Restricting volume access to specific network interfaces
by Holland, William L 16 Jul '03

16 Jul '03

Is it possible to restrict access to volumes/qtrees/shares to specific network interfaces? For instance, I create a volume and/or qtree to host a database. I don't want it to be accessed via the onboard 10/100 connection, instead I only want it to be accessible by a dedicated GbE connection i.e. e4a.

gigabit nfs performance
by Dan OBrien 16 Jul '03

16 Jul '03

What can I expect for Gigabit NFS performance between my F630 NetApps and a pretty hefty Linux box, both running Gigabit network devices? My filer is running: NetApp Release 5.3.6R2: Sat Aug 5 09:40:44 PDT 2000 The Gigabit board is: slot 10: Gigabit Ethernet Controller e10 MAC Address: 00:60:cf:20:2b:2f (1000fx) e10: flags=300043<UP,BROADCAST,RUNNING,TCPCKSUM> mtu 1500 inet 209.41.211.225 netmask 0xffffffc0 broadcast 209.41.211.255 ether 00:60:cf:20:2b:2f (1000fx) I'm using a Transition Networks 1000Base-SX to 1000Base-TX Media converter into a Linksys 2 Gigabit port / 24 100BT port switch. The Linux box is running an Intel e1000 server card e1000: eth0 NIC Link is Up 1000 Mbps Full Duplex All wiring is CAT 5E. I mount the filer on Linux as: mlswna:/ on /backup/mnt/mlswna/rt type nfs (ro,timeo=14,rsize=32768,wsize=32768,nfsvers=3,addr=209.41.211.225) UDP, NFS3, 32K rsize. (Linux TCP NFS support is not quite ready for prime time.) I copied a 100MB file in under 10 seconds. That's around 10Mbytes/second. $ ls -l diskfile -rw-r--r-- 1 34726 34726 104857600 May 9 13:44 diskfile $ time cp diskfile /dev/null 9.85s real 0.00s user 0.31s system $ bs -c 104857600/9.85 10,645,441.6244 I would expect much better than this. The network/switch I'm on has little traffic. The only Gigabit use is the filer and Linux boxes. What other advice can you give me? What other knobs to turn.

NOTE REPLY TO phillipweah(a)indiatimes.com IF INTERESTED ATT: Liberia,a country in West Africa is presently torn apart by strife and armed rebellion.These upheavals have led to the intervention of the American government which has insisted that the incumbent president Charles Taylor,vacate his position and allow an international peacekeeping force to act as a transitional government. The embattled president Charles Taylor,has been offered political asylum by the Government of the Federal Republic of Nigeria, and he intends to grasp this lifeline that has been provided. The Government of the United States of America have clearly stated their intentions to investigate the finances and financial dealings of president Charles Taylor and have also threatened to freeze his personal accounts.In the light of these circumstances,the president has instructed me,his personal assistant to source for a foreigner who can take possesion and control of a large portion of his personal fortune which he has amassed over the period of his regime, which is stashed away in a financial institution in Europe. These monies amount to approximately four point five million euros (4. 500.000 million euros) Adequate remuneration will be provided for services rendered by you. It is important that you expedite action in this transaction if you are interested, because time is of the essence.Confidentiality is also of great importance. Thankyou Phillip Weah Personal assistant to the president.

virus scan on a network share changes Unix file permissions to 77 7
by Clawson, Simon 11 Jul '03

11 Jul '03

Hi, A user in France has run a virus scan, using NAV 7.5 across a network share to the filer. This resulted in no problems in the PC world, however, the files when viewed from UNIX have a 777 permission set. I tested this on a file on our filer here and did not see this effect. Has anyone else tried this? I know this is not the recommended way to scan the filer, and have advised the user of this.

RE: access same files via SAN and NFS
by Clarke, John L. (CIS) 10 Jul '03

10 Jul '03

Kerry, If its just a regular NetApp (not a SAN Netapp), you can put in a Fibre Channel card into the NetApp and connect it into a "tape backup" SAN so that you can use the SAN to switch in a tape drive to the filer. Very similar to just attaching a fibre-channel or SCSI tape drive directly to the NetApp. You could then use NDMP to back up the filer to the tape drive(s) over the SAN. This assumes that your TSM backup server supports NDMP. Works great for us.
