A look into Solaris, by Derek Crudgington

Firefox and RealPlayer

Monday, March 27th, 2006

To get RealPlayer working with Firefox just load the plugin. The directory SUNWrealplayer is in is /usr/lib/RealPlay

# cd /opt/local/firefox/plugins
# ln -s /usr/lib/RealPlay/mozilla/nphelix.so

while you’re at it, link the java plugin too if its not already there:

# ln -s /usr/j2se/jre/plugin/i386/ns610/libjavaplugin_oji.so

restart Firefox and verify everything went smoothly by going to about:plugins

Well the Solaris Boot Camp came to Dallas and it was a very cool thing, and Bob is a cool guy and was nice to meet. Anyone that can cram that much information into that small amount of time deserves some respect. Some things I learned from Bob (and some I forgot about):

FMA features like fmadm, fmstat

boot -m milestone=milestone allows you to boot to a specific milestone

boot -m milestone=all boots all milestones

boot -m milestone=none which is useful in reparing a system that have problems booting early

boot -m verbose will print a line of information at boot when every service is started

Change your default run level:
(To change to another run-level just skip the -d part)

svcadm milestone -d milestone/single-user:default

svc:/milestone/single-user:default is runlevel S

svc:/milestone/multi-user:default is runlevel 2

svc:/milestone/multi-user-server:default is runlevel 3

If you look at an FMRI entry:
svc://localhost/network/login:rlogin
notice the localhost part.. the word is eventually we’ll be able to use svc://someotherhost/network/login:rlogin

SMF service “unintialized” means that it didn’t start due to incomplete initialization (check sysidconfig, zlogin -C, NFS question)

SMF service “offline” means its tried to start but its dependencies weren’t met.

SMF service “disabled” means its off.

SMF service “maintenance” means error must be resolved by admin. check log.

SMF service “degraded” means its running at limited capacity in comparison to normal operation.

Cool presentation Bob, and let me know when the Sun Developers Day comes.

10 steps to install server

Wednesday, January 25th, 2006

This is the steps to setup a CD-less install server if you are using > Solaris 3/05 x86 (or a Solaris x86 with GRUB). They cleaned up a lot of things with GRUB booting off PXE and it is a lot easier and painless as this example shows. This does not include profiles so you will have to sit in through the install process and answer questions. It is just a quick and easy way to get Solaris x86 installed on a remote machine without burning CDs.

1. Download ISO images

2. Unzip them, run
lofiadm -a iso_file.iso
for each one

3. mkdir /mnt/disk1 /mnt/disk2 /mnt/disk3 /mnt/disk4

4. mount -F hsfs /dev/lofi/# /mnt/disk#
for each one

5.
/mnt/disk1/Solaris_11/Tools/setup_install_server /path/to/setup/installserver

6. For each CD:
/mnt/disk#/Solaris_11/Tools/add_to_install_server /path/to/setup/installserver

7.
/path/to/setup/installserver/Solaris_11/Tools/add_install_client -d -e client_mac -s install_server_ip:/path/to/setup/installserver i86pc

After this command it will give you information to use for the DHCP server you setup on step #10. If you are familiar with the old x86 network boot, you will notice they dont use SUNW.i86pc anymore and there is a lot less options to add for the DHCP server.

8. share -F nfs -o ro,anon=0 -d “Install Server” /path/to/setup/installserver

9. Run:
/usr/sadm/admin/bin/dhcpmgr
and follow the correct IP setup, defaults work great here if using 192.168 network.

10. Add Macro by clicking on Macros then Edit -> Create (Use the information from the add_install_client command to put in the DHCP Macro. It’s only 2 options: “BootSrvA” which is the IP address of the install server, and “BootFile” which is the name of the bootfile on the install server.

Tell your client to boot off using PXE!

BrandZ speed blowfish

Tuesday, December 20th, 2005

The openssl speed blowfish under BrandZ Linux beats the one under Opensolaris. I’m not sure what the deal with that is.

BrandZ Linux:

DTrace Example #2

Thursday, October 27th, 2005

Here’s another example where I use DTrace to fix a problem I was having:

The problem I was having is trying to upload something via FTP through a web application and it wasn’t uploading for some reason. The FTP daemon was receiving the commands but the file wasn’t showing up in the directory.

FTP log of the session trying to upload:

Oct 27 14:54:26 callacctweb ftpd[25157]: [ID 165209 daemon.info] USER pinnftp Oct 27 14:54:26 callacctweb ftpd[25157]: [ID 125383 daemon.info] PASS password Oct 27 14:54:26 callacctweb ftpd[25157]: [ID 201503 daemon.info] CWD / Oct 27 14:54:26 callacctweb ftpd[25157]: [ID 313182 daemon.info] PORT Oct 27 14:54:26 callacctweb ftpd[25157]: [ID 307055 daemon.info] TYPE Image Oct 27 14:54:26 callacctweb ftpd[25157]: [ID 206289 daemon.info] STOR logo-left.jpg

Nothing looks suspicious here, and even to test if it was a permission error I went ahead and made the directory +w by everyone. Still, I kept getting the same stuff, and no file showing up in the directory.

So I run opensnoop (as I tell the web app to upload the file):

What were looking for here is all of the ‘-1‘ FD values. This indicates there was an error somewhere. Looking at all of them, there’s only one that really sticks out, and its the name of the image I was trying to upload, logo-left.jpg

It has an error number of 13, lets see what this means:

root@callacct:~/DTraceToolkit-0.83# grep 13 /usr/include/sys/errno.h #define EACCES 13 /* Permission denied */ #define ECONNABORTED 130 /* Software caused connection abort */ #define ECONNRESET 131 /* Connection reset by peer */ #define ENOBUFS 132 /* No buffer space available */ #define EISCONN 133 /* Socket is already connected */ #define ENOTCONN 134 /* Socket is not connected */ /* XENIX has 135 - 142 */

It is showing I’m getting a permission denied. This makes more sense if you look at the FTP log it shows it issuing “CWD /” then trying to upload a file which means its changing to the root (/) directory first then uploading the file and failing with the permission denied. The root directory doesn’t have permission to let anyone upload there and the FTP web app shouldn’t be issuing a ‘cd /’ and then trying to upload the file.

If you haven’t checked out the OpenSolaris user group video footage you should now. I got this from benr. Some of it is hard to hear clearly but a lot of it you can understand and it talks about the OpenSolaris release and all mighty Newboot that will replace the Device Configuration Assistant.
