The public LoginResult field is marked as deprecated but is still actively used by the package itself (specifically the public Login method writes to this field)...

https://github.com/domainr/epp/blob/main/conn.go#L45-L46

What is the upgrade path for an application using the value assigned to LoginResult?

We successfully connected EPP server but fail when sending manual command (domain registration). We tried several variants using the underlying TLS connection and even modifying the library. We are stuck with the same error every time

Example code:

func euStart() {
	dialer := &net.Dialer{
		LocalAddr: &net.TCPAddr{
			IP:   net.ParseIP("xx.xx.xx.xxx"), 
			Port: 0}}

	eppConn, err := tls.DialWithDialer(dialer, "tcp", "xxx:700", nil)
	if err != nil {
		fmt.Println("EPP dial error: ", err)
		os.Exit(3)
	}

	eppClient, err := epp.NewConn(eppConn)
	if err != nil {
		fmt.Println("EPP init error: ", err)
		os.Exit(3)
	}

	err = eppClient.Login("xxx", "xxx", "")
	if err != nil {
		fmt.Println("EPP login error: ", err)
		os.Exit(3)
	}

	domain := "test6890.eu"
	xml := "<?xml version=\"1.0\" encoding=\"UTF-8\"?><epp xmlns=\"urn:ietf:params:xml:ns:epp-1.0\"><command><create><domain:create xmlns:domain=\"urn:ietf:params:xml:ns:domain-1.0\"><domain:name>" + domain + "</domain:name><domain:registrant>xxx</domain:registrant><domain:contact type=\"billing\">xxx</domain:contact><domain:contact type=\"tech\">xxx</domain:contact><domain:authInfo><domain:pw> </domain:pw></domain:authInfo></domain:create></create></command></epp>"
	eppClient.Conn.Write([]byte(xml + "\n"))
}

We get a runtime error at time of writing to connection (last line):

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x50 pc=0x61b62b]

goroutine 1 [running]:
main.euReg(0x7ffc6eaef84d, 0xb)
        /home/debian/xxx.go:186 +0xdb
main.xxx(0x7ffc6eaef84d, 0xb)
        /home/debian/xxx.go:57 +0x3ae
main.main()
        /home/debian/xxx.go:31 +0xd2

Any ideas? Thanks

From @wbond:

I think the remaining thing to do here is to default uppercase TLD, and use the switch for the dotTLD form ones. Otherwise we'll have to hardcode every Verisign TLD into the code

Alternatively we make it more extensible and pass the subProduct ID in via the extension data parameter and use separate code to determine which should be prefixed with dot. That way domainr/epp is able to handle other registries that may use the namestore extension.

When I run cmd/epp.go to connect remote epp server ,show me the error
Loading CA certificate from cacert.pem
Loading certificate cert.pem and key key.pem
Connecting to epp.registrysystem.net:700

},

Thanks a lot!

To query Verisign EPP servers, you need to use the namestoreExt (https://www.verisign.com/assets/namestore-extension.pdf?inc=www.verisigninc.com) and provide a subProduct from the following:

• .com: dotCOM
• .bz: dotBZ
• .cc: dotCC
• .tv: dotTV
• .com: dotCOM
• .net: dotNET
• .edu: dotEDU
• .jobs: dotJOBS
