Seems to me, that Yum is performing quite badly. I often get network disconnects and Yum keeps spinning after going into 0.0b transfer rates forever and requires a forced kill.
Ahhh.... If you are getting network disconnects then any application yum, firefox, etc. which connects to a remote server would certainly suffer. Some apps/protocols may recover better when the network is restored.
So, are you saying that in your case the network connection is dropping frequently and yum isn't recovering as you'd expect?
I am saying specifically with Yum, it somehow loses the connection, and you can see the transfer rate slowly drop to 0.0b, the ETA grows ridiculously large and getting larger... and stays that way "forever", until one kills yum. This disconnect happens quite often that it takes several yum restarts to complete the downloads.
Or....
Anyone see this problem?
I am of course using NetworkManager, and wonder if I should use the old-network connectivity style?
Are you saying you're having frequent network disconnects, but you don't know why, and you are trying to solve that problem?
Yes, and I do not know why - seems the other apps are running fine, AFAIK, unless there is a test that can ram the network hard to see if it is dropping network connections frequently or not.
So, I am willing to test the network on F12 to discover if the problem is mine alone. Could you or someone tell me how check this out? I had no problems on F9/11 - works fine.
OK, I believe I understand your question a bit better.
Since you are able to use firefox, for example, without problem it doesn't appear you have a true network issue. Or, at least, it isn't local to you. If firefox were also giving you grief it would be a different story.
Generally I'm having no issues with yum on updates or installs. I did have to add "exclude=.gov, .sg" to my fastestmirror.conf as I use yum-plugin-fastestmirror and have had issues with slow network to Singapore.
Are you using yum-plugin-fastestmirror
Yes. I tried it with and without. Problems are the same. Seems to me it is a yum problem, but I am speculating. I am running FF. sendmail, DNS, etc.. a LOT of services and I am not seeing any problems. Just with yum installs/updates.
Just for giggles, can you turn off iptables and try again? I have noticed that in the default ruleset, large transfers sometimes get stalled (primarily outgoing traffic, such as an ftp put or scp from local machine to a remote).
I haven't had time to see which rule(s) cause it. I'm usually pushed for time, so every time I get it, I "service iptables stop", do my transfer, then "service iptables start" and promptly forget to debug it. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer ricks@nerd.com - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - Change is inevitable, except from a vending machine. - ----------------------------------------------------------------------
