Problems with CDROM

deggial · 03-03-2006, 06:07 AM

Hi!

Code:

/dev/hda3        swap             swap        defaults         0   0
/dev/hda4        /                ext3        defaults         1   1
/dev/hda1        /ntfs-win        ntfs        ro               1   0
/dev/hda5        /ntfs-win2       ntfs        ro               1   0
/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

if I don't have floppy can I remove it from here (or may be unmount, I don't know how it is called correctly, I am new to linux) what are the consequences of having floppy drive here without physical device (slackware intallation did almost all the job, concerning mounting all of my partitions), are there any influence on peformance?

P.S. cdrom problem solved

Hi,

Just some simple advice. Creeate a user account and use it!

Running a root account can bite you. You can always su and cause a lot less damage. So for your own sanity, create the user account. That is unless you like the danger!

Not a very smart thing to do....

Seems more like the OP is stuck in 'Windows Mode'

, all important information i keep under xp

to cwwilson721,

what did you mean?

Running as "superuser" is a MAJOR security risk.

As root, you, and ANY PROGRAM RUNNING IN THAT LOGIN has the power to change any file on your system (Like a virus.)

That is the major security flaw in Windows: You are considered as a admin by default, and all programs running under that login are considered an admin. This is why virus attacks in Windows are so easy,

If you are a regular user in Linux, you can't mess with anything important by default. This is why virus attacks in Linux are more difficult.

So login as a regular user. You will be thankful later.

And importtant info in XP is not safe. Save/use it in linux.

ur answer itself have it.
while using $$xp one user one account (most of the time)-tht is the administrator

I agree it is a risk but the security part is due to the chance of someone getting hooks into that account. That risk is there whether you log into the account or not. The breaking of the system by root is the major concern here not a breach by an attack.

As for the virus attack issue. Being a user account is not why the virus is not relevant to linux. Certainly a user can launch an application which could in time with the right coding(virus,worm or whatever) break a system. It is diffcult but not impossible. It is just not as easy as it is with an open system like Windows 95/98/xp/nt. Heck look at whats has happened to MAC OSX.

I do agree that a user account is the safest for any system and limiting the use of su or sudoer rights to users so as to prevent un-warranted harm to the system. The root should be used by users with experienced management techniques and not everyone fits that mold.

The last statement is fair but if need be there are ways to secure even WindowsXP. Even limited ways can provide some of the security needed. Most windows users don't follow good security methods nor use the proper tools to at least limit harm. Sure most of the problems are social but once the systems are broken then the network(LAN or WAN) is generally vulnerable from that system.

As a linux user you must be aware of the system and the possible problems that might arise from an attack. Be it a script kiddy or a true black hat. We (linux users) are not protected from every attack. We need to keep ahead of any possible breach of our system by keeping updated with the OS and the means to protect it!

So to ' Save/use it in linux' may give a false sense of security.

Just my .02!
