Here is a recap on different dhcp servers that I have had issues with verios cable modems, DSL and in home wireless firewall / router / dhcp servers both from local computers stores and have opened bugid/RFE 6554498 DHCP host name problem on over the past year and is still not resolved for the dhcpagent that run when you check dhcp vs static on the install or sys-unconfig it

I doubt that they care whether your system gets a name via DHCP. Assigning a name is a typical practice on a large private network, such as at a corporate site. I've found that it's somewhat less common outside that environment. Some do it, and some do not. In the cases where they do not, it becomes your problem.

They have different scopes. Note the final field -- it's "si" for the first one (meaning "snoop" and "dhcpinfo"), and "dm" for the latter one (meaning "server" and "manager"). It works this way because the server has an internal representation of hostname that's used for linkage to DNS. In any event, it's the first entry you want. It looks like this: Hostname STANDARD, 12, ASCII, 1, 0, si It's DHCP option 12, which is described in RFC 2132 section 3.14. > Does any of the other brands of dhcp server provide a Hostname other > then the comcast cable modem did speraticaly only when the lease was > retired did I get the Hostname, you can check the 10u4beta website for > the cases I had opened up under jalzabrewer I don't know if it's a brand issue, and I'm not too sure that it has anything at all to do with the cable modem itself. It's typically a service provider issue. If your cable modem is also actually a NAT and a DHCP server, then it's a local issue with that box. If your cable modem (like mine) is just a simple bridge, and the DHCP server is located on the provider's network (that's how Comcast does it here), then the modem has nothing to do with it. > Also the Timewarner cable modem also seem to work in provdiing a > Hostname , but again the lease time seem to be a issue on snv back before 52 I'm not sure what the lease time issue might be, so I don't think I can comment on that. If there's a problem with Solaris handling valid lease times, then I'd like to know about it, because it sounds like a bug. > In the case of versizon dsl modem I check into it with them > > I try to call netgear and find out if if any of there newer models work > in providing a hostnae on a reserviced dhcp IP address entry. Assuming that device is actually a DHCP server, that sounds like a possible way to go. By why are you avoiding the obvious solution? Add a name -- any name at all -- to /etc/nodename and assign that to 127.0.0.1 in /etc/hosts. I think most users would be _happy_ to avoid getting some baroque name from their ISP, and I'm a bit confused why you want to go out of your way to do this. -- From, Solaris Networking Here is how I tried to get usefull info, so you try and submit: ifconfig nge0 dhcp release snoop -d nge0 -q -o /tmp/dhcp_netgrear.snoop & ifconfig nge0 dhcp start pkill snoop email the bzip2 /tmp/dhcp_netgrear file. is how the /etc/dhcp/inittab is defined, if any one has any other ideas let us know. Also on some dhcp wireless roter dhcp i.e Netgear super g 624 for example you can reserve at mac address o a given hostname , this works under Windows but not in Solaris ether!
