Extract over 150 archive types: ACE, ARJ, CAB, DMG, ISO, LHA, RAR, UDF, ZIPX and many more…

Features of PeaZip includes extract, create and convert multiple archives at once, create self-extracting archives, split/join files, strong encryption with two factor authentication, encrypted password manager, secure deletion, find duplicate files, calculate hashes, export job definition as scripts.

Installation and integration in *x systems:

If experiencing problems running PeaZip compiled for Qt, start it as:
peazip -style=cleanlooks

If experiencing problems with PeaZip compiled for Qt widgetset, it is available PeaZip compiled for GTK2 libraries as alternative, or it is possible to compile the application for its own Qt version using Lazarus/FreePascal IDE, which supports compiling the sources for various widgetsets: Win32, WinCE, fpGUI, Carbon, Qt, GTK1, GTK2.

On Linux systems, PeaZip installer automatically create menu entries for KDE (on most versions); to add PeaZip to Gnome menu copy the “Archiving” folder placed in PeaZip/Freedesktop_integration/nautilus-scripts to system’s Nautilus script’s folder (in most versions open “Scripts” menu in system’s context menu, and select “Open script’s folder”).

Qt widgetset packages requires Qt 4.5 or more recent, and needs libQt4Pas.so installed in /usr/local/lib or equivalent directory (copy the file and run ldconfig; it is done automatically in installable packages), such as /usr/lib or /usr/lib32 on some 64 bit distributions.
A copy of libQt4Pas.so is available in PeaZip’s directory, ./usr/local/share/PeaZip/ for the installable packages.
If the Qt version does not start on some systems, as some system’s visual styles may cause recursive repainting error, you can fix the problem starting it in a console (or script) as: peazip -style=cleanlooks

On 64 bit systems, backend binaries in PeaZip/res path can be freely replaced by users with respective 64 bit counterpart (if available).

PeaZip Portable is standalone software and doesn’t need installation and can be used from removable or remote paths without changing the host system (useful is system needs to stay library-freezed).
‘Freedesktop_integration’ folder in PeaZip’s path contains .desktop files and Nautilus scripts to help users to configure tighter integration of PeaZip with desktop environment’s menus.

changelog:
2013 01 31
Improved GUI, various fixes.

2012 12 06
Added native build of PeaZip Portable for BSD systems

2012 11 23
4.8 New graphic files management features, new alphabetically sorted Functions sidebar, improved mail functions integration
