ping command expansion
by Chuck Noyes 05 Apr '07

05 Apr '07

Hi All, I want to ping lots and lots of consecutive ip addresses. If I issue ping 192.168.1.{1,2,3}, I get ping 192.168.1.1 192.168.1.2 192.168.1.3 which isn't exactly what I want. How can I issue a "short-hand" ping command, that will expand to ping 192.168.1.1 ping 192.168.1.2 ping 192.168.1.3 etc. TIA, -- -Chuck

Consulting project - Linux J2ME Architect and developer
by John Spencer 04 Apr '07

04 Apr '07

My client in MA has the following needs for Linux J2ME consultant(s). This could be one position if the developer can do the architecture as well. Otherwise they will need and architect as well as a developer. If you are qualified and interested, please give me a call or send me an email. 1. Architect key changes to their thin client which is Linux 2.6 based which is being moved over to a mobile device. The key is architecture. Strong documentation, strong embedded Linux (ideally 2.6). Estimated about 3 weeks to do the architecture. 2. Development role will include constructing the framework, defining the API, implementing lower layer (abstraction) interfaces from sockets to application stacks like SIP/RTP, etc. strong C and Linux. Mobile Embedded Linux architect required to perform high level analysis and design work for a project that involves porting an existing thick client to a Linux/Java environment for the mobile industry. Consultant's responsibilities will include: - taking the recommendations from the customer - quickly learning the existing client architecture - identifying and developing the best approach to porting the client - delivering a complete design and porting guide using best practices - remaining available for ad-hoc consultation throughout the stages of the port Successful consultant must have solid experience in embedded Linux, strong knowledge of Java ME(J2ME), experience in designing clients for such environments, and the proven ability to lead a team in the initial design phases of a project. Estimated about 3 mths to do this piece of the project. The development team exists and is ready to begin the porting effort, but needs strong guidance from an experienced, senior architect. Must be able to start soon.

vpn solution
by Michael Long 03 Apr '07

03 Apr '07

I now have a need to setup a vpn to my office network and I have just enough admin skills to be dangerous. I am running opensuse 10.2. Am I better off installing openswan (or some other vpn solution) or purchasing an appliance with a vpn built into it. My main concerns are ease of use and security. I am currently using a linksys router as my firewall and gateway to the internet. Each of my computers inside the network also have there own firewalls. Thanks, Mike

do you just need remote access (shell / email) or do you need a bunch of stuff? while I don't have much expirience w/vpns, tunnelling via ssh handles what I do very well. Add securing it via pub/priv keys and its set. -Eric -----Original Message----- From: Michael Long <mlong(a)datalong.com> Subj: [Wlug] vpn solution Date: Tue Apr 3, 2007 7:21 am Size: 601 bytes To: WLUG <wlug(a)mail.wlug.org> I now have a need to setup a vpn to my office network and I have just enough admin skills to be dangerous.

I wouldn't expect this for a HID device, but since the event* nodes aren't showing anything, who knows... In the kernel, it would be interesting to see what happens if you turn on DEBUG in hid-input.c, which currently contains, #undef DEBUG ... static void hidinput_configure_usage() ... goto ignore; // lots of these gotos! -jamieg ... ignore: #ifdef DEBUG printk("IGNORED\n"); #endif -Jamie

At this point I'd start putting printk's and turning on DEBUGs in the kernel source. For starters, drivers/usb/input/hid-core.c:hid_input_report() drivers/usb/input/hid-input.c:hidinput_configure_usage() I typically do something like this, $ make $ make modules_install INSTALL_MOD_PATH=$(pwd)/tmp (don't go installing under /lib just yet) $ rmmod foo $ insmod ./tmp/..../foo.ko [ unplug, replug, dmesg, tail messages, rinse, repeat ] -Jamie
