Wine & A networking Issue

Well, I have been going through distribution after distribution, just checking them all out... and here are the two issues I have come across with Fedora.

First off, Wine. I downloaded the latest , wine-20040213-1fc1winehq.i386.rpm and also wine-20040121-1fc1winehq.i386.rpm . When I try to install Ventrilo, I recieve the following error..

err:virtual:map_image Standard load address for a Win32 program (0x00400000) not available - security-patched kernel ?
I have been able to install Wine on Redhat and Slackware with no problems but with Fedora I get this error. I have googled it and found out that its a known issue with Fedora. I have followed some tips about modifying the prelink. This is the fix that supposedly help some out,

PRELINK_OPTS="-mR --no-exec-shield"
I still recieve same error, after many reboots and prelink -au and prelink-a.

Any ideas or has anyone found a different fix?

Second question, for some odd reason on Fedora I can't ping my router? I will try best to describe how my setup is setup, let me know if you need more information

Cable Modem
|-> Zonet 8 Port Switch
      |-> My Windows XP / Fedora Box ( ) 
      |-> 4 Port NetGear Router ( / )
      |     |
      |     |->  Red Hat Box ( )
      |     |
      |     |-> Brothers Comp
      |     |
      |     |-> Mail Server
      |     |
      |     |-> WAP
      |-> Step Fathers Computer

Ok I hope that helps. Now heres my scenario... I can log onto XP and load webpages and ping the Red Hat box just fine. Same the other way around, the red hat box can ping the XP one.

Once I log onto Fedora though, its a completly different situation. I can not ping either way. I have a DHCP assigned address, and it remains the same. Anybody have any suggestions?

Actually now that I am thinking about it.. I might have to use the same MAC address that I have in Windows. I will check it out and get back to whomever. Thanks for the help!

With networking -- the easier way is to start without DHCP / any other stuff and just try configuring it manually

So if your router (Netgear) has its IP address (gateway)

set your Linux box as say or whatever your router wants -- it'll be in the manual what IP addresses to use

Then for the DNS names set these up to what you got from your ISP / Cable co.


ADSL / Cable in =======> ADSL MODEM====>ROUTER====>LAN Switch

LAN Switch

====> Router

====>LINUX BOX (say)

====> Windows etc

====> Other computer

This should work -- then mess around with DHCP etc.

Good Luck

Thanks for the reply.

This is done, I manually specified it, and its functional. This situation is very strange because I have no problem connecting to my mail server ( ) from Fedora. On Windows XP I can ping, connect to apache server on the Red Hat box, and so forth. So can everyone else on the internet, just not when I am logged onto Fedora. I did finally notice this though, when I am on XP my IP address is, but when I am on Fedora it is I can browse any website from Fedora, so the IP is valid, but just not my own! It's really weird and I am totally confused why its doing it. I think I will now try to log onto Fedora and specify my IP as Whenever my DHCP lease is up I will jsut have to redo it I guess. Thanks for the help!

In regards to your wine problem, I found this solution on a wine list, and it works for me:


>>>> >>

>>> >

BTW, this command disables the exec-shield functionality for all the processes
running on the system, which may be a bit unwise...
There is a command called setarch, which allows to disable exec-shield on a
per-proces basis. Simply call "setarch i586 wine <arguments>" and it will start
wine with exec-shield disabled, while other processes will still be protected
by it.
I'm not using Redhat/Fedora, but I patched my kernel with exec-shield to improve
system security; I'm running wine from a simple wrapper called swine :-)) (for
"setarch wine") and I have no problem with it...
WIth regards, Pavel Troller
