Configuration / Re: SNMP configuration

« on: May 03, 2017, 11:51:21 PM »

Hi,

SNMP is disabled by default in v.3, but can be enabled by setting SNMPD=enable in wanos.conf. The default community is wanos_ro_snmp.

But probably the easiest method to get SNMP running on v.3.2.3 and at the same time fix some important typos in the default snmpd.conf is to run the following patch:

wget http://wanos.co/updateinfo/snmp_update_v.3.2.3.sh
bash snmp_update_v.3.2.3.sh

Some SNMP info has been added in the Admin Guide at:

Configuration / Re: Force speed and duplex

« on: May 02, 2017, 02:20:09 PM »

The interfaces are auto-negotiated by default. The recommendation is to try as far as possible to use auto and enable auto negotiation on the switch/router side so that negotiation succeeds.

For the corner cases, when the recommended method is not possible, here is how to set it manually:

ethtool -s wan0 speed 100 duplex full
ethtool -s lan0 speed 100 duplex full

Once you are happy that the commands work as expected and you want the commands to run automatically after reboots etc, then add them to /etc/wanos/ethtool_options file e.g.:

ETHTOOL_OPTS_WAN0=speed 100 duplex full autoneg off

We'll usually do something like this for the client remotely, but you can run them, just make absolutely sure there aren't typos in the line.

Features / Re: PLR Feature

« on: May 02, 2017, 08:56:39 AM »

Hi Aels,

PLR works in either IPComp or UDP. Note though if you have some NAT configurations that in v.3 some PLR control packets between the appliances are IPComp encapsulated whether UDP encapsulation is enabled or not.

The first file copy, gets compression and deduplication. Since it is the first time to see the file, byte-cache/deduplication hits are low because it is still learning the file. On the second transfer the hit ratio is high, since it is mostly the same file.

Depending on data type, Byte-Caching cold compression ratio (first copy) is similar to stream compression, since even in a cold transfer there are duplicate "words" that can be removed. As the dictionary of words (datastore) grows, the higher the cold compression hit ratio.

Configuration / Re: Tunnel mode peer not coming up, Idle

« on: April 27, 2017, 02:04:58 PM »

Ok, yes, the inbound internet traffic on the B side is probably not redirected to the wan0 address.

There are a couple ways to work around it. I think the quick and easiest would be to fire up a second VM server on the Internet side and enable a Squid proxy on that side with a route directing traffic to the server-A IP to Wanos-B wan0. Then your traffic would flow in both directions and it should work as expected.

On Amazon AWS we have also done it with only wanos v.4 on the AWS side. But I recommend the easier method above since the setup is almost complete.

Configuration / Re: Tunnel mode peer not coming up, Idle

« on: April 27, 2017, 08:05:28 AM »

Hi Ovez,

Steps in a nutshell are:
Deploy VM with one nic connected to the network
Configure IP address and GW (WAN Router)
Configure Traffic Policies to match local subnets (Source) to remote subnets (Destination)
Add default #99 bypass to pass-through all other subnets traffic
(v.2.x to v.3.x) Configure Multisite subnets that match traffic policies with remote peer IP address (start with site-0)
(or v.4.x) Configure Tunnel Policies that match remote subnets with remote peer ip
Switch to UDP encapsulation
Switch to Tunnel deployment
Configure Server-A in Site-A to use Wanos-A as default gateway
Configure Server-B in Site-B to use Wanos-B as default gateway
Test non-bypassed TCP traffic between Server-A and Server-B (e.g. HTTP, FTP)

One side "Up/Active" while the other side is "Idle" usually indicates asymmetric/one way traffic flow.
Since Wanos-2 shows up, it means Wanos-1 is probably configured OK.
Look to see that the Servers at Site-2 has Wanos-2 as default GW.

Once the setup is functional between Server-1 and Server-2 with default gateways, then next look at configuring more interesting routing setups with Policy based routing etc.

Note a difference between v.3 and v.4 tunnel mode:
v.2-v.3 Only optimized traffic is tunneled while the peers are online e.g. excluding ICMP
v.4 All traffic is tunneled, including ICMP

Hi Aels,

It could be that the password typed is more than 12 characters, but only the first 12 is accepted.
