I have 2 NE2000 Compatable Network Cards in the Linux system
connecing with two network separately. They are
eth0 10.67.69.69
eth1 192.168.1.1
I can ping both of them in the PC which they are located. I also can
ping the system conneted with eth0. However, I found that I can't ping
the system connect with eth1.
What is the problem? Is that the problem of routing?
Pls help me. Thanks a lot.
Jette.

Hi,
Looks like you should put your ISP domain name instead of yours in
/etc/resolv.conf .
search your_ISP_domain
DNS_number_1
DNS_number_2
Good play,

Linus Torvalds claims to be trying to take over the world.

A couple of thoughts on getting samba to work instead of an alternative,
mainly because it works great when everything is setup correctly...
I didn't see you post your smb.conf, that might help, but here's a couple of
thoughts...
1) First verify that File and Printer sharing is installed on the clients
that can't be seen..
2) Under properties of the above, change value for browse master to disabled
and LM announce to NO.
3) check your smb.conf for the following
local master = yes
preferred master = yes
4) I personnally run the linux server as a wins server also, I'm not sure if
it would help you or not.
wins support = yes
add the ip address of the linux box to properties of TCP/IP under WINS
server
If none of these help, email me directly with your smb.conf and we'll
straighten it out.

Yes. Accessing may be enabled for example either in source ip address
(receptionist pc) or username/password basis. Read more about this ACL
configuration from from Squid docs or website http://squid.nlanr.net/

Set the user's FTP program to Passive mode. Otherwise, FTP likes to open
a bunch of ports, one for each transfer. In Passive mode, as I
understand
it, it stays on the port you chose for it.

Hi.
I've got a static IP through a cable modem, so my Linux PC is
always available. This morning I come down to find my computer
shutdown, and after checking a few logfiles, I found that the system
ran some system cron jobs at 7:01 AM, but then crashed sometime
thereafter, even though I hadnt touched my computer since the
night before.
I was looking in the file /var/log/secure, and found this:
Mar 1 20:26:20 CS373959-A imapd[761]: connect from 206.247.5.16
Mar 1 20:26:20 CS373959-A imapd[761]: error: cannot execute
/usr/sbin/imapd: No such file or directory
Mar 2 00:48:25 CS373959-A imapd[771]: connect from 12.4.126.66
Mar 2 00:48:25 CS373959-A imapd[771]: error: cannot execute
/usr/sbin/imapd: No such file or directory
Mar 3 06:32:35 CS373959-A imapd[4908]: warning: can't get client
address: Connection reset by peer
Mar 3 06:32:35 CS373959-A imapd[4908]: connect from unknown
Mar 3 06:32:35 CS373959-A imapd[4908]: error: cannot execute
/usr/sbin/imapd: No such file or directory
Note that the last entry was approximately 1/2 hour before my
system crashed, and I dont recognize either of those IP's.
Can someone explain to me what is going on here?
What are these guys trying to do? I believe that imapd is a POP
server, which I'm not using, so it seems strange that that could
have crashed the system.
Also, in older /var/log/secure files I've noted several telnets from
unknown IP's too, that look like this:
Mar 1 03:30:53 CS373959-A in.telnetd[647]: connect from 24.65.125.79
Are these just random attempts from people hoping to guess my root
password?
Is there anywhere else to look for intrusions, and what can I do?
Thanks.

I need to be able to limit certain users to access selected sites,

receptionist might only be allowed access to "www.fedex.com", while
developers have general HTTP access. Is it possible to do this under

Hmm... maybe it didnt go out correctly the first time.. here it is
again:..
I was recently doing some reading in the "Cisco Router
Configuration" book by Cisco press (ISBN 1-57870-022-1). In chapter 4,
when configuring dialup ppp interfaces.....
On page 207-208, it states :
"... the IOS software acts as a proxy DHCP client, requesting an IP
address from the DHCP server on behalf of the dialup client. This
configuration method is enabled by specifying the keyword parameter dhcp
to the peer default ip address command. The access server must also be
configured with the IP address of a DHCP server to query for address
requests via the IOS global configuration command ip dhcp-server. The IP
pools defined in the DHCP server would contain addresses from the IP
network address of the access servers's LAN interface..."
Similar info is at
http://www.cisco.com/univercd/cc/td/doc/product/software/ios112/112cg_cr/4cbook/4cppp.htm
My question is: Has anyone used this feature with the ISC DHCP server?
If so, what client identifier do the ciscos give the dhcp server (how
does the dhcp server distinguish each port?) and more important: does
it work?

I was recently doing some reading in the "Cisco Router
Configuration" book by Cisco press (ISBN 1-57870-022-1). In chapter 4,
when configuring dialup ppp interfaces.....
On page 207-208, it states :
"... the IOS software acts as a proxy DHCP client, requesting an IP
address from the DHCP server on behalf of the dialup client. This
configuration method is enabled by specifying the keyword parameter dhcp
to the peer default ip address command. The access server must also be
configured with the IP address of a DHCP server to query for address
requests via the IOS global configuration command ip dhcp-server. The IP
pools defined in the DHCP server would contain addresses from the IP
network address of the access servers's LAN interface..."
Similar info is at
http://www.cisco.com/univercd/cc/td/doc/product/software/ios112/112cg_cr/4cbook/4cppp.htm
My question is: Has anyone used this feature with the ISC DHCP server?
If so, what client identifier do the ciscos give the dhcp server (how
does the dhcp server distinguish each port?) and more important: does
it work?
