Installing texlive under Fedora 17.
by Rolf Turner 12 Apr '13

12 Apr '13

Under Fedora 17 I recently had problems with running latex on a file that previously (under Ubuntu) I had no difficulty with. (A while back I had to switch from Ubuntu to Fedora for reasons that I won't go into here.) I thought that perhaps I might be able to get rid of the flakiness by re-installing texlive. I downloaded the install-tl-unx.tar.gz tarball from http://www.tug.org/texlive/acquire.html unpacked, changed directories appropriately and executed ./install.tl as per instructions. I got an error message: > Can't locate Digest/MD5.pm in @INC (@INC contains: ./tlpkg > /usr/local/lib64/perl5 /usr/local/share/perl5 > /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl > /usr/lib64/perl5 /usr/share/perl5 .) at tlpkg/TeXLive/TLUtils.pm line > 199. > BEGIN failed--compilation aborted at tlpkg/TeXLive/TLUtils.pm line 199. > Compilation failed in require at ./install-tl line 53. > BEGIN failed--compilation aborted at ./install-tl line 53. I looked at line 53 and it is opaque to me. I presume that I need to update *something* w.r.t. perl, but it is not at all clear to me what I need to do. Doing "yum search perl" gave a plethora of hits. I have no idea which are the relevant ones. Then "yum search perl5" basically turned up perl-pgsql_perl5.x86_64. What has pgsql got to do with the price of eggs in China? Can anyone suggest what I need to do to remedy the problem? I have no idea what extra information is relevant, so I have not tried to provide any. If some Good Samaritan would like more information about my set-up, please feel free to ask and I will do my best to supply it. I am fairly computer/Linux/LaTeX literate, but there are gaping lacunae in my knowledge, so please be patient with me. cheers, Rolf Turner P. S. I originally posted this query to texhax, but was told that this is a Fedora issue not a texlive issue, and that I should post to this list. R. T.

Command grep -
by Bob Goodwin 12 Apr '13

12 Apr '13

If I do "less syslog.txt | grep DST=17." I get a mixture of outputs containing "17." I would like to do "less syslog.txt | grep 17.0.0.0 - 17.255.255.255" or "less syslog.txt | grep DST=17.0.0.0/8" but I can't find the correct incantation. The man page doesn't seem to tell me how, at least not in a way that I can understand ... Can someone tell me how?

ZDNet Recommends Linux
by Temlakos 12 Apr '13

12 Apr '13

Everyone: This might seem a little beyond scope to most of you, but: Windows XP is approaching its own EOL. Steven J. Vaughn-Nichols released this article: http://www.zdnet.com/five-operating-system-alternatives-to-windows-8-and-xp… at ZDNet: Five OS alternatives to Windows 8 and Windows XP. And they are, in his view: 5. Using AndroidOS or iOS in a tablet. (In his view: /not/ for the "information producer." Looking things up is one thing. But creating the things for others to look up is quite another.) 4. Mac 3. Linux 2. Google ChromeOS, which he describes as the Chrome browser running on a bare-bones Linux desktop and accessing Google's SaaS offerings. 1. Windows 7. Interesting: he doesn't recommend going all the way to Windows 8. And at the bottom, he adds this: (Quote) You should keep in mind that in the long run, it appears Microsoft really does want to switch you over to a Metro-style interface as part of the "evolution" of Windows 8. If that idea gives you hives, then now is the time to start looking for alternatives. (Unquote) Vaughn-Nichols gives this link: http://www.zdnet.com/no-windows-desktop-mode-no-7000013099/ Temlakos

F18, selinux & sensors

Hi all, I want to monitor hardware temperatures using sensors. sensors is working ok lunched in a terminal but i want to display the output on the web. So i have this simple php: <?php echo exec('/var/www/cgi-bin/my_sensors.sh'); ?> and my_sensors.sh in cgi-bin: #!/usr/bin/bash /usr/bin/sensors exit Why the problem showed in /var/log/messages (and blank web page)? sensors is supposed to run ok, is it? my_sensors lunch sensors = OK sensors try i2c-adapter = deny Do i miss something? setroubleshoot: SELinux is preventing /usr/bin/sensors from read access on the directory i2c-adapter.

I would think it madness to use Fedora in a commercial activity, the upgrade cycle is to frequent and the risks of failure due to the "bleeding edge" to great. What advantage do you think Fedora would give you over whatever you currently use. If you can't convince him to use RHEL/CentOS then I think it wrong to convince him Fedora would be better. Obviously I have know knowledge of your actual business. -----Original Message----- I wouldn't do it on moral grounds: If you want to play/learn/experiment/contribute: use fedora by all means!

Off Topic - Block iCloud -
by Bob Goodwin 11 Apr '13

11 Apr '13

Can anyone tell me how to block Apple iCloud in my router? I've tried filtering icloud.com as mentioned in Google but it still downloads at about 3GB per hour, a rate that would use up my month's allocation in about 8 hours! There seems to be a dearth of information on Google on the subject although it is a recognized problem. Presently I am forced to block all the Apple devices on my LAN. I would like to be more selective and allow them other functions, e-mail and browsing, etc. They can use the 3g/4g system for their iCloud needs. iCloud is really a very inefficient solution to a problem I didn't know existed until my daughter subscribed and put a half dozen devices on it. Any information or suggestions will be appreciated. Bob -- http://www.qrz.com/db/W2BOD box10 Fedora-18 XFCE Linux

XDG_CONFIG_HOME
by Jonathan Ryshpan 11 Apr '13

11 Apr '13

Font control files and a bunch of other stuff for per-user configuration is supposed to be stored relative to $XDG_CONFIG_HOME . I would assume that this is be set by default by either a standard login script, or by the window manager, which in my case is KDE. But it isn't. Is this a problem? If it is a problem, how do I fix it? Thanks - jon

[OT] How to get all packages belonging to a group?
by Joachim Backes 11 Apr '13

11 Apr '13

Hi all, is there a method to list all packages belonging to an installed group? For example, "yum grouplist" lists LibreOffice as installed group, and I want to know which rpm's are belonging to this group (not by using "rpm -qa libreoffice*"). Kind regards Joachim Backes -- Fedora release 19 (Schrödinger’s Cat): Kernel-3.9.0-0.rc6.git0.1.fc19.x86_64 Joachim Backes <joachim.backes(a)rhrk.uni-kl.de> https://www-user.rhrk.uni-kl.de/~backes
