Cercasi simulatore di rete che funzioni sotto [RISOLTO]

[Meskalamdug]

In breve qualcuno sa se esiste un simulatore di rete(router cisco,switch,etc)
stile gns3?
Gns3 non riesco a farlo andare in quanto richiede qemu patchato,e il qemu patchato
è il 0.14.1(di tre anni fa!!) che non compila sotto slackware 14.1.
Qualche consiglio?

[Meskalamdug]

sul sito di gns3 dicono che qemu 1.1 dovrebbe andare anche senza patch
ma non va...appena do console non appare un corno

[ponce]

l'ho appena installato da SBo e sembra funzionare (pero' come dice nel README, ci vuole un immagine del Cisco IOS da installarci sopra).

L'immagine cisco va bene,sono i guest di qemu che non vanno..

[ponce]

che qemu usi?

hai provato con quello su SBo?

Sto provando l'ultimo 1.7.0..
e non va.
Lo slackbuild è quello di SBo

[ponce]

io non ho un immagine IOS (per ora), ma domani posso provare.

[Meskalamdug]

Partendo da una configurazione pulita non funziona nulla

[ponce]

io invece ho provato a emulare il 7200 e funziona: anch'io ho qemu 1.7.0, compilato (non ho idea se e' quello, dovrebbe servire per l'emulazione arm) avendo installato prima device-tree-compiler.

Quella è una console su Cisco,e va pure a me.
Io sto parlando di guest qemu,prova ad avviare un guest e dimmi se va.

[Meskalamdug]

Con il tuo qemu parte.
Però mi da cpu al 100% e le immagini non vanno..
che disastro.

[ponce]

ho fatto una prova con gns3-0.8.6: ho messo, nelle preferenze del qemu guest, come "qemu options", "-display sdl".
ho provato ad avviare l'immagine di linux-core-4.7.7 ed e' partita regolarmente.

[Meskalamdug]

Grazie,ora va.

[ponce]

sai cosa? se usi -current e' possibile che l'opzione di qemu "-display sdl" da oggi non ci voglia piu': sembra che fosse un problema legato alle opzioni di compilazione di cairo (ed e' possibile che venga anche aggiornato sulla 14.1).
