Re: Hipersockets and DB/2
When DB/2 starts it (via smoke and mirrors) communicates with TCP/IP and issues a gethostid() request. In the tcpip(profile) configuration I did not have a primaryinterface parameter set and therefore the system defaulted to the first interface found in the Home stanza which was my hipersocket definition. My fix was to assign primaryinterface lcs0 sans quotes which points to my OSA and the external world and to change the order of the hosts to have the primary adapter first. Everything is fine now. -Original Message- From: Gianfranco Ciotti [mailto:[EMAIL PROTECTED] Sent: Thursday, April 14, 2005 12:05 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: Hipersockets and DB/2 I'm not very exert, but error seems that z/OS tries to resolve the host name of 192.168.1.68 machine but faild.

It's possible the module requires another module to be loaded first. If so, depmod -a to rebuild the dependency files, followed by a modprobe command (_not_ insmod) might do the trick. If not, I would say that the module wasn't compiled against the version of the kernel you're running, even though it is labeled as such.

OpenMosix update
There's a new OpenMosix out, that moves a great deal of the patch from kernel to userspace. http://freshmeat.net/projects/openmosix/? branch_id=21918release_id=193392 Most notable is that this should make a PPC port much easier. It's been my experience that if you can build it on both PPC and Intel, then a zSeries or S390 port is usually pretty straightforward because the word size and endianness issues have been worked out and those parts where it makes a difference are usually pretty cleanly factored out.

Hipersocket Frame size
Does anyone have any suggestions or guidlines on selecting a frame size in the definition of hipersockets ? I did read in the zSeries Hipersockets that the default Frame size is 16KB, compared with a maximum of 9KB for a Gigabyte Ethernet. But Hipersockets can also be defined as 24, 40 or 64KB. The selection depends on the data characteristics transported over a Hipersockets, which is a trade-off between performance and storage allocation. I want the best performance so what information do I need about the data to determine what frame size to define, and how much storage will I use if I define as 64KB ? All I have right now is that a client wants to transfer large amounts of data between z/OS and Linux but I don't have any details about how large. Is this main storage taken out of the total available on the processor or does it require more storage for each lpar to accomidate the hipersocket definitions ? I appreciate any suggestions.

Re: Can I make LVM by 1 DASD?
You can split up the DASD into equally sized minidisks and if you stripe the LV, then Linux will initiate multiple I/Os across howewever many physical volumes (minidisks) you have in the group. Depending on how many paths there are to the mod-27 device, there may be a performance benefit(?).

I A passphrase is a password to access your private LOCAL key. The passph is used locally to access your local (on your PC) private key. A cracker with only the passph will get nowhere (as opposed to password authentication, where the password is all he needs). He has to have both the passph AND the key (which means he will have to crack your local PC to steal it) which is stored in your local computer. The authentication (server side) is done by using the private key (which is encrypted locally with a passphrase). For added security you can also have your key on a physical smart card (in that case you need a card reader on your PC). Then a cracker will need both your card and the passph.

Re: Really silly SSH question.
Many systems administrators do _not_ enable logging in via SSH with passwords. Key pairs are required. If you used a good passphrase, you've gained more security. A good passphrase will be almost 100% impossible to guess or brute-force. If you wish, you can change the passphrase on your private key, and never have to sign in to any other system to do it. (Most people never do this, but it is possible.) You can create separate key pairs for various systems. It's not required, but some people like the idea. If you have a number of people that need access to a particular userid for some reason, if they have key pairs, each person can log in with their key pair, and never have to know what the password on the account is (or what each other's passphrase is). The list goes on. In general, a key pair with a really good password is much, much more secure and flexible than a password.

Re: Really silly SSH question.
I see a flaw in your logic here. If you don't want to type anything to access a remote system then your local computer needs to store all the information needed to access the remote system. Anyone that has access to your system can steal this information. If you don't want to store this information then you will need to type something every time. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of McKown, John Sent: Thursday, April 14, 2005 11:28 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: Really silly SSH question. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Rod Clayton Sent: Thursday, April 14, 2005 1:24 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: Really silly SSH question.

I see a flaw in your logic here. If you don't want to type anything to access a remote system then your local computer needs to store all the information needed to access the remote system. Anyone that has access to your system can steal this information. If you don't want to store this information then you will need to type something every time. Hum, I guess I didn't say that very well. My comment on the use of the passphrase was more how is a passphrase more secure than a password? than I don't want to type a passphrase. That has been answered. Another person indicated that the passphrase is only used LOCALLY and not sent to the server onto which I am logging. From more reading, apparently what is sent to the server is a one time cert or some such thing. So somebody intercepting that wouldn't be able to access the server. I'm learning, albeit slowly. Right now my private key file is on a USB flash drive, which is on a chain around my neck. The file is definitely NOT on my Windows desktop at work!

What is the problem?
You need to create a static /dev/console node. I think it's a
character device, major 5 minor 1. Also, your DASD spec will have
changed. Instead of dasd=150-155 or whatever, it'd be
dasd=0.0.150-0.0.155. Don't forget to rerun zipl.
Further, there are some changes to the chandev layer to get your
network devices working again with the new group devices stuff.
I did that with the creation of a file /etc/groupdev, and the following
script (/etc/init.d/groupdev.sh):
#
# groupdev.sh S/390 module initialization parameters
#
# Must run before networking but after udev.
#
# Version: @(#)groupdev.sh 0.0-0 27-Apr-2004

#

# Loop over lines in /etc/groupdev

while read type rest
do

modprobe -k ${type}

}/group
echo $4 /sys/bus/ccwgroup/drivers/${type}/0.0.${1}/online
;;
esac
done
echo done.
) /etc/groupdev
: exit 0
And /etc/groupdev contains:
# format is:
# type rest
# type is qeth or another grouped device
# qeth is the only one I know about right now.
#
# for qeth, rest is
# read-device write-device data-device online

# and online is 1 or 0 for whether the device should be

Hope this helps.

Re: Really silly SSH question.
For added security you can also have your key on a physical smart card (in that case you need a card reader on your PC). Then a cracker will need both your card and the passph. This is a great way to use small-size USB memory drives, BTW. If you're clever about it, you can also store other personal configuration files on the same drive, making it easy to move your settings with you. -- db -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: Really silly SSH question.
Instead, I must use a Passphrase. What have I gained? John ... I'm not a security expert, but I believe those who are would put it something like this: You have more security now because there are TWO things required for you to connect to the remote system: what you KNOW (same as before, but perhaps now longer) and what you HAVE (private key). A traditional password is what you KNOW. A passphrase is not a lot different, as you point out, except that it is much longer in practice, and that's a Good Thing. The private key is a what you HAVE. It's like a SecurID card. It's a VERY VALUABLE thing. Protect it! As others have said, with no passphrase on your private key (your local key to PuTTY or your secret key of the pair) you can automate signing on, and that's useful, but dangerous. But WITH a passphrase, someone acquiring your secret key has a much more difficult time breaking in. You want to avoid that theft, but you have some protection in case it happens. The public key matches your private key but does not expose it. The public key can be swiped from the remote host, and you have lost nothing. (Except that there may have been a compromise of that system which allowed the rogue to get that key. But that's really a different problem.) Someone taking your public key could arrange for you to get access to THEIR system(s), and that's no win for them. This is subtle: Traditional password sign-on requires that some secret must be shared between you and the target system. That's a secret which can be taken by a bad guy. Public key is a HUGE improvement, reducing the value of stealing info from the target system. So there are two things: what you KNOW and what you HAVE, and that's a big improvement. Further, the KNOWn part is removed from the system(s) you're signing onto. (That is, the passphrase is never stored on any target system, but is always local to where the secret key (private key) is held.) Does this help? -- R; -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

What is the problem?
You need to create a static /dev/console node. I
think it's a
character device, major 5 minor 1. Also, your DASD
spec will have
changed. Instead of dasd=150-155 or whatever, it'd
be
dasd=0.0.150-0.0.155. Don't forget to rerun zipl.
Further, there are some changes to the chandev layer
to get your
network devices working again with the new group
devices stuff.
I did that with the creation of a file
/etc/groupdev, and the following
script (/etc/init.d/groupdev.sh):
#
# groupdev.sh S/390 module initialization
parameters
#
# Must run before networking but after udev.
#
# Version: @(#)groupdev.sh 0.0-0 27-Apr-2004
[EMAIL PROTECTED]
#
[ -f /etc/default/rcS ] . /etc/default/rcS
test -f /etc/groupdev (
# Loop over lines in /etc/groupdev
echo -n Initializing ccwgroup devices...
while read type rest
do
case $type in |\#*)
continue
;;
esac
case $type in qeth)
modprobe -k ${type}
set -- $rest
echo 0.0.${1},0.0.${2},0.0.${3}
/sys/bus/ccwgroup/drivers/${type
}/group
echo $4
/sys/bus/ccwgroup/drivers/${type}/0.0.${1}/online
;;
esac
done
echo done.
) /etc/groupdev
: exit 0
And /etc/groupdev contains:
# format is:
# type rest
# type is qeth or another grouped device
# qeth is the only one I know about right now.
#
# for qeth, rest is
# read-device write-device data-device online
# where the devices are four-digit hex
addresses,
# and online is 1 or 0 for whether the

#on- or offline

Hope this helps.
