landscape laužia kompą

landscape taip užkrovė Input Output, kad teko jį removinti sudo apt-get remove landscape-common.

vėliau reiks išspręst tą problemą, nes šiaip tas landscape tai mielas, nors ir nelb saugus...

toshiba serv

įdomumo dėlei prijungiau prie landscape. su landscape per web naršyklę galima centralizuotai valdyti ir stebėti daug kompų.

drive speed test

pasiskolinau seagate hdd 160gb sata. sujungiau su savo 250 gb sata samsung. Įjungiau gigabyte m55s-s3 motininės nvidia raid 0 - stripping raid, ty. duomenų blokai paskirstomi po abu diskus, OS mato kai vieną. Mano atveju - 300gb hdd. Atlikau testus, palyginau su pata (geriau būtų sata) wdc 80gb disku. papildomai atlikau ir abiejų asus 901 diskų testuką

copy files using scp

Copy Files Securely using SCP

Another common need is to be able to copy files between servers you are administering. While you could set up FTP on all of the servers, this is a less-than-ideal and potentially insecure solution. SSH includes within it the capability to copy files using the scp command. This has the added benefit of copying the files over a secure channel along with taking advantage of any key-based authentication you might have already set up.

To copy a file to a remote machine use the following command

scp /path/to/file user@remotehost:/path/to/destination

If you need to copy from the remote host to the local host, reverse the above command

scp user@remotehost:/path/to/file /path/to/destination

if you need to copy an entire directory full of files to a remote location, use the -r argument

scp -r /path/to/directory/ user@remotehost:/path/to/destination/

If you are transferring logfiles or other highly compressible files, you might benefit from the -C argument. This turns on compression, which, while it will increase the CPU usage during the copy, should also increase the speed in which the file transfers.

Use the -l argument to limit how much bandwidth is used. Follow -l with the bandwidth you want to use in kilobits per second. So, to transfer a file and limit it to 256 Kbps use the following command

scp -l 256 /path/to/file user@remotehost:/path/to/destination
