Subject: Re: Linux IRQ oops
You can also check in the file /proc/interrupts
There you will find the interrupt settings for your various devices,
the first column being the interrupt number and the last column being
the device.

Subject: socket in CLOSE state ?!?
Date: Tue, 20 Jul 1999 09:30:36 GMT
Hi there !
i can't figure out what CLOSE state for a socket means (not CLOSE_WAIT
nor CLOSED) when i perform a netstat -a.
i've found no documentation about it. i'm using a linux box (kernel
2.2.9).
the point is that i'm afraid there is no time out for that state !
thankyou for your help !

Subject: Firewall forwarding NetBios?
Date: Tue, 20 Jul 1999 11:50:11 +0100
Hi all,
I�ve got a Problem with my Linux-Firewall. I am in a large Domain with
my NT-maschine behind a Linux Firwall.
NT-Comp----------------Linux-Firewall--------------Domain------------gateway
129.168.12.78 abc.cdf.bla.251
abc.cdf.bla.xxx abc.cdf.bla.254
The firewall works with ipfwadm and masquerading. I want to access the
other computers of the domain via SMB, but this does not work. I
noticed that my NT-workstation sends the UDP packets concerning NetBIOS
(Port 137-119) to the Broadcast address of its net. But they are not
masqueraded and routed though I have all TCP and UDP Ports open.
Thanks for any help

With regard to Windows passwords. My current understanding is that windoze
95 original does not use encryped passwords. However 95 B/C and 98 do. Set
the use encrypted passwords option in SAMBA to yes and it will work just
fine.

Hi Jeff
You have my undying gratitude :-) I followed your advice and found
that these two daemons were not installed on the systems at all, so
after finding the right package and installing them it solved the

I have managed to mount from the laptop without any problem, but from
the desktop machine, when I try to mount the remote file system I get
the following message:-
mount: wrong fs type, bad option, bad superblock on Pico:/home/peter
or too many mounted file systems.
I have checked most things I can think of, but no luck. Any ideas ?
I have been struggling with Linux now for 4 weeks and am making very
slow progress but am too stubborn to give in (grin), I can see good
things in the future.

first, set up a user that is identical on both sides ( add your 'root'
user to win-boxes, or 'ben williams' to linux.
have the same password on both sides.
this makes it easier .
next, win98 and nt /sp3 have encrypted passwords, so you will have to
'enableplaintextpassword' in the registry ( somewhere under
services/rdr/parameters), you can find in a lot of winnt-howtos.
or, you set up samba with encrypted passwords - there is a howto for
that but i have not done it yet.
last, make the share accessible for the identical user.
in samba2.0 or higher, there is a pretty good diagnosis.txt - step by
step troubleshooter, plus the swat - admin-tool.
i find them helpfull.

Subject: maximum size of NIS maps?
Date: Tue, 20 Jul 1999 12:43:29 +0000
I need to create an NIS group map that will have over 1000 users in 1
group but it seems that the makedbm program I have is unable to do this.
>From the man page, it says that it separates the key from the data by a
space of tab character, but the group file uses neither of these and so
I figure it is trying to put the entire line into the key. This would be
over 7500 characters which perhaps is a bit to much for a key in a GDBM
table.
Is there anyway around this or am I just totally off base with this and
missing something simple?
Thanks for any suggestions,
Brian

Subject: Ethertap again.
Date: 20 Jul 1999 11:31:08 GMT
Hello people,
I have now successfully configured ethertap on two PCs, I can ping
to
tap0 from either box, and the sniffer program sees the icmp requests
and replies as
well. But when I write to tap0, it never comes down to
the physical wire as the
sniffer doesn't get any scent of it. Now I want to
know whether I can force packets
sent to tap0 to be forwarded to eth0.
Can this be done by modifying ethertap.c and
recompiling it.
I thought since ethertap is using netlink, packets should be sent on
the
wire. But I am just a fresh graduate,and I may be grossly mistaken. Is
there any
other way of going about it?
My real aim is to talk between two ethernet cards without
using TCP/IP.
Thanks All,

The most beatiful approach, in my opinion, is to use what the standard
library uses, which is predicates. The approach is just slightly
different from your last one:
template <class T> struct less : public binary_function<T, T, bool> {
bool operator() (const T& x, const T& y) const {return x<y; }
};
template <class T>
inline const T& min(T const& a, T const& b) {
less comp;
return comp(a, b) ? a : b;
}
Now we specialize less for our class Strange
template<> struct less : public binary_function<Strange, Strange, bool>
{
bool operator() (const Strange& x, const Strange& y) const {return
x.strangeLessThan( y ); }
};
Which would look like:
main
{
Strange x;
Strange y;
Strange m = min(x,y);
int a, b;
int c = min(a,b)
...
}
The application programmer will only have to worry about specializing
less for the Strange class, nothing else. The main code is simple,
elegant, no extra run-time costs!
