file sharing stopped working [Solved]

[Pastcal]

Suddenly (last 10 days or so) I can't access files in the 'Public' folder over the network, whereas before I could. Significantly, in Thunar when I click 'Browse network' then the name of the system (in this case badgers-mint2) I don't see the files that are there.

I've followed the advice in HowTo: Samba Browsing Problems Checklist at http://forums.linuxmint.com/viewtopic.p ... 46&start=0

I've appended the output of ifconfig, nmap and testparm below. Can anybody see anything wrong or suggest further actions? Thanks

You have a couple of issues here but ....

You have no shares defined in smb.conf so there is no Public share to access.
Did you create them using samba usershares? To find out post the output if this command:

Code: Select all

net usershare info --long

And then there's this:

rover@badgers-mint2 ~ $ sudo nmap -sS -sU -T4 192.168.0.105
sudo: unable to resolve host badgers-mint2

Post the output of these commands:

Code: Select all

cat /etc/hosts
cat /etc/hostname

There should be a reference to badgers-mint2 in both files.

Hello there Altair4, thanks for the help. In the meantime I've changed the system name to remove the dash. Here's the output. :


rover@badgersmint2 ~ $ net usershare info --long
rover@badgersmint2 ~ $ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 badgersmint2.workgroup

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
rover@badgersmint2 ~ $ cat /etc/hostname
badgersmint2
rover@badgersmint2 ~ $

[altair4]

The two files have to match host names.

/etc/hosts should look like this:

127.0.0.1 localhost
127.0.1.1 badgersmint2

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

But the real problem here is that you have no public share.

Why not just edit /etc/samba/smb.conf and add one at the end of the file:

Code: Select all

[Public]
path = /home/rover/Public
read only = no
guest ok = yes
force user = rover

Then restart samba:

Code: Select all

sudo service smbd restart

Then

Code: Select all

sudo service nmbd restart

Wait a few minutes after restarting the nmbd daemon or else Windows gets confused.

@Altair4 - A big thanks, editing smb.conf as per your advice fixed the problem. You're a smart guy. Mind you I'm suspecting you've been using the Krell machine...better watch out for those monsters from the Id!
