Subject: pppd to isp
Date: Tue, 02 Mar 1999 22:29:33 -0600
I have this strange problem while trying to connect to my isp with my
linux box.
chat seems to get the connection live properly however when pppd sends
the lcp,
the server doesn't respond... (im sending this from a win95 machine,
fyi) Unfortunately,
I don't have another isp to try to connect to and the admin at my isp
only knows winnt
so won't support linux connectivity.
I've considered using my win95 box as a proxy but i'd much rather be
free of any
sort of ms dependencies... Any suggestions? Regards,
Ragnar

Would you care to drop the '-detach' and the '&'? They simply cancel
each other out. Who is prepetuating this '-detach ...&' nonsense?

RH defaults to ip forwarding disabled.
To enable do:
echo 1 >/proc/sys/net/ipv4/ip_forward
Then figure out where in the RH setups you change the boot up
default. (I've never used RH so I don't know).

The Linux FreeS/WAN implementation of IPSec exists and is interoperable
with several commercial IPSec VPN servers.
There is a Linux PPTP client and server, and there have been two patches to
PPPD to implement Microsoft-compatible encryption and compression.
And Linux can act as a masquerading gateway if you've already got a PPTP or
IPSec client that you want to use without hogging your phone
line/ISDN/DSL/Cable modem.

That is only true if you have a Boot ROM installed. The vast
majority of 3C590 cards does not have a Boot ROM.
The little 8-pin EEPROM contains no microprocessor code.
All it contains are the settings you can adjust with the
diagnostic programs. 3Com ships a Microsoft diagnostic with the
card, or you can download it from their Web site. Dr. Becker
wrote a Linux diagnostic, available from the NASA Linux site.
One of the bits in the 8-pin EEPROM is *ADVISORY* to the driver,
and tells the driver whether you requested the driver to do automatic
media selection. This bit does not control any hardware function
by itself.
There is enough information in the Linux driver to modify it to
ignore the advisory autodetect bit, in the event you don't want to
use the diagnostic or a LILO command line option.

If there is no terminator, the driver will see continuous collisions
on the 10Base-2 (coax, BNC) port. If the driver is autoselecting, it will
conclude you are not using 10Base-2. If auto select is off and 10Base-2
is selected and there is no terminator, the driver will think the network
is broken.

hello all.
I recently changed to slakware, and since then i have been having
problems with telnet and ftp acess to my own machine (and now logging in
locally too).
When it happened on the first time i just did a reinstall (I had not
installed much stuff onto it since then)...
but now i have everything sorted (or at least i did have everything
sorted until this happened.. ) i would rather work out what the problem
is.
Anyway enough rambling.
The problem itself.
when i try and telnet to my own machine it tells me :
Trying 144.124.229.2...
Connected to pcheac.trf.aber.ac.uk.
Escape character is '^]'.
Welcome to Linux 2.0.36.
pcheac login: dof

Connection closed by foreign host.
When earleir on in the day i was able to.
I can log in as ROOT, but clearly this is not very helpful.
earlier on (the first time i tried loggin in after my pc kicked me off),
it told me /bin/bash execute permission denied, but i looked at the
permissions on /bin/bash and i could see nothing wrong with them.
-rwxr-xr-x 1 root bin 279352 Mar 31 1997 /bin/bash
I cannot also log in locally as non-root.
I added a new user, ("tester" and i was unable to log in with that
either)
Heres an entry from /var/log/messages :

Date: Tue, 02 Mar 1999 20:24:16 GMT
If you're using IP Masqing this solution will do it. Works for me fine.
Specify this when you boot up:
ipautofw -A -r tcp aaaa bbbb -h xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx being
your NT machine running ICQ. aaaa being a port 11-12 numbers away from bbbb.
For example mine looks like this.
ipautofw -A -r tcp 2000 2011 -h 192.168.1.2
Then in ICQ go into Preferences->Connection. Select using a firewall or
proxy. Open the Settings, say you don't have a SOCKS proxy. Then in the "Use
the following TCP ports" put the port aaaa and port bbbb. Whatever numbers
you choose. And your all set. Just need to restart ICQ and possibly your
Linux box if you didn't also run that line at the command line.

Subject: kppp finally works!!
Date: Tue, 02 Mar 1999 20:27:43 GMT
I finally got kppp to dial and connect to my ISP. Previously
it would just connect send my passwords, ID etc, initiate PPP on the
server side and just sit there and time out. I don't know what I did
to make it work but I added this to my /etc/ppp/options file.
-detach
modem
#lock
crtscts
defaultroute
asyncmap 0
mtu 552
mru 552
name expressnet.com
After adding this it worked. If you're having the same symptoms as I
am, give it a try. I just edited this file and nothing else.
It's always the little things that don't work. Heck, I was pulling my
hair out for the last week or 2. My next task is getting my gravis
Xterminator and my WinTV to work in Linux. Any tips?

In related news, I'd like to know if there is any lpd replacement with some
access control. In some places it doesn't make sense to allow every user to
print just because there happens to be a printer there, but the
administrator might want to print something once in a while, so having lpd
running is convenient. If lpr would do a getuid() and compare against a list
of allowed users (kinda like /etc/minicom.users, only for lpr), that would be
ideal.
Has anyone done this yet?

Strange thing is you can't just do that. You need to reboot the WHOLE network to

Hallelujah. I'll take every resource I can get. I think I've nearly got voting
stock in O'Reilly & Associates by now. I installed my first Linux system this
past weekend, and Hardware is great, but Unix experience is nil. I have the
Linux System administrators Guide, and Running Linux, though I thought they both
assumed a lot of basic unix command line knowlege, and I really need something
in hard copy, so I can read it when I CAN'T get the system to do what I want it
to do, like get out of vi, or change my rez in X, how to shut down properly,
etc... I literally rebooted and re-installed 3 times this weekend, because of
little things like not knowing how to escape out of vi or som man page I'd gone
to, and for once, I;d really like to have hard copy docs that were up too date,
so I could read them even when the system is down. I did run across an old copy
of "Linux Unleashed" published by Sams, and while it included an outdated copy
of slackware 2.2, it really does take one by the hand at start and tell them ALL
the keystrokes to gain their independence. I sure they print an updated
edition, just like I hopw there is an updated revision of running Linux, and the
admin guide, as I need to get up to speed on DHCP, and networking in a hurry,
but neither of those books even lists it in the index.

Subject: PPP can't use ISP's Name Server
Date: Wed, 03 Mar 1999 04:43:11 GMT
OK, I'm a newbie... although it has taken me about 4 installs, and a
couple hundred boots to get this far.
I finally can get connected to my ISP (via Minicom), and I start PPP
with: pppd -d /dev/cua1 38400 defaultroute
I can ping across my peer-to-peer lan, which uses the eth0 network
card. When I ping to an internet address... I get no response (all
lost packets).
If I load Netscape, I can access an internet site with the IP address,
but not the www.xxxx.com name. Oddly enough the site responds to
Netscape although not to ping (perhaps that is normal).
Using route -n, I see the four entries expected... and the ppp0 route
has picked up the ISP provided IP address. [I'm using the networking
info at http://rlz.ne.mediaone.net/usr/doc/LDP/install-guide/ ]. There
the example output shows:
Destination
default
and mine shows
Destination
0.0.0.0
Any help would be truly appreciated.
Regards, Mike
PS - I seem forced to use Minicom because my ISP is Netcom.... and my
login starts with #... which isn't a cool character in Linux'ville.
I'm sure there is some sort of escape character... just haven't found
it yet.
