well, actually I use wireless some of the time, both near the server and across the 28.8 link. But recently I've been on wired Ethernet since I had some grief with the internal wireless on the Thinkpad T30 (interoperting with 802.11 (not b) stuff in IBSS mode, and mysterious lockups perhaps similar to Kevin O (fbsd)'s problems). For IPsec, I am running transport mode from client to server; I am not doing any tunnel-mode across wireless at the moment. Do you run a strong connection? when near the server, sometimes. Across the 28.8 link, essentially never. Then I think things work, but it's too painful, and I really like the write-behind caching of wd mode. I am running fairly close to the head of NetBSD-current, I will be updating that to head soon again. My server is running i386 SMP at the moment and I do not appear to have any grief with coda on that front which is good (just a data point for peoples). If you are in the mood, build and install cfs, and then try using emacs in a cfs filesystem, which will create symlinks for emacs's own advisory locks when modified. I have been able to panic a 1.6-stable system doing this, with a 'ref cnt' panic in vput (I think count was zero when it should have been 1). Both emacs-in-coda and emacs-in-cfs seem to work. Note that cfs makes symlinks to nowhere to store IVs, as in .pvect_hex -> hex. symlinks in the ciphertext fs don't seem to have IVs (like the filenames themselves). The operation that seems to hose me when over the 28.8 line is (no cfs here): $ cd /coda/home/gdt/foo/bar $ mv /home/gdt/file . #from regular ffs on local disk But I have not really isolated things. Try having other competing traffic on the link too. Jan gave me hints to be able to checkpoint LOG/DATA/cache, so I will be more willing to experiment - rolling back to stable venus with hoarded bits is better than -init. I will have a look at doing some heavy CVS'ing on my setup and see what happens. I have been planning to do this anyway as I am playing with a larger project. Up til now my modus operandi is to "cvs co" a tree on the server and then hoard the data to my laptop, maybe do some small commits from the laptop to the cvs server when disconnected. As I said, I have not had many problems that cannot be laid at the feet of a dirty shutdown or my fat fingers... Do you have the _repository_ in Coda (shudder), or just your working area? CFS needs the following to play nice with coda: don't open files for write unless the user did, so that reading a file doesn't invoke store. (unix semantics are that open for write and not writing does not cause 'modification', but it does for coda) Without this, you get write-write conflicts from read-read operations. close files reasonably promptly, so one doesn't have stores hang until the next cfs access (gross patch to generated file) --- cfs_fh.c.~1~ Wed Mar 20 12:57:56 1996 +++ cfs_fh.c Mon Nov 8 11:19:22 1999 @@ -543,7 +543,9 @@ openfd=NULL; } +#if 0 if (mode==0) { mode=CFS_WRITE; } +#endif /* Phil Karn's hack for R/O file systems */ if ((fd=open(f->name,mode,0))<0 && errno == EROFS) { mode = CFS_READ; /* Force read and try again */ --- nfsproto_svr.c.~1~ Mon Nov 8 11:20:40 1999 +++ nfsproto_svr.c Mon Nov 8 11:21:27 1999 @@ -166,5 +166,6 @@ fprintf(stderr, "unable to free arguments"); exit(1); } + closeall(); return; }Received on 2002-12-13 09:38:02
