Seth, I've seen that Z-Push 2.0.6 now supports HTML messages for the IMAP backend: Z-Push News for 12/06/2012 Thanks to Franscisco aka fmbiete the IMAP backend users now have HTML email support on their devices. He also implemented stars (todo flags) and added some other fixes to the IMAP backend. B...

Oh, right right... should I use MYV6HERE::1 as the default gateway for IPv6 or can I use airway's link-local address?

ICMPv6 is critical to IPv6 and it won't work without it, unlike IPv4 where you can get away with blocking it at the expense of breaking things like path MTU discovery. I generally don't recommend filtering any ICMP for best performance. I had that in to explicitly allow ICMPv6 (any type) , since th...

Just as a follow-up, I've been messing with this and it seems to be related to ip6tables entries. I'm narrowing down the suspects. Seems that the default DROP policy for INPUT is the culprit, not matching some packets, even when there is a explicit rule to allow them through. One more look at the i...

Seth, Since you're the one that usually runs the show (CTO and all...) , I want to ask: what are your sysctl settings for your batch of Supermicros when you had them? I'm looking at mine and I could squeeze from 1MB/s with the default, I am doing about 8MB/s on a 1Gbps full duplex with a 6128 mtu (s...

Hello, For a while now I've been fighting off what many of us need to fight off: bruteforce attacks to various services, in this case ssh, imap and smtp. I have tried tools like fail2ban and similar, but only one (which its name escapes me) actually worked, but running it was cumbersome (runs proper...

Good enough for me. Thanks, Seth!

Hey Seth,

Since we couldn't find this out, can we just switch the port back to jumbo frames and Gigabit?

Its set. eth0 Link encap:Ethernet HWaddr 00:25:90:00:72:B4 inet addr:74.118.152.82 Bcast:74.118.152.87 Mask:255.255.255.248 inet6 addr: 2607:fe70:17::3/64 Scope:Global inet6 addr: 2607:fe70:17::5/64 Scope:Global inet6 addr: 2607:fe70:17::4/64 Scope:Global inet6 addr: fe80::225:90ff:fe00:72b4/64 Scop...

Well, I've gone through and exhausted all I could to try and find out whats up with this, but to no avail. I am out of ideas and can't figure this out for the life of me. Maybe it lies on the sysctl settings? Does it need IPv6 forwarding (though I doubt it since its on the same interface that has ba...

You have no link-local IPv6 address?

That is pretty much what I do, except in another fashion because of the fact I don't have a Debian system (I strongly dislike Debian) : #!/bin/bash DEVS="eth0" for IFACE in $DEVS; do for ADDR in $(ip -6 addr show dev $IFACE | grep inet6 | gawk '{print $2}' | grep 2607 | grep -v '::2'); do ...

Hello, There's been a few issues with using IPv6 which I know is just missing more configuration or just the way I have it configured. The issue is, I have multiple IPv6 addresses aliased to eth0 and it never takes the desired address to connect to other services, thus, when running traceroute6 or o...

dkimproxy works on my Postfix install, just like normal chained filtering does... I am not fond of having multiple Perl processes there, but since its not a proper application with threading, I cannot ask more. It works, and it does its work as it was designed to. I havn't benchmarked it since my s...
