Sysvol on GlusterFS?
Hi all, CTDB seems to be needing an underlaying GlusterFS. Would it be possible to declare a second GlusterFS share to host Sysvol data? I have no experience about distributed file systems, so I'm not sure this GlusterFS file system would act as a normal FS (modulo locking process) from Samba point of view when it access to that FS. Then...

Re: LPRng: Putting a stamp on all printed sheet
...iate parameters, including, I suppose, the right bounding box, the right location of the text, maybe change the fonts, get the user name and date and stuff. You will have to put this code on every page of your print jobs if you want it on every page. Of course, you can embellish this, and use fancy underlays and the like. The user name will be found with the set command in your printing shell. The printer name should be a constant, and date can be generated from the date command. Obviously, there are a lot of details to polish. Put this file after the Page: directive(s) in your postscript files, as...

[RFC PATCH net-next 12/12] vhost_net: batch submitting XDP buffers to underlayer sockets
This patch implements XDP batching for vhost_net with tun. This is done by batching XDP buffs in vhost and submit them when: - vhost_net can not build XDP buff (mostly because of the size of packet) - #batched exceeds the limitation (VHOST_NET_RX_BATCH). - tun accept a batch of XDP buff through msg_control and process them in a batch With this tun XDP can benefit from e.g batch transmission

[PATCH net-next 11/11] vhost_net: batch submitting XDP buffers to underlayer sockets
...them in an array and submit every 64 (VHOST_NET_BATCH) packets to the under layer sockets through msg_control of sendmsg(). When XDP is enabled on the TUN/TAP, TUN/TAP can process XDP inside a loop without caring GUP thus it can do batch map flushing. When XDP is not enabled or not supported, the underlayer socket need to build skb and pass it to network core. The batched packet submission allows us to do batching like netif_receive_skb_list() in the future. This saves lots of indirect calls for better cache utilization.

Files =>2GB"
Hello to the list, We have installed samba 3.0.12 on a solaris sparc server , mainly acting as a backup-server. Now the problem: Some user want to save whole disk-images on their shares which exceed the 2 GB limit. Now my question: Do i need to compile with option "-m64" , or is the underlaying FS responseable for a successful action Kind regards martin schreiber

How well ext3 will tolerate errors?
Hi! I would like to know how well ext3/(ext2) will tolerate underlaying errors (I am planning to use loop-AES backed ext3 fs). So if there is 1024 bytes corruption of data what will be the worst case: - If this data belongs to some file, this part of data(file) has been lost? - If this data belongs to superblock, I have to repair ext3 and use another superblo...

Active Directory clients in DMZ

I read the document at https://wiki.samba.org/index.php/OpenLDAP_as_proxy_to_AD#Authentication_against_AD_through_openLDAP_proxy and it tells about an OpenLDAP proxy to authenticate some external services through it, but I need to join some Windows clients so I think I

flow map lines between point pairs (latitude/longitude)
...10 -88.21597 37.09472 -89.13694 I am interested in plotting variable-width lines, based on NumberOfTrips, between point pairs (OriginLongitude,OriginLatitude) and (DestinationLongitude,DestinationLatititude), e.g. a flow map between the ports. At some point, I may wish to add an underlay base map (say counties in the US), but that is not critical at this time. There seem to be many packages in R that deal with spatial data (sp, maps, PBSMapping, etc.), but it is unclear to me which one would work best for this application. Any advice gratefully appreciated. R. Males Cincinnati,...
