comment Secure copy uucp style
As Ярослав Рахматуллин (hope the russian charset isn't messed up) pointed out correctly in his answer below, messing around with self-replicating shellscripts is messy. Your answer is useful and also pretty beautiful at the same time - I don't know why I didn't think of that first. I think I'll just use exactly that what you gave and wrap it up so that I can use my beloved uucp hashpath style. :-)

comment Secure copy uucp style
Oh, I know about that - that works perfectly. It starts getting interesting if you need to cross more than one hop. Usually it goes like this: localhost->my_corp_jumphost->vpn->customer_jumphost->cluster_head_node->clustern‌​ode . Quite a few hops and messing around with tunnels starts getting really nasty after a while. Actually I have a similar setup in my localhost's ssh_config file, "RemoteForward 3128 127.0.0.1:3128, ForwardAgent yes, LocalForward 2222:jumphost:22" and a few others.

comment Lots of hits from 173.252.103.3
What is being hit, what is that 400, how did you observe that, do you have logfiles etc. If you expect a helpful answer you must give more information. If you see this in your IIS logfiles, then what referrer is being given for instance? Maybe someone just shared a link pointing to your website.

comment VirtualBox inbound network connections failing
Sorry, no, I can't. It's just an observation I made myself. Because of this annoying fact I always set up two virtual interfaces for the VM guests, one NATed for Internet access, and one host only network for communication with the host and other VMs. I never found out why it doesn't work, maybe this is an combination of OSX version and MPB model. But you know what? I just got a brand new (used) Macbook and I haven't tried if it's working now. Will do later this afternoon...

Do you try to bridge up en1, the WiFi adpaptor? That doesn't work. Try en0, the regular Ethernet port.

comment VLAN trunking between Juniper EX -> Cisco Catalyst -> and Cisco Router
It doesn't make sense. So, the host WAS conntected to Catalyst/#46, and now... it's connected to ge-0/0/6 on EX or what? Please improve your question.

comment What packages do I need to install to serve php pages from apache2 on Fedora 17?
@CristianCiupitu No, this is about AWS instances and how to deploy them with a set of software reproducibly.

comment Is it possible to migrate OS X Server user passwords to Linux?
Oh, they store it in a regular SHA-512 format. But anyways, that's not necessarily compatible to what Linux is using - md5 or sha-1, at it's best. Since I don't know if you can set the Linux-shadows to SHA-512 I didn't bother to answer this question. It's out of my expertise...

comment What packages do I need to install to serve php pages from apache2 on Fedora 17?
I think the OP wants to know how to install the necessary packages via the user-data from AWS. To be honest, I invested an hour of research into it: I did this before with Ubuntu just to learn that it doesn't work like that with Fedora. They have their own funky way of dealing with user-data, and until now I didn't grok how the utilize /etc/cloud. The documentation is, midly said, crap. At this moment I'm talking to the Fedora-cloud people and I hope I'll be getting some insight... I'm really curious myself.

comment My VPS apache goes down often
So a connection timeout? Did you try tcpdump on the server? Do you actually see the requests? Does the TCP-handshake work out well?

comment Open ports broken from internal network
Would you please show us the FORWARD chain from the filter table? tcp/12345 still has to be allowed there and since you get a connection reused, you might be hitting a REJECT rule there. Edit: Just noticed, this posting is kinda... old. Feel free to answer if you are sill having the problem (I hope you sorted this out by now;)

comment IPv6 DNS Lookup
Refer to RFC 4472, section '5.2 DNS Lookups May Query IPv6 Records Prematurely' - it's a very common problem with IPv4 single stack hosts.

comment Iptables rules make communication so slow
Did you try a tcpdump yet to check in which phase of the connection it's getting slow? Also, what might be the case - wildy guessing here - is that the machine from which you want to connect to the server doesn't have a proper reverse lookup in DNS. So if the application you want to connect to tries so get the hostname of that IP-address, it'll wait for an answer from DNS (regulary hacing this problem at a customer on machines which don't have proper DNS or unpopluated /etc/hosts)

comment Can't get port forwarding to work on Ubuntu
@Znarkus Try a iptables -t nat -A OUTPUT -p tcp --sport 3478 -s 10.0.0.7 -o eth0 -j MASQUERADE - this enables SNAT for this very one IP-address.
