  1. OpenSSH is excellent. Installed "sshd" on our Windows-10 box. Works good. Please, more Linux utilities esp. for Network Monitoring & Mgmt

    I just installed OpenSSH on a Windows-10 box we got for the lab. This is great - the documentation was clear, and I just used the Powershell method to quickly install and configure a Linux-style "sshd" server for this Windows-10 machine. We run mostly Linux machines, and were really pleased to see Windows-10 had scp pre-installed. But there was no "sshd" (we could scp and rsync to the box, but not log into to it.) But a quick google-search "how to enable sshd on Windows-10" took me right to the Microsoft documentation page, with a good detailed description of exactly…

  2. Add support for 32-bit ASNs

    Add support for 32-bit ASNs on BGP.

    The Add-BgpRouter cmdlet and the Set-BgpRouter cmdlet seem to limit the LocalASN and PeerASN parameters to 16-bit. The parameters themselves are 32-bit unsigned integers. However in C:\Windows\System32\WindowsPowerShell\v1.0\Modules\RemoteAccess the cmdlets show a validator stopping it from being any larger than 65534.
    I propose changing the validators to allow for 32-bit ASNs. The current setup limits Windows servers to only being able to use 16-bit ASNs and prevents them from peering with any device that uses a 32-bit ASN

  3. Enable-NetLldpAgent not useful

    The Enable-NetLldpAgent , in order to be useful in proper management of a network, should allow setting TLV subtypes.
    Or...........Some options I would prefer:
    set TLV 1 to ID subtype 5 (network address) instead of subtype 4 (MAC address)
    set TLV 2 to ID subtype 5 (interface name) instead of 3 (MAC address)

    include the optional TLV 5 system name

    MAC address is easily obtained by other networking tools. Using this as the information for mandatory TLVs is redundant and useless.

  4. Expose whether DNS Client Server Address assigned by DHCP or Static

    The Get-DNSClientServerAddress cmdlet does not provide information on whether or not the Server Addresses were assigned via DHCP or have been statically assigned.

    This is presumably because the information is not provided to WMI/CIM.

    This information is available by using NETSH, so it is available in the OS.

    This would allow some problems in the xDNSServerAddress resource in the xNetworking DSC resource module (in the Resource Kit) to be solved.

    For more information about the problem and why it is causing problems, please see this issue in the xNetworking resource module: https://github.com/PowerShell/xNetworking/issues/164

  5. Roll back network changes if not confirmed

    If you change network settings, you should be prompted to confirm once the change has finished in the same way as display settings. If not the change is rolled back.

  6. DNS Manager should sort IP addresses numerically

    In DNS Manager the Data column treats everything as a string so it sorts alphabetically. Instead, it should be smarter and recognize different types of data and sort those numerically. Specifically, it should recognize IPv4 addresses and sort them numerically.

    We could go from:

    To:

    10.0.0.1
    10.0.0.2
    10.0.0.100
    10.0.0.101
    10.0.0.200
    10.0.0.201

  7. add a comments field only visible in the DNS Manager console.

    This would help with DNS Management by having the ability to add notes to static A records and aliases

  8. DnsServerResourceRecord does not support multi-string records

    RFC-4408 (section 3.1.3) https://tools.ietf.org/html/rfc4408#section-3.1.3 defines the use of multi-string records for SPF (DNS TXT records), however the Get- or Add- DNSServerResourceRecord commands do not support this. For the Get- the actual DNS record is truncated to 256 chars, and for the Add- it simply errors out with an invalid propery.

    Example of a valid DNS record (that can be configured by the DNS GUI)
    $RecordName = "spfrecord"
    $RecordText = "v=spf1 ip4:192.168.0.1 ip4:192.168.0.2 ip4:192.168.0.3 ip4:192.168.0.4 ip4:192.168.0.5 ip4:192.168.0.6 ip4:192.168.0.7 ip4:192.168.0.8 ip4:192.168.0.9 ip4:192.168.0.10 ip4:192.168.0.11 ip4:192.168.0.12 ip4:192.168.0.13 ip4:192.168.0.14 include:spf.protection.outlook.com mx -all"
    $Zone = "contoso.com"
    $Type = "TXT"
    $DNSServer = "DC1.contoso.com"
    Add-DnsServerResourceRecord -DescriptiveText $RecordText -Name…

  9. Remove-DhcpServerv4Reservation [IP Address] removes all reservations in the scope, even if the IP is not a scope IP

    When using Remove-DhcpServerv4Reservation and just giving it an IP address without using the option -IPAddress, the cmdlet removes all reservations and turns them into leases.

    This should not happen if the IP address is not a scope IP identifier and should throw an error rather than removing all reservations.

  10. Send network configuration scripts on the hyperV hosts before running it

    When doing modifications on virtual network equipment in SCVMM, we often lose connectivity because a switch that allowed connection is deleted before another one is created. The problem is that scripts regarding network configuration are executed remotely, wich means that we’ll lose connectivity at some point and won't be able to complete the script. We believe it would be safer to send the script entirely to the hosts before executing it, so they could complete it without any remote help and reconnect when it has been executed.
