I am tring to install Oracle8i onto a Redhat6.2 2.2.14-5.0 box. It

Subject: passive ftp through a router
Date: Mon, 04 Sep 2000 19:34:21 -0500
OK, here's one that's stumped me.
I'm using troll-ftpd, a simple ftp daemon that allows basic ftp
functions.
--> 1.2.3.4/ router/NAT/192.168.129.1 <-> 192.168.129.2/ftp server
I have just set up a router that acts as a limited firewall. It forwards
all ftp requests over to the ftp server. The problem is that passive ftp
connections show up as 192.168.129.2:port, the internal address of the ftp
server.
And no, the router is too stupid to correctly NAT/port forward the PASV stuff.
How can I get the ftp server to a) generate packets wth the address of the
firewall, and b) not reject the returning packets?
I've tried modifying the code, but the ftp server rightly rejects the
packets as spoofed. I don't mind chaning ftp servers if I have to.

I just did the following:
[garry]$ locate netscape | grep xpm
/usr/X11R6/lib/X11/icewm/icons/netscape_16x16.xpm
/usr/X11R6/lib/X11/icewm/icons/netscape_32x32.xpm
/usr/share/icons/large/netscape.xpm

/usr/share/icons/netscape.xpm
/usr/share/afterstep/desktop/icons/16bpp/netscape.xpm
/usr/share/afterstep/desktop/icons/8bpp/netscape.xpm
So, you've got 9 to choose from in Mandrake 7.1. If you run the above command,
you'll see how many are on your system.
As Prasanth has indicated, if you find any, copy them to /usr/share/icons.
To paraphrase another colm denizen, locate is your friend, and grep is its

If it's not actually a resolution problem but strictly a panel/icon issue,
then go into your panel properties. Under KDE's menu go to 'Panel', 'Configure',
'Style' gives you options. Gnome's Panel has a similar configure feature.
As for the desktop icons, the size there can be changed under your
Desktop's config program. KDE has a control center. You can also merely
right-click on a blank part of the panel & you'll get a context menu.

I THINK it is something like the following. /sbin/lilo determines
from the system it is running on what the absolute
address of the kernel it will boot is. So for example, even if
you have a separate boot partition which is mounted on /boot in
the root partition, you don't have to tell lilo about that. It
can figure out where to look just by knowing what the
root partition is. Moreover, all the system needs for
booting is the address of the beginning of the kernel. That tells
the system where the rest of the kernel is to allow further booting.

I am running SuSE 6.4 and have a mount to my Windows 98 partition. I
can write to this partition as 'root', but would like to allow a
particular user to do so. How can I do this w/o buying vmware, etc.? I
have tried various mount options as well as 'chmod' and 'chgrp' options.

Hi,
I'm a linux newbie whose learned a lot in the last month and a half. But
my problem is a real puzzler.
My ftp server as well as my cvs server choke on sending any file bigger
than 2k or so. Smaller files get serrved as expected.
Fetch on my mac shows itself trying to serve the file in ever smaller increments..
from 1024 k a second to 512 to 255 on down to 1 k asecond.
What might be causing this behaviour?
A direct cc is very appreciated

What you are asking is very vague, there are many issues wrt SMP. I'm not a
guru on this, but some of the points that have been raised are.
linux 2.2 is ok at the kernel level to 4 processors. linux 2.4 ok to 8
processors. This means nothing if your application doesn't use it effectively.
WRT java, big issue, thread creation API is easy, many people think the one
thread by client concept is ok, but it doesn't scale. You didn't state whether
thats 400 running threads, either way under whatever OS, you will be hitting
cache hard, and VM tricks (ie context switching) does have a penalty.
I/O versus computation work. 8 processors doing image rendering sounds nice.
linux does try to keep tasks on the same CPU, more cache hits that way, but if
you ask 2 processors to schedule 300 jobs and each processor has 64k cache
then whats the average share of the cache. Memory speed is slow to a CPU.

I don't know how this would have happened, but it looks like
your X11R6 config file, XF86Config, has got munged. You
might find it ('locate XF86Config') and look at its date
stamp. You should be able to recreate a sensible version
by rerunning the X config tool (depends on your distribution
and X version, but it may be xf86config).

I know the gcc options to include header files and libraries during
