Hi,

because i have never heard, and also wikipdia gave me not a complete answer, how secure are installations with cpan like:

cpan -i Email::Outlook::Message

this will install a msgconverter (source: http://www.matijs.net/software/msgconv/

is such an installation comparable with a installation from opensuse repo (in the meaning of virus/trojan/unwanted software)

Installing any software outside the packaging system is never supported and may/will likely clobber a package distributed with the OS or from a software repo like devel:languages:perl. this particular package is in the build service, https://build.opensuse.org/package/show/devel:languages:perl:CPAN-E/perl-Ema..., however it's not in the main d:l:perl repo and if you like it included you should "copypac it from here and then submit it to devel:languages:perl".

...

and is there a posibility to uninstall with cpan and check what files are all generated/changed?

and or did anybody know another tool (from suse repo) which will open *.msg files?

thanks,

simoN

This is not correct. It is correct that opensuse does not support software installed from third parties, but software installed by cpan is supported by the CPAN authors & maintainers. See below about integrity. It is not correct that installing from CPAN might clobber your system. The design of perl prevents third-party installations from clobbering that used by the host system. It is installed in a different place. It is also possible to install multiple versions of perl and/or modules on a system quite happily and manage them.

...

this particular package is in the build service, https://build.opensuse.org/package/show/devel:languages:perl:CPAN-E/perl-Ema..., however it's not in the main d:l:perl repo and if you like it included you should "copypac it from here and then submit it to devel:languages:perl".

Personally I always install perl modules from CPAN because everything is available from CPAN and I don't have to worry about obsolete versions or missing modules etc. I don't have to worry about differences between opensuse and redhat, for example.

...

...
and is there a posibility to uninstall with cpan and check what files are all generated/changed?

Yes, you can uninstall modules from CPAN. I would recommend using cpanm rather than cpan to perform installs, see https://metacpan.org/pod/release/MIYAGAWA/App-cpanminus-1.7044/bin/cpanm which also details many other options to check integrity, examine code before installation etc etc.

Sorry, never used outlook.

Hmm, can you hear my spurs jangling? I typically use it as root, for convenience, but that's very bad for security risk (no risk of clobbering the system though). Perhaps I like living dangerously :) If I need more than one version of perl, then I'll typically use perlbrew as a normal user. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
