Subject: etc/fstab in Suse 7.1: location changed?
Date: Wed, 04 Apr 2001 12:16:47 GMT
Hi,
after installing SuSE 7.1 I found that the etc/fstab is not longer
used for mounting devices at startup. In SuSE 6.4 I could change the
lines in fstab to add or remove a device. If I do it now in YaSt, I
cannot read my fstab with F7 as I could in 6.4
Also when I change a mount point in YaSt, it tells me that I have to
reboot the machine (reminds me to old Windows times :-) ) and I do not
find the changes in /etc/fstab
Can anybody tell me what SuSE have done to the old fstab location?
Where is the information stored now?

Hi,
I want to set up a Linux SuSE 7.1 machine with apache server and want
to use apache as proxy. It works so far for http access but if I try
to use an ftp-Adress the browser tells me that this is switched off
for security reasons.
Can anybody point me to a tutorial or text where I can see how to use
apache as proxy for ftp connections too? Is this possible with apache
or do I have to use squid?

Boot the box. Give lilo an argument like:
linux S
linux init=/bin/bash
linux init=/sbin/bash
linux init/bin/sh
then get hold of the missing file somehow and put it in the appropriate
place..

[ replying to a reply, as the parent post has gone AWOL ]
You don't need to reinstall: just pass the `mem=xxxM' to the kernel
via the Lilo prompt when you boot (e.g., ``Linux mem=300M''). Once
your system boots, you can adjust your lilo.conf appropriately and
then run lilo.

We can type "make menuconfig" to config kernel configuration before we build

If I want to add a new config item, how to do that?
I tried to add a new config item by modify arch/xxx/config.in,

Does I just need to modify arch/xxx/config.in?
or are there something I miss?
Where can I found information about how to modify configuration?

If you arelooking for a Gnome based MUA that can handle multiple accounts
and has a look and feel of the popular windows readers like Outlook and
Eudora.. try CronosII( I am using ver 0.2.1) which is stable and I haven't
run into any problems with it as of yet. Docs state it works well under

I never have edited fstab from YaST, so I can't help you there. Anyway, I'm
running SuSE 7.1 and I just alteded the partition table using fdisk and
configured the new mountpoints to /etc/fstab with a text editor.
Maybe YaST is broken, I don't know. Try editing /etc/fstab with your
favorite text editor instead.

Nope. Check this out, from /usr/src/linux/include/linux/ext2_fs.h:
struct ext2_inode {
__u16 i_mode; /* File mode */
__u16 i_uid; /* Owner Uid */
__u32 i_size; /* Size in bytes */
Note the file size variable (i_size) is a 32-bit unsigned integer,
interpreted as number of bytes, meaning the file size is limited to
4,294,967,296 bytes -- 4GB. This limit is something that's recorded on
the disk structures, so it's not easily changed without making
substantial changes to the filesystem itself.
The limit on the TOTAL FILESYSTEM size is substantially higher:
struct ext2_super_block {
__u32 s_inodes_count; /* Inodes count */
__u32 s_blocks_count; /* Blocks count */
This gives a maximum of 4,294,967,296 blocks, each of which can be up to
4KB in size (IIRC), hence a 16TB filesystem size limit. Again, this
limit is encoded in the filesystem's on-disk data structures.
My understanding is that ReiserFS has precisely the same limits as
ext2fs for these two critical values. XFS and JFS both use 64-bit file
size and total blocks pointers, although they use them in somewhat
different ways, so exact limits are different. My understanding is that
XFS's limits are 8,192PB (8,388,608TB) file size and 16,384PB partition
size, with JFS at 4PB file size and 32PB partition size. (With those
limits, presumably JFS isn't using the full 64 bits, or has some other
factor limiting file and filesystem sizes.) My figures on XFS and JFS
are based on sketchier data than my ext2fs or even ReiserFS figures. (I
just checked the reiserfs_fs.h header and found a 32-bit file size
value [presumably in bytes, although the comment didn't make this
explicit] and a 32-bit "offset" value [presumably in blocks] for the
start of the file. If the latter is the only ReiserFS partition size
limit, that'd make its maximum partition size just over 16TB.)
Now, all this said, I'm not a filesystem developer, so perhaps my
understanding is in error. For instance, the i_size variable in the
ext2fs code might be purely cosmetic; something else might impose the
real file size limits. Every piece of evidence I've seen, though,
points to this being correct -- a 4GB file size limit in both ext2fs
and ReiserFS, along with a 16TB fileSYSTEM size limit. Because they use
64-bit pointers, JFS and XFS have substantially higher limits.

Actually, the VFS layer in the 2.2.x kernels imposes a 2GB file size
limit. I've heard that's been lifted in the 2.4.x kernels (or with
patches to the 2.2.x kernels), but I've not tried to confirm this. As
you say, there are various libraries, utilities, and even individual
programs that impose their own limits, as well. Before lifting those
limits will do any good, though, the limits inherent to the
filesystems' data structures must be lifted.

I found a couple of posts of his, like the following:
http://groups.google.com/groups?q=alexander+and+viro+and+filesystem+and+%22file+size%22&lr=&safe=off&rnum=1&seld=987407376&ic=1
These posts do not give specific limits; they just state that the
ext2fs file size limit is not 2GB. I never said it was 2GB.
If you've got more substantive evidence that the ext2fs file size limit
is 4TB, as you claim, please post it; I'd be very interested in seeing
it.

You've been cracked by a new worm, because you did not apply the updates

Yes...and a pretty good explanation, IMHO.
Games are, aside from an OS maybe, the most expensive and time-consuming
software to try and develop. Note I'm talking about Quake-type games here,
not the endless minesweeper and solitaire clones.
You need more than just competent programmers for a 3D game. You need one
who's extremely good with 3D math *and* Assembly if you want to have a 3D
engine with a decent framerate. You'll need at least one other programmer,
if for no better reason than to have another set of eyes on the code,
though more likely there's things that your 3D guru just can't do as well.
Then you need someone to come up with music for the game. Coming up with
good video game music isn't easy, especially if you're working with MIDI.
Then you need someone to do the graphics. The hundreds upon hundreds of
graphics. Floor, wall, and ceiling textures. Character skins. UI icons.
Menus. Everything.
And you'll need someone to design the levels. This takes a *lot* of talent
if you want the player to keep playing level after level.
Oh, and someone to design the models for the players and enemies. This,
while still involving 3D modelling, is a different game than level design.
Of course, nothing says these all have to be *different* people...but most
of them will be.
The last thing you need is time. The kind of time that people who have
other jobs, and families, won't have. You need to be able to lock
yourselves away, preferably *together* for hours and hours each day, for
months at a time. Look how long it takes to develop a game like Quake 3.
Then keep in mind that, for one, the people at id Software are game design
gurus, and two, they spent *all* their time developing that game.
And *that's* why you don't see quality, free 3D games very often.
