I think you want somthing like this:
chmod 766 file (or dir)
The attributes are sorted like this
bit (dec. value) meaning
2 4 R(ead)
1 2 W(rite)
0 1 X(ecute)
the file attributes ar in the following order
owner user world
- - -
so the above chmod command would do
rwx for the owner
rw- for the users
rw- for the world
I hope you can do somthing with this!

Subject: ppp-dialin trouble
Crossposted-To: linux.dev.ppp
Hello,
Ive got the following problem while trying to set up an ppp-server.
(I'm using SuSE-Linux 6.0 and connected an external ISDN-Adapter.=20
Ppp-dialout to my ISP works fine.)
I set up mgetty and my isdn-adapter reacts on incoming calls=20
correctly. Authentication with chap is functioning (so says the=20
logfile), but after the authentication the following error occurs:
pppd[839]: write: warning: Input/output error(5)=20
pppd[839]: ioctl(PPPIOCSASYNCMAP): Input/output error(5)
pppd[839]: Exit.
=20
Does anyone have a hint/solution for me ?
Thanks a lot.
Bodo

Ref: "chmod" command.
A week or so ago I was having difficulty in changing a file
permission "/etc/rc.d/rc.local"...never got my chmod command
to work...however, a guru friend of mine gave me a universal
command that made every file basically a R-W file. He has
since gone on an extended vacation. I need help!
I have been trying to use a simple chmod command to make just
a couple of files permit me to write also. I have since set the files
back to the original status...(not so dangerous as before)...
Now, my question is...could someone send me the exact,
workable chmod command to enable write on a file?
I keep getting "chmod" errors...mode format, etc...I have
tried every possible combo as per examples...but, to no
avail. Is there some universal command to enable "chmod"
on some distributions?
I am in the "root" command function as I should be...but,
apparently I do not have the "chmod" format exactly
right...again would someone send me a note with a
chmod command that works...gramatically and perfect?
I seem to be having some problem with it.
Many thanks,
Leonard...

Just a hint:
usually the Windoze Boxes should use broadcasting to find themself and the
server. Using MS DHCP I can supply something called "NetBIOS Node Type"
where I can supply Information which Nameservice to use and in which order
(BCast / WINS). I can also assign a WINS Server via DHCP to the clients, if
I have one setup on my network. Don't know, if this is RFC-conformant, but
it works...:-(

Certain dynamic IP name resolving services will let you update the IP addy
by email or some such, so that could work. In addition, he could simply
have his PPP login script mail him the IP addy after he gets connected.

Hi,
I will like to make my home machine (DHCP on cable modem) be register on

My guess will be to write two scripts my home sending it's IP true a

But, I sure there is already a package doing that .. but I just don't

There are two issues here. One is the firewalling of the ADSL line. Some ISPs
firewall them so you don't have to worry about Windows Boxen being blown up by
unfriendly. This is a service they provide for free, you may want to check to
see if they are blocking ftp port.
Secondly, you have to have ftp service installed. if you cannot ftp to your
own loopback address, then it isn't installed and running. Find your install
CD, and install the wu-ftpxxxxx.rpm package with the rpm command. Short
version:
rpm --install /mnt/cdrom/RedHat/RPMS/wu-ftp*.rpm
if you want anonymous logins, install the ftp-anon package as well.
You shouldn't need to restart, as soon as they are installed, it should be up
and running.

Ok. What i reached after all by myself may be called a giant succes!!
There is just one thing: My two clients cannot be reached or seen by the
server (SuSE 6.1)
Everything is well connected as far as I can see.
The server is a pentium 100 mhz.
Connected through a hub are 2 Windows 95 workstations with
TCP/IP;netbeui.
Samba is installed and the adapters are all working without conflicts or
so. The domain name is the same as the working group on the 2 p.c.'s
Though, I cannot ping.
What might be the trouble here?
do you have an idea hot to fix this? Please help me out! I will include
you in my prayers.

I have the feeling you're going through the same thing I did when a coworker
here tried to use proxy 2 and netscape.
I did some research on the Netscape page, and lo and behold, they have an
article that says basically that NT and Netscape will not get along - NT
refuses to authenticate. They say nothing about a solution, just that the
problem exists.
When using Netscape on a windows client, it does exactly the same thing you
describe.

I found that I need both squid and ipchains, squid handles http, ftp
and ipchains handles everything else
Explore and Netscape worked on my network machines with only squid in place.
I needed iipchains for the email clients to work.
the rules that I found work for me ( but may not be most secure)
ipchains -A forward -s 192.168.1.0/24 -d 192.168.1.0/24
note: no target !
ipchains -A forward -s 192.168.1.0/24 -d 127.0.0.1/24 -j ALLOW
ipchains -A forward -s 192.168.1.0/24 -d !192.168.1.0/24 -j MASQ
The first rule is an accounting rule for me to monitor my own network
The second rule allows my network talk to the localhost.
The third rule says to masqerade any machine on my network communicating
outside of my net. I am counting on 192.168.X.X traffic to not come from the
net.

If your internal network is private, (eg 192.168.1.X), your gateway wont
route packets out of it.
use ipchains to set up masquarading
make sure proxy_arp and forwarding are enabled.

Sounds like a time to live problem!
DNS changes take a while to propagate from Master to Slave DNS's
What you should have done was set the ttl on the resource record in the
DNS to a very low number before making the change, so that slaves update
more frequently. Then change, and changes will propagate faster.
Don't worry, It should fix itself with time.

The REDIRECT option of ipchains is for redirecting to the local machine so
your syntax wont work. Instead you should use a port forwarder to redirect
to another IP address.
You need to build one of the following modules:
ip_masq_portfw
ip_masq_autofw
ip_masq_mfw
I suggest using mfw which works very well (I'm using it).
You need to do a make config on your kernel and then select the option
CONFIG_IP_MASQUERADE_MFW (its in the network options section). Select m for
module and do a make modules and make modules_install and depmod. I use the
/etc/modules file to add the ip_masq_mfw module. Read the kernel
documentation and howtos for help on building the kernel and using and
installing modules. If you haven't built your own kernel for this
installation you will need to actually install the kernel as well (so that
the modules that are built are compatible with your running kernel) using
make zImage or whatever (before make modules). Or maybe try and get the
modules some other way (maybe they're already part of your distribution?)
You'll also need the ipmasqadm utility (don't have a URL for you with me but
have a look on www.freshmeat.net - it might be there). Now use:
ipchains -A input -p TCP -s 1.1.1.1 -d 1.1.1.2 9999 -m 1 -j ACCEPT
This will cause the kernel to mark all packets that match with the value 1.
Now use ipmasqadm like so:
ipmasqadm mfw -A -m 1 -r 192.168.1.2 9999
This will redirect all packets marked with value 1 to the 192.168.1.2.
Good luck.
