Connection to Citrix without client and in MSDOS

We currently have a Citrix environment setup with users connecting via PNagent and NFuse. We have a rake of Pentium 200 base units that we would like to use to connect to Citrix but would like to speed up the connection by removing the need for using Windows OS and then using ICA client software.

I have built a dos bootable disk which loads a packet driver for the network card and then connects to Citrix server via a demo version of DOSRDPXP. The system works fine. I am now looking to remove the need for DOSRDPXP.

Searching the net for some hints on how I can do this, I can see many sites offering a solution that will perform the above and GET a bootimage from a TFTP server running on the Citrix server. These use Linux, I need to perform the same but using DOS. Can anyone tell me first if this is possible and if so, what do I need please?

The end result of this little project is to get the PCs to boot up via the NIC and perform the above.

Any help will be gratefully appreciated.

Hi nlldavies,
In my experience, it's a waste of time trying to make DOS run better than even Win95 when it comes to Citrix.

I've had the same idea as you, but I've learned that it's not just a question of releasing memory, - windows does handle graphics better than DOS, regardless of how much you fiddle with it.

Please don't compare DOS and Linux, - Linux is extremely more efficient than DOS when it comes to GUI and networking.

With P200's you can easily run Linux. Get a SlackWare, a RedHat 9 a S.u.S.E or similar, and run the ICA from them.

best solution would be MetaFrame, though ;-)

Kind regards,
Sven

Thanks Sven,

Unfortunatley, I need to go this direction as the company does not want any extra expense with licensing these workstations. I think I will drop the NIC boot and just stick with Hard drives as they have DOS licence included.

I'm now looking at WFCLIENT from Citrix but having a bit of trouble getting a decent TCP connection. I've tried the same packet driver as before and can ping the servers no problem, but WFCLIENT fails to connect saying there is no TCP connection. I've also created a network boot disk using NCADMIN in NT 4.0 server which also provides me with a tcp connection tested by mapping to a couple of shares, but WFCLIENT also says no TCP connection available.

Anyone got any clues please?

Nigel,

> the company does not want any extra expense with licensing these workstations

There's no licence fee on a SlackWare Linux !?

Regarding the networking: is TCP/IP compulsory on your network?

 I'd choose a smaller protocol if possible, either NetBEUI or IPX, and these are also much faster in boot-up on a DOS-machine and works fine with the ICA client.

Hi,

boot with PXE over Network (TFTP) a linux OS and start the ICA-Client, thats all...and all for no costs

Thanks to all on this. Sorry it took a while to close (nothing changes between my calls here and work!).

I finally did the PXE linux option last year, got it running quite well but the project was knocked back during presentation as it was relying on Linux :-(

Its now sitting on the back burner ready for re-introduction when the time is right ;-)

Enjoyed the project though.

Cheers
