No ping / traceroute / google earth since Pacman Syu today

Hello,

I did a pacman -Syu this morning as I do most days.  To be honest I can't recall precisely what was updated (kernel headers, glibc not sure what else - sorry).  I am now finding that while I can surf the web / be on IRC / dowload my e-mails - some things are broken.  I am not sure if they are related, but they were all working very recently. I use pan for usenet and it is giving me "no such process" when trying to contact my news server.  whois is giving "Temporary failure in name resolution", ping and traceroute are is giving "unknown host" on everything, and google earth "cannot contact  authentication server".

I have not done anthing to my network settings or router, and other boxes using it can still (eg) ping out.

I am nervous about trying a reboot in case I lose the connectivity I have, because I really need this box functional on the net at the moment.

I am baffled.  Any ideas please?

Added by way of edit : - I had both Firefox and Opera open. I tried closing Opera and on restarting it cannot connect to the net. I suppose that I will lose connectivity with other applications if I close them.

Second edit : So I got my head out of my rear sufficiently to read the pacman.log. Todays upgrades were :

I don't know what could cause this apart from glibc.

I am also wondering whether this is the related to the issue metalforever reported earlier today with his "transient resolver failure"

It makes no difference to run as root btw.

Re: No ping / traceroute / google earth since Pacman Syu today

I found that the problem was a DNS one.  ping etc worked if I fed it IP addresses instead of domain names.  I am using pdnsd, which seemed to be working so far as I could tell.  The daemon was running and "pdnsd-ctl dump" output the contents of what seems to be a valid cache.  I changed /etc/resolv.conf to stop using pdnsd temporarily and my DNS came back.

I still don't have the faintest idea why this problem has arisen.  I am too busy to try taking it any further at the moment.  Maybe I should cross-post this in the networking forum.
