Well, I was off sick today and thought: Time to do some of those little jobs I'd been meaning to do to my Mythbox.
I ran into some problems and I will recount them to try and give you an idea of where the problem came from.
After watching some live TV, i got my wireless card up up, by running netcardconf again through an Xterm (having to do this by hand atm) - result: able to get online with Myth
Started looking at this web page http://mysettopbox.tv/phpBB2/viewtopic.php?t=12040&highlight=
Copied the lircd.conf with the one on the page. I dropped the mouse and got all sorts of popups appearing from the linux environment.
Tried to change the name of the lirc_pvr150.ko file to this lirc_pvr150.ko1 instead of deleting it.
Now no longer am I able to connect to the backend. I get the popup telling me to check the address.
I've tried to repair Mysql, which does not find any errors.
I've tried to access it through Mythweb, but can't connect, even though it is set up right.
Suggestions greatfully received before the girlfriend arrives home later.
And on reboot, I've lost my internet connection so can't so this from my mythbox.

Some more information: (A little more precise too)
Myhtbackend.log reports:
Quote: QMYSQL3: Unable to execute query
Database error was: Can't connect to local server trough socket 'var/run/mysqld/mysqld.sock' (2)
2006-12-04 10:31:21.349 DB Error (Get overlapping programs 1) and this appears to have been repeated in several places the tail section of this log reports: Quote: 2006-12-04 12:45:15.963 Driver error was [1/2002]
QMYSQL3:Unable to connect
Database error was: Can't connect to local server trough socket 'var/run/mysqld/mysqld.sock' (2)
Q5qlQuery:: exec. database not open
Q5qlQuery:: exec. database not open
2006-12-04 12:45:16.018 DB Error (KickDatabase)
Query was: SELECT NULL
No error type from Q5S1Error? Strange....
2006-12-04 12:45:16.069 Failed to init Myth Context, exiting.
Pretty sure that's it, but internet connection is down so had to copy then type this manually.

Right, the sickness that ails me is receding: so I'm a bit more on the ball today.
So, atm the frontend of my standalone box appears not to be talking to the back end (I'm hopeful that the backend is still doing it's thing, as there are several shows I had recorded I wanted to watch.) Somehow, the link appears to be broken.
It appears to be polling the backend for information, but can't connect. This means no live TV, recordings or status reports, but I can watch DVD's and .avi's etc. As in my previous post, there remains a fair old bit of space on hda1. Not much on hda3, but that is no biggie (as long as auto expire still is working.)
Now, how can I get the frontend to access the backend? I have already tried to repair the Mysql, and it reported no problems.
I've had a scout through some of the .log files and haven't seen anything overtly untoward (apart from what I posted earlier.)
I'm stuck. Suggestions on what to do please. - After all this time fiddling with Linux, I still don't know very much.
Oh, btw, I've rerun mythtv-setup and checked the ip address for the backend. It's still correect: 127.0.0.1

Doesn't sound like MySQL is running. What is the output from
Code: ps -ef | grep -i sql And what do you see if you run Code: /etc/init.d/mysql start
BTW, the frontend and backend are on the same system, correct? And which version of KM are you playing with here?

Hii slowtolearn,
Output for ps -ef |grep -i sql
Code: root 3655 1 0 Dec04 ? 00:00:00 /bin/sh /usr/bin/mysqld_safe
mysql 3691 3655 0 Dec04 ? 00:04:51 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --skip-locking --port=3306 --socket=/var/run/mysqld/mysqld.sock
root 3692 3655 0 Dec04 ? 00:00:00 logger -p daemon.err -t mysqld_safe -i -t mysqld
root 29280 29219 0 16:59 ttyp2 00:00:00 grep -i sql and when I type /etc/init.d/mysql start I get Code: Starting MySQL database server: mysqld...already running
I'm inclined to think that I've buggered up permissions somehow.... but my Linux knowledge is limited. The only thing that I can say I did was trying to 'remove' the Quote: new lirc_pvr_150 module as Jynxeh stated in post listed above.
I'm stumped.
BTW: Running R5D1 + 0.20 (see sig for hardware)

I may be barking up the wrong tree here, but did you say that after you went wireless, (and did other things) you lost your connection to the backend? You might want to make sure that your wireless router is not blocking access. most have a firewall built in.
just a suggestion.

I was just about to jump in there and say... "It's a single box. So, it's only connected wirelessly to the outside world via the router." But, I've just had a thought.... when getting my wireless up and running I ran netcardconf again, but ... I think I initially clicked on the wrong one.... I wonder, did that stop Myth talking to itself?
I'll have to investigate. don't know if this will knock out my connection here.

Well, it didn't work... but hopefully I'm tracking it a bit closer. It looks like it may be related to messing with lirc(?).
I reran mythtv-setup as a SU and below is the beginning and end of what was left on the screen once I'd exited it. BTW - it appears all the addresses and port numbers are correct.

You probably should modify the Master Server
settings in the setup program and set the
proper IP address.
As you can see here the problem is not being ablt to connect to the backend.
(Anyone seen that Eddie Izzard sketch where he's showing the moitor the printer? No? Anyway..)
Suggestions please!!!!!!!!!!

tophee,
It looks like you are connecting to the mysql database fine and it is using localhost which should be the 127.0.0.1 address. Also lirc would have nothing to do with your inability to connect to the backend.
Are you sure the backend is running?
ps -ef |grep backend
Also you may want to try and use strace to see where the problem is at a system call level:
strace -fq -o /tmp/strace.out mythfrontend
You should see in the strace where it is trying to connect to the socket and what it is actually failing with each time. If you are not experienced at reading strace it may not make much sense to you though.
Also do a netstat -an to see the status of the socket:
netstat -an |grep 6543
Also, do a ping of localhost and make sure it is pinging 127.0.0.1:
ping localhost

Along with what symcha suggested, you mentioned you had made some changes to your network config. Is lo still configured? Run "ifconfig -a" in an Xterm, you're looking for an entry such as:
Code: lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:56765 errors:0 dropped:0 overruns:0 frame:0
TX packets:56765 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:4059547 (3.8 MiB) TX bytes:4059547 (3.8 MiB) If not, check /etc/network/interfaces and see if you have lines similar to: Code: auto lo eth0
iface lo inet loopback
(Not necessarily exactly like that, but similar)

Hi results from the various things suggested:
ps -ef | grep backend
Quote: mythtv 4727 1 0 Dec05 ? 00:05:22 /usr/bin/mythbackend --daemon --logfile /var/log/mythtv/mythbackend.log --pidfile /var/run/mythtv/mythbackend.pid
root 30389 29825 0 13:19 ttyp2 00:00:00 grep backend strace -fq -o /tmp/strace.out mythfrontend Quote: bash: root@mythtv:/home/mythtv#: No such file or directory netstat -an | grep 6543 Quote: tcp 0 0 0.0.0.0:6543 0.0.0.0:* LISTEN ping localhost Quote: PING mythtv (127.0.0.1) 56(84) bytes of data and just waits to timeout.
I'll print out the results of slowtolearn's suggestions later

Also check your /etc/hosts file, should contain a line like
Code: 127.0.0.1 myth1 localhost
where "myth1" above would be your box's hostname.

Hi slowtolearn,
ifconfig -a gives me (plus stuff abouit ath0, wifi0 and sit0
Quote: lo Link encap:Local Loopback
LOOPBACK MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) My interfaces file looks like this, but should contain info on my wireless card (ath0) card - I'm sure it used to... Quote: # /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
# automatically added when upgrading
auto lo ath0 ath0 ath0 wifi0
iface lo inet loopback
iface wifi0 inet static
address 192.168.0.1
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.254 my /etc/hosts fie looks like this: Quote: 127.0.0.1 mythtv localhost
# The following lines are desirable for IPv6 capable hosts
# (added automatically by netbase upgrade)
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
I
Is there any record of the boot process? I think I saw a line about having problems opening the ~/network/interfaces file.
Regards
