Hi all,
Please help if you know the solution to this problem.
I am trying to set the dummy interface on RedHat 5.1:
ifconfig dummy 192.1.1.13
I get the Error:
SIOCSIFADDR: Operation not supported by device.
I know that the dummy module is in the kernal. in fact after executing the
above command the dummy interface is loaded, I can see it using "lsmod"
command.
What is happening ?

ppp0 is a network device. ppp-off assumes there is a connection on
ppp0 unless you tell it otherwise. If you run /sbin/ifconfig, you
will see all your active connections. I'm not sure why, but sometimes
when dialing in to my ISP, it connects on ppp1, so I then have to use
'ppp-off ppp1' to disconnnect.
Hope this helps.

What it comes down to is that there should be a default location for
the perl binary excatly because to the many perl scripts which has this
location hard coded in the first line. The discussion of whether the
perl program came with the system or is installed later is not relevant
for this standardisation. The perl executable must be installed where
the scripts expects to find it.
You have a similar situation with sendmail. The traditional location is
/usr/lib/sendmail, and a lot of programs depend on that. Now, sendmail is
an executable, so it belongs in one of the bin directories, and as it is
not meant for normal users it is put in /usr/sbin. But for compatibility
reasons there is a symbolic link /usr/lib/sendmail -> /usr/sbin/sendmail.

Subject: Initial Delay in telnet/ftp prompts through ethernet
Date: Mon, 15 Mar 1999 17:45:38 +0900
My Linux machine seems to work quite well for me including masquarading,
etc. But when I tried to get into the machine through ethernet with ftp or
telnet, I get "Connected to ..." message immediately but had to wait a
minute so until I get the first response from the machine. Afterward, it is
very responsive.
This problem happened to me in more than one cases. Has any one experienced
a similar problem? There is no such problem if I access the machine
through modem/ppp, so I suspect this has something to do with my ethernet
setup (netgear /w ne2000 driver).
Any help would be appreciated.

Hi all,
I've got a strange problem with netatalk (last release) and
MacOS 8.5.1...
When trying to copy a somewhat nested folder, the Mac first
says 'Preparing to copy..' but after a short while it tells
me that the operation cannot be performed because the source
can't be found !
When trying to copy just a single folder containing no others
all works fine, a level higher and I get this strange error..
User/Group rights seem to be ok, even playing around with
some of netatalk options doesn't work, there are no messages
in the syslog, too.
Any ideas ??

Date: Mon, 15 Mar 1999 10:00:41 +0100
Hi there, I have just introduced Linux as the most stable, friendly,
inexpensive OS in the world in our organisation and am allowed to test
it. We have installed a popserver and samba server on it, RedHat 5.2
Linux and Imap mailserver. Now we have a strange problem. Every morning
about 9.15 hours some users (all win 95 clients) get a message stating
that they could not connect to de mailserver, check everything and if it
continues contact your system administrator, ergo me. Ten minutes later
the problem dissapears. When I look in the maillog there are a lot of
messages stating AUTHENTICATE twinkie failure. Does anyone has any idea
what is going on? I got an advice to get pop out of inetd and let it run
all the time (how?) instead of letting it start at every request. But if
that is the case, why does it work fine the rest of the day? Oh yeah,
between 8.30 and 9.00 everybody logs on, total 125 clients, which must
be a laugh for linux isn't it?

Hi!
Thanks to all for your help in setting SSH up. All my Linux machines are
happily configured and talking to one another with a clear conscience. Now,
the ugly part of the business: I must have the SSH client for Winblows.
I downloaded and installed F-Secure SSH but somehow I can't talk to any of my
Linux boxes. Does anyone have any idea why this might be? I'm using password
authentication, no compression, port 22. No RSA identity, though I've defined
one.
Is there a good tutorial anywhere on-line?

Nevermind. I figured it out based on a post in comp.os.linux.help.
The short answer, for those interested, is:
1) set ppp0 (or whatever your interface is) so that it may be enabled by
users.
2) run the following from the command line: /usr/sbin/usernetctl ppp0 up
3) when finished run /usr/sbin/usernetctl ppp0 down
This works great for me.

Just another note. These messages are the same as those generated by

I think you will need a second network card - one to plug the cable
modem into and the other to network to the other copmputers.
That is the way I have our cable modem set up with masquerading, and it
works great.

Most likely you don't have any nfs server installed and configured.
The portmap service is also required, as this is the service that will
register all the nfs services (listening on port 111).

I'm looking to set up a small wireless network consisting of a linux box
and a couple of Macs (no Windoze machines). Most of the existing products
I've seen are Win95/98 specific (i.e. HomeFree, Symphony) but I did run
across Proxim's RangeLan2 Ethernet Adapter. All the machines I'm looking
to hookup already have ethernet installed and are split between 2 separate
hubs. I basically want to bridge the hubs (which are on different floors)
without laying cable. From what I can tell from Proxim's literature I
should be able to connect each hub to a 7920 Ethernet Adapter and have a
transparent, wireless bridge between the hubs. Does anyone have any
experience with these adapters. Is it really this simple or are there any
hidden "gotcha's"??

Im new to linux, using redhat 5.2 2.0.36 with samba 1.9.18p10
I have the network working good, just 1 win98 system networked to 1 redhat
linux system. I have just one user account (besides root) on the linux. This
user account directory on linux was accessable in network neighborhood
before I tried to configure encrypted passwords. I tried to set up the
encrypted passwords,
I uncommented, in smb.conf, the
encrypt passwords = yes
smb passwd file = /etc/smbpasswd
then I did
cat passwd | mksmbpasswd.sh >smbpasswd
this created a smbpasswd file but now the user account password doesnt work
when I try to access the user home directory from win 98, it seems the
smbpasswd file made a different password than the user account password. The
password I used was a simple 2 character password. Is that to small for
samba or not a 'legal' password? Anybody know where I went wrong or how I
can reset my password? I can still log into my user account with the
password from the bash shell, but I cant access my user directory in network
neighborhood because it ask for the password and the user account password
doesnt work. I can access the shares on the win 98 system from linux, I have
a printer and a shared directory with full read and write permissions that
has a password on the win 98 that I can access from the linux system . Also
while logged in as the user and using smbpasswd to set the password gets me
nowhere as it ask for my password and the user account password doesnt work.

Actually that is the computr to modem speed. It should be high to
account for the modem to modem compression (at 50K modem to modem speed
that can easily give your 100K needed in computer to modem speed.)
