[SLUG] SSH idle timeouts

[Matt Hyne]

Folks, 

I've been trying to find a way to stop linux from disconnecting my ssh
sessions after some idle timeout period.  I can't find any setting in
sshd_config to stop this idle timeout from occuring.  Could it be somewhere
else (such as login or in the securetty settings ?).

I only seem to get this connecting to later SSH servers.  I have a RHL7.0
box and I can stay SSHed into this for days.  For RHL7.3 and up, I get
thrown off after about 10 mins.

I don't really want to set anything on the client side - as I would have to
go and change every client I use.  I am looking for a solution on the server
side.

Thanks
Matt

[SLUG] Win2k Server and Linux - Active Directory and BIND

[Matt Hyne]

Folks, I have a question on adding a W2K server into a Linux
environment.  I don't know a lot about W2KS, but I do have a lot of
Linux experience so I am hoping someone has already done this.

We have been forced to upgrade our old 1998 NT 4.0 server to a W2K
server.  Now the new server will run Active Directory (whereas the old
NT 4.0 machine ran as a single NT domain) and I would like to know how I
can integrate this into our current DNS which is BIND running on a linux
box.

I do not want to have to create a new subdomain and run the MS DNS
service (such as ad.mydom.com.au).  I would prefer to have W2K use the
BIND DNS server and have everything under our top level domain
(mydom.com.au).  

Has anyone done this or something like it and can offer some advice ?

Also, we use a lot of Samba and our Samba boxes authenticate using our
NT4.0 server.  Now, I want to convert this to using the W2K server.
Will I have any problem since the new server runs AD ?

[SLUG] Network printing problem on RH 6.1

[Matt Hyne]

Folks, we have an old RH 6.1 server which we use as a database server.
For compatibility reasons, we need to stay with RH6.1.

However, I had to reload the machine the other night and now network
printing will not work.  I keep getting the following errors in
/var/log/messages when I try to print as any user except root (root
prints fine).

Jul 14 17:45:07 panda lpd[11257]: lpd: couldn't open spool file
dfA014panda as mhyne
Jul 14 17:45:07 panda lpd[11257]: PRINTER1: job could not be sent to
remote host (cfA014panda)

I cant see to work out what the issue is.  Everything appears ok and if
I print as root it works.  The spooler directory appears to be owned by
lp.lp.

Anyone have any suggestions ?

[SLUG] Email -> SMS

[Matt Hyne]

Folks, rather than not try and reinvent the wheel I was hoping someone
here might have done this before.

I am trying to set up an email->SMS gateway.  Users should be able to
send an SMS by sending an email to [EMAIL PROTECTED]

I would therefore like to get sendmail to forward all mail for
sms.mydomain.com.au to an external program which will do the following.

1. Extract the sender and recipients name/userid.
2. Look up the recipient's mobile number (simple looking).
3. Translate this into an SMS using an attached serial GSM modem.

Now, if someone has done it before, then all is good.  If not, then I
will code up the helper application however I would like to know what
method people suggest for getting sendmail to forward all mail for
sms.mydomain.com.au to an external program without loosing the original
envelope (ie with recipient's userid).

[SLUG] Using SAMBA/Linux to push Windows Group Policies

[Matt Hyne]

Folks, I'd love to chuck out a Windows 2000 server however it is used to
push group policies down to windows clients.  This includes such things
as the default proxy, default settings, what the user can/cannot change
and other admin things.

I was wondering if there is anyway I can do this from a Samba box - or
alternatively another way that I can do it without using a W2k server.

I'm interested in comments from people who have tackled this.

[SLUG] Getting sendmail to use nullclient

[Matt Hyne]

Folks, I need help with a sendmail config.

I am trying to get my machine to forward ALL mail through a central mail
server.   I do not want anything delivered locally (we have a central
mail server for all mail).

I have configured the sendmail.mc (cf) file to be a nullclient however
it still wants to deliver mail locally (eg if I do a "mail matth").

Here is my nullclient.mc file (which I build into sendmail.cf)

divert(-1)
dnl This is the sendmail macro config file. If you make changes to this
file,
dnl you need the sendmail-cf rpm installed and then have to generate a
dnl new /etc/sendmail.cf by running the following command:
dnl
dnlm4 /etc/mail/nullclient.mc > /etc/sendmail.cf
dnl
include(`/usr/share/sendmail-cf/m4/cf.m4')
VERSIONID(`linux setup for Red Hat Linux')dnl
OSTYPE(`linux')
DOMAIN(`generic')dnl
FEATURE(`nullclient',`panda.xx.com.au')dnl  
undefine(`ALIAS_FILE')dnl  

Here is the log of sending an email to 'matth':

Jan 16 14:32:36 wormhole sendmail[9464]: i0G3Wa809461: to=matth,
ctladdr=root (0/0), delay=00:00:00, xdelay=00:00:00, mailer=local,
pri=30030, dsn=2.0.0, stat=Sent

As you can see, sendmail still delivers this mail locally rather than
forwarding onto my mail hub.   

I've tried removing the include() above, but then sendmail complains
when I restart it:

Starting sendmail: 
No local mailer defined
QueueDirectory (Q) option must be set  [FAILED]   

Has anyone got a Redhat machine (this is 7.3) to actually work as a
nullclient ??

[SLUG] Reducing Postmaster Notify msgs from sendmail

[Matt Hyne]

Folks, each day I get about 300+ "Postmaster Notify" emails from my mail
server.  These are generally because an external email could not be
delivered to one of my users because the user did not exist (and thus
postmaster gets copied on the warning msg).

Now, most of the time, these undeliverable messages are SPAM which have
been sent to random names at random domains.  Thus these notifications
are of no value to me and all they do is fill up my mailbox.

Is there anyway to turn off these notifications to the postmaster within
sendmail ?  

We only have a relatively small domain and I would love to know how
folks on larger sites manage all these postmaster notifications.

Regards 
Matt

Yes but the argument is that in the modern internet we have today, all
SMTP servers will spool locally and retry to send mail for up to 5 days
before giving up - thus a seconary MX does not offer any advantage and
could even open up some bigger problems.

[SLUG] Secondary MX record - To have or not

[Matt Hyne]

Folks, 

A little Linux unrelated (but I suppose it is since I am using a Linux
server) but I have been having some discussions with a number of vendors
around the place regarding secondary MX records.

There seems to be two camps here - those that do not believe that they
are needed (and thus don't provide them) and those that believe that
they are a mandatory part of a redundant mail system.

I am sitting on the fence (I can see some merits to both sides of the
argument) but I was wondering what the opinion of the sluggers out there
is - would you install one and why ?

[SLUG] Problems with virtual hosts on apache.

[Matt Hyne]

Folks, I have an apache problem that is probably quite simple to fix but
I cannot find the solution.

I have set up several virtual hosts on the box and these work fine,
however I cannot get the correct virtualhost page if I drop the
domainname from the URL.

Eg (these are examples, so don't try accessing them):

I have the following virtual domains:

http://domain1.hyne.com
http://domain2.hyne.com
http://domain3.hyne.com

Now, If I use the FQDN, I get the correct pages.  However if I just use
http://domain2 or http://domain3 then I will always get the webpage for
domain1.

I've played around with the options and searched google to no avail.

Anyone got an ideas ?

OK, this is a message from inetd telling you that it keeps starting the
service up and it keeps dieing for some reason. If inetd needs to restart a
service over a certain number of times in a certain period (normally 1
minute) then it stops it assuming it's broken.

You should check:
1) Are the arguments and path to tftpd correct ?
2) Why is tftpd dieing ?

You could probably do both by using strace.

strace -f -p  -o trace.txt

That should log the system calls of inetd to a file and also trace any
children forked. You can then try the tftp from the router and see what
blows up.

good luck!
Chris

Guys, I am trying to use the tftp-server to load images onto a router, but 
whenever I access the tftpboot machine, tftp dies with the following error 
in the /var/log/messages file.

	tftp service was deactivated because of looping

I updated tftp and tftp-server to 0.28, but it did not seem to make any 
difference.
I am running RH7.0.

Anyone got an ideas ?

That's not what you asked it to do.  Try

rsync -aczessh /usr/local/ backup:/backup/hostname/usr/local/
rsync -aczessh /local/ backup:/backup/hostname/local/

Note the full pathnames on the right side and all the extra '/'s.


The biggest problem with this is that it expects the remote machine to 
already have those destination directories created - which I cannot do 
since the script will run non-interactively and only allows rsync to be 
executed from the source machine.

Are you sure you need the 'c' option?


Just another check to make sure that the file was copied without 
error.  Any good reason not to use it ?

[SLUG] rsync question

[Matt Hyne]

rsync guru's

I am trying to write a backup script that will run each night to mirror 
some of my directories on another machine (the backup machine).

Basically I have a script that produces the following (it is actually a 
shell script that gets the source directories from another file).

rsync -acz -e ssh /usr/local backup:/backup/hostname
rsync -acz -e ssh /local backup:/backup/hostname

So I am attempting to rsync /usr/local and /local and clone these as 
backup:/backup/hostname/usr/local and backup:/backup/hostname/local

The problem is that rsync puts BOTH of these in 
backup:/backup/hostname/usr/local which is not what I want.  Does anyone 
know how I can tell rsync to use the full path in the destination, rather 
than the last directory.  I do not really want to have to specify the 
entire dest directory as this will stuff my automagic scripts.

Yes and no.  The SCSI bus will default to the slowest speed only when doing 
transfer to that device.  If you are using the HDD and not the scanner, the 
bus will run at the highest speed supported by the HDD and host adaptor.

[SLUG] Printing Problems with CUPs

[Matt Hyne]

Folks, I have been wading through the confusing world of linux printing and 
CUPS and I am hoping someone can help.

I have a linux box that is connected to a couple of LPD line printers 
(dot-matrix, no graphics). Now if I configure these as raw printers under 
CUPS then I can print fine however I need them to issue a From Feed at the 
end of each job.

I used to be able to do this with LPRng, but CUPs does not seem to allow me 
to do this.

I was wondering if anyone has any ideas or suggestions ?  I was looking at 
foomatic and cupsomatic and their PPD files but this all sounds 
over-complicated as they are printing output to Postscript and then 
converting it back to raw text.  I dont really want to do this just to add 
a FF to the end of the job.

I've got one which I have already returned once - it keeps locking up 
requiring a power-cycle to fix.  I am probably going to return it for a 
refund, it has some serious bugs.

[SLUG] Samba and Linux Help - I need a refresher

[Matt Hyne]

Folks,

It has been some time since I played with Samba and I wanted to find out 
what the current status is with regards to setting up a Samba box as a 
Network Attached Storage box.

Basically, I want to use a Linux box as a storage server on a Win2K 
domain.  I have it set up to do server authentication from a PDC (seems to 
work).  Do I also have to create local userids in /etc/passwd for all the 
users that will be using this via windows (what about smbpasswd) ?

I know there are a lot of organisations selling Linux boxes as storage 
servers (throw on a HTML GUI and you're done).  They claim they can just be 
plugged-in and configured - and that there is no need to configure local 
usernames or passwords.

What happens when users save files - how does the win2k username of the 
user get translated to a linux UID if there is no local userid ?

Has anyone used winbind to authenticate Linux users from an NT/2k Server 
?  It would be good if I can do all the userid/password maintenance on one 
machine without having to add a local userid to a linux box.

Lastly, anyone had any success using Samba as a PDC or BDC with Windows 
2000 clients yet - I would love to replace a Win2k server we have here ?

[SLUG] Document management system

[Matt Hyne]

I am looking for a free/GPL document management system that runs under linux.

Basically, we have a number of project files that we want users to be able 
to check in and out when they make changes (word docs mainly).  I would 
like them to be able to do this via a web interface.

Ideally I am looking for some sort of PHP based system (ie, so I can change 
it).

Anyone got any suggestions ?

PS: CVS is a little hardcore for some of our users - so that is not really

It appears to be sending a request to the auth protocol of the external 
machine - which it does  4 times before getting a response (the reason for 
the 30s delay).  The problem with this is that there is no guarantee than 
an external machine does not block inbound access to the auth protocol 
(with many stateful firewalls this is normally the case - only open a port 
if there was an outbound connection first).

Is there anyway to tell the pop daemon NOT to try to reconnect on the auth 
port ?

[SLUG] Problem accessing POP server remotely

[Matt Hyne]

Guys, I asked this problem before but did not get a solution.

Basically, I am running a home POP server and when I access this POP server 
remotely, it takes some 20secs before POP starts to transfer mail 
(internally it is immediate).

If I telnet to the POP port directly, I see that indeed the following occurs:

 > telnet  pop
Trying www.xxx.yyy.zzz...
Connected to .
Escape character is '^]'.
+OK POP3 panda v2001.78rh server ready

And it takes a good 20s before the +OK POP3 ... line is displayed.  It is 
not latency on the link - telnet/ssh is immediate.

I though it might be because of the auth/ident protocol so I check I can 
access this remotely, which I can.

So I am at a bit of a loss to explain why this problem persists.  Anyone 
else seeing this problem too (machine is a RH7.0 box) ?

[SLUG] POP problem

[Matt Hyne]

I have noticed that if I attempt to POP mail off my home machine (Redhat 
7.0), from work, it takes a long time for eudora to connect to the machine.

So I did some testing and I did a 'telnet  110'.  The tcp connection is 
set up immediately, however it can take up to 30 seconds for POPD to give 
the 'POP3  server ready' message.  It looks like it is taking this long 
for xinetd to start /usr/bin/ipop3d.

However, connecting to it from the local LAN or localhost gives it instantly.

Doing an SSH, www or any other protocol also works instantly.

Anyone got any ideas ?

Ok, now I have no idea what I am doing, but I am trying to install some

there is a perl expert out there that can put me back on the rails.

Compress::Zlib

but I get the following error:

It tells me it is missing zlib.h, which I would expect to be part of the

Has anyone else had any experience with this and can offer some advice.  I 
am not a perl expert and this is the first time I have used the CPAN stuff 
- so go easy on me.

[SLUG] mail problems - MX records.

[Matt Hyne]

Guys, I have noticed a mail problem on my mail server (my private one :-) ).

External mail to [EMAIL PROTECTED] works file, however, if someone sends mail 
to [EMAIL PROTECTED] it never makes it to my SMTP server.

I checked the MX records and it correctly shows my MX record for hyne.com 
pointing to my SMTP server.

The server is working - because mail to hyne.com is received fine.  The 
logs don't even show any delivery attempts to host.hyne.com.

Do I need a separate MX record for host.hyne.com - or should the domain MX 
catch all ?

it can be updated easily would be a reasonable amount of work - and I would 
prefer a tool, than having to hand modify the database everytime I want to 
make a change.

Suggestions ?

Re: [SLUG] Booting problem with SCSI machine

[Matt Hyne]

Thanks Glen for the in-depth description.

All make sense, but I am still at a loss.

1. The boot bios is enabled.
2. SCSI device is on ID0.
3. SCSI runs fine once linux is loaded from a floppy.

So it is damb weird.  The is detected ok, but the BIOS fails to see an OS.

Well, the kernel does have the support - since it is also on the boot floppy.

I know the SCSI card is bootable as before linux it was running BSD and 
booting this from the HDD.

(The SCSI controller is on board the Intel motherboard)

[SLUG] CDRW on Linux as a backup medium.

[Matt Hyne]

Has anyone successfully used a CDRW on linux for backups ?

I am looking to buy one of the cheap LG (IDE) ones now on offer.  However 
the drive docs state that it is only capable of reading CDs under Linux and 
you need Windows XX to record or rewrite.

Can a CDRW be formatted under Linux ?

[SLUG] Booting problem with SCSI machine

[Matt Hyne]

I have been having trouble getting a machine to boot lilo (or anything from 
HDD) after an install of RH7.3.

Lilo is installed (and I ran it again for good measure) but the only way I 
can get linux to boot is to use the boot floppy I created at install time.

The machine is a PII-400 with an Intel MB, NCR SCSI adaptor (sym53c8xx) and 
a 4.3Gb HDD.

I also tried recreating the initrd (and it is in lilo) but still it tells 
me that there is no operating system found when it try to boot the disk.

Any ideas ?

Re: [SLUG] BPB ADSL & PPPoA

 From what I understand, these are the Speedtouch Pro models which can do

DSL port.

[SLUG] Pacific Internet ADSL

[Matt Hyne]

Is anyone running Pacific Internet ADSL ?

I am tossing around a few ADSL providers looking for the ones with good 
rates vs good performance.

So far, Pacific Internet and Netspace are my preferred, however when I 
ping/traceroute Pacific's servers (a week or so ago), I get very long 
response times (>100ms) whereas Netspace are a lot less (<30ms).

I would like to try a ping and traceroute test to a Pacific Internet ADSL 
endpoint to test their network performance prior to ordering a service.

If anyone can spare a couple of pings on their gateway, could you please 
let me know the IP address.

I would also welcome any feedback either carrier's network, support, 
performance.

Re: [SLUG] Problems with Telstra Cable that have been happening over the last 3 days

[Matt Hyne]

There are a number of ways around it - but it is not the nicest way to do 
it.  Split-horizon will work (different routes for secure and Internet 
traffic) - but like mine, many orgs don't allow this for security reasons.

It would be much better if Telstra just scrapped it.

I've thought about adding support for this into Cisco's IOS - but getting 
time is the problem.

[SLUG] Problems with LDAP authentication

[Matt Hyne]

I have been having a problem with Red Hat 7.2 configured for LDAP 
authentication.

The authentication works.  However, if the LDAP server is down, I cant even 
log in as root.

root and other users are listed in the /etc/passwd and /etc/shadow files, 
however these do not seem to be read if LDAP is down (even though the LDAP 
server does not even contain root or these other users).

Here is (part of) my nsswitch.conf file:

# The following is required to make the system
# check the local passwd files for netgroups then
# the LDAP server...
#
passwd: files ldap
passwd_compat: ldap
shadow: files ldap
group:  files ldap

and the pam stuff is:

[SLUG] Backup Mail servers (OT)

[Matt Hyne]

Folks, finally got my old man's business online and everything except the 
desktops is running linux (database, gateway, servers).

I'm setting up the mail and DNS.  The ISP says they cannot give us a backup 
mail server to host a secondary MX.

Does anyone know of any (reliable) groups, ISPs or other organisations that 
will provide backup/secondary mail servers and secondary DNS services ?

Does anyone do any reciprocal agreements (you backup me and I will do you) ?
My next resort is one of the 'free' services.

The problem was that I missed the full-stop on the end of the MX record in

The only question I have is:  With this feature enabled, won't sendmail 
refuse to accept mail if the internet connection goes down, and thus it 
cannot reach external DNS servers ?

Re: [SLUG] tar backups to tape

[Matt Hyne]

You can try using tar with the I flag - that will use bzip2 compression.

However, if you value your data - NEVER use compression on a backup - 
should part (ie one bit) of the backup be corrupted (common with tapes) the 
whole archive is useless.

Re: [SLUG] tar backups to tape

[Matt Hyne]

If Arkeia is backing up at 180Mb/min then this is equivalent to 3Mb/s, 2-3x 
faster than tar.

Is Arkeia using compression ???  It is possible, and that may be why it is 
reporting faster transfer times to tape than tar is.

You can also play with the tar blocking factor - it will depend on the 
network transfer speed.

The other thing is, what sort of tape drive are you using, what sort of 
controller ?  What is the maximum rated transfer rate for the tape drive ?

Another stupid question - is Arkeia doing a FULL backup or an incremental ?

 From the look of this, you network is probably not the bottleneck.  I 
would also suggest you take a look at ctar (do a google search).  It costs 
money but you can install a trial version and compare that.

Re: [SLUG] tar backups to tape

[Matt Hyne]

Generally, tapes are streaming, so it is possible that if the transfer rate 
across the network is slow then more tape may be required for the same 
amount of data.

Really - you need to determine the bottleneck - can you tar from one 
machine to the HDD on another and see how long it takes - and then locally 
tar this data to the tape drive.  That should give you some good ideas of 
where the performance bottleneck is.

Re: [SLUG] Redhat 7.2 crashes my computer

[Matt Hyne]

I would not suggest upgrading RH kernels using RPM.

Honestly, I would download the latest kernel source from 
mirror.aarnet.edu.au (I am using 2.4.18 at the moment) and build my own - 
at least then you know what you are building into it.

If you have not built a kernel before, it is pretty easy and there are many 
docs around (including the docs included with the kernel source).

Email me if you need a hand.

Re: [SLUG] Redhat 7.2 crashes my computer

[Matt Hyne]

Are you using the default Redhat kernel ?

I was having lots of freezes/crashes until I upgraded the kernel and now it 
has been running for 4 weeks without a problem.

I was pretty sure it was not the machine (P90) since it had been running 
RedHat 5.2 since it was released and had general uptimes of approximately 
200+ days.

[SLUG] NFS mounting between RH7.0 and RH7.2

[Matt Hyne]

I am trying to mount a filesystem from a RH7.2 system on a RH7.0 
machine.  However mount fails with the following errors:

[root@panda /mnt]# mount -t nfs wormhole:/export/backup /mnt/misc
mount: wrong fs type, bad option, bad superblock on wormhole:/export/backup,
or too many mounted file systems

and -

Mar 30 17:50:07 panda kernel: NFS: NFSv3 not supported.
Mar 30 17:50:07 panda kernel: NFS: cannot create RPC transport.
Mar 30 17:50:07 panda kernel: nfs warning: mount version older than kernel
Mar 30 17:50:08 panda kernel: nfs: too small RPC reply size (0 bytes)
Mar 30 17:50:08 panda kernel: nfs_get_root: getattr error = 5
Mar 30 17:50:08 panda kernel: NFS: cannot create RPC transport.

Now, the blindly obvious is that the RH7.2 machine supports NFSv3 and RH7.0 
does not.

Is there a way to make the RH7.2 machine support the same version of NFS as 
is on RH7.0 - ie backwards compatibility ?

No, I am using 2.0.21 but I finally did get it to work by reverting 
to unencrypted transactions on port 389.  I cannot seem to get the 
LDAP over SSL stuff to work.  Must be something to do with certs. 

I will have to get the security sorted out as I am not to happy about
leaving it open.  I also want to tie squid, apache and radius into
using the LDAP database for authentication and finally find something
that I can use to nicely manage the users and groups now in LDAP.

One other question.  From memory, in NIS we can control what groups of 
users can log into a machine using netgroups and by prefixing the 
username/group with +.  Is there a way of doing this with LDAP ?  Ie, all
users are in the ldap directory and I have two machines which I would like
to restrict a subset of users to.

Yep - except that the schema files for the attribute types used by the PADL migration 
tools are not included in the RH LDAP distribution - doh !

Anyway, I have hacked the migration scripts to remove the unknown attributes and the 
database build ok. 

The only problem I have now is getting pam_ldap to access the LDAP database. It tells 
me it cannot connect when I try to authenticate via LDAP.  I believe this must be 
something to do with /etc/ldap.conf or /etc/openldap/ldap.conf but I don't know which 
one yet.

[SLUG] Problems migrating to LDAP passwords

[Matt Hyne]

I have been trying to migrate a linux box over to LDAP passwords but I have been 
running into a few problems with the migration stuff.

I am using RH Linux 7.0 and I have the LDAP database up and running ok.  The problem 
is when I use the migration scripts (in /usr/share/openldap/migration or the latest 
from www.padl.com) they attempt to use attribute types or object classes that are not 
supported by my ldap schema.

If I get the name of afailed attribute (eg objectClass 'mailRecipient') and search the 
schemas for this I get no result - so it looks like RH have packaged the migration 
tools without including the proper schemas.

Anyone had any luck with using the (padl) migration tools and can offer their advice ?

[SLUG] Distributed passwords

[Matt Hyne]

Guys, I have number of linux boxes here and I want to only have one place that

Anyone with experience - any interesting links ?

It was my impression that none of the Journalling fs are recommended for production

If no so - correct me - I am interested to know.

Well, that depends.  From his config, both external IPs were on the same subnet so the 
ISPs router probably could be bypassed using a static route.

We need to know more about the public side of the network.

The only VPN solution I would recommend would be IPSec - ie FreeS/Wan.  Others have a

Two different subnets makes life hard.  I am also suprised that the external network 
addresses are on the same subnet - is this on the same ISP ?

If the two networks are truly connected on the same external subnet then life is 
pretty easy however since you are running your traffic over a public network it is 
well recommended that you use IPSec for security.

To get basic routing working, you could divy your 192.x.x.x network into two smaller 
subnets, or renumber the one at the other site.  Then all you would really have to do 
is add some static routes into the linux box at each end pointing to the other 
router's gateway (external) address.

Even better - I may even be able to dig up a router (on loan) with a FXO/FXS interface 
you can use.  

You can then play VoIP and mini-ISP.

[SLUG] Backup solutions

[Matt Hyne]

I am looking at a way of doing a SIMPLE bare metal recovery plan for my development 
linux box.

What I am interested in hearing is people's comments on using 'tar' or 'dump' as the 
backup program and why I would use one over the other. (ie restrictions, advantages 
etc).

My main requirement is that I be able to restore the tape on a totally new machine 
should my old machine go up in smoke.  This would mean that such things as 'dd' cannot 
be used since the new hard drive probably won't be the same size as the old one.

I am currently using "tar" to backup to a QIC tape.  I also have a bootable 
crash-recovery CDROM that I can use to boot a new machine and then restore the tape 
from.

Comments ?

All PAT/NAT does is translates the private IP address to a public ip+port via a lookup 
table using the src and dst ip addresses/port numbers.  

Each session will have a different translation thus each path's MTU is retained.

[SLUG] Filenames with spaces - and using a shell script.

[Matt Hyne]

I am trying the write a little script to convert some MS Word files to HTML, however 
some of the word files contain spaces in their name.

Hense, when I use the couple of lines below, it treats the space as a delimiting 
character and chops up the filename.

Anyone know how to get around this without renaming all the files (some 350).

Ie

for FILE in `ls`; do
echo "Converting $FILE..."
done

Converting xxx...
Converting yyy...
Converting zzz.doc...

[root@panda MSDS]#  ls -l xxx\ yyy\ zzz.doc 
-rwxr-xr-x1 root root50 Oct 26 14:40 xxx yyy zzz.doc
[root@panda MSDS]#

Re: [SLUG] was: Internet Connection

[Matt Hyne]

Actually, initial studies of the security on Optus left a lot to be desired.  There 
were many reports of people stealing the IP address of other users and using this to 
avoid clocking up their own bandwidth usage (and the poor bloke who owned the IP 
address would get slugged with the excessive bandwidth, and probably disconnected).  

Now it appears they are doing their accounting based on MAC address - still not good 
enough since it is very easy to change the MAC address of a cable modem to that of 
another user.

This works providing the other user is not connected.

Having said that, the Optus policy on disconnection is that they have no problem with 
people reconnecting again - they just want you to pay the connection fee again.

Re: [SLUG] ADSL, modem or router

[Matt Hyne]

Unbiased view - 

It all depends on what you want to pay.  The Cisco 827 is a nice little router, is 
simple to setup, has a stack of features and will work stand-alone, but if you want to 
keep costs down then run a Linux box with PPPoE to a ADSL modem.

Your carrier will probably give you the option of a DSL modem.  There are plenty of 
others around - some do NAT, many do firewalling of some sort.

[SLUG] RedHat Network 'up2date -u' fails with RPM conflict.

[Matt Hyne]

Using the redhat network to update my RH box, I am not getting the following failure 
when attempting an 'up2date -u'

Testing package set / solving RPM inter-dependencies...

RPM conflict error.  The message was:
Test install failed because of package conflicts:
file /usr/X11R6/lib/modules/pex5.so from install of XFree86-3DLabs-3.3.6-38 conflicts 
with file from package XFree86-I128-3.3.6-33

Q: Basically it is saying that pex5.so is in both these packages - but how do I fix 
it, without stuffing the RH Network config/database ?

Overall, I've been pretty happy with the RHN - works well at upgrading.

Re: [SLUG] own domainname with non-permanent connection?

[Matt Hyne]

I know with www.dns2go.com that you can tell it to set your IP address to 0.0.0.0 
when/if you go offline (regularly if you use Telstra ADSL).

Generally, a static IP addr on Telstra's ADSL network will set you back a considerable 
amount for little more gain - they consider this a bigpond direct service and thus 
charge the big bucks for the same speed etc as the standard dynamic ADSL service.

Another option is to config sendmail to fetch you mail using the ETRN (??) command - 
that way, the mail will be stored on a secondary server and you initiate the transfer 
to the primary when you are up - and list mail (non TO: addressed mail) will work too.

[SLUG] Apache serving .doc files

[Matt Hyne]

I am trying to get my Linux based apache web server to serve some .DOC MS Word files.  
However I am having the following problems.

1. When I click on the link, the file starts downloading as (garbled) text into the 
netscape window.
2. If I shift-select the link, I can download the file but then WORD cannot read it.

I've checked the file in Apache's directory and it is fine - I can ftp or scp it and 
read it just fine, just not when I try to fetch it from a link on a webpage.

I have the following link set up in my webpage:

FAX Coversheet (Word)

Anyone got any ideas - have a got Apache configured wrongly.

[SLUG] PPTP or IPSec Windows Client to Linux Server

[Matt Hyne]

Has anyone had any success connecting a Windows client machine to a Linux VPN server 
using PPTP or a IPSec.  I am also looking for a FREE Windows IPSec client.

I've read some HOWTO's but they don't really go into this all that much.  I want to 
use an existing windows VPN client or one that is free, secure (lets not talk about 
PPTP and secure - I know) and able to talk to a Linux VPN server.

SSH is currently being used but does not give me the features that I want to play with.

Re: [SLUG] Telstra ADSL & Debian vs RedHat

[Matt Hyne]

I've seen minimal problems with ADSL reliability however the advertised performance vs 
their actual performance does vary. (Actually, redundancy is something that Telstra 
have yet to discover - when they do the outages should go to almost 0).

I've run some tests between two Sydney connected ADSL sites running various traffic 
streams with different packet sizes and find that the best throughput I can get is 
60kbps (on 512/128 -> 512/128 services).  I contacted Telstra about this and they 
advised that they only advertise the physical capability of the service not what you 
will actually get (what crap).

If I designed an ISDN router that promised 128kbps throughput and only gave customers 
60kbps I'd be out of a job.

I'm not finished with them yet.

[SLUG] Using SSH server with Netscape.

[Matt Hyne]

I am trying to setup SSH so I can use a windows based SSH client to tunnel netscape 
(http) traffic through the SSH connection.

I have the client side set up and all http requests are going out over the SSH 
connection as required but the linux box that is the SSH server is not forwarding this 
traffic.

In my client browser I get a reply from apache (running on the SSH server) telling me 
the following:


Forbidden

You don't have permission to access http://203.21.94.11/ on this server.

Apache/1.3.14 Server at panda-new.cleveland.com.au Port 80
-

Why is it going through apache on the SSH server ?  Shouldn't this have nothing to do 
with apache?

Does anyone know if I have to do anything special in the SSH server config so that I 
can get netscape to use the SSH connection as a tunnel.  I know the client side is 
configured ok because the SSH server is seeing all the http traffic ?

[SLUG] Cisco ADSL router config for Telstra ADSL network

[Matt Hyne]

For those that requested it, here is the config I have successfully used on the 
Telstra ADSL network.

This configuration has been tested on the 827 series but should also work on any 
router with an ADSL WIC card.  

Ensure that you set up the enable and secret passwords and I also suggest username 
security.

I have also added PAT translations to show you how to get your Web server and SSH 
server to respond to the Telstra allocated IP address.

I have been using a dynamic DNS service (dns2go) on a Linux box inside so I can telnet 
to the router's public dynamic IP address using a FQDN.  

Using the PAT translations in the config, this should also work for setting up your 
own mail server too since Telstra don't plan to offer private IP addresses on their 
ADSL network for some time and they will be expensive when they do.

Hope this helps.

Matt

Re: [SLUG] Cisco 827 ADSL Router

[Matt Hyne]

Have it running nicely - even with a dynamic DNS service and NAT+PAT to pipe certain 
ports through to a linux server.

I will post the config here later today.

In my opinion that is a poorly designed network if there is no redundancy or backup.  
For a carrier that screams for 99.999% reliability, they only have their selves to 
blame.

[SLUG] Telstra ADSL offerings.

[Matt Hyne]

I've been trying to get some sense out of Telstra for weeks but just hit a brick wall.

Does anyone know whether Telstra offer a STATIC ip address for ADSL users.  I have a 
NAT-ed network that I would like to be able to set up PAT on so I can receive an SMTP 
and SSH feed.

Does anyone know what brand/model of ADSL modem/router Telstra offers ?  Does it have 
only an single ethernet port or is there a ATM25 interface as well ?

Is their PPPoEoA authentication client a Windows based thing or can I just get the 
router to authenticate and treat it like a DDR link ?  I have linux boxes on the 
network, but I would prefer not to have to run a DSL client on these - I just want to 
treat the DSL router like a gateway to the internet.

No this will not work - you need a DSLAM at the end of the copper, and then something 
to authenticate and forward your traffic to the ISP that you use.

You can set up a GRE tunnel from your DSL router to your company's router and only use 
the telstra network to forward traffic across this tunnel.

[SLUG] Fetching mail from a remote mail server

[Matt Hyne]

Folks, I've been asked by a family member if I can help them with their email system.

They are running a Linux server + database which is connected to the net via a 
dial-on-demand modem.
What we want to do, is have all the mail for the domain (ie all mail to 
mydomain.com.au) downloaded by the linux box and then redistributed to the users' 
mailboxes.

Now I have looked at this in the past and I found that there are problems with using a 
central mailbox and a single POP client such as fetchmail to do the job.  In 
particular, if the destination email address is contained in a bcc: field (ie from a 
list or alias), there is no way of the local system knowing who the email is destined 
for.  This also applies to email sent from a forwarder.

Does anyone know of any other methods that would be appropriate.  The mail volume is 
quite low - < 30 emails a day.  

I have also thought that UUCP over IP (and then pipe this to sendmail) might me 
appropriate - are there any ISPs that can handle this (cheaply) ?

Outbound mail works fine via sendmail - anyone know how to make sendmail queue, rather 
than bring the link up for each message ?

When you say it wont boot - what do you mean.  Do you get a BIOS message
if you plug the monitor back in.

Most BIOSes allow you to turn off the BIOS video support, so it
doesn't need a monitor.  

You can even re-direct lilo and the kernel message output to the serial
port and make it really headless like most other unix machines.

I've been running a headless box for ages.

[SLUG] New RH 7.0 Respin ISO images

[Matt Hyne]

Can anyone tell me what the RedHat 7.0 RESPIN ISO images have that the old ones didn't 
?

ie: 7.0-i386-respin-disc1.iso, 7.0-i386-respin-disc2.iso

Further, there now also seems to be a file called 7.0-i386-upgrade.iso.  
Anyone know what the hell this is ??

As usual, there are no docs to go with them.

I've been trying to find out from Telstra whether they plan to offer routed subnets on 
their ADSL service but it seems like no one knows a thing.  I've seen more of the 
Telstra switchboard than I have of their customer service folks.

>anyone know whats become of optus and xyzed.com.au ?

xyx.com.au are only going to sell to ISPs - who will then sell it to the end users.

Re: [SLUG] Any Modem Gurus?

[Matt Hyne]

If you can connect and ping, there is nothing wrong with your modem.

Can you ping the DNS addresses in /etc/resolv.conf  - if you can, then it is probably 
a problem with your config.

If you cannot, then I suspect these are the problem.
