Sorry typo. Change > struct ping_header_t { > unsigned char version : 8; > unsigned char version : 8; > unsigned short length; > unsigned int seq; > } to: struct ping_header_t { unsigned char version : 8; unsigned char hops : 8; unsigned short length; unsigned int seq; }

There are some checks to detect a legacy NAT, i.e. a NAT that is not GIST-aware. They depend on checking IP addresses. See section 7.2.1 of http://www.ietf.org/internet-drafts/draft-ietf-nsis-ntlp-15.txt "If S=1, the receiver MUST check the source address in the IP header against the interface-address in the NLI, and if these addresses do not match this indicates that a legacy NAT has been found." I recommend using our wireshark/ethereal dissector to capture the packets and take a closer look at the packets. The legacy NAT detection is not well tested yet, so you MAY be hitting a bug. If you can identify who is complaining about which packet, I would like to take a look at this packet. You can also take a look at the debug output right before the error message. Copy/Pasted from your mail: (warn) *** Dmode message from : 100.0.2.2:4> *** (info) GIST message: Version = 1 Hop Count = 4 NSLP ID = 3 Message length = 112 (info) Type = RESPONSE (info) S flag = 0 (info) R flag = 0 (info) E flag = 0 (info) GistMriPathCoupled: length = 56 (info) Direction = Upstream (info) Source IP = 100.0.0.1 (info) Dest IP = 100.0.9.2 (info) GistSessionId: length = 20 (info) 0a000000 0a000000 0a000000 0a000000 (info) GistNetworkLayerInfo: length = 28 (info) IntAddr = 100.0.2.2 (info) RouteStateValidityTime = 100000 (info) GistQueryCookie: length = 36 Here you can see what the source IP address (first line), what the S-flag is set to (8th line), and what the IP address in the NLI (GistNetworkLayerInfo) is. Look at these values in the packet that triggers the legacy NAT error message and you might find out what is going on. Just to make sure: You have no NAT in your setup, right? > > DataSize: 268, HeaderLength: 12, Calc: 268(crit) > *** GistException: Invalid ping message. Length invalid *** The code checks whether or not all 3 of these values are equal, i.e. DataSize == HeaderLength == Calc. Obviously this is wrong in this message. *sigh* I just figured out what the problem is. 268 = 256 + 12. HeaderLength is defined as 8 bits, i.e. wraps around at 256, hence the value of 12. If I am reading my code correctly, the diagnostics NSLP will have the same problem. Seems like we never tried so many nodes. Are you familiar with C? If so, you can go into nslp/ping/PingMessage.h and modify struct ping_header_t. I suggest something like: struct ping_header_t { unsigned char version : 8; unsigned char version : 8; unsigned short length; unsigned int seq; } That should help. Christian

GIST Invalid ping message Length invalid
by Julien Lange 30 Apr '08

Hello, Sorry to bother you again but I am definitely facing some troubles trying to get opennsis to work... 1. Trying to nsis-ping through (from host1 to host3) my test network (see http://users.skynet.be/ilove/lab.png) I got a "invalid ping exception" in the node "router1"... I don't understand what does that mean, can someone help me? (I attached the trace from router1). 2. I wonder how nsis "learn" the routing table. In my test network, I use zebra as a routing daemon and then I run nsis (automatically using netkit). But the nsis doesn't work out of the box... I mean I have to kill nsis and run it again to have to result.. Otherwise I get: ------------------------------------ *** GistException: findOutgoingLocalAddress failed: No local address was found for this destination address (100.0.0.1). Please check your configuration * ------------------------------------ As soon as I have killed and restarted nsis, I can ping the "next" node... 3. On the node router3 or router5, depending on how the routing is made, I got sometimes an error saying that I'm using a "legacy NAT"... Where does this come from? 4. I'm sorry, I have tested Christan's patch, yet... A bit overbooked at the moment, but i'll do it! Thank you very much in advance, Julien. ------------------------------------------- Invalid ping message trace ------------------------------------------- *** API-Call RecvMessage() *** (info) nslp_data : d (info) nd_size : 268 (info) nslp_id : 0x0003 (info) sid : (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 ( info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x 00 (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 (info) (info) mri->msgRoutingMethod : 0x0000 (info) mri->s : 0 (info) mri->f : 0 (info) mri->t : 0 (info) mri->p : 0 (info) mri->ipVersion : 0x04 (info) mri->reserved : 0x00 (info) mri->d : 1 (info) mri->b : 0 (info) mri->a : 0 (info) mri->srcAddr : 100.0.0.1 (info) mri->destAddr : 100.0.9.2 (info) mri->srcPrefix : 0x20 (info) mri->destPrefix : 0x20 (info) mri->protocol : 0x00 (info) mri->diffserv_field : 0x00 (info) reliable : 0 (info) security : 0 (info) explicitlyRouted : 0 (info) noGistState : 0 (info) ip_ttl : 0 (info) ip_distance : 0 DataSize: 268, HeaderLength: 12, Calc: 268(crit) *** GistException: Invalid ping message.

RE: [Nsis_imp] Testing openNSIS in Netkit

Sounds like a bug in our routing table reading code then. We set the wrong 5 bits. Now the interesting question is: What happens if you set readRoutingTable = no in the nsis.conf of the router? Does it still output 255.255.255.31 on startup? If so, I will check how to fix this ASAP. We always use /8 /16 or /24 as netmasks, so this never came up ...

Hi, as the error message indicates, most likely your configuration (e.g. nsis.conf) is wrong. Can you please send me the output when starting all the 3 nsis instances when adding --debug 2?

Testing openNSIS in Netkit
by Julien Lange 28 Apr '08

28 Apr '08

Hello, I've been triyng to test openNSIS using Netkit (http://www.netkit.org/) for some days without success. I use opennsis v0.5.0. My first test implies two hosts and one router (see description below). When I run nsis daemon on the two hosts but not on the router, everything works fine (ie I can "nsis-ping" them in both direction). But as soon as I run nsis daemon also on the router, the hosts can't communicate with each other, neiter with the router. I got this error from the router's stdout (trying to ping H1 from H2): --------------------------- *** GistException: findOutgoingLocalAddress failed: No local address was found for this destination address (192.168.0.1). Please check your configuration *** --------------------------- I tried to specify the ip addresses manually in nsis.conf, with the same results. Do you have some advice to help to solve this? Thank you very much in advance, Julien. ------------------------------------------------------ Here is the description of the test network: ------ - H1 - eth0:192.168.0.1 ------ . .
