3d printing software and solidoodle?
by Tom Horsley 02 Sep '13

02 Sep '13

Now that Fedora has lots of 3d printing related software in the repos and my Solidoodle 2 printer is arriving this week, I just thought I'd ask if anyone has used any of the fedora supplied versions of the software with a solidoodle? I'll be giving it a try, but wondered if anyone else already has experience and advice tweaking things for the solidoodle.

Yum: a suggestion
by Timothy Murphy 02 Sep '13

Yum only tells me the sites it has _failed_ to download from. Wouldn't it be nice if it also told us which sites _succeed_? I'd like to know who to be grateful to. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Trouble setting up kickstart
by Michael Larsen 02 Sep '13

02 Sep '13

I'm trying to set up a kickstart server on my home network. I can't get network booting working. DHCPD and tftp are working, but the tftp request on the client is timing out with: PXE-E32 TFTP open timeout I've googled the heck out of this issue and can't find a fix. I was hoping someone here could help me out. My dhcpd.conf file: # # DHCP Server Configuration file. # see /usr/share/doc/dhcp*/dhcpd.conf.example # see dhcpd.conf(5) man page # option space pxelinux; option pxelinux.magic code 208 = string; option pxelinux.configfile code 209 = text; option pxelinux.pathprefix code 210 = text; option pxelinux.reboottime code 211 = unsigned integer 32; allow booting; allow bootp; class "pxeclients" { match if substring (option vendor-class-identifier, 0, 9) = "PXEClient"; next-server 192.168.10.90; filename "pxelinux.0"; } subnet 192.168.10.0 netmask 255.255.255.0 { option domain-name "larsenhaus.org"; option domain-search "larsenhaus.org"; option domain-name-servers 192.168.10.60,192.168.10.90; option routers 192.168.10.10; range dynamic-bootp 192.168.10.100 192.168.10.200; default-lease-time 3600; max-lease-time 4800; } My xinetd tftp file: # default: off # description: The tftp server serves files using the trivial file transfer \ # protocol.

During my research I saw a post somewhere that talked about tftp having issues with some RealTek network cards. The kickstart server is running a controller with the RTL8101E/RTL8102E chipset. The poster said he fixed his problem by setting the tftp block size explicitly to 512, but I've been unable to determine how to do so. Are there any obvious errors in my configuration? If not, can anyone advise how to set the tftp block size? Thanks in advance. James

grep by paragraph
by Timothy Murphy 02 Sep '13

02 Sep '13

Is there an option for grep, or some similar program, that will print out a whole paragraph - defined as the section between two blank lines - containing a given word or phrase? Such as the above 4 lines. If not, can anyone suggest a simple script that will do this? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland
