Total newbie uncertain of problem

JB.Celt · Apr 24, 2016

First off, I'm totally new to FreeBSD and just trying to get my laptop setup.

Problem 1:
I get the following messages after booting in various orders and with some messages duplicating:

date, time, computer name followed by:

Code:

dhclient[583]: send_packet: No buffer space available
dhclient[583]: send_packet: Network is down
Last message repeated 2 times

Problem 2:
I consistently get this result (number of mirrors may vary, but 7 seems the most common):

Code:

root:~# [cmd]portsnap fetch extract[/cmd]

Looking up portsnap.FreeBSD.org mirrors... 7 mirrors found.
Fetching public key from your-org.portsnap.freebsd.org... failed.
Fetching public key from sourcefire.portsnap.freebsd.org... failed.

Fetching public key from ec2-ap-southeast-2.portsnap.freebsd.org... failed.
Fetching public key from ec2-ap-northwest-1.portsnap.freebsd.org... failed.
No mirrors remaining, giving up.

I've tried and gotten the following:

Any assistance would be much appreciated.

Show us the output of /etc/rc.conf and # ifconfig

The root cause seems to be problem1. When the network interface is not configured the services can not work. Please check your /etc/rc.conf.There should be entries as in http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/config-network-setup.html. An example of a /etc/rc.conf network interface setup is

Code:

ifconfig_dc0="inet 192.168.1.3 netmask 255.255.255.0"
ifconfig_dc1="inet 10.0.0.1 netmask 255.255.255.0 media 10baseT/UTP"

which of course must be changed to match your system.

Something wants to use the disconnected ethernet?

more[file] /var/run/smesg.boot[/file]

showed me the following lines:

Code:

iwn0: Intel Centrino Advanced-N 6205 mem 0xf 4900000-0xf4901fff irq 17 at device 0.0 on pci3

em0:<INtel(R) PRO/1000 Network Connection 7.6.1-5> port 0x6040-0-605f mem0xf5200000-0xf521ffff,0xf5236000-0xf523bfff irq 20 at device 25.0 on pci0
em0: Using an MSI interrupt
em0: Ethernet address:28:d2:44:04:68:a9

wlan0: link state changed to UP
wlan0: link state changed to DOWN

Based upon what I see the iwn driver is the one that should be configured for wireless use, but the wlan driver has been setup instead. It's not working and based upon Juha's comment the em driver for the direct Ethernet connection may not be properly configured either.

Does that sound right?

Have a look through the handbook regarding wireless: 30.3. Wireless Networking

Juha Nurmela · Apr 25, 2016

Maybe the "No buffer space available" and OACTIVE is nothing to worry about. You've got an IP address in wlan0, proper looking name servers (?), and all.

Also have a look at /etc/wpa_supplicant.conf, the wpa_supplicant.conf(5) man page, and the wpa_passphrase(8) man page. This line from your ifconfig output:

Code:

ssid xfinitywifi channel 6 (2437 MHz 11g ht/20) bssid 6e:8f:e0:a8:e5:70

...suggests to me that the problem is a missing wifi configuration. "xfinitywifi" is a generic SSID broadcast by Comcast modems.

JB.Celt · Apr 26, 2016

I noticed that my earlier report on my ifconfig missed the final line reflected here:

Code:

iwn0:flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST>METRIC 0 MTU 2290
  ether 84:3a:4b:b5:6f:2c
  nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
  media:IEEE 802.11 Wireless Ethernet autoselect mode 11ng
  status:associated

I also noticed that there is no line in this code indicating an Internet address for the NIC, which led me to believe that the problem was that I needed to configure it. Therefore, after reviewing the iwn(4) man page I altered loader.conf(5) with the following lines as dictated by the man page:

Code:

if_iwn_load="YES"
iwn1000fw_load="YES"
iwn2000fw_load="YES"
iwn2030fw_load="YES"
iwn4965fw_load="YES"
iwn5000fw_load="YES"
iwn5150fw_load="YES"
iwn6000fw_load="YES"
iwn6000g2afw_load="YES"
iwn6000g2bfw_load="YES"
iwn6050fw_load="YES"

I also typed the following command:
ifconfig wlan create [B]wlandu[/B] iwn0 ssid [I]my_ssid[/I] up

This gave me a kind of error message with wlandev in it. I realized I'd miss typed and provided the corrected command.

ifconfig wlan create wlandev iwn0 ssid [I]my_ssid[/I] up

I then checked ifconfig and found this:

Code:

wlan0: flags=8c43<UP,BROADCAST,RUNNING,OACTIVE,SIMPLEX,MULTICAST> metric 0 mtu 1
           ether 84:3a:4b:b5:6f:2c
           inet 0.0.0.0 netmask 0xff000000 broadcast 255.255.255.255
           nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
           media: IEEE 802.11 Wireless Ethernet MCS mode 11ng (autoselect)
           status: no carrier

           roam:rssi 7 roam:rate 64 protmode CTS ampdulimit 8k -amsdutx amsdurx
           shortgi wme roaming MANUAL

This doesn't strike me as an improvement.

Any suggestions on how I should remedy what I've done?

JB.Celt · Apr 26, 2016

Also, I've looked at my /etc/wpa_supplicant.conf

I'll be reviewing it more closely later, but this is what I found:

Code:

ctrl_interface=/var/run/wpa_supplicant
eapol_version=2
ap_scan=1
fast_reauth=1

network={
               ssid="[I]my_ssid[/I]"
               psk="[I]my_psk[/I]"
               priority=5
}
network={
               priority=0
               key_mgmt=NONE
}
