Hi,
I'm looking for some way to bring up in a shell window a realtime (or something that updates at 10 second intervals or whatever) bandwidth monitor.
I just want something that shows me how much kbps is going in and how much is going out of each interface. Is there something that might... (2 Replies)
i have two questions actually...
i need to block certain ports with openbsd and PF in a large lan, the firewall is supposed to be a router between the internet and the first lan switch.
first of all, would this work at all in theory?
second, i tried doing this a few days ago at a huge lan but i... (2 Replies)

NAME
DLASCL - multiplie the M by N real matrix A by the real scalar CTO/CFROM
SYNOPSIS
SUBROUTINE DLASCL( TYPE, KL, KU, CFROM, CTO, M, N, A, LDA, INFO )
CHARACTER TYPE
INTEGER INFO, KL, KU, LDA, M, N
DOUBLE PRECISION CFROM, CTO
DOUBLE PRECISION A( LDA, * )
PURPOSE
DLASCL multiplies the M by N real matrix A by the real scalar CTO/CFROM. This is done without over/underflow as long as the final result
CTO*A(I,J)/CFROM does not over/underflow. TYPE specifies that A may be full, upper triangular, lower triangular, upper Hessenberg, or
banded.
ARGUMENTS
TYPE (input) CHARACTER*1
TYPE indices the storage type of the input matrix. = 'G': A is a full matrix.
= 'L': A is a lower triangular matrix.
= 'U': A is an upper triangular matrix.
= 'H': A is an upper Hessenberg matrix.
= 'B': A is a symmetric band matrix with lower bandwidth KL and upper bandwidth KU and with the only the lower half stored. =
'Q': A is a symmetric band matrix with lower bandwidth KL and upper bandwidth KU and with the only the upper half stored. = 'Z':
A is a band matrix with lower bandwidth KL and upper bandwidth KU.
KL (input) INTEGER
The lower bandwidth of A. Referenced only if TYPE = 'B',
KU (input) INTEGER
The upper bandwidth of A. Referenced only if TYPE = 'B',
CFROM (input) DOUBLE PRECISION
CTO (input) DOUBLE PRECISION The matrix A is multiplied by CTO/CFROM. A(I,J) is computed without over/underflow if the final
result CTO*A(I,J)/CFROM can be represented without over/underflow. CFROM must be nonzero.
M (input) INTEGER
The number of rows of the matrix A. M >= 0.
N (input) INTEGER
The number of columns of the matrix A. N >= 0.
A (input/output) DOUBLE PRECISION array, dimension (LDA,M)
The matrix to be multiplied by CTO/CFROM. See TYPE for the storage type.
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,M).
INFO (output) INTEGER
0 - successful exit <0 - if INFO = -i, the i-th argument had an illegal value.
