  • 1. Ultra 2 disk size...can you go above 18 gb?
    I was wondering if anyone is running above an 18GB hard drive on an Ultra 2? I want to purchase a larger drive and want to make sure it will work. Thanks, Justin
  • 2. tar only files, not directories
    I want to tar up an assorted collection of files and subdirectories e.g. tar cf aFirstTarBall.tar SomeFile SomeDirectory etc. The typical tar ball contains the following: Case#1 ------ PROMPT> tar tf aFirstTarBall.tar SomeFile SomeDirectory/ SomeDirectory/AnotherFile etc. What I want is Case#2 ------ PROMPT> tar tf aFirstTarBall.tar SomeFile SomeDirectory/AnotherFile etc. This way, if files change, I can do tar cf AnotherTarBall.tar `tar tf aFirstTarBall.tar` The problem with this command under the tarball of Case#1 is that SomeDirectory/AnotherFile gets put into AnotherTarBall.tar twice -- once because "tar tf" returns "SomeDirectory", and again when it returns "SomeDirectory/AnotherFile". Depending on the nested subdirectories, some files can get put into AnotherTarBall.tar many times. Is there a simple way to get tar to only include files rather than directories? A clumsy way is find SomeFile SomeDirectory etc. -type f | xargs tar cf aFirstTarBall.tar Works as long as the number of files returned by "find" is less than some platform-dependent limit. Because it's wordier, it is prone to error. Another clumsy way is tar cf AnotherTarBall.tar ` tar tf aFirstTarBall.tar | sed '/\/$/d' ` Thanks for pointing out a much more direct way, if one exists.

  • 3. Solaris 8 sendmail 8.11
    Just wonder if anyone can give advices at the following issues on solaris 8's sendmail version 8.11: 1. Is there a way to build sendmail.cf file to only allow localhost connections? 2. when start sendmail daemon with the default sendmail.cf, "netstat -a" show there is a "submission" listening, is this the "MSA"? Does sendmail 8.11 really need the "submission" to be at "listen" status? Will this cause some protential security risk? Is there a way to secure this? 3. When turn on "Smart host relay", will it cause some security problem? Thanks !
  • 4. How to read network stats?
    Hi, I'm new to using Solaris. I want to read in the amount of bytes sent/received from one of my external interfaces. On linux I used to do this by reading in the /proc/net/dev entries but I have no idea how to do the same on Solaris. netstat -in doesn't tell me the amount of bytes sent/received and only gives me a packet count. Can someone please tell me how to do this? Thanks, Steve
  • 5. The perfectly mirrored system ...
    I 've got a SunFire v440 with 4 internal and 8 external disks. All the critical file systems and database slices are mirrored, via Solaris Volume Manager, in a RAID 1+0 arrangement. A copy of the metadatabase is on every disk. My question is: if a single disk fails ..... how will I know? (I've a supplementary whist I'm being lazy: where is the Solaris equivalent of HP-UX's rc.log - the log written to at boot time and in fact whenever a run-level change is effected - located?) thanks Neil

Netra X1, Corrupt text received via serial connection

Postby James » Sat, 20 Aug 2005 00:42:26 GMT

Hi,

I have just got hold of a Sun Netra X1 and would like to install
Solaris 9 (or 10) onto it.

The problem I have is that when I connect to the serial console I get
the LOM prompt alright, but after typing some commands like "help" I
get back scrambled text with some parts recognizable. I am using a
Cisco serial cable which has the same pinout as the sun original cable
(I have also made up a cable as per the Sun spec in the netra manual).

I have also tried connecting to the server via a Linux server, a Sun
Sparstation 5 and a windows laptop (using a variety of software
hyperterm, kermit, etc). All have the same issue.

I'd be very grateful for any opinions, ideas, etc.

Thanks in advance.

James.

If some of it is (nearly) readable, I would suspect you have parity
set wrong on whatever terminal or emulator you're using to connect.

If none of it is readable, I would suspect the baud rate is wrong.

I'm using 9600 baud, no partity, 1 stop and 8 bit word (9600 8N1). All
as per Sun manual. it does seem to start out ok, but gets worse ... not
sure if that sounds like a buffer issue of some kind....

Check the LOM settings.  They might have been changed from the default
of 9600 8N1.

I'm not sure about the UARTs in those systems but you might be overflowing 
the buffer on the sending or receiving end.  Try turning on hardware 
(RTS/CTS) flow control (although, given the speed of today's computers, it 
seems a bit strange that the receiving end cannot handle 960 cps without 
flow control, but it's possible).  It might also be the cable.  Is it 
shielded?  Is it a ribbon cable?

Thanks Rich, I checked but the LOM settings are correct (9600 8N1)
..... :(


Re: Netra X1, Corrupt text received via serial connection

Hi Yves, I'll try changing the flow control. I'm using a Cisco Serial
cable which has the same pinout as the original Sun cable and should
work fine. The RJ 45 part of the cable is a ribbon and I assume is
shielded. I have also tried a cable which used standard cat5 cable and
that has the same issue.

Will let you know if the flow control makes a difference. Sun
recommends no flow control ...


Re: Netra X1, Corrupt text received via serial connection

Postby James » Sat, 20 Aug 2005 06:46:53 GMT

Hi Yves,

I tried setting flow control to hardware and the console became
unresponsive. setting back to none or software gets response back but
the replies are still scrambled. I would add the commands I type are
recognized by the server, e.g. I can test the fault lights etc. it's
just the display that is semi-scrambled.

Thanks

It sounds to me like you have an "stty sane" command in /etc/profile or
/etc/login.  Or as I like to call it "stty INsane", as it's a very old
stty setting that sets 9600, 7, E, 1 and wreaks general havoc on the
console screen.

But then again if you are seeing this at the LOM, perhaps not.  The
telltale sign of this is typically that the OBP output looks fine, but
as soon as Solaris starts up, the screen turns to garbage.

Well, anyway, just an idea.

Perhaps it's time to check again and be certain that the cable you're
using is wired precisely like a Sun one -- I can imagine something like
what you're seeing if a couple of the handshake lines were crossed.

Hi Darren,

It starts out like that but does seem to get worse as it goes,
especially if I do "poweron" and boot the server. My problem is that I
don't have access to the os over the network as the machine is second
hand so I need to re-install the os.

I've checked the cable again and it matches the Sun spec....


I'm also able to connect to my sparc 5 with no issue (albeit with a
null modem cable and not the RJ45 -> DB9).

Thanks,

James.

I tried removing a line from /etc/profle on my linux server that
contained stty sane ... but no difference :( corruption is always on
the Lom prompt and gets worse if I poweron.

The server does respond to commands it just seems as if something is
corrupting the display that comes back to the console..

FWIW, we have had something similar on three T1/V120 systems (which are similar
to the X1). In each case the LOM output was fine, and the system seemed to
accept commands, but output from the OBP and the OS was corrupt, with occasional
meaningful strings of a few characters buried in lots of junk. We were able to
connect OK to similar systems using the same cable, so it was definitely the
system itself to blame. In each case Sun replaced the M/B.

1.netra x1 serial console multi user login

hi there
on my netra x1 configure on the boot prompt to use seriala for in/out
is can succesfully login in single user mode and acces the machine
but if i switch to multiuser mode (exit/ctrl-d) apparently the tty settings
change in such a way that a lf or cr gives a new login prompt but
trying to login with a username (eg.root) gives an emptyline and the
login prompt again.

i tried every possible option in /etc/ttydefs and /etc/inittab and
basically am stuck getting this machine accessed after single user mode

any suggestions?

2.Text between PCs via serial connection

I am trying to do something VERY simple in concept.

All I want to do is connect two PCs by RS232 serial cable (cross
cable), start up the Linux (Unix) console and be able to type messages
to each other.

There are two scenarios:

1) Two Linux machines, in which case I would like to just use the
console.

2) A Linux machine connected to a Windows XP machine.  In this case I
would like to use the console on the Linux machine and a terminal
program on Windoze, such as HyperTerminal or Tera Term.

I would just like to send messages back and forth, chat-like, such as
"How are you?" and "I am fine".

I know this sounds useless and antiquated, I just want to do it for
study.

4.Netra X1 - Can't open boot device

Hi,


I'm rebuilding a Netra X1 with Solaris 8 2/02.....


I can build it off the network, and the build goes successfully.
However, when I reboot, and the box tries to boot from disk, it gives
me the following:


.....
Boot device: /pci@1f,0/ide@d/disk@0,0   FIle and args:
Evaluating: boot disk

Can't open boot device

......


and then it tries to boot from the network again. Any thoughts? The
hardware is good, I just can't seem to point it to a good boot device.
Please help.

- Thanks,


Todd
