System info in solaris and linux

If you work for a non microsoft shop, its highly likely that you would develop and/or deploy your applications in linux or solaris systems. Our windows to the target system is the ubiquitous command line via ssh. Here are some of the commands that I find useful to get the details of target system.

Solaris commands

Hardware deatails

Processor /usr/sbin/psrinfo -v

Memory /usr/sbin/prtconf -v | grep Memory

HD /usr/sbin/format < /dev/null

Current statistics

memory statistics /usr/bin/vmstat

io statistics /usr/bin/iostat

network statistics /usr/bin/netstat

disk space usage /usr/sbin/df

Process details

list of processes running /usr/bin/ps -aef

memory usage for a given process /usr/bin/pmap processid | grep total

list of ports open for a given process

/usr/proc/bin/pfiles processId | grep "port: portId"

I have listed only the commands. A simple google or map page should give you details about each of the command. I will follow it up with Linux command later.

Ubuntu on T43.

I have been using Linux for number for years starting with slackware and moving on to Redhat for a while landing on Debian and its derivative ubuntu.

I have always used Linux on desktops and servers. Its time to use it on my laptops too. I decided to install ubuntu edgy eft ( that's version 6.10 if you are not keeping track of the codename for the releases ) on my T43 couple of days ago. To my pleasant surprise, everything worked out of the box. Well almost everything.

It recognized native resolution of 1400x1050. All the function keys, volume buttons, trackpoint, WiFi card, sound card were recognized out of the box.

ThinkWiki is good resource for all your linux compatibility questions.

I still have to get my Fingerprint Reader and Hard disk's Active Protection System running. Except for APS, I am not very keen on getting Finger Print Reader working.

Overall it look me less than 20 minutes to install Linux on Thinkpad. Thats less than the time I spent configuring Windows XP Profession when I bought my laptop.

So if you are like me, waiting for the right time to install linux on your laptops, thanks to Ubuntu, now is the time.

I am not going to review Ubuntu 6.10 here. Every linux site worth its salt has detailed review along with installation procedure. The only note I would like to add is that you can download Eclipse 3.2 via apt. I am still a emacs guy but its good to know that you are just "sudo apt-get install eclipse" away
