Re: RE : [lwip-users] netif hostname not active

[Emmanuel Baguia Jr.]

Hello,

Sorry, I did not exactly get your point. What I really wanted to have is to create a gethostname() functionality. What I thought is to enable and activate a hostname for the ethernet interface.

I was able to check the things you mentioned below but somehow got puzzled to what you meant. Im sorry, not quite familiar with lwIP functionality yet.

Thanks

The "netif::hostname" field can be used for DHCP negociation to automaticly register your device name in a DNS (associated to DHCP).

 

If you want to be able to ping your lwip device without a such DHCP/DNS on your network, use the "contrib/apps/netbios sample".

 

You could download it from http://nongnu.mirror.ironie.org/releases/lwip/ contrib-1.3.0.zip.

 

The win32 port show how to use it. You just need to set "#define LWIP_NETBIOS_APP 1" in your lwipcfg_msvc.h file.

You need to have some SMB code.

An example was posted already, check through the archives.

Onderwerp: [lwip-users] netif hostname not active

Hello,

Good day.

I have an issue using the hostname to resolve netif.

When i tried to initialize a hostname for the interface, i did it like this in the ethernet interface init function:

#if LWIP_NETIF_HOSTNAME
  /* Initialize interface hostname */
  netif->hostname = "lwip";
#endif /* LWIP_NETIF_HOSTNAME */

From the lwip/opt.h I enabled LWIP_NETIF_HOSTNAME.

After having a call back funcion for the ethernet interface init, i printed out the status and i got the actual hostname "lwip". Then after initializing everything, I tried to ping the network resource using the hostname "lwip", but it was not successful. What do I need to do for the hostname to be activated? Please advise.

Thanks,
Emmanuel
