Hi What are your system wide limits. ie : cat /proc/sys/net/core/rmem_max cat /proc/sys/net/core/rmem_default Try to : echo 4000000 >/proc/sys/net/core/rmem_default echo 4000000 >/proc/sys/net/core/rmem_max then restart ntop, see if it helps. _______________________________________________ Ntop-dev mailing list [EMAIL PROTECTED] http://listgateway.unipi.it/mailman/listinfo/ntop-dev
