<0> for multiple rotating backups
<0> but for now can't even get a simple rsync command to have the results I expect
<1> so write a shell script, perl script, python, ect that will run them
<0> I'm intending to re-use a script I found, that i like
<0> but it won't help me much if I can't get the basic command to work.
<1> okay, what problem you having with rsync and how are you innitiating it?
<0> rsync -avz -e ssh root@localhost:/var/www/ /var/www/
<1> okay thats not a good way to do it imo
<0> i'd expect that to mirror /var/www/ from the first machine to /var/www/ on the backup machine
<1> and why are you invoking ssh when its a localhost copy
<1> well first machine and second machine are the same thing in that example
<0> ok i'll try using local ip addresses then
<2> Did I mention I hate slackware?
<0> rsync -avz -e ssh root@192.168.0.5:/var/www/ /var/www/
<0> how do I specify that the second machine is 192.168.0.6 ?
<1> well if nothing is specified it is the local machine
<1> so that rsync would call 192.168.0.5 and pull /var/www/ and put that in local machine /var/www/
<1> if your going to automate the machine and its a lan i recommend a simple rsync configuration on the from box that will allow you to use rsync without piping thru ssh
<0> ssh is not necessary in the context of my lan ?
<1> why would it be?
<1> are you backing up sensitive data? is one of your local machines compromised and sniffing your network to capture said sensitive data and transmit it to someone else?
<0> don't know exactly, just felt that accessing a box using ssh was a best practice
<0> but now that you mention it, you're obviously right
<1> it is if your using a username and p***word
<1> but if you setup rsync you dont need a username or p***word
<1> it will allow access to specified ips to use rsync to copy data (or write it depending on the configuration)
<0> ok
<1> to automate ssh you would have to use null phrase ssh keys which is bad
<0> there's just another problem i've been running into i'd like to solve first
<0> I just tried to run :
<1> i would rate null phrase ssh keys a higher risk than plain ssh :)
<1> err than plain rsync on a lan
<0> rsync -avz /var/www/ root@192.168.0.6:/var/www/
<0> and i get my main problem with rysnc
<1> okay that would copy local machine to the 192.168.0.6
<0> tons of "read-only file" system erros
<0> errors
<0> yes,
<0> the main machine, yoruban, should be making backups to the backup machine, legba
<1> oh thats bad
<0> yoruban is .0.5
<1> and its not ssh or rsync issue
<0> legba is .0.6
<0> well I was reading that when you run rysnc daemonized
<0> then you have to have read-only=no in your rsyncd.conf
<1> see read only means the destination is mounted read only (easy to fix) or it has locked files on it which could imply a root kit
<1> yes if your going to write to it
<1> my recommendation is pull the data using the backup machine
<1> and do not allow writes to the active machine
<1> then if you need to do a restore you can use rsync -e ssh in a session to restore the data
<0> ok, so I'll try the same test from legba
<1> oh oh the format of your rsync -avz is wrong, you dont use root@192.168.0.6 thats an ssh pipe deal
<0> oh
<0> what should I be using then ?
<1> you would rsync -avz /var/www/ rsync://192.168.0.6/<rsync title>/var/www/
<1> and the rsync config would have to be set for write permissions
<0> but would this be for running rsync one-time, or daemonized
<0> ?
<1> personally i restore using rsync -e ssh and do backups with rsync -aq --delete rsync://system/<rsync title>/path/to/files
<1> the one using rsync:// is for talking to a daemonized system
<0> well in what I was reading I couldn't really tell if I needed to set it up daemonized
<0> what do you think ?
<3> Here's 30 cents. Go ask someone who cares.
<1> what i do is setup each server i'm backup up with rsync daemon
<1> and i pull the data using a script on my backup server to my terabyte drive
<1> then on the rare occasion that i have to restore something i log into the backup server and use rsync -e ssh to restore the data
<1> my backup server remains isolated from the world this way as nothing can push data to it and I can only ssh into it from specified ips
<1> my backup server is designed to drop all incoming packets it doesn't initiate except ssh on 2 ips
<1> everything else on ssh is ignored
<1> i believe in protecting my data :)
<0> so if i understand correctly you can't ssh to your backup server from the wan
<0> ?
<1> right
<1> only 2 ips on the net can ssh into the box
<1> if i need to restore data i log into the backup server and push the data back to the servers
<0> wait, how can you log into the backup server if you're not inside your lan ?|
<1> i use iptables to block all access to ssh except 2 ips, since i work remotely one of the ips is my ip here
<1> the other ip is a rotating ip of one of the boxes in our network as a back way in should i be unable to access from here or need to access it from somewhere else
<4> slm tunneling i gess
<1> kinda
<1> i can ssh in from here
<1> at my house
<1> or i can ssh in from the network box that has access to the server at this point in time, that rotates
<0> i get it
<0> sounds pretty good.
<0> and secure
<1> i have went to great lenghts to try and secure the network from any penetration cause i really hate script kiddies ... and i dont like to work hard
<1> if a box gets compromised i have to take a break from gaming and fix it hehe, if they can't get in i can keep gaming
<0> well that's a good incentive to have good security then, lol
<0> what command do you think I should use to do my test rsync and try to solve those read-only errors ?
<1> last compromise we had was probably better than 5 years ago on a 6.2 system which was on a migration path anyway
<1> slm first off dont use rsync daemon to write to your server
<1> setup rsync daemon only to read from your system
<1> then use a script on your backup system to pull the data
<0> i've understood I will run the command on the backup system
<0> but i think i have to do some test commands
<1> on the occasion that you have to restore dont use the daemon :)
<0> because of all the errors I get each time I try to use rsync
<1> show me the command your using that gives you errors
<0> I should get rsync daemon running on my backup server then ?
<1> no, you dont need it on your backup server
<1> your pulling with command line
<0> could you tell me what command I can run on the backup server to do a test, see if rsync can backup /var/www/ without errors ?
<0> (i'd be happily surprised...)
<5> whats the easy way to set a gateway for eth0 ? ifconfig eth0 LANip ?
<1> on backup run rsync -avz --delete rsync://192.168.0.5:/<rsync title>/var/www/ /var/www/
<1> OneWicked1 configure your system for the gateway and restart network services
<1> OneWicked1 what distro you using?
<5> debain ( shell only )
<1> the rsync title is the [name] you put in rsync.conf on the server
<1> OneWicked1 i think thats /etc/network but i'm rusty with debian
<0> don't have an rsync.conf
<1> you should have one on your server (not backup, the one your backing up)
<1> you should have a daemonized configuration on the server your copying from
<6> evening everyone, having some sound quality issues on my box, running FC4 with ALSA sound system with my wonderful on board Intel sound and i'm having some quality issues, i can't quite put my finger on it but it just sounds like garbage, almost like it's running in 22k instead of 44k or something, anyone have any clue what i can do to fix this ?
<0> it should be in /etc/ right ?
<7> OneWicked1 /etc/network/interfaces needs to be modified
<4> TheZuule: maybe it's kernel latency, what's your default scheduler ?
<6> drkwolf: couldn't tell ya, all i know is the sound is less than normal quality, not lagged just not what i would consider decent sound
<6> drkwolf: almost like it's 8 bit or reduced sampling rate
<0> redragon ?
<1> yes
<4> TheZuule: the sound quality doesn't degrade under heavy load ?
<6> drkwolf: no it's equally garbage in any app regardless of what's going on in the background :)
<0> I don't have rsync.conf
<0> it's not in /etc/
<0> should it be there or somewhere else ?
<1> you need to put it there
<6> i'm looking through the /etc/alsa folder configs but i'm not seeing anything except the dmix.conf file even mentioning a sampling rate and that's listed at 48k which should be okay i think
<1> unless you have an /etc/rsync
<1> its probably not there by default, you have to create it
<0> what options should I use ?
<0> I'm creating it on the main server right ?
<1> http://paste.getlinuxhelp.org/2608
<1> try that
<0> thanks am trying
<4> TheZuule: it seems like a driver problem (or a miss configuration )
<6> and somehow fedora loads up alsa without an /etc/init.d entry so i cannot reload the sound drivers without rebooting the machine, anytime i try to use modprobe it shows the modules as being locked even if no apps are using them
<8> i'm quite &?&?% rusty and just can't remember the line ... i just installed a full install of slackware 10.2 and no lilo or stuff like hat i made a boot disk during install when i boot and the disk loads i login as root and i just can't remember what to type to log onto graphical mode :p
<6> drkwolf: i just tried adjusting the rate in dmix.conf down from 48000 to 44100, brb let me see if that had any effect
<1> GaTeSS dont know much about snackware but try startx
<8> Redragon ok thanks ! :)
<9> noip2: /lib/libc.so.6: version `GLIBC_2.3' not found (required by noip2) <--- help
<0> redragon
<0> rsync -avz --delete rsync://192.168.0.5:/rsync.conf /home/jcmoussin/ /home/jcmoussin/
<0> rsync: failed to connect to 192.168.0.5: Connection refused (111)
<0> rsync error: error in socket IO (code 10) at clientserver.c(94)
<4> noip2: what's u distro ?
<9> e-smith
<1> no slm you need to create rsync.conf on the remote machine, if you used the example i pasted then it would be rsync -azv --delete rsync://192.168.0.5:/backup/home/jcmoussin/ /home/jcmoussin/
<6> WOOT i got it, oversampling for the loss
