Hi everyone,

Since I have a pretty good understanding of Linux, I decided that I wanted to try out NetBSD. I got a completely fresh install of NetBSD 4.0 installed on one of my systems, but now that I've begun configuring it, I've also tried to install additional software from the pkgsrc system which seems like it should work quite well.

Anyways, my problem is that the pkg_add command seems to default to using IPv6 as the main protocol and I get a message saying that there is no route to the host every time I try it. I do not know whether this is a incompatibility with my router, or with my ISP, or something entirely different. However, I have searched google and many other people seem to have had this problem, usually with older versions of NetBSD (3.1?) There never seem to be any answers to these people's questions though. So I am hoping one of you can tell me how to completely disable IPv6 on NetBSD or fix the problem in some other manner.

Thanks for any help you guys might be able to give.

If the domain has a AAAA record, it will default to IPv6 connectivity, as soon as it determines you have no IPv6 connectivity it'll fall back to the IPv4 address... it shouldn't freeze up, try another mirror.

I am using the NetBSD documentation on pkgsrc found here: http://netbsd.org/do...binary-packages

This is what I am inputting for the mirror path as well as trying to install perl.

The first three lines is me setting the mirror and then attempting to install the perl package, the rest is the output. If anyone could help me make sense of the output I would greatly appreciate it. Also, this is way more output than I was getting before. Before it was just the one line that contained the IPv6 address, and the No route to host message.

Have you configured your interface properly?

Please post the output of, "ifconfig -a" and "route show".

Do you use DHCP? PPPoE? or have you configured a static address? is it a direct connection? or do you have a NAT router?

This information will help figure out the problem... my current thoughts are you forgot to setup a default IPv4 route, but... it's only a guess.

[Pharoh]

I connect to my network through my router's DHCP server.
In my /etc/rc.conf I have the defaultroute set to 192.168.1.1, to my knowledge this is all the configuration that I needed to do but perhaps I am mistaken.

Can anyone help me out with this? I would really like to learn about this, and the documentation provided does not thoroughly explain the pkgsrc configuration process and does not explain this error. Any searching that I've done has only produced others asking the same question, but there are never any answers.

[schneis]

I've run into the exact same problem. Had switched to Linux about a decade ago and am trying to fire up a BSD system for the first since that switch. The lack of documentation or preinstalled utils is VERY fustrating.

[Pharoh]

I never did figure that problem out. From what I could figure out, it was either my home router or my ISP that did not support IPv6 which caused the program to hang. The documentation on how to disable IPv6 totally in NetBSD also did not work on my machine.

I have since decided to try out a different flavor of BSD when I get a chance. I am leaning towards OpenBSD but am keeping an open mind. Mostly I just want to learn about the differences between BSD and teach myself the skills necessary to run it on a production system rather than simply toy around with it.

Couple of things that crossed my mind:

- do a "ftp -4 [url="ftp://ftp.netbsd.org/pub/""]ftp://ftp.netbsd.org/pub/"[/url] so that it fetches the IPv4 address and then try with pkg_add;
- try other nameservers on resolv.conf (I have had probs in the past with home routers that didn't handle IPv6 requests that well) or even run your own local caching dns server for bonus points (I think NetBSD includes bind by default).

[Pharoh]

Running my own dns server is not an option for me, however, I will try your other suggestions later. Thanks

I ran into this same problem, and found a rather silly solution. PKG_ADD can't handle the trailing slash properly. Just remove it, and everything should run smoothly.

This doesn't work:
[codebox]export PKG_PATH="ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD-4.0/i386/All/"[/codebox]

This works:
[codebox]export PKG_PATH="ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD-4.0/i386/All"[/codebox]
