It took some figuring out and kernel recompiles and other tricks, but it works. EXCEPT that I haven't figured out how to get the function keys in emacs to work like without X. I mean, I made a nice vt100.el and keypad.el so that the PgUp key scrolls one screen up, the - and + keys on the numeric keypad do cut and paste, and so on. This all worked nicely on the VAX/VMS, and on Linux emacs. But now, running emacs in X, these keys don't work anymore. I tried to set the TERM environment variable to vt100 (is default xterm) in the xterm window right before I launch emacs &, and emacs seems to see this value (M-! echo $TERM shows indeed vt100), but to no avail. Is there something I need to know about X to get my function keys back?

You seem to totally ignore the inexpensive alternative of DC-600 tapes that use the QIC-02 code, the original code for tapes with Linux. I've used a Wangtek 5150EQ with Linux for close to a year, it's much faster than the floppy based solutions, and you can get 250mb uncompressed on DC6250 tapes.

Shouldn't this be the job of something like /etc/gettytab (gettydefs?)? I think this is a wrong procedure in SLS. I had no end of trouble because of this. The correct way, I think, is the following: SLS uses shadow password, which uses the file /etc/login.defs for setting up defaults for all login sessions. You will find a line there which sets up the terminals. It looks for a file called /etc/consoles, which should look like this: console tty1 console tty2 ............ console tty12 ............ vt100 ttyS1 ............ and so on. The whole thing is quite clearly explained in /etc/login.defs, with plenty of comments.

Well, here comes one from someone who used one in the comany he worked for :-) We used it as a news/mail-machine because the dos-stuff was to annoying, nothing really worked as good as the typical sendmail/cnews/taylor_uucp-stuff, but instead did cost money... We used it to fax away via modem 400faxes at one night, it used 10h to do this, and it was first-class-quality output...

One big way is the lack of experimenting, and the lack of wanting or >needing the stock gnu-type tools. Commercial versions lack the features the gnu-type tools have. But on the other hand, this can be very expensive to the company because we had to invest a lot of time into the machine to do what we wanted. It would have been faster and probably cheaper to buy solutions from commercial companies, at least in the shorter term, but it would never have worked that nicely in the end... ...I installed a 1GB-scsi-drive at 4am from home via modem.

The offending code is in device.c: static int scan_dir(DEVICE *dev,char *parent,int number) { DIR *dp; struct dirent *dir; char *start; if ((dp = opendir(parent)) == NULL) die("opendir %s: %s",parent,strerror(errno)); *(start = strchr(parent,0)) = '/'; while (dir = readdir(dp)) { strcpy(start+1,dir->d_name); if (stat(parent,&dev->st) < 0) die("stat %s: %s",parent,strerror(errno)); if (S_ISBLK(dev->st.st_mode) && dev->st.st_rdev == number) return 1; if (S_ISDIR(dev->st.st_mode) && strcmp(dir->d_name,".") && strcmp(dir->d_name,"..") && scan_dir(dev,parent,number)) return 1; } (void) closedir(dp); *start = 0; return 0; } What's happening is that lilo goes groveling in /dev/fd, which is a link to /proc/self/fd, and guess what! One of the files in /proc/self/fd is the very same directory /dev/fd, and so lilo continues to grovel because it assumes there are no loops in the file system. The fix is to keep a list of inode numbers currently being visited, and to cut off the looping when such an inode number is reached. I'll post a patch when I have one. -- Norman Ramsey norman@bellcore.com ------------------------------ ** FOR YOUR REFERENCE ** The service address, to which questions about the list itself and requests to be added to or deleted from it should be directed, is: Internet: Linux-Admin-Request@NEWS-DIGESTS.MIT.EDU You can send mail to the entire list (and comp.os.linux.admin) via: Internet: Linux-Admin@NEWS-DIGESTS.MIT.EDU Linux may be obtained via one of these FTP sites: nic.funet.fi pub/OS/Linux tsx-11.mit.edu pub/linux sunsite.unc.edu pub/Linux End of Linux-Admin Digest ******************************
