  • Easy packet captures straight from the Cisco ASA firewall … – Takeaway: Lori Hyde tells you how to capture packets directly from the Cisco ASA without using a separate packet-sniffing utility, first by setting up an ACL to define the traffic and then using the capture command.

  • Home – Prepaid Wireless Internet Access – The frequent and occasional traveler requiring access to the Internet knows the problem: You are there, your notebook is there but no Wifi hotspot. But don't despair. 2G and 3G cellular operators in some countries offer wireless Internet access using GPRS/EDGE/UMTS via prepaid SIM cards. <br />
    For outsiders, it's a bit difficult to find out if such an offer is available at the destination. This Wiki aims to help finding such offers. The search the Wiki for a particular country, enter its name in the search dialog box on the left. In case you travel to countries for which you can't find a local offer, take a look at Vodafone WebSessions, which can be used to access the Internet in most European countries and also some countries elsewhere with a prepaid card for a daily fee.<br />

  • Booting once-only – GNU GRUB Manual 0.97 – You can teach GRUB to boot an entry only at next boot time. Suppose that your have an old kernel old_kernel and a new kernel new_kernel. You know that old_kernel can boot your system correctly, and you want to test new_kernel.<br />
    To ensure that your system will go back to the old kernel even if the new kernel fails (e.g. it panics), you can specify that GRUB should try the new kernel only once and boot the old kernel after that.<br />

  • Rotating Log Files – O’Reilly Media – Log files grow. That's what they're there for, after all. As a systems administrator, you need to be able to control log growth. FreeBSD provides a basic log file handler, newsyslog. The newsyslog program handles standard log file rotation. The oldest logs are deleted. Each old log is renamed. Finally, the current log is moved and a new log file is created. The newsyslog program can also compress files, restart daemons, and in general handle all the routine tasks of shuffling files[…]
