Qualcom GOBI 2000 UMTS/GPS 3G modem with Gentoo (ThinkPad W510)

Wednesday, 27 April 2011 18:52

I'll just shortly summarize my steps (15 overall) to get the Qualcom GOBI 2000 UMTS/3G/GPS modem in my Lenovo Thinkpad W510 up and running.

Stock 2.6.38.4 Kernel with CONFIG_USB_SERIAL_WWAN=m, CONFIG_USB_SERIAL_QCAUX=m, CONFIG_USB_SERIAL_QUALCOMM=m, CONFIG_PPP=y, CONFIG_PPP_MULTILINK=y, CONFIG_PPP_FILTER=y, CONFIG_PPP_ASYNC=y, CONFIG_PPP_SYNC_TTY=y, CONFIG_PPP_DEFLATE=y, CONFIG_PPP_BSDCOMP=y, CONFIG_PPP_MPPE=y, CONFIG_PPPOE=y
(modules will be called usb_wwan, qcaux, qcserial)
Add "usb_wwan" to /etc/conf.d/modules
# modprobe qcserial
(or reboot)
USE-flags for net-dialup/ppp: activefilter, dhcp, eap-tls,gtk, pam, -atm, -ipv6, -mppe-mppc, -radius
# emerge -av net-wireless/gobi_loader net-dialup/ppp
Snag the firmware files from a windows installation (/mnt/win/Program\ Files\ \(x86\)/QUALCOMM/Images/Lenovo/) and copy them to "/lib/firmware/gobi/"
(I just copied all files and indicated the origin in the file name with the originating Dir a MD5SUM and the provider they are intended for. See list below - klick "Read more...")
Link the desired firmware files to UQCN.mbn, amss.mbn and apps.mbn (gobi_loader will only load exactly these file names)

Debian EXIM4 smarthost

These are the steps to get a flawless working SMARTHOST on Debian Lenny 5.04. All you need to do is to run the exim4-conf and add some lines to /etc/exim4/passwd.client. You do not even need to touch the template file. In this setup Exim will deliver mail to the local inbox, if it finds a .forward file in ~ exim will deliver the mail to the address provided in the .forward file. Read more... Add new comment

KVM host settings

Sunday, 06 December 2009 22:14
Some things i came across when I was setting up a new Linux KVM host: Which scheduler on the host ist the one to go for? I was playing around with the available schedulers but thankfully someone else did that before. See Bugreport #505695 on the RedHat Bugzilla. So apparently the best suited scheduler for a KVM host is the "deadline" scheduler. Which scheduler on the VM ist the on to go for? In the "Redhat Oracle 10G best practices document" (PDF) they suggest the "noop" scheduler. It states, that with the "noop" scheduler, the host is able to optimize the I/O request, which is what we want. Read more... Add new comment
