- Well, this is probably a good time for an update.
-
- I've tried out the bsd-emul library from Markus on DNet on my Amix
- 2.1 machine. The initial attempt didn't go. Dnet itself started but
- none of the servers would start. One problem appeared to be that dnet
- was trying to access port number 9492 on the Unix side, and it
- shouldn't have been. Tracking down the call to startserver() I found
- that reading the port number from the AmigaDOS side was pretty basic
- stuff, and so I have no explanation for this one, but I'll look into
- it more later.
-
- The second problem was that the pty code still needs to be the SVR4
- method instead of the BSD method, even with the emulation library, and
- my ifdef's (compiling on "svr4" but without that #define) was causing
- the wrong pty code to be used. I have since rebuilt that version, but
- have lost my beta tester over the holidays.
-
- I have heard from a few people who would like to try out any changes.
- So I'm going to be sending source code to these two folks:
-
- Dan Shein <rehab1!rehab2!dan@cbmvax.cbm.commodore.com>
- Joel Justen <crpi!joel@uunet.UU.NET>
-
- Also, on Monday I'll post a uuencoded binary for the bsd emulation
- library. My gcc doesn't have the PIC patches installed so I can't
- generate a shared object; hence they will be link libraries.
-
- I will be posting binaries for dnet here as well, zoo'ed and uuencoded.
- These should be considered beta versions; they may work, and they may
- not. They do allow connections and the STERM appears to work fine. If
- the above port number and pty problems have been corrected by my latest
- changes, then there should be little left to do. (Although I still
- have high hopes of doing the POSIX conversion, but if the emul library
- works it won't be quite as critical anymore.)

- You're confusing a low-level format with a high-level format. This is
- common given that people use one command to do both things on most
- home computers, ie. AmigaDOS, MessyDOS, MacOS, ...
-
- The Unix "format" command is a low-level format -- it prepares the
- media to accept data laid out in 11 sectors, 80 tracks, double-sided.
- It does not write directory entries or any of that on the floppy. That's
- what the high-level format does. There is currently no high-level format
- for the AmigaDOS filesystem(s) under Amix. (Although my virtual
- filesystem under Amix will soon have the equivalent "mkfs" command
- which will do what you want.)
-
- >Does BRU work for 1.3 <-> 2.0?
-
- Yes. And it is typically what I use, when I need to write to the
- AmigaDOS side (although I use bru on tape instead of floppy).
-
- Those folks that are using the VFS: what's happening? Should I go
- ahead and release the code? Has anyone had problems reading AmigaDOS
- files from Amix? (Besides the fact that it's sloooow -- I know about
- that one. :-)
