Connecting to Storage from Linux

storageN

  • The use of storageN within these documents indicates that any storage platform can be used.

  • Current available storage platforms:

    • storage1

    • storage2

Using mount

This was tested on Ubuntu 16.04 with mount.cifs version 6.4 which is part of the cifs.utils package

Install cifs.utils:

sudo apt-get install cifs.utils

Use the id command do find the local user’s uid and gid, optional:

id

uid=1000({local user name}) gid=1000({local user group}) groups=1000({local user group}),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),110(lpadmin),111(sambashare),119(libvirt)

Issue the mount command with proper options and credentials:

mount -t cifs -o vers=3.0,uid=1000,gid=1000,credentials=/tmp/.auth //storageN.ris.wustl.edu/${VOLUME_NAME} /mnt

If using a credentials file, be sure to format as follows, removing any line whitespace:

username=<WUSTL KEY ID>
password=<WUSTL KEY PASSWORD>
domain=ACCOUNTS.AD.WUSTL.EDU

Variable replacement

  • ${VOLUME_NAME} should be replaced with the name of your Storage Platform volumn.

  • <WUSTL KEY ID> should be replaced with your Wustl key ID.

  • <WUSTL KEY PASSWORD> should be replaced with the password associated with your Wustl key.

Using smbclient

Install samba-client

In the Debian family of operating systems (e.g. Debian, Ubuntu, etc.)

sudo apt-get update && sudo apt-get install -y samba-client

In the RedHat family of operating systems (e.g. RedHat, CentOS, etc.)

sudo yum install -y samba-client

Empty the default samba configuration

sudo truncate -s 0 /etc/samba/smb.conf

Record your credentials in a file with restricted permissions

cat > secret <<EOF
username=<WUSTL KEY ID>
password=<WUSTL KEY PASSWORD>
domain=ACCOUNTS.AD.WUSTL.EDU
EOF

chmod 0600 secret

Variable replacement

  • <WUSTL KEY ID> should be replaced with your Wustl key ID.

  • <WUSTL KEY PASSWORD> should be replaced with the password associated with your Wustl key.

Use smbclient to connect to storage with the SMB3 protocol to your storage volume.

smbclient -A secret -m SMB3 //storageN.ris.wustl.edu/${VOLUME_NAME} -c ls

Domain=[ACCOUNTS] OS=[] Server=[]

  ..                                  D        0  Wed Jan 31 12:40:03 2018

Or, to avoid recording credentials in a file:

smbclient -W ACCOUNTS -U <WUSTL KEY ID> -m SMB3 //storageN.ris.wustl.edu/${VOLUME_NAME} -c 'ls'

Variable replacement

  • ${VOLUME_NAME} should be replaced with the name of your Storage Platform volumn.

  • <WUSTL KEY ID> should be replaced with your Wustl key ID.

Enter ACCOUNTS\$USER password

Use smbclient to PUT data into storage

smbclient -A secret -m SMB3 //storageN.ris.wustl.edu/${VOLUME_NAME} -c 'cd Active; put somefile;'

Domain=[ACCOUNTS] OS=[] Server=[]
putting file somefile as \Active\somefile (69719.1 kb/s) (average 69719.1 kb/s)

Variable replacement

  • ${VOLUME_NAME} should be replaced with the name of your Storage Platform volumn.
