Hi,
I have a script that's being called via a crontab which is a wrapper script that creates a log for the script that gets executed. Within the script that gets executed, it also run's subscripts. I've been able to get everything to work .. but the issue is one of the subscript that goes out... (4 Replies)
Hi All,
When starting an SSH tunnel, piped output 'hangs' (on AIX) :
ssh -Nf -Llocalhost:22000:server:22 proxy | cat -vet -
... hangs ...
Does anybody know how to prevent this?
Of course, in my script I don't use the tunnel as I do in the example above. In my script the call to ssh is... (7 Replies)
Hello;
Am trying to generate runaway proc report using ssh thusly:
===================

But the output to e-mail comes out rather garbled ..
Any ideas... (1 Reply)

Hey Guys,
i have a script that generates logs at our isilon storage.
The part of the script is to geneate logs and grep its name:

The code below works ok, however; I need to output the results to a local variable

Hi everyone, after about 2 days of scratching my head on this one, I'm finally ready to punt this and ask for some actual help. Here's the situation. We have 1 server, that runs multiple VM's. To gain access to those VM's we ssh from host01 to the other vm hosts. For example when we first log... (4 Replies)
Hi, I need to get the output of ssh for multiple servers using for loop which is returning how many users are logged in, one below the other. But i'm getting output in single line for one of the servers.

x86_64_set_mtrr
X86_64_GET_MTRR(2) BSD/x86_64 System Calls Manual X86_64_GET_MTRR(2)NAME
x86_64_get_mtrr, x86_64_set_mtrr -- access Memory Type Range Registers
LIBRARY
x86_64 Architecture Library (libx86_64, -lx86_64)
SYNOPSIS
#include <sys/types.h>
#include <machine/sysarch.h>
#include <machine/mtrr.h>
int
x86_64_get_mtrr(struct mtrr *mtrrp, int *n);
int
x86_64_set_mtrr(struct mtrr *mtrrp, int *n);
DESCRIPTION
These functions provide an interface to the MTRR registers found on 686-class processors for controlling processor access to memory ranges.
This is most useful for accessing devices such as video accelerators on pci(4) and agp(4) buses. For example, enabling write-combining
allows bus-write transfers to be combined into a larger transfer before bursting over the bus. This can increase performance of write opera-
tions 2.5 times or more.
mtrrp is a pointer to one or more mtrr structures, as described below. The n argument is a pointer to an integer containing the number of
structures pointed to by mtrrp. For x86_64_set_mtrr() the integer pointed to by n will be updated to reflect the actual number of MTRRs suc-
cessfully set. For x86_64_get_mtrr() no more than n structures will be copied out, and the integer value pointed to by n will be updated to
reflect the actual number of valid structures retrieved. A NULL argument to mtrrp will result in just the number of MTRRs available being
returned in the integer pointed to by n.
The argument mtrrp has the following structure:
struct mtrr {
uint64_t base;
uint64_t len;
uint8_t type;
int flags;
pid_t owner;
};
The location of the mapping is described by its physical base address base and length len. Valid values for type are:
MTRR_TYPE_UC uncached memory
MTRR_TYPE_WC use write-combining
MTRR_TYPE_WT use write-through caching
MTRR_TYPE_WP write-protected memory
MTRR_TYPE_WB use write-back caching
Valid values for flags are:
MTRR_PRIVATE own range, reset the MTRR when the current process exits
MTRR_FIXED use fixed range MTRR
MTRR_VALID entry is valid
The owner member is the PID of the user process which claims the mapping. It is only valid if MTRR_PRIVATE is set in flags. To clear/reset
MTRRs, use a flags field without MTRR_VALID set.
RETURN VALUES
Upon successful completion zero is returned, otherwise -1 is returned on failure, and the global variable errno is set to indicate the error.
The integer value pointed to by n will contain the number of successfully processed mtrr structures in both cases.
ERRORS
[ENOSYS] The currently running kernel or CPU has no MTRR support.
[EINVAL] The currently running kernel has no MTRR support, or one of the mtrr structures pointed to by mtrrp is invalid.
[EBUSY] No unused MTRRs are available.
HISTORY
The x86_64_get_mtrr() and x86_64_set_mtrr() were derived from their i386 counterparts, which appeared in NetBSD 1.6.
