Well, it's sort of your server. Truth be told I think it's both of our faults... :)

No, that's not what you're sending out, (or at least not what's causing the error condition) and that's what had me so confused. Attached is a file that I created by telnetting to port 70 of your server. This was so I could see exactly what your server was outputting.

On the "foo" lines, here's the problem - you seem to have put a spacer in the directory listing so the clients will just display an empty line. Nothing wrong with that, but here's what the server is spitting out:=20

i<tab>foo<tab>70

That's just like: iSomeText<tab>foo<tab>70 (which is handled correctly) the only difference being that SomeText is "" in this case. THAT is the problem. The "name" field is NULL in this situation.

I don't know if this violates the gopher protocol, the protocol says how things should be, but it doesn't explicitly disallow this situation. I'm going to fix the FORG so it works with this data, but if netscape and/or lynx isn't working with it, my suggestion would be to change the server so it doesn't send NULL name fields. The easiest way to do that would be to have it send one space " " instead of nothing. That way it doesn't get displayed as anything, and you're not messing clients up.

Like I said, I'll fix this in the FORG and the change should be in CVS in a few hours hopefully, but I'd recommend you tweak the server so this doesn't happen if you're having problems with clients other than just mine.

I'm sending this to the list too because I think it might be of wider interest - Cameron, does bucktooth ever do this? John, do you know if UMN gopherd ever does this? (I'll check if I get the time...)

What do you guys think? Is this a violation of gopher? --=20 David Allen http://opop.nols.com/ ---------------------------------------- Majority, n.: That quality that distinguishes a crime from a law
