Main disadvantages are lack of correctness, reliability and security where the OpenDNS/etc score high. However, the privacy aspects of Google DNS is another can of worms. I tend to disagree here. You are assuming that OpenDNS / Google DNS is always reliable, correct and secure(???). If you dont trust your ISP to provide the basic service that he is expected to provide reliably, there is something wrong.

There will always be people finding intelligent ways to work around this. Figure out what you are achieving by blocking and see if there is a need for you to do it.

I feel this defeats the very purpose of a passphrase!! A person getting hold of the ssh-agent config (or whatever file that holds the passphrase) file can just as easily access the servers!! For this reason, ssh-agent will never save the passphrase in a config file. You are forced to enter it manually whenever you start ssh-agent and add keys. Once the keys are added, you can then use ssh repeatedly without passwords. The main security problem with ssh-agent is that it creates a unix domain socket for communication with ssh. This file/socket is secured using standard unix file permissions and hence root can access the ssh keys for any local user. Suggest you read this article for a good understanding of ssh/ssh-agent interaction: http://unixwiz.net/techtips/ssh-agent-forwarding.html True, ssh-agent only avoids the need to type passphrases recently. Also, If you want you can add a lifetime for the identify it holds. ssh-agent runs as a user process and it does not store the passwords. For the point about root having access, if you dont trust your admin or if your admin is not trust worthy, you are doomed. It is not about just reading the sockets, what if he replaces the ssh binary so that he gets a copy of the password when you type it et al. -balaji -- http://balajin.net/blog http://flic.kr/balajijegan ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

I get a download speed of more than 50 KBps. Changing in /etc/resolv.conf is a temporary fix, i guess. Most routers have the option to configure the DNS IP's. Doing it there is a permanent solution.

Any hosted DNS service has exactly the same problem. True, but the assumption is that the ISP has some clue not to use a DNS server half way across the globe. Perhaps the best option is to run bind as a caching name server for local users. IIRC, the default config of every distro is to run bind as a pure cache only name server. I am not sure. I run a ubuntu box and it does not have bind installed by default. However, OpenDNS/GoogleDNS/etc have some neat technology deployed through UDP Anycast. Good reading for any networking enthusiast.
