Hi, I'm new to unix and have absolutely no experience with it. I am trying to change the network setting on the only computer on our network with SCO Unix. We switched ISP's and now have a new set of IP's. I can't for the life of me figure out how to go in and change these settings, please help.... (12 Replies)
I am trying to find out if you can create an ACL for telnet sessions and restrict it to a certain subnet/IP range..
any information or where to look would be greatly appreciated.

Hmmm, tough question for me, so I put it here.
I am trying to use shell script or mysql to do the following thing.
tableA, in which all are single ips.

Hi,
I am trying to write a script which would figure out who has run which command and their IP. As i dont have any clue as to which commands would do this job, i request some gurus to help me on this.
Thanks

Is there a command that can lookup ip address, subnet mask, gateway, and dns all at the same. I know ifconfig can lookup ip address and subnet mask. I know route -n can lookup gateway. Not sure about a dns command. So I hope there is a way to lookup ip address, subnet mask, gateway, and dns all at... (2 Replies)
Hi all,
I have setup ipv6 in AIX machine using autoconf6 command.
I was successfull in doing this. after execution of the command local link address was assigned to one of the interfaces

tbrconfig
TBRCONFIG(8) BSD System Manager's Manual TBRCONFIG(8)NAME
tbrconfig -- configure a token bucket regulator for an output queue
SYNOPSIS
tbrconfig interface [tokenrate [bucketsize]]
tbrconfig -d interface
tbrconfig -a
DESCRIPTION
tbrconfig configures a token bucket regulator for the output network interface queue. A token bucket regulator limits both the average
amount and instantaneous amount of packets that the underlying driver can dequeue from the network interface within the kernel.
Conceptually, tokens accumulate in a bucket at the average tokenrate, up to the bucketsize. The driver can dequeue packets as long as there
are positive amount of tokens, and the length of the dequeued packet is subtracted from the remaining tokens. Tokens can be negative as a
deficit, and packets are not dequeued from the interface queue until the tokens become positive again. The tokenrate limits the average
rate, and the bucketsize limits the maximum burst size.
Limiting the burst size is essential to packet scheduling, since the scheduler schedules packets backlogged at the network interface. Limit-
ing the burst size is also needed for drivers which dequeues more packets than they can send and end up with discarding excess packets.
When the tokenrate is set to higher than the actual transmission rate, the transmission complete interrupt will trigger the next dequeue. On
the other hand, when the tokenrate is set to lower than the actual transmission rate, the transmission complete interrupt would occur before
the tokens become positive. In this case, the next dequeue will be triggered by a timer event. Because the kernel timer has a limited gran-
ularity, a larger bucketsize is required for a higher tokenrate.
The interface parameter is a string of the form ``name unit'', for example, ``en0''.
The tokenrate parameter specifies the average rate in bits per second, and ``K'' or ``M'' can be appended to tokenrate as a short hand of
``Kilo-bps'' or ``Mega-bps'', respectively. When tokenrate is omitted, tbrconfig displays the current parameter values.
The bucketsize parameter specifies the bucket size in bytes, and ``K'' can be appended to bucketsize as a short hand of ``Kilo-bytes''. When
bucketsize is omitted, tbrconfig assumes the regulator is driven by transmission complete interrupts and, using heuristics, assigns a small
bucket size according to the tokenrate. When the keyword ``auto'' is given as bucketsize, tbrconfig assumes the regulator is driven by the
kernel timer, and computes the bucket size from tokenrate and the kernel clock frequency.
If the -d flag is passed before an interface name, tbrconfig will remove the token bucket regulator for the specified interface.
Optionally, the -a flag may be used instead of an interface name. This flag instructs tbrconfig to display information about all interfaces
in the system.
EXAMPLES
To configure a token bucket regulator for the interface en0 with 10Mbps token rate and 8KB bucket size,
# tbrconfig en0 10M 8K
To rate-limit the interface en0 up to 3Mbps,
# tbrconfig en0 3M auto
SEE ALSO altq.conf(5), altqd(8)HISTORY
The tbrconfig command first appeared in WIDE/KAME IPv6 protocol stack kit as part of ALTQ tools.
