Re: Multi-user and shared directories
"umod 002" -> "umask 002" "you can only have one group to a file/directory" : it isn't very right, at least ext2, ext3 and xfs filesystems supports POSIX Access Control Lists (ACL - see "man acl", "man getfacl","man setfacl") and is possible set different access rights (read, write, search/execute) on directories/files for different users and different groups. And on directories is possible set default ACL, again for different users and/or different groups, and new objects inherits default ACL of the containing directory as its access ACL.

Re: Multi-user and shared directories
chgrp dosemu directory_where_are_files_created chmod g+rwxs directory_where_are_files_created SGID bit set on directory will cause trick: all files created under will have group as directory, not primary user group (in this case roberto and fatima).

Fw: Re: Multi-user and shared directories (second try with part 3)
Looks like it's something in the last two paragraphs that causes the mailing list server to reject my this message. I will reword it a bit to see if that solves the problem. Begin forwarded message: You can create your frontend directly with the batchfile using choice.exe, or you can write it using any dos compiler or interpreter, or whatever floats your boat. I personally wrote my frontends using the powerbasic compiler because it's easy to make them bulletproof, plus they are prettier than they would be when using choice.exe. Once you have your user's directory structure, batch files, programs and what-have-you laid out, copy the whole thing into /etc/skel and all new users will automatically inherit everything ready-to-roll as you create them. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com - To unsubscribe from this list: send the line "unsubscribe linux-msdos" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

Once again the over-eager spam filter on the mailing list server has apparently eaten my reply to Roberto. He got it himself as I sent him a copy directly, but it has not appeared on the mailing list here for the benefit of anyone else who might be interested in this topic. I will try resending it to the list now in three parts and see if it gets through this way.

Re: Multi-user and shared directories (reply part 2 of 3)
Just make a symbolic link in ~/.dosemu/drive_c to point to a common directory. For example: mkdir /opt/dosstuff ln -s /opt/dosstuff ~/.dosemu/drive_c/dosstuff Set your permissions in /opt/dosstuff to whatever you want. Now you can use "cd dosstuff" from a dos prompt within your dosemu window to move to /opt/dosstuff. This gives you the flexibility of having one or many shared dos directories, plus having private dos directories for each user. If you choose to do it the way that I do it, your users will never see a dos prompt. autoexec.bat cranks up a frontend menu that exits with various errorlevels to jump to points in the batch file that change directories (private under ~/dosemu/freedos and shared under /opt) and run programs as needed. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com - To unsubscribe from this list: send the line "unsubscribe linux-msdos" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

That's why I love Linux :-) Thank you very much for your help. I was a bit confused at the beginning but now I'm really getting the idea. And all the other guys also gave some pretty cool tips, thanks too. I thought that this list was almost dead, maybe because the documentation is outdated, but seems like there is quite a loyal DOSEmu following here. - To unsubscribe from this list: send the line "unsubscribe linux-msdos" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
Re: Multi-user and shared directories
I use dosemu & Linux terminal server (k12ltsp) by several customers in production environment (mainly some economical DOS programs). There maybe better solve dosemu setting as "hardware oriented", because terminals physical location may determine e.g. local printers use in DOS. Therefore I have on some point in linux fs (/var/DOS/stations in example below) directories describing individual terminals, which act as dosemu boot path instead these in "~/.dosemu/", i.e. they contains drive_c, drives, run directories an other files. And dosemu starting script determine terminal (or server, why not work on it?) from environment setting (use variables LTSP_HOSTNAME, DISPLAY, output of `uname -n`), and then start DOSEMU in manner: xdosemu --Fimagedir /var/DOS/stations/varta \ -f /var/DOS/stations/varta/.dosemurc C:\\runmyapp.bat where "varta" is resolved terminal location (but it maybe e.g. terminal IP address too) By concept of this "HW oriented" instead of "user oriented" dosemu use may be one user login on multiple terminals and run dosemu (I know this is bad idea, but in real world more frequent then multiple users working on single terminal ;)) Sorry for my un-standard english language extension :) Frantisek Hanzlik Roberto Bechtlufft wrote: Hi everybody, I'm new to dosemu and to this list.

Your article is very interesting, but I'm still a bit confused at a few points: "I have a symbolic link in everyone's ~/dosemu/freedos directory that points to a directory under /opt.

Re: Multi-user and shared directories
I'm sorry, I should give you guys more details... the server runs the GNOME desktop from Fedora. DOSEMU is only one of the apps the terminals use, they access a fully-functional GNOME desktop and then call xdosemu through a link on the Desktop. Each terminal access the server as a different user, so I end up with different .dosemu folders, one for each home directory, containing their own drive_c. I'm trying to decide the best way to make all users access the same drive_c.
