Hello, I have a question regarding ACLs and their availability across different Unix platforms via NFS share.
If I have an AIX/FreeBSD/Solaris/HP-UX client that has an nfs share from a different system mounted on it, will the ACLs on the nfs share be processed properly?
My guess is that as... (2 Replies)
What do you think of the idea of selling flash drives already prepared to boot Puppy Linux on PCs? (I still need to see if I can boot on Macs using online instructions I've found.) I know it's not too hard to prep your own flash drive, even if you have to buy one first, but just think about why... (8 Replies)
Hello. This is my first post to this forum. I've read many of the posts over the last two or three years and I've learned a lot.
I'm creating a live Linux distribution using the Linux Live Scripts -- just as a hobby project -- and I'm wanting to create an automated way for a user to copy the... (7 Replies)

I have two SCO openserver systems, 1 in the US and 1 in the UK.
I am setting up a vpn to connect the two local networks that also have windows pc's on them.
Is there a way that either unix system can see the hard drive on the other unix system so that I can share data between them.

I know that Unix is different from windows in that it needs more manual configuring but how do I get Solaris 8 (Intel version) to recognize my floppy drive and cd-rom??
I mean does it automatically detect the drives at startup and I have to mount them or do I have to create the drives somehow and... (1 Reply)
I have this 36 GB harddisk which houses the root partition along with a 28 GB partion for the rest of the data. The thing I wish to do is that partition this 28 GB into two partions. I have never partitioned the root disk. I just wanted to know whether is it possible to do when the disk is online... (1 Reply)

IOSTAT(8) BSD System Manager's Manual IOSTAT(8)NAME
iostat -- report I/O statistics
iostat [-CdDITx] [-c count] [-M core] [-N system] [-w wait] [drives]
iostat displays kernel I/O statistics on terminal, disk and CPU operations. By default, iostat displays one line of statistics averaged over
the machine's run time. The use of -c presents successive lines averaged over the wait period. The -I option causes iostat to print raw,
Only the last disk option specified (-d, -D, or -x) is used.
The options are as follows:
-c count Repeat the display count times. Unless the -I flag is in effect, the first display is for the time since a reboot and each sub-
sequent report is for the time period since the last display. If no wait interval is specified, the default is 1 second.
-C Show CPU statistics. This is enabled by default unless the -d, -D, -T, or -x flags are used.
-d Show disk statistics. This is the default. Displays kilobytes per transfer, number of transfers, and megabytes transferred.
Use of this flag disables display of CPU and tty statistics.
-D Show alternative disk statistics. Displays kilobytes transferred, number of transfers, and time spent in transfers. Use of this
flag disables the default display.
-I Show the running total values, rather than an average.
-M core Extract values associated with the name list from the specified core instead of the default ``/dev/mem''.
-N system Extract the name list from the specified system instead of the default ``/netbsd''.
-T Show tty statistics. This is enabled by default unless the -C, -d, or -D flags are used.
-w wait Pause wait seconds between each display. If no repeat count is specified, the default is infinity.
-x Show extended disk statistics. Each disk is displayed on a line of its own with all available statistics. This option overrides
all other display options, and all disks are displayed unless specific disks are provided as arguments. Additionally, separate
read and write statistics are displayed.
iostat displays its information in the following format:
tin characters read from terminals
tout characters written to terminals
Disk operations. The header of the field is the disk name and unit number. If more than four disk drives are configured in the sys-
tem, iostat displays only the first four drives. To force iostat to display specific drives, their names may be supplied on the com-
KB/t Kilobytes transferred per disk transfer
t/s transfers per second
MB/s Megabytes transferred per second
The alternative display format, (selected with -D), presents the following values.
KB Kilobytes transferred
xfr Disk transfers
time Seconds spent in disk activity
us % of CPU time in user mode
ni % of CPU time in user mode running niced processes
sy % of CPU time in system mode
id % of CPU time in idle mode
/netbsd Default kernel namelist.
/dev/mem Default memory file.

iostat appeared in Version 6 AT&T UNIX. The -x option was added in NetBSD 1.4.
