Tether Huawei U7519 Wind Mobile Linux

The following steps will enable the use of your Wind Mobile Huawei U7519 as a 3G modem.

Recently I bought  a Huawei U7519 phone on the Wind Mobile service. The phone tethers using Windows but what use is that to me?  Here is how I made it work using Linux.

As root:


echo "option"  >> /etc/modules

edit /etc/rc.local and add before exit 0: echo '12d1 101e' > /sys/bus/usb-serial/drivers/option1/new_id 


Download and install the software as per the instructions at this link:


You should be able to plugin your device and will have a /dev/ttyUSB0 (which you can confirm with ls /dev/ttyU*

Now you can right click your NetworkManager in the panel and edit connections > mobile broadband > add t-mobile internet then edit that profile like so: mobile broadband > apn =

also edit PPP  and deselect allow bsd ..  and deselect allow  deflate


You can also select connect automatically on the mobile broadband tab.

Surfs up!

SXCE to OpenSolaris Migration on Sparc

Using some already existing blogs/mail-lists and elbow grease, I've migrated a SPARC server to OpenSolaris from SXCE.

With SXCE EOL coming up fast and the AI not quite up to speed (for this instance at any rate), I've cobbled together and carried out a migration of a Sun e220r sparc box from SXCE.

I used quite abit from Edward Pilatowicz's blog and also Alex Eremin's blog . I altered/diverged to suit my needs as well due to things changing rapidly in OpenSolaris.

I built IPS from the gate, more details on IPS and the mercurial url here: . With that installed proceeded to create an new root pool on a separate disk.

I utilized the following from Edward's blog, where I've diverged/changed I have commented out the original and noted beside my change:

# we're going to do our install in /a

# mount our zpool on /a
mkdir -p $PKG_IMAGE
mount -F zfs rpool/ROOT/opensolaris $PKG_IMAGE
mkdir -p $PKG_IMAGE/opt
mount -F zfs rpool/ROOT/opensolaris/opt $PKG_IMAGE/opt

# create the basic opensolaris install image.
#pkg image-create -F -a $PKG_IMAGE
pkg image-create -f -F -a $PKG_IMAGE # Sparc requires the dev repos
#pkg refresh
pkg -R $PKG_IMAGE refresh --full # We're not clobbering our original or changing it so the next few are mine too
pkg -R $PKG_IMAGE install entire
pkg -R $PKG_IMAGE install SUNWcsd SUNWcs
pkg -R $PKG_IMAGE install babel_install

# seed the initial smf repository
cp $PKG_IMAGE/lib/svc/seed/global.db $PKG_IMAGE/etc/svc/repository.db
chmod 0600 $PKG_IMAGE/etc/svc/repository.db
chown root:sys $PKG_IMAGE/etc/svc/repository.db

# setup smf profiles
ln -s ns_files.xml $PKG_IMAGE/var/svc/profile/name_service.xml
ln -s generic_limited_net.xml $PKG_IMAGE/var/svc/profile/generic.xml
ln -s inetd_generic.xml $PKG_IMAGE/var/svc/profile/inetd_services.xml
ln -s platform_none.xml $PKG_IMAGE/var/svc/profile/platform.xml


After that I finished with:

echo "rpool/ROOT/opensolaris  -  /  zfs  -  no  -" >> $PKG_IMAGE/etc/vfstab

echo "rpool/ROOT/opensolaris/opt  -  /opt  zfs  -  yes  -" >> $PKG_IMAGE/etc/vfstab

devfsadm -r $PKG_IMAGE

bootadm update-archive -R $PKG_IMAGE

installboot -F zfs /platform/$(uname -i)/lib/fs/zfs/bootblk /dev/rdsk/c0t0d0s0


 Copying relevant networking, passwd, ssh keys, etc. files from the running SXCE system to $PKG_IMAGE, I successfully booted to my OpenSolaris install and tweaked from there.

OpenSolaris Virtualbox Guest and NFS

Quick notes regarding nfs mounting from an OpenSolaris VBox guest.

I came up against an issue mounting via nfs from a Linux host to an OpenSolaris virtualbox guest (see this post for automounting nfs on OpenSolaris). Checking the host's logs revealed the issue: mountd:  [...] refused mount request [..] illegal port.

This is seemingly caused due to the natted connection between guest and host. Adding (insecure) in the host's /etc/exports line for this export enabled the guest to successfully mount the nfs share.
