[Serusers] find_export: <append_hf> not found

Jimmy, http://www.informatik.uni-bremen.de/~prelle/terena/cookbook/Cookbook_D2/ ch04s07.html Hi read it all, and it is really interesting. However I came across some errors. Following the link's instructions I modified my ser.cfg but got these errors. [...] 0(14133) find_export: <search> not found 0(14133) find_export: <search> not found 0(14133) parse error (111,63-64): unknown command, missing loadmodule? [...] 0(14133) find_export: <search> not found 0(14133) find_export: <search> not found 0(14133) parse error (175,66-67): unknown command, missing loadmodule? [...] 0(14133) find_export: <append_hf> not found 0(14133) find_export: <append_hf> not found 0(14133) parse error (183,41-42): unknown command, missing loadmodule? Searching lines 111,175 and 183 in my ser.cfg, I found the following: Line 111 if (method == "REGISTER" || ! search("^Record-Route:")) Line 175 if (uri=~"[@:](192\.168\.|10\.|172\.16)" && !search("^Route:")){ Line 183 append_hf("P-Behind-NAT: Yes\r\n"); There is some kind of error with the commands "search" and "append_hf". Any ideas ? Regards, Lucas -- No virus found in this outgoing message. Checked by AVG Anti-Virus. Version: 7.0.300 / Virus Database: 265.8.4 - Release Date: 01/02/2005
