Is it possible to mark executables, without requiring relinking?

gives me error saying "couldn't display smb://, because nautilus cannot
contact the SMB master browser.Check that an SMB server is running on
the local network."
but i can open up network places by manually typing smb://ipaddress of
hostname and it does work.

RE: Well supported, reliable NICs for Redhat Linux/Fedora
by Eric Ebert
I'm using the NetGear FA311. I have three of them in two boxes both of which are using
Fedora Core 1 with 2.6 kernel. I've been using them since RH 7 and I've never had a
problem with them.

Hi folks,
Can I get some people's recommendations on PCI/PNP network cards
that run very stable under Linux 2.4. I hear the Intel 10/100 eepro based
cards are good but are a little more costly. What about D-Link, Realtek,
Linksys etc for $10-15 cards. I am only looking for 10/100 Mbit cards. Do
not even begin to recommend 3com 905 based cards which is the cause of my
headaches currently with Fedora :-).
Thanks,
Dan

I have a dozen or so machines running Linksys cards. I've purchased most
of them for about $5-$10US, and some were free after promotions and
rebates. In the past 3 years, one has died.
I didn't have as much luck with Realtek 8139 based cards and have seen 4
die in the past two years. Don't remember the manufacturer however.

I try to find the returned/open box cards at my local BigBoxRetailer. I
think I've even seen some NICs at Big Lots.
