Bad throughput quad gigabit ether X4444A

Hi all,
I am not seeing the throughput I expect from this gigabit ethernet interface:
Running ttcp:
# ./ttcp -r -n1000000 -l1500 -s
ttcp-r: nbuf=1000000, buflen=1500, port=2000
ttcp-r: socket
ttcp-r: accept
ttcp-r: 2.4user 26.4sys 1:14real 39% 0i+0d 0maxrss 0+0pf 15931+17525csw
ttcp-r: 1500000000 bytes processed
ttcp-r: 28.9001 CPU sec = 50686.5 KB/cpu sec, 405492 Kbits/cpu sec
ttcp-r: 74.0193 real sec = 19790 KB/real sec, 158320 Kbits/sec
# ndd /dev/ce adv_autoneg_cap
1
And of course the switch is in autoneg. As you can see in the ttcp output i am getting like 15% of the theoretical throughput which is bad. I get at least 80% with other servers.
Any idea/suggestions what might be wrong?
Thanks,
Max

3602i Errors in log, bad throughput

I just acquared a 3602i. It was running lightweight, but I changed it to autonomous.
From the start I notced absomal throughput when only 10-20 feet away, bouncing from 0 to 7 Mb/s when using iperf over a 30 second period. If I used the same client on my 3502, I get a solid consistant throughput of 37 Mb/s.
When I looked at the logs, I noticed the following section:

Those errors are none that I have seen before.
Ideas? I have an idea what is wrong, but I wanted some feedback before suggesting anything. The performance is bad with more than just this specific client that I'm testing with.
Thanks

I'm running the latest autonomous code (July 31st 2013) - ap3g2-k9w7-xx.152-4.JA1 , but I was also running an old one and had the same errors as I originally posted.
I finally got around the testing again with my two APs

> 3602i only should work in lap mode, what IOS you used to covert it to AP mode?
Autonomous code has been released by Cisco, it's available from the support/download page. While I totally understand these classes of lighweight radios were meant to only be used this way and that autonomous was for surveying with a limited feature set, my 3502i has worked flawless for 4+ months.
Also, I also don't think the errors I'm seeing are a result of using the Autonomous mode, these seem like much lower level of errors that woudl impact your ability to even do a proper suvrey.

Solaris 10 x86 goes to reboot mode after installing Sun x4 PCIe Quad card

I have an x4200 server installed with solaris 10 x86 11/06 OS. After installing the OS it comes up fine.
Now, When I install an SUN x4 PCIe Quad Gigabit Ethernet card on PCI slot 0 and on the power up server does not comes up. It gpes into the reboot mode.
bash-3.00# uname -a
SunOS server1-1 5.10 Generic_118855-33 i86pc i386 i86pc
Does any one has face this issue..

Solution found:
First tried to login using "console login" when solaris booted up, before the desktop login window appeared. Then, run command "kdmconfig", changed the video device to X86 VESA compatible device, which is from the x86 driver and porting kit for solaris, then test/save and exit. After that, reboot the system. Now it is working, not perfect though (due to my old monitor) :)-

Gigabit Ethernet over SDH

Hi all,
I am trying to get a new Gigabit Etherent link up from a service provider. We have 2 GSRs with 1000 Base SX Gbics connected to this providers (Nortel equipment) equipment. All our equipment has been tested, looped etc so I believe the problem lies with interoperability between our Gbics and the Nortel GE over SDH equipment.
Does anyone on this list have experience of GE over SDH(Sonet)? If so are there any issues I should be thinking of?
Any direction/advice would be appreciated.
Thanks
Eoin

Do you know the specific Nortel equipment is? Is it Optera ? Which model?
Do you know the specifc model number of the blade / interface?
Any additional information you can offer could help alot.
Thanks
Scott

Can I use old Mac Pro with new iMac?

I have a Mac Pro (Pre 2007) running on 10.6.8 that is ok for now, but experiencing some degradation in performance. I have 4 drive bays full and memory maxed out. I am looking for a desktop solution that would allow the option to have the latest OSX (such as the latest iMac) and access this old Mac Pro still. Is this possible?
If so, what are some of the caveats?
SoftwareEx: CS6 is compatible with new OSX, but will files saved on new computer still be accessible on old computer?
Access to files
NetworkCurrently using older version of Airport Extreme for home office setup
Any insights would be helpful! I hate the thought of this old workhorse turning into nothing more than an external hard drive, but it is not upgradable to the new operating system.

It sounds like what you want to do is create a simple peer network so you can use the Mac Pro as a storage unit.
This is easy to do, just connect the two with an ethernet cable and log on using the logon and password for the system you want to access. In the general case, this is a bad idea since you you have unrestricted access but you own both machines so security is a very low priority.
Caveats:
     The OS version will determine what apps a machine can run.
     Data is just data as long as both systems use HSF+ or some other common file system.
     Airport may or may not work... but a hard wire will always get it done and transfers data a lot faster.
You almost never get to have it ALL your way when mixing generations of systems, but if you keep it simple it works well. I've had a peer network with 4-6 systems running in my house since the turn of the century. Most Macs support 1000 baseT (gigabit ether) so data transfers up to 80-90MB/sec are easy.

please help!

I am pretty sure it doesn't work with Firefox.
I have been getting the same problem as you with Internet Explorer. "The adress is valid but will not connect" kind of error.
Having to reboot the whole router (messing 2-3 other connections) to adjust some settings is quite frustrating, I know.
Let me know if you find what causes this and how to solve it

Added WRT54GL to Roadrunner, no internet, I've tried everything!

I installed my Linksys wireless router to my Roadrunner connection so I can get all of my 3 computers online. I can hook one computer directly to the modem and of course it can get online, but I get nothing with the router added into the mix. I've searched here and on other forums for at least a week trying to get this to work, but no luck. I know this topic gets brought up A LOT so I apologize, but I promise I've searched before making a new thread and none of the solutions are working.
Quick overview:
WRT54GL wireless router (Tomato 1.21 firmware)
Motorola SURFboard SB5101 modem
- Modem -> router WAN port
- router WAN port set to DHCP
- MTU set to 1500
- Router IP 192.168.1.1 (default)
- Modem IP 192.168.100.1 (default)
- LAN set for DHCP (range 192.168.1.100-253 *255.255.255.0)
- router Ethernet port 1 -> Host (only 1 comp connected at the moment)
- Computer set to DHCP
- Cloned computer's MAC address to WAN
As long as I power up the modem first and then the router, the WAN will connect just like it should using the IP/Subnet/DNS/etc supplied by the modem. The weirdest part is that I can bring up the console for both the router and the modem, and I can also ping the modem... so everything appears to be set up properly on my end, but for whatever reason I simply can't get outside of the modem to the internet. In fact when I try to go to a website like google.com for example the browser says "Waiting for google.com..." You'd think that if there really was a problem getting to the internet it would say "Looking up google.com", but maybe not, whatever. I know for sure that I don't have any software/settings on my PC messing things up.
Here's the basic steps I used to set everything up:
1. Connect modem to WAN port and computer to Ethernet port 1
2. Set router WAN port to DHCP, Save
3. Manually set WAN's MTU to 1500, Save
4. Clone PC's MAC address to WAN, Save
5. Set LAN ports to DHCP, Save
6. Power down modem, router, and PC... let sit for a few minutes.
7. Power up modem, wait until completely done
8. Power up router, wait until completely done
9. Power up PC, enable LAN connection
At this point the WAN settings in the router's console show the proper MAC, IP, subnet, gateway, DNS's, and MTU. As I said before, I can successfully ping the modem and bring up the modem's console so there's obviously no problem communicating to the modem...it just won't let me out on the internet!
Think it has something to do with the LAN's subnet being 255.255.255.0 and the WAN/modem being 255.255.252.0? Do they both need to use the same subnet mask or does it even matter? Do the first 3 octets of all the IP's on the network need to be the same with just the last octet being unique?
Aside from that stuff I'm all out of ideas... I got this exact setup working with my previous cable ISP (non-Roadrunner/Time Warner) with almost no configuration at all and I'm seriously about to go to another ISP if I cant get this to work.
Any help is greatly appreciated! Thanks folks.
(and also thanks for reading this rather long post )

Lots of stuff here... not sure what this "tunnel adapter" stuff is, the one to look for is Marvell
Additionally, the reason I cloned the MAC address and manually set the MTU is because I read in several how-to's about connecting Linksys WRT54xxx routers to roadrunner that those steps were necessary. I have tried the process without doing both of those things, but it doesn't change anything.

Ultra 10 not writing to path_to_inst

Hello I have a Ultra 10 system, Solaris 8, 64-bit. I installed an Antares gigabit quad card and for some reason its not writing to the /etc/path_to_inst file. I installed the package and the package is showed doing a pkginfo. Issueing the command prtconf | grep ANTR it shows the instance numbers. Doing a reboot, the drivers becomes de-attached. In order to get the card to work properly I have to manually add the driver using /usr/sbin/add_drv -i. Has anyone had this problem with not being able to configured quad gigabit ethernet devices before. I installed two standard hme sun pci nics into the machine and they configured properly and wrote to path_to_inst file automatically. Please help.

The problem you are having is probably a third party issue that will take either Antares or Sun to fix for you. There seems to be quite a few posts concerning these cards and I still have no practical experience of them :-(
However, if you have a command process that works, just put it into your startup scripts and `bob's your uncle`, no more having to do it manually every time. I would probably configure your gig at the same time!

Slow to connect to Mac share - file and screen

I have a few Macs on a network, with wired and wireless connections. I'm finding that I can connect to some of the machines quite quickly - from time that I click on the machine in the Shared area of the sidebar to when I see disks appear, or from when I click on screen sharing to something appearing, is fast. This is true for a PowerPC Mini running 10.5.x - takes 1 second for disks to appear.
At the same time, I have a MacBook Pro, 2.8 GHz, running 10.6.6, where it takes as much as 15 seconds for disks to appear or screen sharing to start. This happens with wired or wireless connections to the machine - I can be wired through a gigabit switch between that machine and another fast machine and still takes 10-15 seconds. This has been occurring for some time, and was present before and after the 10.6.6 patch.
Once I am copying data between machines, things seem to run quickly. So it seems mostly to be at the initial connection. If I go to sleep on a machine that is already connected to this MBP, wake up, then click on the MBP again, even though have mounted shares it still took 15 seconds to re-display the shares.
Any idea how I might diagnose and fix this?
Thanks,
Alex

There is no external drive on this machine - and I verified that the disk is awake. Not the issue.
The wired test was done between Macs on the same gigabit ether switch.
Another clue - I've found that when playing Starcraft 2 on this machine, this machine is the last to load vs others in multiplayer. I'm playing side by side with another machine on an older MacBook Pro, slightly slower, and that one always loads faster.

Running concurrent Application Server in same processor

Has anyone done any benchmark testing with running multiple concurrent application server?
I need to run 70 Application Servers 10g on the same processors and I need to know if there are any limitations or any best practices?
Any suggestions or recommendations will be greatly appreciated.
I have the following requirements:
Hardware:
RAM
64 GB
CPU and cores and CPU speed.
C8 Core 1.2GHz UltraSPARC T2 processor
HD capacity
2x146GB SAS
Server Name or type
SUN Enterprise T5220
5. Network:
Network Speed
5 Containers will share bandwidth of one Gigabit Ethernet NIC, giving theoretical bandwidth of 200Mb/s to each container on average
Network Card and Network Drivers
Internal Network Interfaces - Type: 10/100/1000; Quantity: 4
External Network Interfaces - Type: x8 PCI express Quad Gigabit Ethernet UTP low profile adapter; Quantity: 4
Software Stack:
OS version and OS type
Sun Solaris 10 US

Thanks for you response.
For the purpose of our discussion here is what we are looking at:
There is going to be only a single machine a T5220 Sun Server loaded with Solaris 10.
1. This single machine will hold 70 concurrent applications server 10g.
2. Each application servers will have its own dedicated Oracle database in a seperate server.
Should this architecture hold?

DNS Questions

Got a couple of weird things going on. Using Postfix, in the mail log when someone sends an email, it states, Connected: unknown - 192.168.0.84.
Now everything works fine but it does not give the internal computer name only the IP. It's as if it cannot resolve the DNS. Also in the DNS log I have a couple of errors, one is 'local host name '@.' error and bad dotted quad error
anybody know of any way of getting rid of these.
Cheers

I note from your footer that you are running 10.3.9 server. Is this correct? So following is working from memory of this...
Inside Localhost zone: NS From localhost to @ and A record 10.15.6.1 to 127.0.0.1
(to others reading this, above description makes sense if you recollect the way 10.3 server configured DNS)
I have no idea why you have got an 'A' record linking two IP addresses or why this is in the localhost zone. 10.3 had a nasty bug in its DNS which sometimes corrupted the localhost zone. Can you post the contents of the localhost zone? To do this, open Terminal on server and issue "cat /var/named/localhost.zone" then copy and paste into your post. Do the same for "cat /var/named/named.local"
If you get an error about "no such file", issue: "ls /var/named" and post output (I cannot remember if 10.3 had different file names).
I also have a reverse lookup zone for 10.15.6.1 to 127.0.0.1 and vice versa.
This is also very odd.
If I wanted to resolve a workstation by FQDN and IP what record should I create and where should it go.
To create a map from mac99.salegrammar.co.uk to 10.15.6.99 (and vice versa)...
Enter zone for salegrammar.co.uk, add record type 'A', map from: "mac99", map to: "10.15.6.99". Tick the box to automatically generate the PTR record.

If your localhost and named.local files are FUBAR, and you want to replace them or just compare them to good ones, you can download default 10.4 ones (but best wait till you post existing contents)...

OEL 5.x on brand new Proliant DL-370 G6 hardware?

Has anyone yet installed OEL 5.2 or 5.3 onto HP's new Proliant DL-370 G6 hardware yet?
Specifically I need to know if the HP SmartArray P410 series SAS Raid Controllers, onboard quad gigabit ethernet NICS and the add-in NC370T dual port gigabit ethernet NICs are fully supported.
Also will the 64-bit version of OEL 5.x be able to see and utilize 64GB of RAM in this machine?

Has anyone yet installed OEL 5.2 or 5.3 onto HP's new Proliant DL-370 G6 hardware yet?Best check with HP to ensure they will support the hardware with this O/S; they should, but you never know.
Specifically I need to know if the HP SmartArray P410 series SAS Raid Controllers, onboard quad gigabit ethernet NICS and the add-in NC370T dual port gigabit ethernet NICs are fully supported.HP should know. I don't see any trouble reports about this server, however.
Also will the 64-bit version of OEL 5.x be able to see and utilize 64GB of RAM in this machine?No reason to think it won't. See the various options at http://www.redhat.com/rhel/compare/ for more info.

Distributed Audio Processing

Does this only work with G5"s? I'm looking at possibly upgrading to Logic Pro and I was really excited about Distrubuted Audio Processing but then I'd read something saying it only works on G5's. Is this true? Are there any other requirements?

Mmm, doesn't 'only' work on G5's, however, that is where you will see the most benefit, as there is 'some' overhead associated with the process.
It also says you need gigabit ethernet, however, it will work in hundred base, but the above statement applies also. See if can borrow a G5 and have a go with your Powerbook. It is easy to setup and doesn't interfere with the node system. Make sure you install the latest versions of Logic and the latest Logic Node on the node system (G5).
Note, you can also use a Firewire cable between the units for networking, should the ethernet ports already be taken. (the newest Dual Core macs now have two gigabit ether ports!)

Error codes for shared variables in Labview 8.5?

I am trying to use Shared Variables in Labview 8.5 to enable real-time loops (similar to some of the examples in "Using the LabVIEW Shared Variable", published Aug 28, 2007). I created it to hold the result of a 16-channel A/D converter (so a 16-element I16 array). To avoid losing samples, I used buffering, with a buffer of 5. To test this, I made a pair of VIs, one a producer that stuffs a 16-element I16 array into the shared variable "every so often" (controlled by a timed loop), and a consumer loop that reads the shared variable and does something with the data.
If I think of the buffered shared variable as a Real Time FIFO (as the article suggests it is), I was curious how I would know (a) when the queue was empty, and (b) if the queue had overflowed. Both are necessary if this is to be a practical means of exchanging data -- you want the producer and consumer to run more-or-less at the same rate, but only the producer is deterministic. The consumer needs to be able to run "faster" if it falls behind (for example, because it is writing data to disk), but you don't want it to read data from the shared variable if there's nothing there. [One can always read a shared variable, after all -- as the article states, it simply "holds" the last value written to it].
Snooping around, I discovered that there are "error codes" associated with the shared variable. In particular, a code of -2220 (FFFFF754) seems to signify an empty queue (or a shared variable that has not yet been written to), while a code of -1950678981 (8BBB003B) appears to be "buffer overflow".
Is this documented anywhere? Are there other "error codes" that would be helpful to know? Is there some rationale to these seemingly-random numbers? [It would help to develop code to utilize shared variables if there was a bit less "magic" and "mystery" involved].
For what it is worth, with a buffer of size 40, I could generate 16 I16 values at 1 KHz (simulating sampling from a 16-channel A/D at 1 KHz) and pass it to a consumer node that (a) read from the shared variable until it was empty, then (b) "went to sleep" for 20 msec (simulating "doing something else non-deterministically"), and not miss any data (because I could then empty the Shared Variable RT-FIFO, which should have been half full, before it overflowed on me). Not bad throughput -- I bet I could push it even higher.
Bob Schor

Hey Bob,
The errors are documented in the LabVIEW help:
Shared Variable Error Codes
Real-Time Shared Variable Error Codes
There are several error messages for buffer underflow/overflow depending on the settings of the network or RT FIFO buffers. In particular the -2220 and -2221 are useful for the producer/consumer use case. For example (as you probably know) the consumer can flush a variable using the error code (see the attached image).

WRT610N to TP-LINK SWITCH cannot ping printer on switch

I hope you can tell me what I have done wrong.
dslmodem ---> wrt610N ---->TP-LINK(5port) ---- HP 2600N printer, another to IOmega HD
I cannot see either the printer nor the HD. I cannot ping them.
The cables from the TP to the printer are blue, CAT5 cables. Does blue mean twisted pair?
The HP and IOmega have static IP addresses at 192.168.1.2 and 192.168.1.3 each.
The DHCP settings on the router allocate DHCP from 100-254 to avoid conflicts.
The firewall on the WRT610N is disabled.
Physical limitations permit only one CAT5 cable to the TPLINK box.
If I avoid the box and do this;
dslmodem ---> wrt610N ---->HP 2600N printer
I can ping it from both a Windows 7 and/or XP machine.
However, with the switch in place, I cannot ping it from the router nor any PC's connected to it. The PCs can ping each other.
Could someone please tell me what I am doing wrong?
Thank you in advance.

The device is a TPLINK TL-SF1005D unmanaged 5 port switch. No visible settings or buttons.
The address handed out on other side of the TPLINK is 169.254.138.233
My network is 192.168.1.*
Hmm. This does not bode well.
Should I set up a routing table entry to talk to this switch?
The wire from the router is hooked to port 1 on the switch. Should it not pick up the right submask, entry from the router?
Thanks for all your help?
