The routing table (static) gets mixed, i.e. the proper order of static routes is no longer maintained. Thus as soon as the kernel tries to establish a connection it doesn't get there. (This was pointed out for pl12 some months ago and still happens, Linus knows about it but so far not to many people have been reporting this and nobody was sure whether it is really a bug or just a (corrupted) installation. Here is what helps: In the inet.rc (or whatever you use to set up routes) set up all your routes in the correct order (and you'll notice that the routing table (route -nv) does change this order). A workaround is now to delete the mixed up route (I believe it was the network to which your computer is directly connected to - and this one has to be last), and to add it again. Example: /etc/route add ${NETWORK} /etc/route add ${NETWORK2} gw ${GATEWAY2} metric 1 /etc/route add default gw ${GATEWAY} metric 1 /etc/route del ${NETWORK} /etc/route add ${NETWORK} Hope this helps sw/isd -- ======================================================================== | Stefan Weihe weihe@isd.uni-stuttgart.de | | | | Institute for Statics and Dynamics of Aerospace Structures (ISD) | | University of Stuttgart, Pfaffenwaldring 27, D-70550 Stuttgart | | Phone: +49-711-685-2502 Fax: +49-711-685-3706 | ======================================================================== ------------------------------ From: piggy@hilbert.maths.utas.edu.au (La Monte Yarroll) Crossposted-To: comp.os.linux.help Subject: Re: Help with smail problem please!!

Check again and make sure that you are using the BIND router (arpa-something-or-other) and NOT the GETHOSTBYNAME router for SMTP delivery. The machine you are having trouble with has no published A records so GETHOSTBYNAME can not reach it. I've seen this problem with a LOT of smail installations on the Internet, including the default SLS distribution! This comes about in part because the smail installation files generally default to GETHOSTBYNAME rather than BIND. >Thanks in advance, >Darren. >=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= > Darren W.

For a long time, I managed to use /dev/ttyS1 to dial out with my modem. From time to time, the modem did not respond, when opening that port. I now understand, this is due to the behaviour of /dev/ttyS*, that they will "hang" until a carrier detect signal is there from the modem. However: - Most of the time, it did not hang, even when there was no connection. This may be a fault with my internal modem, though. Or it is a problem, that the "carrier detect" is by default "on" after an reset, and the modem has not send an "carrier loss" yet. - I suffer lots of problems with bad connections. Until I switched from /dev/ttyS1 to /dev/cua1, auto retrain did not work. In other words, the line disconnected, when line quality got worse. Now, the modem switches to a lower speed, as you would expect auto-retrain to work. In other words: there are many subtle differences between /dev/cua and /dev/ttyS. I am not experienced with modems, and I do not know much about all the many lines on a serial port, either. But is there someone, who really knows about things, and can write a precise and detailed explanation for the FAQ? Something, that says more than "/dev/cua* are for dial out, and /dev/ttyS* are for dial in". For example: a friend of me suffers badly under both MS-DOS and Linux.

A picture, a 1000 words, all that jazz: Internet <-----> Linux 1 <--->| SLIP | | LAN Linux 2 <--->| The question is how to connect the Linux 2 box to the Internet. Since the only common connection is through Linux 1, then Linux 1 has to be set up as a router. Once this is done then Linux 2 can get to other machines on the Internet. This is a "Good Thing" (TM) and not the waste of resources you describe. > >Might I enquire just exactly what you want to achieve? I cant think of any >earthly use for the scenario you have just outlined.... So I guess all the machines you use are directly connected to the net without a router. This is the exact scenario you need to connect a subnetwork to the Internet. As to the problem, I've done this with Ethernet networks so the principals should be the same: Linux 1 ======= - Enable both the SLIP interface and the eth0 interface. - Set the gateway of the SLIP interface to the internet gateway machine on the other side of the SLIP connection. - Run routed Linux 2 ======= - Enable the eth0 interface - Set the gateway to the IP address of the eth0 interface of Linux 1 routed should bridge packets between the eth0 and SLIP interfaces on Linux 1. The gateway setup of the SLIP interface should route all packets to the Internet gateway machine. The gateway setup of Linux 2 should route all packets to Linux 1.

We started out with SLS 1.03, and have upgraded the kernel to 0.99.13s, libc to 4.4.4, and installed the binaries from the yp-linux package (the lib-source in yp-linux seems to have been folded into libc by now). gcc is 2.4.5. Whoever handles YP for Linux should get in touch with me: there's some bug fixes and a serious change that you *really really really* want! First of all, there are a couple of bug fixes. You should get the new code and merge the changes (which, last I saw, is not going to be easy: whoever made the code in Linux saw fit to change the formatting of most of the files.) There are some important fixes. The change causes the /var/yp/bindings files to be the same as with Sun NIS. This is a good idea for future binary compatibility: if SVR4 binary emulation is added to NetBSD or Linux, we would like those binaries to talk to YP correctly. (Heh. Or SunOS -- that is actually my main concern at the moment -- since NetBSD/amiga can run SunOS sun3 binaries today.) (The Linux and NetBSD YP code should also be compatible, so that if NetBSD ever gets a Linux binary emulation mode that YP still functions..) I've looked at NYS, but it isn't near a finished state. Peter Erikson suggested I replaced yp-linux code (partially) with NYS, but this isn't trivial, so that would be my absolutely last option. I have no idea what NYS is. What is it? Oh and please, a request: The code that I wrote is simply called `YP'. It is not called `NIS' -- as far as I know `NIS' is a copyright/trademark/whatever of Sun. `Yellow Pages' is a trademark of British Telecom, but `YP' is NOT a trademark held by anyone. So call it what I call it -- just plain simple `YP' (YP is not an acronym for anything, except perhaps "Yucky Poo!" ) -- This space not left unintentionally unblank. deraadt@fsa.ca ------------------------------ From: mahesh@inca.gate.net (Mahesh Neelakanta) Subject: Re: backup using floppies Date: 3 Dec 1993 10:17:31 -0500 In article <754831887.AA00000@owl.isis.org> Dr.Andy@p3.f506.n163.z1.fidonet.org (Dr Andy) writes: > # tar cvfzM /dev/fd0 / > Try cpio instead: find / -type f -print |cpio --create --block-size=32 --verbose -O /dev/fd0H1440 will save all files to a 3.5" floppy (Drive A:). mahesh ps.
