Hi Guys and Gals, My Introduction to the group. My names Darren Foster. I'm a relative newbie to the fedora community. Been using Fedora Core 5 now for the last month or so and finding it very interesting so far I've broken a few things and happily fixed them as you do. I'm a <spit> Windows </spit> Tech support guy for my local community. Providing support to small businesses and individuals. I have to say i love the ease in which windows breaks so easily (rubs hands in a Bill Gates kinda way). My aim is to learn enough about Fedora to implement it in a real world scenario for some customers that are interested in using it as a file server and also run their own web servers. I have a book on LAMP that i have successfully used to set up a web server and get it working which was great fun. I have also successfully set up a SAMBA Server on my home network and this all seems to be good. My plee for help..... YUM - serious Um i think I'm in trouble. I cant get Yum to work for love nor money. I've lost my yum.conf file in the /etc/ folder. The other yum files are there including the yum.conf.bak file. I renamed the .bak file as yum.conf but that hasn't solved the issue I'm having. If i try and use Yum i get the following :- Cannot find a valid baseurl for repo: updates Error: Cannot find a valid baseurl for repo: updates MPLAYER - less serious but would be nice to fix. i installed MPLAYER the other day and for love nor money cant get it to run. If i try to run it from the command line i get the following. mplayer: error while loading shared libraries: /usr/lib/libavformat.so.50: connot restore segment prot after reloc: Permission Denied. FLASH PLAYER - much less serious but would be nice. Just won't work. Ive placed the plugin file in the plugin folder and double checked it many a time and it still wont work. OK Peeps Thanks in advance for any advice or pointers you can give. Regards, Darren Foster
