In this example a squid installation will use RADIUS “squid_radius_auth” Squid RADIUS authentication helper to authenticate users. Get last version of squid radius auth helper at: http://www.squid-cache.org/contrib/squid_radius_auth/ Download: [leo@srv01 leo]# wget http://www.squid-cache.org/contrib/squid_radius_auth/squid_radius_auth-1.10.tar.gz Extract: [leo@srv01 leo]# tar -xvf squid_radius_auth-1.10.tar.gz Go to directory: [leo@srv01 leo]# cd squid_radius_auth-1.10 Compile: [leo@srv01 squid_radius_auth-1.10]# make gcc -O2 -Wall -g -c -o squid_rad_auth.o squid_rad_auth.c gcc -O2 -Wall -g -c md5.c gcc -O2 -Wall -g -c util.c gcc -g -o squid_radius_auth squid_rad_auth.o md5.o util.o Now the installation, for my needs, I wanna keep binary into /usr/lib/squid/ and configuration file into /etc/squid/ and I don’t wanna take man files then edit Make.inc like this: ...

The command to reset the system time to 18-APR-2010 09:47 is: $ SET TIME=18-APR-2010:09:47 Note the colon between the date and the time specification. (This extra colon is a requirement resulting from the DCL parsing rules. Normally, there is a space between the date and time.) On OpenVMS VAX, once a year between January 1st and circa April 11th, or whenever a different SYS.EXE system image is bootstrapped, issue the command: ...

This entry will cover how to send nagios alerts to twitter, in the examples to follow using curl. Firstly edit commands.cfg And add the two following line: define command { command_name notify-by-twitter command_line /usr/bin/curl --basic --user "twitteruser:twitterpassword" --data-ascii "status=[Nagios] $NOTIFICATIONTYPE$ $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$" http://twitter.com/statuses/update.json } define command { command_name host-notify-by-twitter command_line /usr/bin/curl --basic --user "twitteruser:twitterpassword" --data-ascii "status=[Nagios] $HOSTSTATE$ alert for $HOSTNAME$" http://twitter.com/statuses/update.json } Now define a contact for this twitter service into: contacts.cfg ...

DCL implements command line editing and recall, so that users can more easily correct typing errors and reuse previous command lines. Recall buffer: access to recently issued commands $ RECALL string Bring up last command beginning with string. $ RECALL/ALL Displays all commands and their numbers. $ RECALL number Use a number found in RECALL/ALL. Command line editing (if it isn’t on, do: $ SET TERM/LINE): $ {up-arrow} Previous command in recall buffer. $ {down-arrow} Next command in recall buffer. $ {Ctrl A} Toggle insert/overstrike editing. $ {Ctrl D} Move one character left. $ {Ctrl E} Move to the end of the line. $ {Ctrl F} Move one character right. $ {Ctrl H} Move to the beginning of the line. $ {Ctrl J} Delete word left of cursor. $ {Ctrl R} Rewrite the command line. $ {Ctrl U} Delete line left of cursor. $ {Ctrl X} Cancel the current command line. Miscellaneous: ...

I installed Solaris 10 05/09 on a machine and I used whatever the default swap space setting when I built the box. Now I need to increase the swap space and I can’t add a swap file, like was possible under UFS. If your swap device is in use, then you might not be able to delete it. Check to see if the swap area is in use. For example: ...
