Re: WinSCP mega-slowness
Well, it's good to know I'm not the only one seing this. Right now both machines are running FreeBSD, since I gave up on waiting for Windows to copy the files. The CPU load on Window when sending 1 meg per second is usually about 30%, while the Unix box is only at 1-2%. When I have 2 Unix boxes sending/receiving, I think the load is like 4-5% on both. I'm building a bunch of packages right now, so I can't get the exact number. I could try the openssh patch later in the week, that would be great if there was a unix-side fix for this. Of course as I run FreeBSD more, and Windows less, the problem will go away, too. thanks!

Re: WinSCP mega-slowness
I can try that. I'm not sure how to use Samba3, though. I was trying to help a friend use Samba, but I was use to Sama2, and Samba3 apparently recquires a smb.conf file. You use to be able to just do everything from the command line, like (I think): smbclient //server/share /mnt/pnt -o username=username,password=password Apparently that doesnt work anymore, and I havent had time to figure out the new way. I think smbclient isn't even part of Samab3 (it could find it after installing it). On 2/20/06, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Well, it's good to know I'm not the only one seing this.
