1) How do I view and modify the users on my Slackware system after they're created? Say I want to view the groups user foo belongs to, and add him to wheel group?
2) The mail command: how do I...
-Return to the inbox after looking at a message?
-Delete a specific message based on its subject, instead of the sender?
-Mark a message as read?
-Set up the mail program to check an IMAP box, and upload the messages the local system sends it to an IMAP box?
3) Why do I get a message at startup about an undefined mode being passed, and an offer to see the modes available? How do I avoid this message?
4) Where is the /extras that contains the other programs Pat writes about?
5) Why won't my SCSI CD-ROM mount? I am using the adaptec.s kernel, which corresponds with my SCSI card. Here's my fstab:
/dev/sda2 swap swap defaults 0 0
/dev/sda1 / ext2 defaults 1 1
/dev/cdrom /mnt/cdrom auto noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0
Note that this is NOT the computer in my sig. That's my home computer. This is a project station at work. 8)
answer for question 1) another option is if your using kde goto kmenu, system, and Kuser it has all of the users and there info in a nice GUI but will need a restart of the system for some changes
answer for question 3) goto the console either f6 or using a terminal program and as root run liloconfig it will have the same options as when you first configured lilo on install of slackware then when you get to the portion about framebuffer configuration choose something lower then you first time configuring ie if you chose 1024x768x32k then try 1024x768x256 (this is your screen resolution and color depth) if this doesn't help by lower the color depth try lowering the resolution to 800x600 if all else fails there is the standard option that should work on all machines. as mentioned by slackperson sometimes the cards do not support framebuffer at least not the one in lilo
Thanks all. Here's the answers that worked in my case:
1) The user already existed, and I didn't want to recreate the account, so adduser was a no-go. I didn't install KDE, so kuser obviously was out. Thanks to b0uncer for telling me I can can edit /etc/group. I went to the line containing the wheel group, added the user, and viola. Of course, if I had read the sysadmin guide Pat wrote, I would have known that... :S
2) I still can't find the answers here. I read the manual, and while some of the question are answered, the commands suggested don't work. I'll search more for a good guide to mail, and update with my findings.
3) liloconfig makes sense, burnttrees. However, the problem went away on its own... a Good Thing?
