Now it seems that I'll be able to do anything with sudo, without having to su (That's the point of sudo, isn't it? Not requiring the root password..). So how much does the concept of group membership and ACLs apply here? For example, will I be able to run a game if I'm not in the games group? Or will I be able to use the sound device if I'm not in the audio group? Will I be able to manipulate a file or directory via sudo, even if the ACLs (minimal and/or extended) don't allow me to? As you can see, I'm confused as to how sudo would apply to the entire system, rather than just one or two commands that I would specify in the sudoers file. I asked Sanket for his /etc/sudoers file once, when he was on Ubuntu 5.04 I think. It was empty. So am I to understand that this sudo thing is hardcoded into the Ubuntu system? Mrugesh

Hi arun, I have added my contents in reply to the previous posters but Gmail seems to have formatted it in such a way that my text looks like the text of previous poster(I checked that out at the ilug website archives). I am really sorry about it.

[OT] MTNL TriBand - rollover of unused MBs
by Arun K. Khan 07 Dec '05

07 Dec '05

For the past couple of days I have been checking the "Account Summary" for my NU plan and noticed that my unused MBs from Nov/05 have been rolled over to the Dec/05 quota thus giving me much more than 1023MB. At first I thought it was probably an error but apparently it is not. Each time I check - the counter "Free DSL MB ..." is consistent with what it showed at the beginning of the month decremented by my non NU usage. I was under the impression, the download quota got reset to the plan max. every month. Are others with the NU plan getting the same deal from MTNL? -- Arun Khan Linux is like a wigwam - no gates, no windows, apache inside

FAT partition unusable in debian
by mehul 07 Dec '05

07 Dec '05

Hi friends, I had formatted my complete hard drive to install debian linux. One of the partitions I had made was a FAT32 partition. But, due to some mistakes in partitioning I had to repartition my hard disk. But, this time I left my FAT32 partition untouched. I have mounted it as /entertainement Now, I cannot write to that partition using normal user account. Though I can do it as root. I tried to change the permissions using root but I couldn't allowing to do so. Any ideas about what can I do?

Patents
by JTD 07 Dec '05

Visited the Indian patent website http://patentoffice.nic.in Browsing thru the applications reveals filings for such things as methods for zooming, play list, graphic equalisers - all in software - filed by the likes of Samsung (who seems to be one major spin master) , TCS (for a software for some business process) and others jerks from Australia, USA etc. All the applications were filed in 2002. The patent office publishes applications every week. http://patentoffice.nic.in/ipr/patent/journal_archieve/ patent_journal_2005.htm We should scrutinise them and alert FSF India where ever software / computers / electronics and prior art is involved. I plan to do this diligently. Ignore this and u are walking into quicksand. rgds jtd
