Sorry about my long delayed response. I worked most of Saturday playing around with ppp and various options in rc.conf trying to narrow the problem down to some kind of route problem. In the process I did find some routing problems and fixed them. But there was no improvement in the failure to keep an rsh or ftp session going over a serial port connection with my isp. I am going to start another thread under the title ``sio problems?'' and try to figure out what's wrong with my serial port. I suspect while sio4 works enough to start a link with my isp, it somehow fails at some point. I think the problem is the serial port configuration. I suspect the swap during bootup sio0 -> sio4 is the heart of the problem. With that in mind, I think you are right about a routing problem in the sense that the mapping of physical serial device (modem) to its virtual serial device (sio0 -> sio4) is mixed up somehow and that in turn creats the effect of a routing problem. Even if a fixed serial port system doesn't help, at least it will be one more problem fixed.

Thanks to Ted M and Mikhail G for the help on Fetchmail. I think I have narrowed the problem down to exclude any configuration mistakes in fetchmail or sendmail. I think I have a problem with my serial port sio0 (it has a 56k USR modem). In dmesg: dmesg | grep "sio": sio0: configured irq 22 not in bitmap of probed irqs 0 sio0: port may not be enabled sio0: <3COM PCI FaxModem> port 0x1000-0x1007 irq 22 at device 1.0 on pci7 sio0: moving to sio4 sio4: type 16550A fwohci0: OHCI version 1.10 (ROM=0) sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0 sio0: type 16550A sio1: configured irq 3 not in bitmap of probed irqs 0 sio1: port may not be enabled *sio4: 297 more interrupt-level buffer overflows (total 297) The last line shows an added messages that the sio4 has overflows. Notice that the sio0 (with 56k modem) has been remapped to sio4. Also, my isp uses standand ip/tcp (IPv4, not IPv6). I have both enabled in inetd.conf. My problem is that using the modem to connect to my isp, I can not get fetchmail, rsh, rlogin, or ftp to work. They all start just fine and then hang. I have to kill the user1 to get the tty1 back. I set this new box (6.2) up with a network connection to my old box (4.2) as a gateway. When the 4.2 box connects to the isp, I can use rsh, rlogin, fetchmail from the new box using the old box as the connection. This implies there is something wrong with the new box serial connection to my isp. However, from the new box (6.2) after starting the dial up connection on the serial port, I can use telnet to get to the isp shell account. What is the difference between how rsh uses the various ip/tcp protocols and how telnet? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Old 4.2 user, with 6.2 newbie questions
I am in the process of moving from 4.2-RELEASE on an old box to 6.2-RELEASE on a new box (Core 2 Duo, DG965WH mobo, GeForce 7600gs, 1G RAM, 400G sata drive). I need to figure out a couple of userland changes to the default 6.2 installation which took about an hour and went great. I have a shell account on my isp which runs 4.10-STABLE. In my old 4.2 box I have fetchmail set to log in, get mail and hand it over to local sendmail to put it in my local /var/mail/user directory on my old machine. I also use rsh (I know, don't) to log in to my shell account. I use my own sendmail to send mail out to various lists on the old box. I masquerade as my isp in sendmail, which puts the appropriate user name on my headers. Ok. In 6.2 box I've turned off local only mail (no submit.cf) and have sendmail maquerade working. I can send email out as a user, but I can't retrieve mail on my isp via fetchmail. I think ppp is configured correctly because I can telnet just fine to my shell account, but I can't rsh. It hangs after the password has been sent (yes you are not supposed to need a password with rlogin, but my isp uses one anyway for minium security). If I am root and switch during rsh/rlogin login to my username, I can get a little further along. I get the first few system announcements on the shell server, and then the terminal hangs. I have to kill the rlogin PID to get back the ttyN terminal. There also seems to be buffer overflows or conflicts between the mouse (on a usb port, usm0), 56k modem (PCI, sio0 remapped to sio4?), and printer (lpt0). In ppp, I use /dev/cuad4, despite the fact the modem is reported in dmesg as on sio0. Whatever is going on at some lower layer, all these devices work with random messages about stray irq's---so I am ignoring them at the moment. In other words, I can use dial-up, the mouse works, and the printer prints (via lp). Seems good enough for the moment. There have obviously been changes to the 6.2 base install that I don't know about that probably account for some of these problems. Unfortunately, most of these issues are no covered in the manuals that came with the CDs, or the coverage was out of date Suggestions on where to look, things to check and change would be greatly appreciated. At the moment I am more interested in getting correct behavior, than I am concerned with security. My first priority is getting fetchmail running. Here is the fetchmailrc dot file: defaults proto pop3 user mailname poll my.isp.com pass x set daemon 840 As user, I can run fetchmail at the command line, without an error message, but it also doesn't get and deliver any mail. I can send email to myself, but I am sure it never leaves the machine. The [EMAIL PROTECTED] is correct---so sendmail masquerade is working. For example, sendmail does not write: [EMAIL PROTECTED], as it would without masquerade. I changed the permissions on sendmail back to: $ ll -r-sr-xr-x 1 root wheel 583680 Jan 11 23:42 sendmail from 6.2 default: $ ll -rwsr-xr-x 1 root wheel 583680 Jan 11 23:42 sendmail I've tried it both ways and niether seems to make any difference. My general impression is that 6.2 has set up restrictions or modified rsh and fetcmail---or perhaps these are fine, but don't interact well with older verisons, i.e 4.10. Although I can ftp to my shell and down load files. Also I updated the ports via ftp as root, and everything took forever, but seems to work fine. For example I use Magicfilter which was not in the cd's, so from ports/printer, I downloaded Magicfilter, compiled and installed it and it works fine as a postscript filter for lpr. I know these are quite a few questions, but any suggestions on any of them would be much appreciated.
