Re: Failure on W2k client
Hi folks, Both amanda:sendsize and smbclient are OK, it is the interaction that is the problem. This started with my question re: read_socket_with_timeout errors in sendsize.debug. The error is generated from lib/util_sock.c in samba code. From the logs smbclient is noting a failed open to amanda:sendsize. Smbclient takes it own error message as an indicator to use the next address resolution scheme and continues to attempt to connect. Sendsize has noted the socket open failure and declared "session setup failed: code 0"; since the smbclient process hasn't died yet, sendsize continues to log information from the smbclient it spawned. A few things could happen here. Sendsize could kill and respawn an error-reporting smbclient, or wait to call the session off until smbclient exits; Smbclient could march through the host resolution options before reporting a failed open, thus not confusing amanda:sendsize. The reason, probably, that a "wins" first host lookup works for is that the smbclient file descriptor is not a socket and a different set of routines are used to perform the open, which for what ever reason are more robust or less verbose, thereby not causing sendsize to make determination that the session failed. We have a choice of where to make the fix. Changing amanda:sendsize to wait for smbclient to exit before declaring a failed session would make amanda more robust; changing smbclient to wait until the full gamut of host resolution options have been tried before reporting errors would also fix this problem from an amanda perspective but may cause other smb-dependent apps to suffer. Having amanda handle the different possiblities smbclient presents seems a good way to go.. Does anyone careto look at the code? sendsize.c line 504, maybe... We have a tentative thesis that the initial problem may be caused by the NIC being put to sleep in "powersaving" mode during inactive times (night) which is why we can't re-produce the problem during the day. We did uncheck the bit that does this in the 3Com w2k driver but didn't reboot the system. We saw no change last night so we'll try rebooting the sucker this afternoon. thanks, hurf -- Todd Pfaff wrote: Ok, I think finally understand what Marty is trying to say. Marty, there are many people on this list who have been using samba for years and understand it very well and how it interacts with amanda, and if we couldn't understand the gist of your initial question, don't blame our lack of understanding of the english language. :-) Marty says his samba setup works, but because of the fallback from wins to broadcast the lookup takes longer than amanda is willing to wait. Amanda times out and as far as amanda is concerned, smbclient failed. I'm not even sure what the implications of this are or how to make it work more efficiently, I'm just interpreting what he stated. Marty, is this correct? Now, this said, I still think the problem is with samba. You should 'fix' your samba setup so that it doesn't take so long to do a lookup. Todd On Wed, 4 Apr 2001, David Lloyd wrote: Marty!

You obviously cannot understand what I am saying, or you have not followed this thread. If you cannot understand English I will have this translated into any other language that I have a character set for: SMBCLIENT CAN CONTACT MY WINDOWS 2000 SERVER. IT DOES NOT FAIL. IT WORKS VIA BROADCAST AND AMANDA FAILS TO SEE THAT IT WORKS. Or to reword this: SAMBA IS ABLE TO CONTACT MY WINDOWS 2000 SERVER; SMBCLIENT CAN CONTACT IT. HOWEVER, IT DOES THIS VIA BROADCAST AND AMANDA FAILS. As far as I'm concerned SMB is working correctly. It is setup to use wins, wins fails and it therefore contacts my Windows 2000 server by broadcast and connects. Perfectly. So how is it smbclient's fault when smbclient works? I can't understand your English...

Failure on W2k client
Hi Folks, Backing up shared folders (not full disk) a PC (Dell 420 dual 1ghz/W2k/sp1/15k-rpm UW scsi), we are getting this intermittent error: herman//rodney/workII lev 0 FAILED [disk //rodney/workII offline on herman?] "herman" is the amanda system ( FreeBSD 4.2-STABLE/"Amanda-2.4.2"/smbclient 2.0.7 ) this seems to be initiated by an error in sendsize (from sendsize.debug) sendsize: argument list: "smbclient" "\\rodney\workII" "-d" "0"\ "-U" "backup_user%secret" "-E" "-W" "PC-GROUP" "-c" "archive 0;recurse;du" added interface ip=128.84.247.9 bcast=128.84.247.255 nmask=255.255.255.0 added interface ip=128.84.247.9 bcast=128.84.247.255 nmask=255.255.255.0 added interface ip=128.84.247.9 bcast=128.84.247.255 nmask=255.255.255.0 added interface ip=128.84.247.9 bcast=128.84.247.255 nmask=255.255.255.0 read_socket_with_timeout: timeout read. read error = Connection reset by peer. session setup failed: code 0 The multiple "added interface" messages we don't see in any successful transactions. . Repeatedly running smbclient by hand: `smbclient '\\rodney\workII' -U backup_user%secret -d 0 -E -W DOMAIN -c 'archive 0;recurse;du' we see only single interface messages, no errors or timeouts. We do notice that the response is instantaneous. Is it possible that the quick response is confusing sendsize? We are backing up other NT and W2k clients successfully and only see this error on this client. any help appreciated. thanks, hurf Hurf Sheldon Dir.

ERRDOS smbclient returns 1 problem
Hi, We are having consistient problems* with a particular user's data. We've had the same problem on two very different machines (both Dell, one NT4.0/sp6, the other W2K/sp1 ) - we've checked out and changed network cables and path to the system - I did see in the archives a similar problem which had to do with large files and some settings in the network interface. The data does include some large (50mb) Power Point files (ppt). We would appreciate any suggestions including diagnostic procedures. thanks, hurf *representative error posts ?

I think you're asking the wrong group. This is clearly a Samba issue and you need to be asking them (or searching their archives), not the Amanda group. Someone on the Amanda group may know the answer because they just happen to also know Samba, but asking the Samba group has got to have a better chance of success. ...

A list of implementation questions
Hi Folks, Our amanda was set up by set up by someone who has moved on. I feel like I have a pretty good handle on it after 6mos. It has worked reliably. I've learned to add/delete disks, manipulate some of the config options and have succcessfully "twinned" our master configuration so I can test migration of our tape device from one platform to another as well as change the config for a different tape device. As time has passed our needs have progressed and I'm unsure of the best way to proceed. I also have some questions re: day to day operations. Our present setup is Amanda-2.4.2-19990920 on an HPUX 10.2 system backing up a heterogeneous environment of NT, Irix, FreeBSD and HPUX systems to an Overland 4000LX 15tape/1drive DLT. We are backing up the NT systems via Samba. Changes needed: 1: Move the drive to a PC based system - right now we have a FreeBSD 4.2-Stable system on a dual 266mhz P-II ASUS P2B-D mother board and an Adaptec 2930CU SCSI adapter. 2: Add backup for a Dell PowerVault 705 NAS device and Windows 2000 systems 3: Do archival backups 3a: use a second magazine 4: resolve authentication error Related questions: 1: When we move the Overland to the FreeBSD PC and run amlabel, we get errors in the system log file and the DLT goes out to lunch - we setup an HP SureStore 2300 6 tape DDS as a test and saw some similar errors but after the tapes were labeled they subsided: (ch0:ahc0:0:0:1): MOVE MEDIUM. CDB: a5 20 0 0 0 3 0 1 0 0 0 0 (ch0:ahc0:0:0:1): ILLEGAL REQUEST asc:3b,d (ch0:ahc0:0:0:1): Medium destination element full ch: warning: could not map element source address 0d to a valid element type (sa0:ahc0:0:0:0): tape is now frozen- use an OFFLINE, REWIND or MTEOM command to clear this state. Neither the FreeBSD list nor Overland has had any insight into this... 2: We can't directly access the NAS disks - how would we give dump instructions to a system that has it mounted via NFS or SMB? I thought Amanda used tar on Unix but a dump request to an Irix system with the NAS mounted failed "disk /remote/nas01/2 offline on nimble". A remote SMB mount can't be in turn shared so when trying to backup via smbclient we get: "PC SHARE //lassiter/N access error: host down or invalid password?" 3: How can we configure amanda to do only level 0 or only incremental backups? We'd like to (say) run level 0 over the weekend to one tape set and incrementals to another, with an eye to adding a second tape machine and do level 0 to one and incrementals to the other. 3a: To use a second 15 tape magazine, is there a way to setup amanda.conf to count all 30 tapes sequentially? The problem seems to be that Amanda thinks there is 30 slots if there are 30 tapes, so the chio routines fail. We'd like to have it stop the tapers, ask for the next magazine and start at slot 1 again. 4: We compiled the latest Amanda for FreeBSD (VERSION="Amanda-2.4.2") which included patches for Windows 2000 via smbclient - that works fine now. We are getting "auth" errors on the cd /usr/local/amanda/FreeBSD system that we built as the tape server: " ERROR: vermeer: [access as backup not allowed from [EMAIL PROTECTED]]\ amandahostsauth failed " - Did we miss something - I'm not able to track this down. 5: What other Amanda guidance/support resources are available? 6: Just out of curiosity, is anyone working on a gui configuration interface for Amanda? my apologies for the "laundry list" thanks in advance for any help hurf Hurf Sheldon, Dir.
