So, I’m getting an error where the network service and NetworkManager apparently don’t agree on how to bring up vlans on bonded nics. Things come up if you ‘ifup ..’ manually. I thought I’d check if there were any updates, forgetting to fix what NetworkManger had done to /etc/resolv.conf and:

http://CentOS.arvixe.com/7.0.1406/os/x86_64/repodata/repomd.xml:
[Errno 12] Timeout on http://CentOS.arvixe.com/7.0.1406/os/x86_64/repodata/repomd.xml: (28,
‘Resolving timed out after 30381 milliseconds’)
Trying other mirror.
^C^C^C
^C^C^C

Current download cancelled, interrupt (ctrl-c) again within two seconds to exit.

Yeah – I did hit it about 6 times there. What do you have to do to make it actually stop in some reasonable amount of time?

  • try CTRL-Z to put that running process in your shell to sleep, then:

    bg 1

    to put the process in the background. Then you can run:

    killall -TERM yum

    to kill all the yum processes. If that doesn’t kill it after running a couple of times, then use:

    killall -9 yum

    and that should do it.

  • Oh, and if you don’t have killall installed, you can use:

    ps -ef | grep yum

    to get the pid and then use:

    kill -TERM pid

    or easier even is:

    kill -TERM `pid of yum`

  • You’re missing a % there

    Or just “control-Z” and then ‘kill -9 %1’

    You don’t need to background the job and then kill every process matching a name.

  • I probably would have just ssh’d in from a different window, except that SSH logins take forever with DNS broken. Thanks – and I think I
    found the source of the network issue. I had a typo in the NM_CONTROLLED=no line in the ifcfg-bond0 file and NetworkManger was failing with:
    Error: no device found for connection ‘System bond0’ when it shouldn’t even have been involved.
