Since this works fine on my SUN, I am assuming that this is linux specific.
|
|
Anyone know why my .bashrc does not run when I login??? I thought that if
|
|
you had a .bashrc in your $HOME directory, it would get executed? What file
|
|
is supposed to look to see if there is a .bashrc to run???
|
|
|
|
And my alaises are not enabled either. Where does the system get these defaults
|
|
from? There isn't a HOW-TO describing this is there???
|
|
|

Thanks...

I don't think you need a patch to compile correctly. I compiled mine on
|

1.1.35 kernel. I got a few warnings but that's OK. All i did was to modify

the pathnames.h and run build lnx.

A lot of things have changed in recent kernel releases. I'm currently
|
|
running v1.1.37 with QUOTA and ACCT patches, but it won't patch up to
|
|
v1.1.49 cleanly. Usually I'd just go in and apply the patches by hand
|
|
but this time it doesn't look as easy as it normally does.
|
|
|
|
Anyone know if QUOTA/ACCT will be available for the 1.1.49 (or is it
|
|
1.1.50 now?) in the near future? I ask now mostly because of the Linux
|
|
code freeze for 1.2.0 being in affect.
|

Thanks for any help.

Something weird is going on here. I jumped from 1.0.9 to 1.1.45 wtihout
|
|
any problems. I applied the APM and QLogic SCSI patches to try out.
|
|
(I don't think these are the problem, but read on...) I also applied the
|
|
.46->.49 patches. I recompiled the kernel, installed it and rebooted.
|
|
I went to recompile the kernel again and noticed after about an hour it
|
|
was only on irq.c. It was massively swapping. I started up top and
|
|
watched it for a bit and noticed something really nasty. Top said
|
|
that I had 1500K of memory available. I actually have 4 meg.
|
|
I stopped the build of kernel. I deinstalled the .49 kernel
|
|
and re-installed the .45 kernel (with the APM and QLogic patches).
|
|
After rebooting, the kernel (and top) report that I have 3112K free to
|
|
use. So there appears to be something wrong between .46 and .49
|
|
that has changed the way the kernel is recognizing memory.
|
|
I'm going to apply each patch level individually and see if I can
|
|
spot at which level it breaks.
|
|
|
|
Hope this helps,

You don't say what news software you're using, but for INN it's handled

by the moderators file. The default contents should work. If

I apologize. I am the author of the /bin/login replacement that is included

is not to blame. I had asked him not to distribute my (ugly) source. :-)

|
|
|
|
This is not necessary. The source for the binary in question will be
|
|
posted later this evening. I need to return to my linux box in order
|
|
to upload it. I do not have it readily available at the moment.
|
|
|
|
>I have received an email from someone who also noticed the
|
|

|
|
>provided.
|
|
|
|
I will post the source to the /bin/login replacement that I wrote, and trust
|
|
on my own system. I did not realize that the net would grow so suspicious.
|
|
I should have known better. :-) After all, it could be snake oil, for
|
|
all the net knows. I realize now, especially after reading the files
|
|
focusing on security issues that were included with PGP, that it is *very*
|
|
important to make the source available to public scrutiny. Indeed, for
|
|
similar reasons, I do not trust Clipper encryption (aside from the gov't
|
|
back-door).
|
|
|
|
I will also post the version of GCC with which is was compiled, the version
|
|
of libc with which it was compiled, and the compilation flags, so that
|
|
each person make verify that it is indeed the source from which that
|
|
binary was created. I will also have Mohan Kokal include the source in
|
|
future versions of the shadow-mk package.
|
|
|
|
In the meantime, I will detail how my patch works, and how it closes the
|
|
now well known hole:
|
|
|
|
My patch simply forces all argv[] elements beginning with a - to be no
|
|
longer than 2 characters long, by writing a 0 into the third position
|
|
after the dash. Thus, if a user tries login -froot, the "r" in root
|
|
would be overwritten, and the remainder, "oot", would be affectively
|
|
truncated.
|
|
|
|
Furthermore, my patch addresses another security issue, the misuse of
|
|
the semi-documented -h switch, by disallowing anyone with a real uid greater
|
|
than 100 from using it.
|
|
|
|
Once all paramters have been patched, and the absence of -h is assured if
|
|
UID>100, all parameters are passed to an unmodified /bin/_login.
|
|
|
|
Again, as I said, the source will be posted later this evening, along with
|
|
GCC version, libc version, optimization flags, and so on.

To whom are you referring? Mohan Kokal may have a number of accounts on
|
|
various Linux boxes, for various reasons. If you are referring to one
|
|
of these accounts, please make known the people involved, as well as
|
|
circumstances in greater detail than you have. This is an accusatory
|
|
statement based on heresay and circumstantial evidence.
|
|
|
|
Furthermore, "bragging about violating computer security" may be something
|
|
as simple as "whoa... on an older Linux box, I noticed a hole in crontab
|
|
that allowed such and such..." or "yeah, I used rlogin to gain root--that
|
|
old /bin/login was a joke."
|
|
|
|
I, as well as some others, I am certain, would like to see a factual basis
|
|
for this outright character assassination that you are making. I have no
|
|
reason to doubt that you may be able to support your statements. However,
|
|
I also have NO reason whatsoever to believe any of your closing statements.

Hi!
|
|
|
|
From what I recall, the numbers you listed are the speeds of the
|
|
serial port itself. The seed of the modem is set using the
|
|
initialization string that you send to it and don't have to be the
|
|
same. Use the 19200 baud speed for your serial port. That way the
|
|
serial port sends to the modem at 19200 baud, the modem then
|
|
compresses and sends the data over the phone lines at 14400.

Agree. I have a STB Powergraph X-24 ISA. It's a very nice card.
|
|
Very fast for this price ($125 at Treasure Chest).
|

|
|
BTW, I do have some funny problems on the clock-synthesizer. It takes
|
|
about 5 second to set the clock, no matter when I start the X, or when
|
|
I switch the mode. It works fine, just takes some time. Someone
|
|
suggests that it might be my monitor problem, 'cause I have a cheap
|
|
no-name monitor (Korean made SVGA NI). Is it the problem you're
|
|
talking about on the synthesizer of recent boards?
|
|
|
|
Thanks.

You'd think it was the end of the world... have you considered that
|

perhaps your Sun and your Linux machines have different versions of
|
|
Bash or that your Sun and your Linux machines' copies of Bash were
|
|
compiled with different options?

|

May I recommend typing:
|
|
|
|
$ man bash
|
|
|
|
or
|
|
|
|
$ info bash
|
|
|
|
It works 9 out of 10 times for answering questions about Bash.
|
|
|
|
Until then, create a file called .bash_profile and put the following
|
|
text into it.
|
|
|
|
======= start of cut text =======
|
|
source ~/.bashrc
|
|
======= end =======

I apologize. I am the author of the /bin/login replacement that is included

in the shadow-mk package. Mohan Kokal, the author of the shadow-mk package,
|
|
is not to blame. I had asked him not to distribute my (ugly) source. :-)

|
|
|
|
This is not necessary. The source for the binary in question will be
|
|
posted later this evening. I need to return to my linux box in order
|
|
to upload it. I do not have it readily available at the moment.
|
|
|
|
>I have received an email from someone who also noticed the
|
|

|
|
>provided.
|
|
|
|
I will post the source to the /bin/login replacement that I wrote, and trust
|
|
on my own system. I did not realize that the net would grow so suspicious.
|
|
I should have known better. :-) After all, it could be snake oil, for
|
|
all the net knows. I realize now, especially after reading the files
|
|
focusing on security issues that were included with PGP, that it is *very*
|
|
important to make the source available to public scrutiny. Indeed, for
|
|
similar reasons, I do not trust Clipper encryption (aside from the gov't
|
|
back-door).
|
|
|
|
I will also post the version of GCC with which is was compiled, the version
|
|
of libc with which it was compiled, and the compilation flags, so that
|
|
each person make verify that it is indeed the source from which that
|
|
binary was created. I will also have Mohan Kokal include the source in
|
|
future versions of the shadow-mk package.
|
|
|
|
In the meantime, I will detail how my patch works, and how it closes the
|
|
now well known hole:
|
|
|
|
My patch simply forces all argv[] elements beginning with a - to be no
|
|
longer than 2 characters long, by writing a 0 into the third position
|
|
after the dash. Thus, if a user tries login -froot, the "r" in root
|
|
would be overwritten, and the remainder, "oot", would be affectively
|
|
truncated.
|
|
|
|
Furthermore, my patch addresses another security issue, the misuse of
|
|
the semi-documented -h switch, by disallowing anyone with a real uid greater
|
|
than 100 from using it.
|
|
|
|
Once all paramters have been patched, and the absence of -h is assured if
|
|
UID>100, all parameters are passed to an unmodified /bin/_login.
|
|
|
|
The new /bin/login is statically linked, using maximum optimizations,
|
|
and is stripped, to make the smallest possible binary.
|
|
|
|
Again, as I said, the source will be posted later this evening, along with
|
|
GCC version, libc version, optimization flags, and so on.

To whom are you referring? Mohan Kokal may have a number of accounts on
|
|
various Linux boxes, for various reasons. If you are referring to one
|
|
of these accounts, please make known the circumstances in greater detail
|
|
than you have. This is an accusatory statement based on heresay and
|
|
circumstantial evidence.
|
|
|
|
Furthermore, "bragging about violating computer security" may be something
|
|
as simple as "whoa... on an older Linux box, I noticed a hole in crontab
|
|
that allowed such and such..." or "yeah, I used rlogin to gain root--that
|
|
old /bin/login was a joke."
|
|
|
|
I, as well as some others, I am certain, would like to see a factual basis
|
|
for this outright character assassination that you are making. I have no
|
|
reason to doubt that you may be able to support your statements. However,
|
|
I also have NO reason whatsoever to believe any of your closing statements.

It's probably not going to work unless you've installed the "mh"
