* (Merged the 0.5-pre branch back into CVS HEAD)
* Replaced the old tunnel routing crypto with the one specified in
router/doc/tunnel-alt.html, including updates to the web console to view
and tweak it.
* Provide the means for routers to reject tunnel requests with a wider
range of responses:
probabalistic rejection, due to approaching overload
transient rejection, due to temporary overload
bandwidth rejection, due to persistent bandwidth overload
critical rejection, due to general router fault (or imminent shutdown)
The different responses are factored into the profiles accordingly.
* Replaced the old I2CP tunnel related options (tunnels.depthInbound, etc)
with a series of new properties, relevent to the new tunnel routing code:
inbound.nickname (used on the console)
inbound.quantity (# of tunnels to use in any leaseSets)
inbound.backupQuantity (# of tunnels to keep in the ready)
inbound.length (# of remote peers in the tunnel)
inbound.lengthVariance (if > 0, permute the length by adding a random #
up to the variance. if < 0, permute the length
by adding or subtracting a random # up to the
variance)
outbound.* (same as the inbound, except for the, uh, outbound tunnels
in that client's pool)
There are other options, and more will be added later, but the above are
the most relevent ones.
* Replaced Jetty 4.2.21 with Jetty 5.1.2
* Compress all profile data on disk.
* Adjust the reseeding functionality to work even when the JVM's http proxy
is set.
* Enable a poor-man's interactive-flow in the streaming lib by choking the
max window size.
* Reduced the default streaming lib max message size to 16KB (though still
configurable by the user), also doubling the default maximum window
size.
* Replaced the RouterIdentity in a Lease with its SHA256 hash.
* Reduced the overall I2NP message checksum from a full 32 byte SHA256 to
the first byte of the SHA256.
* Added a new "netId" flag to let routers drop references to other routers
who we won't be able to talk to.
* Extended the timestamper to get a second (or third) opinion whenever it
wants to actually adjust the clock offset.
* Replaced that kludge of a timestamp I2NP message with a full blown
DateMessage.
* Substantial memory optimizations within the router and the SDK to reduce
GC churn. Client apps and the streaming libs have not been tuned,
however.
* More bugfixes thank you can shake a stick at.
2005-02-13 jrandom
* Updated jbigi source to handle 64bit CPUs. The bundled jbigi.jar still
only contains 32bit versions, so build your own, placing libjbigi.so in
your install dir if necessary. (thanks mule!)
* Added support for libjbigi-$os-athlon64 to NativeBigInteger and CPUID
(thanks spaetz!)

<p>You do <i>not</i> need to allow inbound TCP connections - outbound connections work with no

While I2P will work adequately behind a firewall, your speeds and network integration will generally improve
|
|
|
|
|
if you open up your port (generally 8887) to both UDP and TCP, and enable inbound TCP above.
|
|
|
|
|
If you think you have opened up your firewall and I2P still thinks you are firewalled, remember
|
|
|
|
|
that you may have multiple firewalls, for example both software packages and external hardware routers.
|
2009-03-02 16:07:48 +00:00
|
|
|
If there is an error, the <a href="logs.jsp">logs</a> may also help diagnose the problem.
|
2008-09-23 18:48:59 +00:00

<ul>
|
|
|
|
|
<li><b>OK</b> - Your UDP port does not appear to be firewalled.
|
|
|
|
|
<li><b>Firewalled</b> - Your UDP port appears to be firewalled.
|
|
|
|
|
As the firewall detection methods are not 100% reliable, this may occasionally be displayed in error.
|
|
|
|
|
However, if it appears consistently, you should check whether both your external and internal
|
2009-04-25 02:47:28 +00:00
|
|
|
firewalls are open on port 8887. I2P will work fine when firewalled, there is no reason for concern.
|
|
|
|
|
When firewalled, the router uses "introducers" to relay inbound connections.
|
|
|
|
|
However, you will get more participating traffic and help the network more if you can open your
|
|
|
|
|
firewall(s). If you think you have already done so, remember that you may have both a hardware
|
|
|
|
|
and a software firewall, or be behind an additional, institutional firewall you cannot control.
|
|
|
|
|
Also, some routers cannot correctly forward both TCP and UDP on a single port, or may have other
|
|
|
|
|
limitations or bugs that prevent them from passing traffic through to I2P.
|
2008-09-23 18:48:59 +00:00
|
|
|
<li><b>Testing</b> - The router is currently testing whether your UDP port is firewalled.
|
2008-10-26 17:24:11 +00:00
|
|
|
<li><b>Hidden</b> - The router is not configured to publish its address,
|
|
|
|
|
therefore it does not expect incoming connections.
|
2008-09-23 18:48:59 +00:00
|
|
|
<li><b>WARN - Firewalled and Fast</b> - You have configured I2P to share more than 128KBps of bandwidth,
|
|
|
|
|
but you are firewalled. While I2P will work fine in this configuration, if you really have
|
|
|
|
|
over 128KBps of bandwidth to share, it will be much more helpful to the network if
|
|
|
|
|
you open your firewall.
|
|
|
|
|
<li><b>WARN - Firewalled and Floodfill</b> - You have configured I2P to be a floodfill router, but
|
|
|
|
|
you are firewalled. For best participation as a floodfill router, you should open your firewall.
|
|
|
|
|
<li><b>WARN - Firewalled with Inbound TCP Enabled</b> - You have configured inbound TCP, however
|
|
|
|
|
your UDP port is firewalled, and therefore it is likely that your TCP port is firewalled as well.
|
|
|
|
|
If your TCP port is firewalled with inbound TCP enabled, routers will not be able to contact
|
|
|
|
|
you via TCP, which will hurt the network. Please open your firewall or disable inbound TCP above.
|
2008-12-03 18:53:57 +00:00
|
|
|
<li><b>WARN - Firewalled with UDP Disabled</b> -
|
|
|
|
|
You have configured inbound TCP, however
|
|
|
|
|
you have disabled UDP. You appear to be firewalled on TCP, therefore your router cannot
|
|
|
|
|
accept inbound connections.
|
|
|
|
|
Please open your firewall or enable UDP.
|
2008-10-26 17:24:11 +00:00
|
|
|
<li><b>ERR - Clock Skew</b> - Your system's clock is skewed, which will make it difficult
|
|
|
|
|
to participate in the network. Correct your clock setting if this error persists.
|
2008-09-23 18:48:59 +00:00
|
|
|
<li><b>ERR - Private TCP Address</b> - You must never advertise an unroutable IP address such as
|
|
|
|
|
127.0.0.1 or 192.168.1.1 as your external address. Correct the address or disable inbound TCP above.
|
|
|
|
|
<li><b>ERR - SymmetricNAT</b> - I2P detected that you are firewalled by a Symmetric NAT.
|
2009-04-25 02:47:28 +00:00
|
|
|
I2P does not work well behind this type of firewall. You will probably not be able to
|
|
|
|
|
accept inbound connections, which will limit your participation in the network.
|
2008-09-23 18:48:59 +00:00
|
|
|
<li><b>ERR - UDP Port In Use - Set i2np.udp.internalPort=xxxx in advanced config and restart</b> -
|
|
|
|
|
I2P was unable to bind to port 8887 or other configured port.
|
|
|
|
|
Check to see if another program is using port 8887. If so, stop that program or configure
|
|
|
|
|
I2P to use a different port. This may be a transient error, if the other program is no longer
|
|
|
|
|
using the port. However, a restart is always required after this error.
|
2008-12-03 18:53:57 +00:00
|
|
|
<li><b>ERR - UDP Disabled and Inbound TCP host/port not set</b> -
|
|
|
|
|
You have not configured inbound TCP with a hostname and port above, however
|
|
|
|
|
you have disabled UDP. Therefore your router cannot accept inbound connections.
|
|
|
|
|
Please configure a TCP host and port above or enable UDP.
|
2009-03-02 16:07:48 +00:00
|
|
|
<li><b>ERR - Client Manager I2CP Error - check logs</b> -
|
|
|
|
|
This is usually due to a port 7654 conflict. Check the logs to verify. Do you have another I2P instance running?
|
|
|
|
|
Stop the conflicting program and restart I2P.

<p>
|

|
This setting causes your router identity to be regenerated every time your IP address
|
|
|
|
|
changes. If you have a dynamic IP this option can speed up your reintegration into
|
|
|
|
|
the network (since people will have shitlisted your old router identity), and, for
|
|
|
|
|
very weak adversaries, help frustrate trivial
|
|
|
|
|
<a href="http://www.i2p.net/how_threatmodel#intersection">intersection
|
|
|
|
|
attacks</a> against the NetDB. Your different router identities would only be
|
|
|
|
|
'hidden' among other I2P users at your ISP, and further analysis would link
|
|
|
|
|
the router identities further.</p>
|
|
|
|
|
<p>Note that when I2P detects an IP address change, it will automatically
|
|
|
|
|
initiate a restart in order to rekey and to disconnect from peers before they
|
|
|
|
|
update their profiles - any long lasting client connections will be disconnected,
|
|
|
|
|
though such would likely already be the case anyway, since the IP address changed.
