Re: ssh port forwarding CPU utilization

Strangely enough, my solution was to apply ssh compression to an already-compressed (Tight)VNC protocol. ssh -C has provided worlds of stability! I'm no longer worried about crashing the Mikrotik remote-displaying a console session. I'm typically doing this over links that have <5Mb/s links, so filt...

ssh port forwarding CPU utilization

I'm using ssh port forwarding through a one-CPU Mikrotik (usually a 751U-2HnD) to access VNC servers at the remote end. The client isn't busy. The server isn't busy. But, the poor CPU on the Mikrotik spikes to the point where occasionally it bogs down, resets. Has anyone else seen this sort of thing...

Anyone have issues with Mikrotik NTP servers not coming up?

I have a few Mikrotiks configured as simple NTP servers using the optional NTP package, like so: [2400@baud] /system ntp server> print enabled: yes broadcast: no multicast: no manycast: no broadcast-addresses: [2400@baud] /system ntp client> print enabled: yes mode: unicast primary-ntp: x.x.x.1 seco...

Re: v6.30.1 bugfix release

How does one enable NTP Server debugging??

I have the NTP Server from all_packages-mipsbe-6.11.zip installed and working on my RB-751.

I wanted to debug something, so I enable ntp debug logging -- something I've done with other services many times before.

Nothing gets logged.

Is there a "topics" setting besides "ntp" I should be using??

I saw a similar flooding of messages with a Nook Color.

I'd argue that the logging for that message shouldn't be at "info" level but more like debug.

The Mikrotik SMB implementation expects "guest" and fails. Here's the relevant packet exchange: 192....

Re: Issues with MTU>1504 bytes on Intel NICs like 82575EB

Intel doesn't make much of an effort to sync their drivers to upstream Linux kernel source. What's in the Linux kernel is basically "enough to get you up and running". Note that many distros use the drivers from Intel directly rather than from the Linux kernel. I don't have nearly enough data to say...

Per-connection.

I know there's PCC, but that does things based off a hash, not true round robin.

ROS 5.8
IPSec and IPSec/L2TP does not work with Mac OS X. Works fine with windows and linux.
I just set up MacOS 10.6.8 as an L2TP/IPSec client to ROS 5.8.
