ubuntu JE ? slightly off topic
A co-worker just informed me that there is now a ubuntu ce (christian edition) and while I haven't had the time to take a look, I thought it might be nice to have a je.

OT: Israeli web host ratings?
I am about to open an account with an Israeli web hosting company but before I do that I wanted to know if anyone knows of a site that can show me how that host has been doing, like a rating site where I can see what complaints people may have (or compliments) about a particular host. Does anything like this exists in Israel (or for Israeli hosts)?

Then use iptables -nvL to get the count of packets and bytes that passed through this rule.OK, so I took Nadav's advise which turned out to be pretty simple:1. addgroup skype and chown skype /usr/bin/skype; chmod g+s skype /usr/bin/skype in order to run skype in its own group. That way I hope to: a. avoid multi-cpu troubles (though my current system is single-core) b. speed things up by having to match gid's instead of command names.2. setup iptables rules to the effect of:# match all outgoing packets from gid skype and mark their connection iptables -A OUTPUT -m owner --gid-owner skype --out-interface eth0 --protocol tcp -j CONNMARK --set-mark 1iptables -A OUTPUT -m owner --gid-owner skype --out-interface eth0 --protocol udp -j CONNMARK --set-mark 2 # all packets which match the connection should go through the skype ruleiptables -A OUTPUT -m connmark --mark 1 -m comment --comment skype-out-tcpiptables -A OUTPUT -m connmark --mark 2 -m comment --comment skype-out-udp # match all packets on Skype's public TCP port and mark their connectioniptables -A INPUT -p tcp -m tcp --dport 31673 --in-interface eth0 -j CONNMARK --set-mark 1iptables -A INPUT -p udp -m udp --dport 31673 --in-interface eth0 -j CONNMARK --set-mark 2 # all packets which match the connection will be counted by theseiptables -A INPUT -m connmark --mark 1 -m comment --comment skype-in-tcpiptables -A INPUT -m connmark --mark 2 -m comment --comment skype-in-udp This allows me to distinguish in vs. out traffic and tcp vs. udp traffic. A simple perl script that uses IPTables::IPv4 perl module (i.e. direct access to the syscalls) and looks up at the comments gives me all 8 numbers (tcp/udp, in/out and packets/bytes). I'll provide the scripts if anyone is interested. If you see an error in what I did then I'd appreciate a howler.I'm now trying to find a way to identify the Port Unreachable ICMP packets which I see to be sent back to Skype's UDP port (and are currently dropped together with other ICMP packets). Current plan is to use the u32 extension. If someone knows how to achieve that (the ICMP packet recognition, either using u32 or whatever) I'd appreciate a pointer. And double-thanks to Nadav for pointing me to read the iptables manual more carefully - I found the geoip module mentioned there very promising.Cheers,--Amos-- Military justice is to justice what military music is to music

Re: Red Hat SysAdmin Course
Hi Michael,
By nature, this list is a place where very few if any people take these
types of courses. In fact, most of the list members are qualified to
deliver these course themselves. So I think that your question might be
better sent to one of the Hebrew Linux lists that have a wider readership
and will be more likely to have participants who can answer your question.

Re: Red Hat SysAdmin Course
On the other hand, because this list includes many who are qualified to
deliver these course, you might get some pointers as to what to look for and
what to avoid.
I teach such a course, and my recommendation is to make sure there is plenty
of hands-on time. Ideally, every student should have a computer in front of
them where they can try out the concepts as they are taught, and ask questions
right away, in addition to lab time where more complex exercises are carried
out. This computer should be one on which you can try anything without fear of
breaking the installation (i.e. don't use your own laptop!) and of course it
should be the same system being taught.
I find networking concepts are very important, and I like to set up servers on
my computer and invite the students to access mine (samba, ssh, apache, cvs,
etc.). Then they learn how to set up their own and visit each other. By
learning how to set up and debug servers, a lot of other concepts are
practiced.
I also find the boot process an important topic. Knowing what is started when
is important when debugging systems.
I consider building the kernel a pretty fundamental exercise. I schedule this
before a break or at the end of the day so that we don't waste time waiting
for it to compile. If students take the laptops home, I encourage them to
experiment with removing items from the configuruation until the kernel stops
working, then trying to figure out what broke and why. (I sure learned a lot
this way)
