sendmail – Warning: RunAsUser for MSP ignored, check group ids

Every time that I sent an email with an user, the system was displaying the message that could not chdir to the mail directory. I solved following the steps below:

user@linux:~ $ mail blackhole@domain.com
Subject: Test
Sending email to test
.
Cc:
user@linux:~ $ WARNING: RunAsUser for MSP ignored, check group ids (egid=503, want=51)
can not chdir(/var/spool/clientmqueue/): Permission denied
Program mode requires special privileges, e.g., root or TrustedUser.

The group ID 503 was from the user that was logged in and sending the mail. The problem in this system was that it needed setgid set in the sendmail binary file.

root@linux:~ # ls -l /usr/sbin/sendmail.sendmail
-rwxrwxrwx  1 root smmsp 757168 Apr 15  2008 /usr/sbin/sendmail.sendmail

root@anotherlinuxhost:~ # ls -l /usr/sbin/sendmail.sendmail
-rwxr-sr-x  1 root smmsp 757168 Apr 15  2008 /usr/sbin/sendmail.sendmail

root@linux:~ # chmod 2755 /usr/sbin/sendmail.sendmail
root@linux:~ # ls -l /usr/sbin/sendmail.sendmail
-rwxr-sr-x  1 root smmsp 757168 Apr 15  2008 /usr/sbin/sendmail.sendmail

Restarted sendmail and no error message is shown when sending a message.

SteelSeries Siberia USB Soundcard on Windows 7

I bought a SteelSeries 5Hv2 USB on ProGaming Computer. It’s a nice headset and comes with a USB soundcard similar to the SteelSeries Siberia USB soundcard.

According to the website, it had drivers for Windows XP and Windows Vista but no  support for Windows 7. I solved this problem by installing a beta driver available at the SteelSeries blog. Other people reported success right-clicking the driver installer and selecting to execute in Windows Vista combatibility mode.

Now you just need to download the official Windows 7 drivers at the manufacturer’s website.

Sun System Management Services – Error: Exclusive session is in use, disconnecting.

You need to connect to a System Controller (SC) to manage a domain in a Sun Fire E12K, E15K, E20K or E25K. It has the System Management Services (SMS) software that allows you to control the domains.

To view the console, you use /opt/SUNWSMS/bin/console -d <domain letter or domain name> but I was having the error message “Exclusive session is in use, disconnecting”.

sms-svc@sc0:/ $ console -d domain06
Trying to connect…
Connected to Domain Server.

Exclusive session is in use, disconnecting.

I asked to a friend why I was having this problem and he said that I needed to kill the other session.

sms-svc@sc0:/ $ w
9:24am  up 76 day(s),  3:53,  2 users,  load average: 0.91, 2.04, 1.52
User     tty           login@  idle   JCPU   PCPU  what
root     pts/1         9:08am     9                console -d domain06
root     pts/2         9:19am                      w

I found out which PID is running the console, then killed it.

sms-svc@sc0:/ $ ps -ef | grep consol
root  3127     1  0   Sep 19 console  0:00 /usr/lib/saf/ttymon -g -h -p sc0-01-vix console login:  -T sun -d /dev/console
sms-svc 11229 11182  0 09:24:18 pts/2    0:00 grep consol
sms-svc  5492 5398  0 09:09:23 pts/1    0:00 console -d domain06

sms-svc@sc0:/ $ kill 5492

Worked as expected:

sms-svc@sc0:/ $ /opt/SUNWSMS/bin/console -d domain06
Trying to connect…
Connected to Domain Server.
Your console is in exclusive mode now.
