I am still running a whole bunch of other applications here including Mail, Skype, Web Browser and twelve other utilities.

And the memory use is very light

Because I have the

ghostios

and

 sparsemem

enabled the memory footprint is very small.

    Heh, try running bgp on those routers, it will eat up your PC, you, your fridge, or anything that is in 100 meters distance :-)

    and GNS never again, dynagen is perfectly ok and doenst get stuck.

    • http://etherealmind.com Greg Ferro

      I am. It’s an emulation / abstraction of an MPLS core.

  • http://www.rxtx.co.uk rxtx

    I’ve run into memory leaks most times I’ve used GNS lately which is a shame. Hopefully they’ve improved this in the new version

    • http://etherealmind.com Greg Ferro

      In GNS or in Dynamips or in Dynagen. Do you find running the dynamips natively does not have the memory leaks ?

      • http://www.rxtx.co.uk rxtx

        The process with the leak is dynamips-wxp. I haven’t tried it natively yet, will give that a shot next

    Well, my project file did not load after upgrading to 0.7 because it contained a PEMU PIX. I had to create a new project with a PIX, then add a license key, then cut the resulting project config, then insert it back into the original file.

    [pemu localhost]
    section had to be changed to

    [qemu localhost:10525]
