Post subject:  SMB mount on boot without password, possible?
Getting crazy over this, but here it goes:

Trying to mount an mp3-folder from a WindowsXP-based SMB-shared computer over the network at boot from /etc/fstab. Problem is, it doesn't have a password since it's guest-accessed. But the fstab doesn't seem to like that, since if I leave the password field blank it asks me for a password IN THE BOOTSEQUENCE, and it's pretty hard to input a password with a remote...

So, is there a way to make it accept a blank password and just mount the darn smb-volume?

Here's the command I give in fstab:
Code:
//Swiftfoot/mp3 /myth/music/swiftfootmp3 smbfs username=swiftfoot,password=   
//Swiftfoot/ra_5 /myth/video/motion/swiftfootvideo smbfs username=swiftfoot,password=

What if you don't include the "password=" option in fstab?

Sorry, mixed them up. If I HAVE the password= then it says "authentication failed" when booting up. If I DON'T have password= at all then it stops at boot and asks for a password.

Solved this intermittently by simply adding a cronjob ever 5 minutes to mount the smb-shares with smbmount. Works fine, but it's a bit kludgy.

a little better solution than a cron job would be to mount them in bootmisch.sh if you can do it in cron you should be able to do it there, and it only runs once on boot instead of running every 5 minutes.

Can't find the bootmisch.sh anywhere on the drive.

find / -name "bootmisch.sh"

I have used both the bootmisc.sh (/etc/init.d) as well as the fstab method... Both work fine but if you are going to use fstab, I found it works better if you create a "credentials file" (in the example below it is /home/smb.txt) and use "credentials=" in the statement instead of "password="...

my bad typo but it's already been corrected above.

Np, thanks guys. Guess I'd be well off learning some deduction ;)

Btw, the smb-server will go on/off intermittently so perhaps I'm better of with a cron-job after all :)

OT, but the only problem I have now is that myth locks up time and again for sometimes a minute, most often while showing the program viewer and weather, and strangely enough when pressing esc while on the root-menu (to shut mythfrontend off).

I don't have access to a terminal window so I can't see if there are any problems. Know how to access one from within the mythfrontend app?

no you can't access an xterm from within mythtv, however if you ssh in you can look at /home/mythtv/.xsession-errors (might be slightly wrong it's from memory) and it should show most of the errors.

Just a few suggestions: If it's linux to linux, have you considered nfs? It really works much more seemlessly in a pure linux/unix enviroment as far as permissions/ownership, etc. If that won't work for you, I'm sure you have your reasons.

Also be sure to chown root:root your credentials file and chmod 400, since it will have the password in clear text.

In some situations, I can't remember which ones, if the password has special characters like $ or other characters that the shell interprets, you may have to escape those characters to take away their special meaning. So if your password is pa$$w0rd, you would need to put pa\$\$w0rd. I think the credentials file is one of these situations.

And lastly while I haven't used smbfs that much (I use it extensively in windows->linux though) if it behaves like nfs, your smb server going down intermittently can make things very unhappy on the client side, especially if you're reading or writing a file on the server, or sitting in a directory on the server. On the other hand if the server goes down and comes back up later the share *should* still be mounted.
