NSIS on an embedded platform
by Bertrand Goareguer 16 Oct '07

16 Oct '07

Hi, I've just ported NSIS 0.5.1-dev to an embedded device (big endian architecture) and I went through a few bugs: 1- It did not compile with uClibc because the file ifaddrs.h was missing. This is a file from the Glibc. Looking at the code, it only concerns the functions dealing with reading the system routing table (instead of taking it from the configuration file). So I just removed everything related to these functions and the problem was solved. 2- I haven't got OpenSSL yet on my board. The configure script detects that the library is missing, but there is a compilation error in the GistMAEntry.cpp file. The concerned functions are GistMAEntry::bindTCP and GistMAEntry::setSock. I managed to get rid of the problem by adding the preprocessor check "ifdef OPENSSL_FOUND" at those 2 places. If OpenSSL was not found, I just deleted everything related to TCPTLSSocket. 3- When communicating with an NSIS aware router (in fact, a Linux PC configured as a router with the NSIS implementation) the messages are received but the bandwidths are all set to 0. 4- The SID field of the messages received on the board are correct but the SID in the RESPONSE message (sent from the board to the router) are no the same (00040004 00040004 00040004 00040004 in the RESERVE becomes 00040001 00040004 00040004 00040004 in the RESPONSE). I saw that there was an implementation for OpenWrt, but this seems to be a package file. Would it be possible to get the sources ? Regards, Bertrand

NAT/FW NSLP question

Dear all, I have some problems in testing the NAT/FW NSLP.My testbed has 3 nodes[NI/NF/NR]and I want to create pinholes in the NF using the command shown below.But after runing the command,I got no response and the iptables rule didn't be configured. ./nsis-natfw --create -s 192.168.1.1 -d 172.16.0.1 --sport 5624 --dport 4612 --debug 0 NI NF NR 192.168.1.1-------192.168.1.2/172.16.0.2------172.16.0.1 I have tested the ping tool(using ./nsis-ping 172.16.0.1) and the Diagnostics NSLP（using ./nsis-diag 172.16.0.1）at NI,and they have no problem.The NSIS version is nsis-0.5.1-dev and the OS is FC3. I got the following results at the nodes using ethereal.
