I am currently stuck on FTape. I have a Conner 250MB tape drive. I have also just done a clean install of the Slackware 2.0.0 distribution. The command 'mt -f /dev/ftape retension' works fine, but to tar to the /dev/ftape device results in 'I/O error'. The Conner manual suggests a jumper be removed from the drive for Unix operating systems that has something to do with auto-positioning. This didn't make a difference.

Date: 30 Aug 1994 17:08:49 GMT Reply-To: cisko@d0tokensun.fnal.gov Here are several [Q's] I have. 1) I was using textedit to edit a file. I saved the file & got the error message "Cannot save file: filesystem full". Or something similar. This is fine, except for 2 things. a) I have 120+MB free b) The file was successfully saved anyway. This happens anytime I save a file with textedit. 2) When I have any of the 2 filemanagers open I cannot save the workspace. The problem is definately with the filemanager. I can save the workspace when I don't have a filemanager running. 3) I cannot start rcp.statd. I get an error about a failed connection.

This means that when ftpd uses /bin/ls it gets translated by the system into ~ftp/bin/ls. Also you must use hard links rather than softlinks if you want to access a file that is outside the ftp directory tree. -- +----------------------------------------------------------------------------+ | John SAUNDERS - AARnet johns@rd.scitec.com.au - #include | | SCITEC Communication Systems - Phone +61 2 428 9541 - Fax +61 2 418 6954 | +----------------------------------------------------------------------------+ ------------------------------ From: huth@cs.tu-berlin.de (Frank Huth) Crossposted-To: comp.os.linux.help,comp.os.linux.misc Subject: Re: BRK key on older VT100 classs terminals?

Rubbish. 14.4kbps modems use the V32.bis protocol which permits data transfer at 14,400 _uncompressed_; if you also turn on data compression (V42.bis), you may achieve an effective transfer rate of 57600 kbps on compressible files.
