Unable to communicate with www.pfsense.com -> when accessing available packages

[atheos]

Any time I attempt to search available packages, I get this error
"Unable to communicate with www.pfsense.com. Please verify DNS and interface configuration, and that pfSense has functional Internet connectivity."

DNS is pointed to 8.8.8.8 8.8.4.4, no DNS forwarding, and I can resolve hostnames from the command line.

if I try accessing packages manually from the command line
fetch -o - http://www.pfsense.org/packages/pkg_config.8.xml

I get this error.

fetch: http://www.pfsense.org/packages/pkg_config.8.xml: No buffer space available

This is directly connected to the internet, no proxy no other filter/firewall.
I had previously installed a package, so it worked at one time.
Please advise - Thanks

Do you have free space on disk? I've never seen buffer error on fetch cmd.

[atheos]

I'm good on space.  I might lab up another one with the same config, and see if I have similar problems.  This machine is remote and very busy, so I'm hoping I don't have to do that.  Storage is on a 1G CF

@atheos:

you have to mount it rw before any package install, did you did that?

/etc/rc.conf_mount_rw

and

/etc/rc.conf_mount_ro

[atheos]

still no love

Can you fetch to /tmp ?

Steve

[atheos]

cannot fetch to /tmp, but I can create a file in there.

[stephenw10]

Ah so perhaps a network buffer problem, though I would expect some other network issues.
What does 'netstat -m' show?

anything interesting in there?  possibly related, download speeds are great, upload speeds are the opposite of great.

I would say that for some reason your tcp transmit buffer is full. Or at least it's emptying far slower than it should.
Just a guess though.

If you Google the problem you'll see it can be caused by something as simple as a loose network card or bad cable.
