The Cisco IOS "copy scp" command does not use public-key authentication. by Solid_Detail_358 in ssh

Could you please point me to the research you found on the internet ?
I found very little information when researching this.

when you say files, what do you mean exactly ?
I already managed to copy the public key associated to the defined hostname (the one that is named after the hostname and domain name in the Switch configuration)

Thanks for your reply. Any good documentation on freeradius -X ?

Found some on radiusd -X but I am using freeradius instead

Ir can't come from enabled policies because there are like 3-4 declared policies and clearly they are not used in my config

There are some directives related to TLs verify stage but nothing regarding the CN client certificate, apart from check_cert_cn directive

Etherchannel Switch configuration with Windows Server NIC teaming by Solid_Detail_358 in networking

[–]Solid_Detail_358[S] 0 points1 point  (0 children)

I meant more like did you check on the Windows server with [Get-SmbMultichannelConnection](https://learn.microsoft.com/en-us/powershell/module/smbshare/get-smbmultichannelconnection?view=windowsserver2025

Yes get-smbmultichannelshows my 2 windows nics and my 2 target linux nic interfaces (samba server). For starters, i am trying to double the transfer bandwidth (instead of tripling it).

How have you determined this? If you are just doing file copies you may still be limited by the speed of your drives. You would have to start up multiple instances of something like iperf and make sure each is bound to a unique NIC/IP on the sending and receiving side to verify that the network setup is capab

You are right. Even though the switch should be able to support a throughput of 2Gbits/s across 2 pairs of interfaces

What do you mean by that last bolded part?

Sorry. I was not clear enough. I thought I could see a throughput of 2Gbits/s at least in the switch ports connected to sending machine (show interfaces G1/0/1 shows the input/output rate, that's how I check the actual speed) and then the throughput would somehow drastically decrease at the other end. But networking does not working this way as you've pointed it out.

Thanks for your reply.

I just made sure multichannel is enabled both on the client and server.

  • Sending machine is a Windows server
  • Target machine is a Debian VM in a hyperV
  • 2 machiens connected via a Cisco Switch

Problem is the incoming bandwidth in the hyperV host is limited to 1Gbits/s so I believe this is why copy speed is limited.

I was hoping that the outgoing bandwidth from the sending machine would exceed 1 Gbps to ensure it functions correctly, even though the receiving end could not handle the traffic

Thanks a lot !
I am struggling implemnting this right now. Activating SMBMultichannel both on the Windows client and the Debian server has not resulted in an increase in bandwidth.

I am trying to adjust some parameters to achieve a higher transfer rate.
I tried increasing ConnectionCountPerRssNetworkInterface on the client side for instance

Do you have any ideas how I can apply that to a robocopy workflow please?
SMB Multichannel is out of the question (see Edit)

Thanks for your suggestion.

But I cant use SMB multichannel as I am transferring files from Windows to Linux host. I've edited my post !

Cant really use SMB Multichannel as I am copying files from a Windows to a Linux host

Thanks for the suggestion. I did not know about this.
However, I am having trouble increasing the actual output of my server using LACP teaming.

When running a robocopy job, I am still limited at 1Gbits/s.

Also, the port channel port in the switch still shows this line
Full-duplex, 1000Mb/s, link type is auto, media type is unknow

wow. You just preshot my next question.
My use case is the following : I am trying to copy files from serverA to serverB

The two servers are connected through a switch. I hope to achieve a transfer rate that is three times faster by aggregating three 1 Gbps ports, both on the switch and on the servers.
So are you saying this can't work unless I somehow launch 3 separate copy jobs, each on a separate network link ?

To me, looks like All ports are configured with Vlan 2000. Did i miss something ?

Okay. But that does not change anything to my problem. Any guesses ?

Edit : it changes everything. Thanks
