linux - Initializing a Mininet topology from a bash script -

-

i'd automate process of setting mininet virtual machine, sshing vm, starting mininet within vm, , initializing topology. need session remain open can issue commands mininet using created network. works, including initializing network, once bash script ends, mininet tears down topology , exits virtual machine. relevant parts of code follows: 

vboxmanage startvm "mininet-vm_1" --type=headless  ssh -t -y -l mininet -p 2222 localhost << herpderp      # start network     sudo mn --controller=remote,ip=$ip --custom /home/mininet/sf_mininet_vm/mininet/topo_basic.py --topo clos_tree --switch ovsk --link tc  herpderp

things i've tried:

  1. ending here document s0 bash;
  2. ending s0 $shell;
  3. removing delimiter @ end of here document (shot in dark).

(1) , (2) exited mininet , left me prompt in vm, reason can't issue commands it. (3) nothing.

if have python topo in file can run topo using 

sudo -e python <nameofthefile>

for example, if have topo in file pkt_topo_with_loop.py, use sudo -e python pkt_topo_with_loop.py start mininet. have line in bash script automation.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
