Amanda user
If I want to change my amanda user (I have a good reason), am I right in thinking all I have to do is change the user in the amanda.conf of every config and change the user in inetd.conf and restart it on the server and every client? Or do I have to recompile amanda with the new user specified? - David Flood Systems Administrator [EMAIL PROTECTED] Tel: +44 (0)1224 262721 The Robert Gordon University School of Computing St. Andrews Street Aberdeen -
Repost: How to use Amanda through bidirectional firewall?
[Reposted from 2 Apr 2002] http://amanda.sourceforge.net/fom-serve/cache/139.html wrote: Amanda from behind a firewall Running an Amanda server from behind a firewall, to clients outside it, can be a bit tricky. Amanda uses quite a few ports for communications. The general sequence is: 1) The server makes a start backup request on port 10080 to the client. 2) The client forks an amandad process, which then attempts to contact the server on a random udp port. 3) The server opens 2 or 3 random TCP sockets back to the client per dumper process. (one for data, one for messages and one for index, if indexing is enabled.) 4) data starts shuffling. The problem with a firewall is step 2. Since most firewalls are set up to allow any outgoing traffic, the others steps usually have no problems. But that random UDP port back in to the server is usually blocked. This causes a symptom of timeout waiting ack in /tmp/amanda/amandad.debug on the client. ... You can also use the connection tracking feature of the new linux 2.4 firewall code. This will eliminate the need to open incoming ports on the firewall. [EMAIL PROTECTED] Hi everyone, I would like to run the stock Red Hat 7.2 Amanda build on machines where both the client and server run a firewall. To do this, i think i'm going to need connection tracking. :-) Is there any documentation available on using netfilter connection tracking with Amanda? I found this thread on the netfilter developers list: http://lists.samba.org/pipermail/netfilter-devel/2001-May/001263.html It's nearly a year old, and there was no resolution at the time. Has anyone got it working? Paul http://paulgear.webhop.net
Re: Unloading tapes when task done ?
Its sorta like when you go to your kar mechanic. The job is not complete till you put all of your tools away, and cleaned your work area for the next job. That would be the mechanics responsibility, and not the cleaning staff that follows in the evening. But at this moment, some 18hours after amanda started, it is still going, and only on the third ( of an estimated 6 tape backup ). So the unload/eject is the least of my current concerns with regard to getting a backup to happen. Right now the most efficient system i have would be to run tar cMf remoteHost:/dev/st0 / directly on the remote system. after each EOT i will run a shell script to change to the next tape. AFTER I DO THIS CORRECTLY, only then will I get a TRUE feel of the time needed to do this phase of the task. /gat John R. Jackson wrote: Maybe they can OPT-OUT of the feature ... It's just as easy for someone to opt-in and do their own tape operations when Amanda is done. Amanda will currently support both camps -- unload it when done vs. leave it alone. Why add more complexity? We already have too many options (and lots of other things on the TODO list). btw, what do u mean each operation. ... I meant amdump and amflush. John R.

Re: sendbackup with dumplevel 0 takes a while to startup :-{
Problem with this is obtaining a definitive PROOF. you do the amanda process, and you notice that the tape is not spinning, even though you are in the sendbackup phase. You notice that the ethernet switch is not blinking. You can also notice the task(s) that are running. You also notice that the disk controller light is light. You can make some general conclusions, like gee the reason i up'ed the destimate value from 30min to 6hours is due to what is occuring now. I dont know why, or all of the facts, but i do notice thats it's idle. and i do notice transfer timeouts, although i dont know why exactly either - yet. /gat John R. Jackson wrote: according to the tar docs, the --listed-incremental will check on the files listed in the file if the incremental file is not empty. I suppose the listed-incremental file got filled during the sendsize proceedure?! No. It got filled by the previous sendbackup run (e.g. yesterday). And, FYI, for a level 0 (full) dump, the listed incremental file comes from /dev/null, i.e. it is used, but empty. During the sendbackup step, tar is apparently going through and checking the list, as no data is being transmitted while tar is doing this check. I'm not sure exactly how tar does this. You'd have to look at their code or ask them. I'd be surprised if it completely lost it for 30 minutes, though. Is this how its suppose to work for a level 0 dump? ( 4 hours (wall-time) sendsize, ~4hours (wall-time) incremental check, and finally the transfer of the data ( i suppose longer that 4 hours )) ... Probably true. Is this how it will work with other level dumps ( with the exception of the transfer of data step) ? Yes. Except Amanda may also request a third estimate one level higher than the previous one if it might be time to bump (you can control this with the bump* parameters). You might want to consider using an alternate size calculation tool called calcsize. It's not well supported, and does not handle exclusion lists, but does all the estimates at the same time so you might gain quite a bit of time that way. If you want to go this route, let me know and I'll find the postings from a while back about turning it back on. /gat John R. Jackson, Technical Software Specialist, [EMAIL PROTECTED]

problems with GNUTAR exclude-lists
I'm trying to configure an amanda server/client to use GNUTAR with exclude
lists. GNUTAR works great, but the excludes don't!
The basic configuration is like this:
define dumptype global {
comment Global definitions
index yes
compress client best
#maxdump 2
holdingdisk true
record yes
}
define dumptype bugs {
global
comment Backup incremental, remoto, comp best
holdingdisk yes
program GNUTAR
priority medium
exclude list /usr/local/etc/amanda/exclude.gtar
compress client best
dumpcycle 5
}
And the disklist contains this:
bugs /space bugs -1 hme0
in bugs I have the file /usr/local/etc/amanda/exclude.gtar:
martin@bugs:~ cat /usr/local/etc/amanda/exclude.gtar
./pruebas/
./amanda/
martin@bugs:~
But it's not excluding those 2 directories, and the problem is that the dumps
are growing to big.
What can be wrong?

Re: Unloading tapes when task done ?
DLT's are not flying head technology. They are like 9trk, QIC, i think travan, colorado. The heads do not spin ( i had to think about it ), as the heads move up down to change tracks. But the DLT 8000, now, also place the heads at an angle to tape direction, as well as going up and down. I dont even think there is an idler pully, just a tach. I'd like to know if there is 'continual' tension on the tape while it is loaded ( on a dlt )( Like that of a DEC Tape, or 9trk ) but I do not know. But for whatever technology reasons the schemes that tape mechanisms have evolved, they all rely on knowing what 'state' that they are in. When you have a power outage, turn off the drive, lightning, whatever, you may find that the tape left inside the mechanism to be of little use to you.

nfs mounting the filesytem isn't a problem, this is what i was going to do if what i was trying to do with the index server didn't work. the wierd thing about the hang is the only thing that changed was specifying an index-server other then the tape server. the dumps where written to tape, the index's where written but where still viewed as a temp file, they hadn't been moved to the file index. after seeing this i went back and reconfigured, recompiled, installed, and re-ran the dump and everything ran great. wierd behavior, but everything is running great now. thanks John R.

It also has a number of error handling issues. Any chance your other machine could NFS export where you want to store the index files to the tape server machine so it could write them that way? I used to do a variation of that. None of this has anything to do with your hang.

Re: A few interesting problems (tapeless, interactive restores, etc)
Hi John, I am looking at amanda-2.4.3b3, but aside from docs/VTAPE-API I don't see any mention of how the virtual tapes can be set up with AMANDA. And the VTAPE-API looks to me, as a non-coder, like possibly more than I need to know (though if i need to hack some C code I can). This sounds like it would be much easier for me, as having a virtual tape name to ask of ADSM is much easier than trying to figure out which tapes I need on my own, and restoring a dump disk for the purpose. Can you point me to any documentation, crude or otherwise, describing this process? If anyone else has gotten this to work, what does it involve? If I need to change tapeio.c, use special amanda.conf directives, etc etc etc (nothing is mentioned in sample files). I appreciate any assistance. Greg On Wed, 2002-04-03 at 22:39, John R.

Sounds like a perfect setup for the tapeio code in 2.4.3 (now in beta test, but the tapeio stuff has been stable for a long time). You would set up a disk area to emulate a tape, then use the chg-multi tape changer to move the data back and forth with your ADSM system. The current (2.4.3 beta) chg-multi has a posteject hook to a script you provide that could move the date into ADSM. It would be easy to add a preload step to do the other direction (don't know why I didn't think of doing that when I did posteject).

Amanda would tell you you needed tapes A, B and C, which would map directly to your ADSM areas. If you don't go with tapeio, then I think amadmin config find ... is what you'll want. You may also need to be a bit sneaky about the data motion to ADSM and leave the names and holding disk directories behind, but truncate the files to zero length, or, worst case, truncate them to just their 32 KByte header.

Re: Mysql backup
We are using a perl script that connects to remote machines and creates
a dump to the localmachine. A shell script that uses this perl script
is added to the crontab and run nightly. You can then use amanda to
backup these dumps. I've attached these scripts. Just edit the shell
to your liking and create the folder you want the dumps saved. Oh, and
the shell script is setup to delete any dumps older than 60 days.
Hope this helps. It's simple and reliable.

The kickstart config file works wonders when rebuilding. That will get the bare metal install then use Amanda to restore the data. Works for me but I would like to hear from others on this. hth, Lewis Watson __ Do You Yahoo!? Yahoo! Tax Center - online filing with TurboTax http://taxes.yahoo.com/
Amanda and Firewalls.
Hi Amanda Users, I have a question, I would like to use Amanda on servers that we have outside our firewall. Is there anyway, to get Amanda to work without opening ports on the firewall? Such as using SSH or some other way, or will Amanda work with only using ports open through the firewall? I have read the FAQs on the Amanda site, and I don't understand why there has to be a range of UDP ports open. Would it work with just using one UDP port, instead of opening a range of UDP ports? Maybe someone could explain how and why, and which ports I should open on the firewall. Thanks! Ward.
Re: I know this message... help restore entire system THANKS
On redhat 7.2 it should be in /root named anaconda-ks.cfg I think you need to copy this over to a floppy and rename it ks.cfg. When you place the rh 7.2 install disc in and it comes up with the install menu you type in linux: something-something and it will make an install just like you had on the machine where the kickstart file came from. I will try to find the something something line, take a look at www.linuxdoc.org hth, Lewis Watson - Original Message - From: Mr Igor Vertiletsky [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, April 04, 2002 3:19 PM Subject: Re: I know this message... help restore entire system THANKS Thanks for all the info. Of course the solution of restoring to the second drive bfore the 1st one fails is simply ingenius. BTW, what is kickstart config file? Could just point me in the right direction. It's just that this machine is an old pentiom 100 box. It does not do much, except firewall, router, DNS, and other crucial functions, so I would like to be able to restore it as quickly as possible. Thanks again for all the help. Igor. --- Lewis Watson [EMAIL PROTECTED] wrote: - Original Message - From: John R.

While I'm sure JJ and other lurking can confirm the true details, I believe that the clients start sending back udp packets to the server like so (from one of my client sendbackup files): sendbackup: stream_server: waiting for connection: 0.0.0.0.729 sendbackup: stream_server: waiting for connection: 0.0.0.0.730 sendbackup: stream_server: waiting for connection: 0.0.0.0.731 waiting for connect on 729, then 730, then 731 sendbackup: stream_accept: connection from firewall.719 sendbackup: stream_accept: connection from firewall.720 sendbackup: stream_accept: connection from firewall.721 got all connections Since ssh is a tcp connection, I don't see anyway to have Amanda use that as the transport device because of how it was designed to use udp for speed/etc. If you compile Amanda to restrict the tcp/udp portranges, it won't open up anything on your firewall that the public can see, it's more that your firewall is configured to pass such connections on to the clients and vice-versa. -- ~ Doug Silver Network Manager Quantified Systems, Inc ~
Problem with index files
hi, I have a problem with my index files. Each run, a gzip'd index file is created. Each run, this file is about 20 bytes long. I doubt gzip is compressing the information on 20+GB of files into 20 bytes... :-( Looking at the sendbackup.*.log files, I can see where the index program is invoked. I don't see anything to indicate _why_ the index files are so small. The amanda.conf has a global config with index yes which is used with all the dumptypes I have. amadmin reports v2.4.2p2. I'm running a RH7.2 Linux box, x86. GNU tar, gzip are in the right places. GNU gzip is v1.3 --- is that the right version? GNU tar is v1.13.19; what else should I look for/at to diagnose this? I'd like to know how to restore index files from tape, if anyone knows how to do that... Any help appreciated. -Adam -- Adam Lins www.bdti.com Engineering Manager Ph:(510) 665-1600 Berkeley Design Technology, Inc Fx:(510) 665-1680 Berkeley, CA 94704
