Extreme slow file transferring to ESXi host

[BOSS_Advisors]

Hello, room.

I have a Dell PE 1850 running ESXi 3.5 build 158869 with 2 built-in Intel Gigabit NICs. They are not teamed. I have had extreme slow slow... file transferring the host using scp, wget. SSH is enabled on this server.

I hope everyone can show me how to resolve this issue, perhaps some bebugging methods.

Background: I used to run the VMWare server 1.x on a Linux box. There were no problem with transfering files to the host. I have a habit of putting iso, vmware disk files on the host for building new virtual instances. Nothing has changed. This new ESXi host connects the same network switch, same patch cable. I also have other ESXi and VMWare server hosts in the same rack connecting the same LAN switch. They have had no problem. I attempted a quick fix by plugging the network cable into different port. It made no difference in the file transferring performance. I also try to isolate the issue by enable just one NIC at the time. That made no difference either.

I am stumped. The next desperate thing I might do is upgrading this ESXi box to update 4 | 153875

Please advise.

This is an expected behavior due to how SCP is implemented in ESXi with the limited Busybox console, the detail explanation can be found here: http://communities.vmware.com/message/1159959#1159959

You'll have better luck using the Datastore browser to upload/download files to your local system or vifs.pl with the RCLI if you're using a licensed version of ESXi and not the free version (only pertains to ESXi 3.5u4, u20-u3 works)

Thanks, William, for your suggestions.

But I haven't had this issue on other ESXi hosts using the same file tranfering methods (scp, wget (pulling files)). I routinely do these operations (file transferring).

I just love scp from host to host.

Thanks.

Might want to double check your switchport and your host(s) do not have any duplex miss-match, it's a common problem and easy to validate on both the switch and on the server.

Oh, yea. I took care of that too.

The NICs are gigabit NICs. The LAN is 100MB. At first, I used autonegotiate. Then I set the NIC to 100MB, Full Duplex. It's now 100MBfull-duplex. This didn't work either.

If you're running scp on a non ESXi box, try setting the cipher to blowfish.
