From: Tom H. Lautenbacher on 2 Jul 2010 20:10 *SOLVED* Hello TMSIII, hello all Thank you all for all your help and advice that you provided me! I did analyze with sysinternals process related tools and saw that the system does absolutely nothing suspicious in the long "freeze-times". Everything seemed just idle and waiting for nothing. > maybe some antivirus interaction? > Will check with sysinternals but assume no, because oft he > locally-is-everything-fine thing. This was the hint that lead me directly to the problem. Although I had the same thought as TMIII ("can't be any software's fault, since it locally-everything-is-fine"), I took the idea of TMSIII and tried it out and deactivated the antivirus/firewall tool (Kaspersky Internet Security (KIS) 2010). Result: Everything worked like a charm! So the problem was the antivirus/firewall suite and not Samba, DNS or any other network daemon. Kaspersky support guided me to a setting in the firewall of KIS (set local network from "local network" to "trusted network"). Since then all programs start quickly as they should, even in the roaming profiles. For some reason this setting never affected local profiles but only roaming profiles. I do not know why. I did not try it out yet, but I expect that the very long creation times for new profiles has exactly the same cause, as the very long startup of first-time-launches of software. So I assume that this problem is gone now, too. So finally it was indeed a problem which had nothing at all to do with Samba, but only with general networking and firewalling. Thank you all!

But I've tried Samba 3.5.2, 3.5.3 and 3.5.3. Hey...that's something to try. Try the latest released version and see if you have the same symptoms/problems! I've not had these problems. (I don't call it a problem if someone with a 10GB profile has slow login logout times...anywho). But I typically place profiles on a mount that does not have ACL's turned on. More recently on ZFS volumes. Be interesting to see network traffic. TMS III But I am using both a Win7-64 and WinXP client to log into my PDC and generate continuous havoc. Just wait until you try using winbind to authenticate security on your linux PDC! Ha! Warning -- keep a rescue disk around in case you get locked out of your system! ;^] On top of roaming profiles, I used the group policy client to create roaming profiles for all clients -- even if they were not part of the domain! (this was when I was having problems joining my computers to the domain reliably). Anyway -- I have long logins on Win7 (~ 4-5 minutes, vs. about 20 seconds on XP). Where I get the real long pauses are on logout -- I've seen it finsh after 45 minutes one time -- the clients are communicating to the PDC but at speeds usually <100K/s. I know that it is not likely to be samba's fault in regards to the speed, since I get *up to* 100MB read/write to samba during benchmark testing. maybe some antivirus interaction? Will check with sysinternals but assume no, because oft he locally-is-everything-fine thing. the login/logouts -- read about them on MS's website...look up under profile loading ... it talks about how multi-gig profiles will really slow down first time loading. As I wrote, I am having the problem with FRESH CREATED profiles, which are just a few kilobytes of size! --- Ok -- that's just weird. No argument! If you think it is a network problem, use "wireshark" -- it will let you observe the network traffic. (google it) it's also free. Thank you Linda. You need to become familiar with all these diagnotic tools (that and get yourself a "procmail" email filter so you can filter out all the garbage from all the email groups you have to subscribe to to just keep things working!)... Do you know a good windows-alternative to procmail? Isn't the new outlook 2010 able to group emails into threads? ---- You can run all the linux utils -- including procmail under cygwin on windows. I missed all the linux utils so much -- I installed cygwin on windows 7 years ago and haven't done without it since! You can even run a local IMAP server on your windows box -- let your windows box download all your email from your ISP -- then connect to the local server with Outlook or Thunderbird and use IMAP. OR -- better -- use your server as an email server as well! My server downloads my email from my ISP (see linux util 'fetchmail'), then it calls my filter script (or it could call procmail). It also calls spamassassin before it tries to deliver it to me. But then my filter script (like procmail only different!) sorts the emails into folders in my home directory on the linux server under 'mail'. I then use 'dovecot' (an very fast, secure IMAP server) to serve my email to my windows clients. Since I have multiple machines, I don't want the email coming to one of the windows machines. It stays on the server in my home directory. I have well over 100 file folders -- only about 70 of them actively receive email (some are just archives/sorting bins). But in my clients I see all the folders by email list -- I read them when I have time -- so I don't get interrupts. I think you'll find it's better to leave the email on the server -- that way if you can try differnt clients (I can switch between outlook and tbird if I was so perverse). Both will read my active mail. Groups that have new messages in Tbird light up in blue. Seriously -- I have nearly 80 email groups I sub to...if I didn't filter I'd just 'lose it'...but they all go into folders and I read them when I want...if I don't, I have them setup to automatically expire after a few months... it's just like a forum, but better....since it's all in one place! :-) Well I am attending to about 20 forums and I am having everything in one place too: My email-mailbox as soon as I am getting an answer to my postings :-) But not 10000 other emails that need further processing ;-) ---- But you can't keep track of the 20-80 forums when you want -- in your email client -- you have to find the websites for each of them. And just now (and day before yesterday). when I wanted to respond to someone in forums (I read forums too -- no choice for some groups) -- I have to 'sign up', but then I get told that my message is going to be moderated because I don't post enough -- so then I have to wonder if my post will even see the light of day. It's a real pain. But that's getting to be an old topic .... Check out 'wireshark' and the sysinternals utils like 'procmon' and 'process explorer'. Procmon will let you monitor processes -- wireshark can let you see if your client is waiting for network messages... If you know the linux utils, cygwin is a complete set -- I use it's 'X' server all the time to display utils from my linux box so I can monitor things. Cygwin will make use of the 'unix extensions' in samba if they are enabled, BTW... -linda -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba
