Hi, > Your patch looks like a good first attempt. Here are some comments: Okay, I edited the code according to your comments; I'll make a patch available later the evening, this time including the carloads of man pages that mention /etc/services. > want to hash the service names scanned from earlier files and skip > any that are found to match in later files. I don't see why we should do this, since /etc/services is read before /etc/defaults/services, so if a protocol name appears in both files, the entry from /etc/services matches first and getservent() returns, ignoring all subsequent entries. I agree this could be done better: Now that I looked at the original code, I found it worth being completely rewritten...at least to get rid of all these "goto" statements. Furthermore, I believe it's much more elegant to read both files once and merge them into a memory buffer. This way, we could check/avoid duplicate entries while parsing the files, and would additionally have some basic mechanism to explicitly disable a service, no matter what keyword or special character it will be to do so; the basics would already be there. Furthermore, we could kiss those file I/O functions goodbye, since there would only be a small memory buffer to be "rewinded" by setservent(), and no need to keep the files open. Finally, I do believe a few more comments in the code would be nice. :) So, if this sounds good to you, I'll start working.
