Solaris dump analysis

I had to debug a solaris crash dump and had no ides. Google search wasn’t much useful until finally I found this article:

have a look at this article, this suggests how to debug the core and find the offending process and root cause of the core in case of kernel panic.

install all solaris software from http

If you are behind a firewall and install some software like top or wget then you can not use sunfreeware, and why because ftp is blocked. Now that is not the case any more, you can go the http mirror site of sunfreeware and here is the link for the same

http://ftp.sunfreeware.com/ftp/pub/freeware/i386/5.10/

Note: you just need to change the words in bold for sparc or i386 and version of the solaris.

[Solution] Solaris issue with wget not resolving Domain name (DNS name lookup failure)

Today I was working with Solaris and after I had set up the NIS+, DNS server, IP Address and completing the basic setting. I was using the pkg-get util from the freesunware.com

The utility was using wget and it was failing constantly. From the looks of it, it was very clear that the wget utility was unable to find the IP address from the name. Name resolution was not happening, while dig and nslookup was able to do the DNS lookup.

After searching for quite sometime all that I could see was, in one of the forums, \”Did you have NIS enabled?\”

That seemed interesting and thus I got the direction to look for where I can find the solution. And finally I found that in \”nsswitch.conf\” there were settings to find how the various lookups should happen.

For the host entry, I saw that after looking at the nis the lookup would end so I changed the sequence to look at \”files dns\” also and then quit. And it worked. Hope it helps you too 🙂
