Hello,

Trying to run jagornet dhcp server on windows 10 as part of a development test environment.

I've tried as a service with the config files defined, had trouble (says it can't find the interface), now just trying to run it from command line with no options, still throws an exception. Below output is from an elevated command prompt, logged in with local admin rights:

Did some additional debug, the server will run with the default config files (xml and xsd), it will also run with our modified xsd. It will NOT run with our custom config (we were under the impression that our config was loading when running the command line dhcpserver start command, so hadn't dug into the custom config file as potential source of trouble).

The configuration is a bit complicated, multiple V4 and V6 scopes, custom options in each:

Doing some banging around and stare & compare, this line was blowing it up (which I believe was part of the example file):

<ns2:dhcpServerConfig xmlns:ns2="http://jagornet.com/dhcp/xml">

We removed that line after looking at the sample files, and without changing anything else it worked (we then found/fixed any of our own syntax problems in the configuration).

However, it appears there is a possible bug in the custom options logic-

We are using your DHCP server to provide info to sensors, ipv4 and ipv6. The sensors support SLAAC, DHCP, and manual programming as well as combinations (where we SLAAC for an address and use DHCP for DNS servers and our own custom option (184) which provides IP addresses of our servers which the sensors speak to).

When we configure v4 and/or v6 options (using subOptions or vxOtherOptions) for anything other than 'string' the DHCP server throws an exception (null pointer) when trying to service a request that asks for that option. No matter which type we use (ipAddress, opaqueDataOption, opaqueDataOptionList). If we set to string, it works without issue, for any of the others it throws what looks like the same exception. We have tried with the examples from the documentation (copy/paste) and see the same behavior.

This is reproducible every time.

Here is an example of the xml file, with the exception below:
(this works)

<name>Remote IPv6 Client Link (Unicast/Multicast traffic)</name>

</v6DnsServersOption>

<domainNameList>sdsdev.com.</domainNameList>

</v6DomainSearchListOption>

</stringOption>

</optionDefList>

</v6OtherOptions>

</v6MsgConfigOptions>

</linkList>

(this doesn't-we tried short & long notation for the IP, also same problem with V4, and with all the different data types-ip, opaque, ip list, opaque list, etc)

<name>Remote IPv6 Client Link (Unicast/Multicast traffic)</name>

</v6DnsServersOption>

<domainNameList>sdsdev.com.</domainNameList>

</v6DomainSearchListOption>

</ipAddressOption>

</optionDefList>

</v6OtherOptions>

</v6MsgConfigOptions>

</linkList>

Hello,

Thanks for your interest in Jagornet DHCP!

The default config/dhcpserver.xml file appears as follows in the distribution bundle:

This config file is provided as-is to allow simple bootstap of the server with minimal configuration. It will generate the v4 and v6 server IDs and rewrite the file. Further configuration can be performed via the REST API. The config/dhcpserver-basic.xml and config/dhcpserver-sample.xml files provide some example configs, and both include the full XML namespace declaration including the schema reference as follows:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE xml>
<dhc:dhcpServerConfig xmlns:dhc="http://jagornet.com/dhcp/xml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://jagornet.com/dhcpserver.xsd">

...

</dhc:dhcpServerConfig>

This is for use by XML validating editors. As you discovered, your initial problem in your config was that both of these XML namespace definitions were included:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:dhcpServerConfig xmlns:ns2="http://jagornet.com/dhcp/xml">
<!DOCTYPE xml>
<dhc:dhcpServerConfig xmlns:dhc="http://jagornet.com/dhcp/xml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://jagornet.com/dhcpserver.xsd">

The NullPointerException that you've discovered is now logged in GitHub here: https://github.com/jagornet/dhcp/issues/73

Thank you for reporting this bug! We will be releasing a patch for this issue soon.

Greg,

Thanks so much for your response, much appreciated. I think I may have found another problem, but just as likely I'm doing something wrong :)

I think you may have a typo here:

wrapper.app.parameter.4=-10.10.0.71

There is an unnecessary dash (-) preceeding the IP address. It is more clearly seen in the log message:

INFO|15884/0|Service jagornet-dhcpserver|22-12-10 23:17:48|IP Address failure: java.net.UnknownHostException: -10.10.0.71

Thanks again for reporting this bug with the complex option defs. Issue #73 has been fixed.
Jagornet DHCP Server 4.0.1 release is available. See the GitHub project - https://github.com/jagornet/dhcp

Greg,

Thanks for catching that. I looked at that file a hundred times before posing the question...can't believe I missed that. Sorry to bother you with it. We did grab the latest build and fix our typo and it works perfectly, thanks so much for the fix for the null pointer.

I'm going to lobby my company for a donation for your product.

Thanks,
Steve

No problem, glad I could help.

Donations would be greatly appreciated!

Thanks,

Greg
