Re: [CentOS] Yum cant find kernel-pae

2014-09-09 Thread Bob Metelsky

its 64 bit - (first post)

actually this is a dell 9100 (desktop)

I had 2 pairs - 2gb each of ram different manufacturer
actually I have 3 pairs of 2gb - any combination has the same results in
memtest

1 pair in white
1 pair  in black

boots without memory beep errors
memtest fails badly on any test with 8gb
bios sees the memory

I was running 2 2 gb originally
now I have 4 1gb - so each slot is used and it tests perfect

Basically this is a lab setup for a 4 node hadoop cluster. This is the head
node and needs the most ram - Id really like to get 8 but Ill live with 4
 (if I have to)

So should my kernel support > 4gb? see below

Thank you all for your time!

uname -a is in the original message.

See to be a problem with the board

any memory I put in the black slots will fail with memtest..

damm

I was hoping if the pc booted up with about that annoying memory beep - I
was ok... I memtested and it failed

Its dual channel and they  are in the right spot, I reseated them

1 pair in black
1  pair in white

So are you guys saying my kernel should be supporting more than 4gb?

[CentOS] Any information on targetcli (fcoe) for centos 6? Close to end of my rope

2014-05-01 Thread Bob Metelsky

Guys, Im trying very hard to get a poc iscsi target/initiator working
between 2 centos 6 machines. The targetcli seems buggy as hell - meaning it
does not look updated for the current version of centos or other
distributions output

some output -

 notice the 2011 year

and I dont have the iscsi directory.

 It seems commands can only be issued out of the corresponding directory...
I want to disable suthentication ie

/iscsi> set discovery_auth enable=0

Unknown configuration group: discovery_auth


I dont have the ISCSI directory!



OMG!


apparently this is the install for targetcli...

fcoe-target-utils.noarch fcoe-utils.i686


Is there any relatively direct documentation on how to set this up?

I wasnt to use iscsi as a san replicator for oracle ASM and NOT use
openfiler. I want to do this just from centos 6 to centos 6

this is very strange

I ran your flush command.. worked untill reboot

I  came across this article

Basically tell me  how to save a wide open rules file - I did this and
behaved like the doc describes

This is what I have now

I don't understand what or why  iptables is being called?

 I believe anything in /etc/rc.d/init.d/* will get run on startup. If I
move those files out of there - obviously the command wont work - but I
need to understand whats going on


I want status to tell me OFF

 /etc/rc.d/init.d/iptables status

[CentOS] Firewall will not disable - stumped!

very perplexed here - I need to turn off iptables. Ive tried

service iptables save
service iptables stop

chkconfig ip6tables off

Note -->  192.168.122.0/24 is NOT my network, I just want the status to
tell me iptables is NOT running

What else can I look for??

Re: [CentOS] Basic Network question pinging different subnets

2007-11-16 Thread Bob Metelsky



Any ideas why this is happening? I dont have a firewall on the 10.54 
address,


presumably, the windows machine is connected to the 'eth0' network 
that the centos machines are connected to?


how exactly do you expect the packets to get from there to the other 
network?  the windows machine has been instructed to forward all 
unknown packets to 10.54.7.1, which presumably is some other sort of 
router...   chances are, said 10.54.7.1 has no clue where 10.54.0.xxx is.




Ya-  I see - your right the router is 10.54.7.1  The rest of the network 
switches are  hubs off of that (all still 10.54.7.)


this private network is truly private  (independent to the 2 computers 
connected) in other words they are off the network, their traffic oesn't 
go through a switch.


I didn't give this enough thought 

the fact is I dont need to connect to the 0 address directly from the 
windows machine. The 0 address is only for private network between the 
database servers...


I was just curious that I couldn't ping them, I thought ping (and the 
port scanner) should magically find them (like dns) ...


solution 1) configure a linux computer to do 'ip forwarding', and give 
the windows machine a route like...


   C>  route add 10.54.0.0 mask 255.255.255.0 gw 10.54.7.2

or, solution 2) configure the router at 10.54.7.1 to have a route to 
this other network.



if both networks are on the same hub/switch, then I can only ask... WHY?


Thanks for the insight,

Bob

Re: [CentOS] Basic Network question pinging different subnets

2007-11-16 Thread Bob Metelsky


Im a dba not a network guy... :)
Well ok I know there are technical "reasons" why this doesn't seem 
to "work"


But -  why can I ping any other ip address   ie Google
64.233.167.99

Ok I guess thats "resolvable" and not private. My thinking is ping 
should try and  "find" the address


Maybe I need a type of local dns...(??)  How does one avoid  manually 
adding "routes"


my port scanner - I give a range 10.54.0.0 - 10.54.7.55, Im thinking it 
should try all addresses in between and it only gets the ones on 10.54.7.0


The comment below sounds like what I need... thanks!

"

c:\> route add 10.54.0.0 MASK 255.255.255.0 10.54.7.16

But this should give you access on both 10.54.0.2 and 10.54.0.3

"

C:\>route add 10.54.0.0 MASK 255.255.255.0 10.54.7.16

C:\>ping 10.54.0.2

Pinging 10.54.0.2 with 32 bytes of data:

Reply from 10.54.0.2: bytes=32 time<1ms TTL=64
Reply from 10.54.0.2: bytes=32 time<1ms TTL=64

My purpose is to have a private network between database servers (oracle 
rac) where only specific traffic is allowed, and it works that way, I 
was just surprised that I want able to ping the 0 subnet.

So I need to add the route...

Thanks for everyones feedback. Hopefully I can contribute 
something....in the future

;-)

Yes ! You have to learn how works IP networks :-)
IP is wild and wide :-)

you can try this on your windows :

c:\> route add 10.54.0.2 MASK 255.255.255.255 10.54.7.2

OR

do the same on your router at 10.54.7.1

OR (depend on how your linux box is configured)

c:\> route add 10.54.0.0 MASK 255.255.255.0 10.54.7.16

But this should give you access on both 10.54.0.2 and 10.54.0.3

OR if routing is enable on 10.54.7.2

c:\> route add 10.54.0.0 MASK 255.255.255.0 10.54.7.2

should also give you access to both 10.54.0.2 and 10.54.0.3


You just have to understand the first one other are just to spread out
my IP knowledges.
Ops, the last one is sometime useful to configure a device on another
IP range, without reconfiguring your IP.
Like when unpacking a new router with IP 192.168.123.1

Regards.

[CentOS] Wits end! ndis got me - give me sanity with my wireless!!!

2007-10-26 Thread Bob Metelsky


All - desperate plea for help here.

Overview Centos 4.5   Kernel 2.6.9.55.0.9.EL with source  dell Latitude 810

Im totally at my wits end... Ive tried like mad to get ndiswrapper to 
work for my lynksys  WPC54GS wireless card. No matter what I try ndis 
gives some kind of error on installing the module  after about a dozen 
attempts 8 kernels, and 5 days- I  finally GAVE UP!


unreal

So, I install the http://www.linuxant.com/company/  ever$ion (im not 
above paying $20 to save me a few wasted days) this program  dosnt have 
a problem detecting the card, making the lights blink, I cane see the 
access point using iwlist scan, I know precisely what the essid is, as 
well as the encryption key, BUT now the stupid thing cant get an ip 
form my dhcp server!!


Please help - some kind of sanity check, Im ready  to jump out the 
window!! ;)


Im up for ANY solution, I can install kernel source.. ndis bla... I just 
need some thing that will work. At this point i have an incredibly low 
opinion of the developers of ndis - that shouldn't not release such 
stuff. Ive followed the dcs to the letter and either the kernal compile 
puked... or ndis chokes on some flyshit in a function unreal!


Anyway I  do have this working on the same laptop but I did it about a 
year ago and cnat find the 1.37 version of ndis. At tthis point ndis is 
just too picky


Anyone???

Thnaks
Bob
