Typically I get a response within...

Remote server mount slow - NFS

Hi, Following my last post I've mounted the remote server on my local server. However copying files from this mounted server is increadbily slow. If I copy files using rcp it's very fast so I assume there must be a setting somewhere? Any help appreicated. Thanks

file writing over nfs very slow

Hi guys, I am trying something. I wrote a simple shell program to test something where continuous while loop writes on a file over the nfs. The time taken to write "hello" 3000 times take about 10 sec which is not right. Ideally it should take fraction of seconds. If I write on the local disk, it...

vconfig

VCONFIG(8)						      System Manager's Manual							VCONFIG(8)

NAME

       vconfig - VLAN (802.1q) configuration program.

SYNOPSIS

       vconfig [lots of long options]

DESCRIPTION

       The  vconfig program allows you to create and remove vlan-devices on a vlan enabled kernel. Vlan-devices are virtual ethernet devices which
       represents the virtual lans on the physical lan.

OPTIONS

       add [interface-name] [vlan-id]
	      Creates a vlan-device on [interface-name]. The resulting vlan-device will be called according to the nameing convention set.

       rem [vlan-device]
	      Removes the named vlan-device.

       set_flag [vlan-device] 0 | 1
	      When 1, ethernet header reorders are turned on. Dumping the device will appear as a  common  ethernet  device  without  vlans.  When
	      0(default)  however,  ethernet  headers are not reordered, which results in vlan tagged packets when dumping the device. Usually the
	      default gives no problems, but some packet filtering programs might have problems with it.

       set_egress_map [vlan-device] [skb-priority] [vlan-qos]
	      This flags that outbound packets with a particular skb-priority should be tagged with the particular  vlan  priority  vlan-qos.  The
	      default vlan priority is 0.

       set_ingress_map [vlan-device] [skb-priority] [vlan-qos]
	      This  flags  that  inbound  packets  with the particular vlan priority vlan-qos should be queued with a particular skb-priority. The
	      default skb-priority is 0.

       set_name_type VLAN_PLUS_VID | VLAN_PLUS_VID_NO_PAD | DEV_PLUS_VID | DEV_PLUS_VID_NO_PAD
	      Sets the way vlan-device names are created. Use vconfig without arguments to see the different formats.

       NOTES  VLAN will use Broadcom's NICE interface when the network device supports it. This is necessary, since usually the hardware of  these
	      devices  already	removes the vlan tag from the ethernet packet. The set_flag option on vlan-devices created on such a physical net-
	      work device will be ignored.  Dumping the network-device will show only untagged(non-vlan) traffic,  and	dumping  the  vlan-devices
	      will only show traffic intended for that vlan, without the tags.

FILES

       /proc/net/vlan/config
       /proc/net/vlan/[vlan-device]
