RE: [Samba] Memory Leak in 2.2.6rc2??
Hi Jerry, i just pulled an all-nighter doing a re-org of all our servers which gave me an opportunity to clean things up. Thi ngs went well with once expection; A clean install of RedHat 7.3 + Samba 2.2.6 was an absolute fscking nightmare. I could join the domain, wbinfo showed groups and users properly, pam.d/samba, nsswitch.conf and smb.conf were configured identically with another samba server that runs great. What I ran into was: - getent would show only local groups - Win2k workstations connecting would only come in as nobody - shares would show up but double-clicking on a share would result in a login dialog. I started with pre2 and worked up to rc3. At some point things went really haywire and I got the looping getent you describe. In answer to your other questions: The domain is mixed mode. Winbind enum users and groups are explicitly specified Server in question is dual PIII No build options - straight from rpm. the one thing I do notice is a noticeable pause when loggin in or for any process requiring authentication (e.g. scp) SMB.CONF: # Global parameters [global] workgroup = AHBLNT1 netbios name = MILTON server string = MILTON File/Print/Web Server security = DOMAIN encrypt passwords = Yes password server = iman log file = /var/log/samba/%m.log max log size = 0 announce version = 4.0 socket options = TCP_NODELAY IPTOS_THROUGHPUT SO_RCVBUF=8192 SO_SNDBUF=8192 domain admin group = @DomainAdmins os level = 1 preferred master = False local master = No domain master = False dns proxy = No wins server = 10.0.10.8 winbind uid = 1-2 winbind gid = 1-2 winbind enum users = yes winbind enum groups = yes template shell = /bin/false winbind cache time = 10 winbind use default domain = Yes admin users = @DomainAdmins hosts allow = 10. 127. 142.173. max connections = 5000 printer admin = @DomainAdmins,root load printers = yes printing = cups print command = lpr.cups -r -P%p -o raw %s lpq command = lpstat -o %p lprm command = cancel.cups %p-%j large readwrite = yes name resolve order = wins bcast host utmp = yes [ers] comment = ERS Data path = /shares/ers admin users = @DomainUsers write list = @DomainUsers create mask = 0775 directory mask = 0775 force group =DomainUsers [printers] comment = All Printers path = /var/spool/samba printer admin = @DomainAdmins, root, repro printable = Yes browseable = No guest ok = yes [print$] comment = Win2K/NT Printer Drivers path = /etc/samba/drivers write list = @DomainAdmins, root, repro admin users = @DomainAdmins browseable = no read only = no [apps] comment = Standard AHBL Applications path = /shares/apps force group = DomainUsers read only = No create mask = 0777 directory mask = 0777 admin users = @DomainUsers write list = @DomainUsers nt acl support = yes [data] comment = AHBL Data path = /shares/data write list = @DomainUsers create mask = 0777 force group = DomainUsers directory mask = 0777 oplocks = false level2 oplocks = false [dexco] comment = Dexco force group = DomainUsers read only = No create mask = 0777 directory mask = 0777 admin users = @DomainUsers write list = @DomainUsers oplocks = false level2 oplocks = false path = /shares/dexco [imanage] comment = production documents browseable=no path = /shares/imanage write list = @DomainAdmins imanage -Original Message- From: Gerald (Jerry) Carter [mailto:[EMAIL PROTECTED]] Sent: Saturday, October 12, 2002 8:25 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: [Samba] Memory Leak in 2.2.6rc2??

Its at it again. Does rc3 address this? The only thing being done on this server right now is printing by one user.

We were running with pre2 for a couple of days without problems. H. Can you do a ps on the winbindd and let me know what the SIZE and RSS figures are ? Also, can you let me know more about your domain environment (how many trusted domains etc.).

RE: [Samba] Memory Leak in 2.2.6rc2??
Same thing with rc3. Browse to a share on the Samba server and winbindd and smbd go nuts. Winbindd takes 90% cpu and an smb daemon take upwards of 12MB. We'll backtrack to pre2 and see how things go. greg -Original Message- From: Gerald (Jerry) Carter [mailto:jerry;samba.org] Sent: Friday, October 11, 2002 3:11 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: RE: [Samba] Memory Leak in 2.2.6rc2??

[Samba] Memory Leak in 2.2.6rc2??
We upgraded to 2.2.6rc2 yesterday to continue our resolving of the printer driver problems. (Thanks Jerry Rohin) For unrelated reasons I wanted to log into the machine late last night and found Putty couldn't connect. When I get in this morning the server was completely hooped with Out of Memory errors on the screen with SMBD as the offending process. Trying to log into any console resulted in an instant lockup with the same error so I was forced to hard reboot. Anyone had any similar experience? Some relevant info: The server was not rebooted after upgrading to 2.2.6rc2 from Pre2, just the Samba services where re-started. HP's WebJetAdmin Daemon was running with over 20 instances. (Was 2 before). We've taken it off for now as we're not big enough to warrant that level of control.

RE: [Samba] Win2K Printer Driver Problems - Hi Jerry!!
OK, OK, got it now. Printer Admin is defined in the docs as a Share parameter, but to be able to modify server settings it needs to be in the Global section. I'm still getting 20+ print messages in the workstation's System Event log whenever a change to the server-based driver is made. Is this normal? Thanks much Jerry! Looks like our two-month nightmare is over.

If you are actually at 2.2.6pre2, the printing patches are already in and downgrading to 2.2.5 w/ jerry's printing patch isn't going to help (might hurt) Please test with 2.2.6rc2. Thanks. 9. On General tab, choose Printing Preferences - Basics and switch page layouts between portrait and landscape clicking OK in between to update the driver. - I assume at this point the driver Devmode is being set, correct? Correct, this executes the driver so you don't have a null devmode I think I've already mentioned this in anotehr post, but you need to do this on the Advanced tab to set the device mode on the server. The General tab sets the per user devmode on the client. You may need to install the driver on the server and click ok on the properties page, and then reopen before the Printing Preferences button shows up on the advanced tab. cheers, jerry - Hewlett-Packard http://www.hp.com SAMBA Team http://www.samba.org --http://www.plainjoe.org SAMS Teach Yourself Samba in 24 Hours 2ed.

RE: [Samba] GetPrinter Level 2 does not get devmode
9. On General tab, choose Printing Preferences - Basics and switch page layouts between portrait and landscape clicking OK in between to update the driver. - I assume at this point the driver Devmode is being set, correct? Ahh... The general tab is for the per user device mode. You must do this from the advanced tab to set it on the server. Hmm. All controls on the Advanced tab are greyed out, even for the administrator connecting as root. Is this related to being unable to delete drivers from the ssrver using Server Properties? This was mentioned as one of the 2.2.6rc2 fixes. Greg -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba
