how to change network information of sun solaris systems

January 22nd, 2007

people new to networking under solaris seem to wonder how to change the ip-address or hostname of a machine regularly. so here you go, this is the list of files to change when updating your network information.

for ip changes edit the following files:

  • /etc/hosts
  • /etc/defaultrouter
  • /etc/netmasks
  • /etc/inet/ipnodes (if it contains the accordant entry for your hostname)

to change the hostname of a solaris system edit these files:

  • /etc/hosts
  • /etc/nodename
  • /etc/hostname.xyz (xyz stands for the corresponding network interface, such as bge0)
  • /etc/net/ticlts/hosts (obsolete in Solaris 10)
  • /etc/net/ticots/hosts (obsolete in Solaris 10)
  • /etc/net/ticotsord/hosts (obsolete in Solaris 10)
  • /etc/inet/ipnodes (if it contains the accordant entry for your old hostname)

you do not need to reboot your machine to apply this new information (this is unix, remember? ;)) - all you need is to restart the adequate service using the service management facility (smf):

svcadm restart svc:/milestone/network:default

out now: bigwheelers-exoticars.de

December 31st, 2006

december, the time for some just-for-fun-and-not-for-profit-projects. so some days ago we launched www.bigwheelers-exoticars.de. “we” is christian mueller, who did the flash-frontend, and myself. my job was the backend-coding, including gallery- and thumbnail-generation. all hail the gdlib! ;)

the site itself focusses on automobile tuning, mainly interior- and exterior-styling. frank and andreas do some crazy things for small money. if you want some new rims, especially 18″-20″ sizes, check it out as well.

solaris smf manifest collections

December 19th, 2006

short post again, just a quick note for you admins unwilling to stuck with init.d… ;)

there are a few repositories of solaris service management facility (smf) manifests on the net. jamesd maintains the repository on blastwave.org, which has grown quite well. the opensolaris guys have their own repository. last but not least thorleif has collected some links to various smf manifests as well.

sun ray 2 video specifications

November 30th, 2006

another reminder for me and for all who want to know which video specs the “new” sun ray 2 virtual display clients support:

  • sun ray 2: 1600×1200 max at 32bit
  • sun ray 2fs: 1900×1200 max at 32bit, supports dual monitor setups (so each screen supports 1900×1200 pixels)

and yes, you can still use your old vga monitors with the new sun ray thin clients. all you need is an dvi-to-vga adaptor (included in each sun ray 2 box).

and one rock!

November 28th, 2006

guys, this might be a bit off-topic from my other stuff in this blog, but i just have to say that and one rock sh*t! for all who don’t know who they are: and one is a german band playing a mix of synthpop and electronic body music (ebm). i attended their concert in magdeburg’s factory on saturday the 25th november of 2006: nearly three hours full of powerful rythms, a great voice (live quite as perfect as on the cd-recordings) and helluva fun. still today i am running around with a perfectly happy grin on my face… great stuff! smilie

chris maestro has some nice pictures of and one on stage, although none of the current tour can be found on flickr. i guess they will be published soon as the concerts pass by.

free solaris dvd for everyone!

November 23rd, 2006

sun gives away free dvds containing sun solaris 10 (6/06) and sun studio 11. it includes sparc and x86 versions. you better be quick as this is a time-limited offer. i like this because not all people have broadband to leech a full dvd image. decreasing the barriers for people to get in touch with solaris makes sense to me. personally i have no use for the media kit because i’ve just leeched solaris 10 x86 the week before.

so click this link to get your free copy of solaris 10!

tuning sun ray startup procedures

November 22nd, 2006

craig bender blogs on reducing sun ray server load by setting some simple values in the sun ray config. this results in faster startup times. here’s a quick abstract on what the sun ray engineering guys did:

  • Increase Authd worker threads from 8 to 32
  • Change utprodinfo to do an echo vs. a pkginfo
  • Use non-invasive methods for finding the Sun Ray MAC address or other information from the data store
  • Remove dtsession as a CAM application if not required
  • Increase the initial and max heap size for Authd

how to do this? read craigs entry on the think thin blog. after all this shows us that sun ray engineering is no black magic. :) i can’t wait to try this out….

hs_err decyphered… the followup

November 17th, 2006

i have to correct my statement of how to understand java’s hs_err error files: the tool posted on davids blog was not coded by him but was used sun internally before. it’s still an useful tool, i guess. ;) thanks for pointing out, dave!

microsoft cakes for everyone!

November 2nd, 2006

perhaps this should act as an update for my last post but i figured that this might be better placed in the fun-section. while one might think that microsoft is evil and blinkered, this photograph proves that there are sane people in redmond as well:

cake from microsoft for the firefox team at mozilla

the guys at mozilla got this one while shipping the final release of firefox 2.0. great stuff and a noble sign of the internet explorer team. perhaps i should code a competitor application to microsoft exchange to get a cake as well? shouldn’t be that hard. ;)

firefox 2.0 for solaris is out

November 2nd, 2006

mozilla firefox 2.0 - upgrade now!hey folks! sorry to say, i’ve been to busy to blog for the last week. so this might come a bit late, as this news is already some days old (woah, this is decades in internet time!): the official release of firefox 2.0 is available for solaris. you can find the pre-compiled packages for solaris sparc and x86 at releases.mozilla.org. the nice folks around masaki katakai provided this one again. katakai san has also blogged on how to set up a multi-user and multi-language environment for firefox on solaris. now go out and equip your solaris desktops with the brand-new firefox!

by the way there are many ways you can get involved in the development of this fine piece of code poetry. for instance i file bugs on a regular basis. ;)
