Subject: get mail past tcpwrap?
Date: 13 Jan 1999 16:37:15 GMT
Hi. So recently i got hacked (surprise surprise) and so i decided to
close out everyone else except for a few hosts using hosts.allow and
hosts.deny. However, now when i try to send mail to myself from another
(denied) host, the smtp connection gets refused. Is there a line i can
put in either file like, "ALL: in.smtpd", to allow mail in? or is this
a stupid security risk? Thanks,

Date: Fri, 15 Jan 1999 02:15:01 +0000
Hi Folks.
Thanks to anyone replying to this one.
I have RH 5.1 installed on a 2nd machine at work. My problem is that I
find telnet sessions to VMS hosts
get disconnected after say 10mins of terminal inactivity. This is both
with console mode telnet and telnet running in either rxvt / xterm /
nxterm. It appears to be fine connecting to solaris servers which points
to the VMS host as the trouble maker. On the same machine when booted
into M$windows95 i don't have the same problem with reflection (vt420
emulator)
any ideas?
thanks
Dave.

Static on some connections is POSSIBLE but the default is DHCP. I use
static but this is NOT the way they set it up on your WINDOWS or MAC
only boxes. They "will not attempt" an installation on a linux box. My
IP (check it out from both my postings) has not changed in over a
year. So, unless you want them to walk back out the door when they
show up for installation, you'd better have a suitable windows or Mac
box for which to install the nic card on. What you do with it
afterwards, is up to you.
They pass netbios riding on TCP/IP depending on your installation
area's modems, 'Lan City or Motorola' but not Netbui, IPX/SPX or other
NON ROUTABLE protocols. @home strongly recommend turning off file and
print sharing under TCP/IP protocol.

After you compiled the kernel did you do a make modules ; make
modules_install in the /usr/src/linux directory? Do that everytime
you compile the kernel, that command creates your modules that you
specified in you kernel configuration.

Subject: Pop mailer dies
My linux system seems to be having trouble with its POP mailer. The
computer is a P-133, with 64meg RAM, 3gig SCSI disk, and Etherlink III
network card. I set this up a couple of years ago and it worked fine
for the first year or so.
It is in a K-12 school district and some time near the end of the last
school year (May 98) it started refusing POP requests on a regular
basis. We have 450+ computers running Eudora Lite spread out across the
district. Most of these are set to check mail every 5 min. What
happens is Eudora starts getting a "refused connection" error. First
this happened once a week or so. The solution has been, reboot will fix
it. Then this August (start of this school year) it started being an
almost every day around lunch time (more people checking mail at the
same time). Now it happens 2 - 3 times a day.
What I know is, it stops firing in.pop3d. I don't think it is a
sendmail problem, I can still send mail through the SMTP server (even
using Eudora). The server is still accepting e-mail, I can log into
another account and send mail to my account on this server and it will
receive it (Eudora just can not get it). If I telnet into the server
which is not responding for Eudora I can use mailx or pine and send and
receive mail with out any problems. When I check my logs I can see that
during the time we are having problems there are no instances of
in.pop3d.
I feel like I know enough to be dangerous but this is beyond me.
Something must get reset or the reboot would not fix it. Any help is
appreciated.

In the diald source code file is a script called "dctrl". This is
a TCL/TK script. If you have xwindows installed, you can run this
script and see quite a bit of information on diald.
One problem that I had with diald initially was that I had Netscape
checking for email every 10 minutes and I didn't know it. Of course,
diald would just shut down and then Netscape would check for email
and then bring the link back up. This went on for a couple of weeks
before I finally noticed it.
Something else to look into is what other networking protocols might
be installed on the Windows side. I only have TCP/IP and nothing
else. I have seen others post about Netbeui (I think that is the
one) causing problems with bringing the link up.
Also, make sure all the machines on your network are in each others
"hosts" file. Even Windows can have one. Mine is in the /windows
directory.
I also don't run any sort of DNS on my system. Are you bringing yours
up when you start your connection or is it running all of the time?
I would think if it runs all of the time, then everytime a lookup
occurs, your link will come up.

If you can ping your ISP, then that sounds good. If you can't ping
anything past them, then I guess you need to look at your /etc/resolv.conf
file. You might also need to modify your /etc/host.conf file.
I believe the host.conf file tells your machine where to look and in
what order to find machine addresses.
Mine has the following:
###/etc/host.conf###
order hosts bind
multi on
nospoof on
You also mention something about not having a defaultroute. I'm using
diald and have commented out everything in my /etc/ppp/options file
but I did look in my /etc/diald.conf file and did see that I have
the defaultroute command there. Whether this is important for you,
I can't answer.
It's also possible there may be a problem with your network configuration
but that's for another day. :)

What is in your /etc/ppp/options file. Looking through the man
page for pppd talks about the "-detach" option. I believe this
keeps pppd from becoming a background process or something
similar.
Just a thought.

If you haven't already, try replacing your pop demon with qpopper
from the Eudora people. I'm assuming your problem is the same as
many other people have been having. There is a lock file that is
not getting deleted after the mail is checked. Take a look in
/var/tmp/.pop and see if there are any lock files hanging around.
Since I replaced my pop demon at home with the qpopper demon, I have
not had this problem since. This is on a Slackware system.

I would like to find a good networking book for Linux. Something that

Since you don't provide any useable information about your present setup,
probably nobody will be able to solve it. Please come back with some
more input, especially the output of "dmesg" "ifconfig" and "route -n".

curious i tried to telnet to unix machine on the network, but no error, it

maybe dhcpcd is just not recording information from the server? dont know,
