I'm trying to establish a connection between two machines, one running pppd
2.3.5 and the other 2.3.7, and regardless of my using "bsdcomp x,x" and
"deflate x,x" options (or both simultaneously), pppstats (and /proc/net/dev)
report that I'm getting zero compression.
I've properly aliased ppp-compress-21,24, and 26, and lsmod reports that
both ppp_deflate and bsd_comp are loaded and used by 1 process... yet
there's not active compression taking place!!!
What am I missing?
Thanks,
Eric

Hi,
Correct me if I'm wrong, but I don't think it can be done.
Swap is not a file system. I haven't tried it recently, but I'm pretty
darn sure that fsck would choke on a swap partition.
And if it's not a file system, NFS can't deal with it.
Gary.

Hi all,
does anybody have hints on how to swap over NFS?
I've a linux client here and a Sun (running Solaris) which provides all
the directories via NFS. All's well exept for swapping! :-(
Any hints on how to export the swapfile from Solaris? Or how to import
(mount) it correctly on the Linux box? Kernel is 2.2.10 ...
At the moemnt, I've the swapfile mounted quite ordinary and loop it, then
I do a mkswap to the loop devce and then issue a swapon to it...
This seems to work, but I get several error messages like:
swapon: Unable to find swap-space signature
ll_rw_block: Trying to read non existent block-device 00:04 (0)
My /etc/fstab looks like this:
server:/fs/rboot/linux-sparc/root / nfs defaults 1 1
server:/fs/rboot/linux-sparc/swap/ /nfsswap nfs defaults,sync 1 1
proc /proc proc defaults 0 0
devpts /dev/pts devpts mode=0622 0 0
server:/fs/rboot/linux-sparc/usr /usr nfs defaults 1 1
And I'm using the following script to set up swapspace:
SWAPFILE="/nfsswap/myclientsswapfile"
echo "Setting up swap over NFS... "
losetup /dev/loop0 $SWAPFILE
mkswap -v1 /dev/loop0
swapon /dev/loop0
mkswap -v1 /dev/loop0
swapon /dev/loop0
echo "done."
I noticed, that I had to create the swapfile TWICE (using mkswap),
otherwise it did only say
/dev/loop0: invalid argument
Can anyone expplain this, PLEASE???
Or can anyone, as said before, give hints on how to swap over NFS?
THANKS!
Andi

Yes, that's correct. You can do ipfwadm -I -l to list all incoming traffic
rules while you test.

Just have a question. I am using a cable modem hooked up to my Linux box
(RH 5.2) and am using ipfwadm to masquerade it to another computer so
both
can share the cable modem, using the following commands:
ipfwadm -F -p deny
ipfwadm -F

If a try to ifconfig eth1 (ifconfig eth1 10.1.1.1 255.0.0.0) I get
SIOCSIFADDR: Operation not supported by device
SIOCSIFADDR: Operation not supported by device
I have tried MULTIPLE types of cards. What I have in the box now is two
PCI
cards one Intel and one 3com.
Both work if they are the ONLY card in the box. If bothare in the box only
one will work (the intel card)
I've also tried it with two 3 com cards (one pci and one isa) if I do this
only the pcicard works.
Also tried it with two isa cards (only one will work)
THanks.
If the cards are pci, then there SHOULD be a utility supplied by your PC vendor
to set the base addresses and irqs for your cards so they don't conflict. I bet
that they do. Unfortunately, some vendors supply pcs without such configuration
tools.
For example, a Dell P133 (I have one... I know) from 95-96 era does not
supply this pci config software. See Donald Becker's Vortex page located
at http://cesdis.gsfc.nasa.gov/linux/ for more about that.. As is suggested
there, you CAN swap the cards around in the pci slots. This should
sort out the addresses and irqs for you (worked for me!).
If you have a 3Com509B ISA card, it can be configured by getting the latest
source from Mr. Becker's site (or from a recent vendor distribution?) and
compile the driver code into the kernel (I couldn't make it go compiling the
driver as
a module ... your mileage may vary). I compiled version 1.16 of 3c509.c (see
comment in top of the source file). You will want to follow the instructions
found
at the cesdis.nasa.gov site for this card to set the addl parameters in your
lilo.conf
file that will allow you to set an irq and base address that the intel card IS
NOT
using (and none of your other cards use either).
Good luck.

I believe you can do this with the squid proxy server.
Will have to have a dedicated machine for that though.
Lee Reynolds wrote in message [EMAIL PROTECTED]...
I have a network in my house with 4 computers attached to it each of
which uses the the linux server as the gateway to the internet through
IP masq. The problem we are having is that sometimes one user's
connection hogs all the bandwidth and leaves nothing for anyone else.
So my question is whether there is a way to limit bandwidth under linux
or more ideally modify that limit based on the number of computers
currently connected. If there is a howto or other documentation about
this, please let me know.
Thanks,

how do i set up dial on demand for my to windoze machines going out the

i dont want twenty four hours a day access.
I use the c-mserver and ipfwadm at the linux end. I intalled tkmasqdial
for the linux boxen and Charles Wright's WNT/95 client on the Win boxen.
For more info see:
http://metalab.unc.edu/mdw/HOWTO/mini/IP-Masquerade.html
http://cpwright.villagenet.com/mserver/
TkMasqdial is available as an RPM at:
http://rufus.w3.org/linux/RPM/index.html
This assumes you have a working ppp dial-up connection...
