Really noob issue with hostname (samba, hostname resolution)

degmic71 · 2013-08-03 03:05:38

Simple one hopefully for you guys:

I can ping my laptop, FedoraMTD, but the laptop cannot ping me (ArchBoxMTD), but can as the IP address 192.168.11.30. Is there something that is messed up?

ArchBoxMTD /home/mikeyd  # hostname
ArchBoxMTD

I can ping the laptop fine, so I am guessing I have some sort of error in my laptop (FedoraMTD) smb.conf?

mikeyd@ArchBoxMTD ~  $ ping -c 2 FedoraMTD
PING FedoraMTD (192.168.11.13) 56(84) bytes of data.

I should also mention that I *can* connect from my Fedora laptop via :

smb.conf From FedoraMTD:

# This is the main Samba configuration file. For detailed information about the
# options listed here, refer to the smb.conf(5) manual page. Samba has a huge
# number of configurable options, most of which are not shown in this example.
#
# The Official Samba 3.2.x HOWTO and Reference Guide contains step-by-step
# guides for installing, configuring, and using Samba:
# http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# The Samba-3 by Example guide has working examples for smb.conf. This guide is
# generated daily: http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# In this file, lines starting with a semicolon (;) or a hash (#) are
# comments and are ignored. This file uses hashes to denote commentary and
# semicolons for parts of the file you may wish to configure.
#
# Note: Run the "testparm" command after modifying this file to check for basic
# syntax errors.
#
#---------------
# Security-Enhanced Linux (SELinux) Notes:
#
# Turn the samba_domain_controller Boolean on to allow Samba to use the useradd
# and groupadd family of binaries. Run the following command as the root user to
# turn this Boolean on:
# setsebool -P samba_domain_controller on
#
# Turn the samba_enable_home_dirs Boolean on if you want to share home
# directories via Samba. Run the following command as the root user to turn this
# Boolean on:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory, such as a new top-level directory, label it
# with samba_share_t so that SELinux allows Samba to read and write to it. Do
# not label system directories, such as /etc/ and /home/, with samba_share_t, as
# such directories should already have an SELinux label.
#
# Run the "ls -ldZ /path/to/directory" command to view the current SELinux
# label for a given directory.
#
# Set SELinux labels only on files and directories you have created. Use the
# chcon command to temporarily change a label:
# chcon -t samba_share_t /path/to/directory
#
# Changes made via chcon are lost when the file system is relabeled or commands
# such as restorecon are run.
#
# Use the samba_export_all_ro or samba_export_all_rw Boolean to share system
# directories. To share such directories and only allow read-only permissions:
# setsebool -P samba_export_all_ro on
# To share such directories and allow read and write permissions:
# setsebool -P samba_export_all_rw on
#
# To run scripts (preexec/root prexec/print command/...), copy them to the
# /var/lib/samba/scripts/ directory so that SELinux will allow smbd to run them.
# Note that if you move the scripts to /var/lib/samba/scripts/, they retain
# their existing SELinux labels, which may be labels that SELinux does not allow
# smbd to run. Copying the scripts will result in the correct SELinux labels.
# Run the "restorecon -R -v /var/lib/samba/scripts" command as the root user to
# apply the correct SELinux labels to these files.

It depends on your router, and whether it is acting as a DNS server, and if it is keeping track of the hosts that are attaching to it and including its DHCP assignments in those DNS results. Most consumer routers get a fail at this. Part of the reason is that both Apple and Microsoft have their own independent means of doing local machine discovery. I don't know what Microsoft calls their system this week, and I do not care. Apple uses something called Bonjour. To use Bonjour on Linux, you may want to look into Avahi. Some distributions (Fedora?) support it out of the box.
