I want to connect a windows workstation to a rh linux network by a 35 meter network cable but it reads 10 Mbps speed and I can't virualize a physical redhat machine in the network
Is the problem with the windows, the cable length or I need to do some configuration in redhat.

No idea, since you've not really given us any details. You don't say what version of Red Hat, version of Windows, you mention virtualization but don't tell us if either of these machines ARE virtual or not, or tell us what kind of NIC's you're using, or what kind of cable.

If you're using an old network cable, that could be the cause. If you're using old NIC's, they could only work at 10MB/s.

Physical redhat 9.0 and servers with RHEL 4
network cable cat 5e

Without knowing anything about your physical network and specific hardware it is impossible to say what could be wrong. The cable length is not a problem but we have not way of knowing its condition.

What does the windows workstation plug into? A switch?

you will have issues with RH9 in the mix and also with the unsupported rhel4 ( only 4.9 is under the "Extended Life Cycle Support" )
contact redhat about the rhel4.9 issues

as to rh9
it is using the 2.2 kernel and well ( as you know) really should not be used

seeing as it went End of Life in 2004
the 10+ year old hardware might not be able to do better .

is the windows end plugging into a eth or usb
if usb and the windows os and hardware is as old as rh9
it will be usb1
or if eth then it is likely a OLD 10/100 eth card

What does the windows workstation plug into? A switch?[/QUOTE]yes it is connected to cisco 2920 switch

The cable is plugged into an eth
and the windows machine is hp workstation xw 4600

...and....
Sorry, but did you think about/research ANYTHING before posting this? Even read the manual on your switch??? The 2920 is a 10/100MBs switch, the absolute BEST you can ever get is 100MB/s. You still haven't said anything about the NIC's in your machines, but since you're using VERY OLD RH 9, I doubt seriously that it would have ANY idea about a gigabit NIC. You MIGHT (and this is a MAYBE) be able to get 100MB/s with some tweaking of your RH 9 installation, but you won't go past that, even IF you manage to get a gigabit NIC working in that ancient system.

Best advice: update everything. Get current OS'es installed on current hardware, or at least more RECENT hardware. Otherwise, enjoy the speed you can get.

The HP 4600 has Gig ethernet port but your saying it only reports 10mb connection?
The switch only shows 10mb connection?

The Windows machine is the HP...the OP didn't actually say what the Linux system was running on. But the switch is the limiting factor here...the 2920 can ONLY get to 100MB/s, no matter what you plug into it. And this:
...still isn't telling us much, OP. We need to know what brand/model NIC's are in the LINUX systems, but AGAIN...you WILL NOT go faster than 100MB/s, period, at all, given the switch you have. It is HIGHLY doubtful that you would even be able to get a gigabit NIC working on RH9. Even RHEL4 is going to leave some doubt, given its age, the fact you're not paying for support for RHEL4 (since you can't anymore, and haven't been able to for some time), and the choices for gigabit hardware of the age of RHEL4 are going to be limited. You probably couldn't even load a driver for it if you had one, since you can't update any of the RHEL4 system.

I failed to ask what the OP meant by 10mbps speed i.e. connection or throughput and how it compares to the rest of the network. If it was throughput and the OP misinterpreted bytes for bites 10 might actually be ok.

True, even though the workstation has a Gig ethernet adapter throughput is only as fast as the slowest device. We are still missing a few pieces of the puzzle.

The OP has mentioned a number of times that upgrading is impossible for whatever reason.

and the best option for the ancient rh9 and antique rhel4
is "the terminal"
on a closed LAN telnet is fine
or
ssh

but NOT running a remote DESKTOP

now you might be able to use "midnight Commander"
over ftp or ssh

You must be speaking of this thread:

...and the OP never said what the application was, where it came from, or anything, really. OP, you need to read the "Question Guidelines" link in my posting signature. Unless you answer questions, provide details, and participate in the conversation, there's not going to be much we can help you with. Again, as in the other thread, you're using hardware that's 12 years old, and outdated, insecure, unsupported software. Trying to patch things together isn't a good idea...your systems are absolutely GOING TO IRREPARABLY FAIL, and there is nothing you can do to prevent it. Updating things now, while you have that ancient system running, will let you do it calmly and get everything right. The alternative is to be doing it late at night/weekend/vacation/whenever things die, and HOPING things work.

Your choice.
