fetchmail and MS Exchange 2010
by Mark Rogers 05 Oct '10

05 Oct '10

I can't persuade fetchmail to collect mail from an Exchange server on our LAN (fetchmail and Exchange are both on the LAN). The errors I am getting are: fetchmail: Server CommonName mismatch: myoffice.mydomain.co.uk != 192.168.11.10 fetchmail: Server certificate verification error: unable to get local issuer certificate fetchmail: Server certificate verification error: certificate not trusted fetchmail: Server certificate verification error: unable to verify the first certificate fetchmail: Error exchanging credentials fetchmail: Authorisation failure on user(a)192.168.11.10 fetchmail: Query status=3 (AUTHFAIL) myoffice.mydomain.co.uk resolves to the office's external IP address, although I think (from Googling) that the first line is a warning not the reason for the failure. My fetchmailrc is fairly simple: set daemon 60 set invisible set no bouncemail set no syslog set logfile /var/log/fetchmail.log poll 192.168.11.10 protocol pop3 username "user" password "password" mda "/usr/bin/rt-mailgate --queue general --action correspond --url http://localhost/rt/" no keep You'll see from the last line that I'm trying to set up Request Tracker (RT), and it needs to be able to collect mail from our office mailserver. This guy seems to have the fix: http://berqnet.blogspot.com/2009/11/exchange-2007-fetchmail.html .. but I don't know what he means by "the fingerprint of the Exchange 2007". [We've had nothing but problems like this since moving to Exchange, but it does a reasonable job of keeping Windows users in check so we're stuck with it.] -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Scanner woe
by Bev Nicolson 04 Oct '10

04 Oct '10

I've taken charge of my first scanner (a freebie from a friend) but I'm having trouble getting it installed. If I go to XSane it says "failed to open device snapscan :libusb:001:002 " . I have since installed every XSane extra there was via synaptic but it's still won't play ball. I'm very reluctant to give in though so how do I investigate what's up? And even more to the point, how do I fix it? It knows it's there I'm sure. [Ubuntu 8.04] Bev.

Problem playing AVI files, they don't play, just stick at first frame
by Chris G 02 Oct '10

02 Oct '10

I seem to have broken something on my system, I'm sure AVI files *used* to play OK. When I try opening them with either mplayer or with totem they just show me the first frame and that's it. With totem I can drag the time slider across and the movie plays so decoding would seem to be OK, it's just that it doesn't play automatically. Any ideas what might be wrong anyone? -- Chris Green

Unsetting bits using sed or similar?
by Mark Rogers 01 Oct '10

01 Oct '10

Help! I need to go through a text file, and for all lines similar to this: X-Mozilla-Status: 0009 .. I need to unset the 4th bit (so the above becomes 0001). Not all X-Mozilla-Status: lines which have the bit set have status 0009, however. I have 0008, 000b, 0018, and so on. Suggestions? Background: Somehow I managed to delete a load of email in Thunderbird which I need. It ended up in Trash so I moved it back to my Inbox, but for some reason it didn't appear in my Inbox, but did get deleted out of Trash. However by "deleted" I mean it set the 4th bit of the status word, so until I compact the folder I can recover it by unsetting that bit. I still need to work out why it didn't go back into my Inbox, I think I may have discovered a bug there. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Change of email address
by ted.harding＠wlandres.net 30 Sep '10

30 Sep '10

Sending this for the benefit of any you who may have my existing email address (ted.harding(a)manchester.ac.uk) in their address-books. Apologies to all others to whom this may be irrelevant! Since Manchester University seem to have decided that retired persons no longer contributing to research in a Department shall no longer keep their email accounts, my existing email address will cease to function shortly. I have set up a new email address which is: ted.harding(a)wlandres.net (Ted Harding) The existing one (ted.harding(a)manchester.ac.uk) will still work for a week or two (possibly longer). If you have my existing email address in your addressbook, please update it to the new one. This message is being sent from the new address, so you may simply be able to derive the new entry directly from that (using some "add to address book" function). Thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <ted.harding(a)wlandres.net> Fax-to-email: +44 (0)870 094 0861 Date: 30-Sep-10 Time: 19:14:49 ------------------------------ XFMail ------------------------------

Nvidia driver custom refresh rate
by John Woodard 28 Sep '10

28 Sep '10

Hi All, I'm normally pretty adept at figuring things out but this one has me stumped. Googling has sent me down many alleys most of them blind. I have 2 identical machines one with Ubuntu 10.04 the other with Windows 7 Ultimate. The run through a KVM switch to the same monitor using their on-board Nvidia Geforce 6100 graphics adapters. The monitor is a cheapo AOC 24" TFT panel which is adequate for my purposes, mainly general office stuff, accounting, surfing, email etc. This monitor is weird in that it requires a refresh rate of 61Hz rather than a standard 60Hz to give a steady display at its native resolution 1920x1200. In the Nvidia control panel in Windows it is easy to set a custom refresh rate, so no problem and a nice display. Ubuntu 10.04 however using the current proprietary driver from the Ubuntu repositories does not have the same facility, unusable display so dropping back to a non native resolution for the monitor is the only way to use the GUI. Back in the day you used to be able to hack your /etc/X11/xorg.conf file and insert a new modeline to facilitate this but as far as I can tell this has no effect with the current incarnation of the Xorg server. I suspect the monitor is not outputting its configuration, data or something. I have removed the KVM switch and the problem still remains so it isn't that blocking the data from the monitor reaching the driver. Can anybody enlighten me on how to manualy do this and get the proper 1920x1200 resolution working @ 61Hz rather than the sole 60Hz option allowed by the Nvidia control panel? Cheers, BJ

Xmodmap Help
by Krishna Birth 24 Sep '10

24 Sep '10

Firstly please note that all k / K letters on this posting are altered to क / क (spiritual reasons.) I am sorry to thrust this project to you (mailing list). I am looकing for advice or if you have the time to construct a कeyboard mapping. There seems to be some problem regarding "if you assign Mode_switch and ISO_Level3_Shift to different keys, you can assign up to six characters to one key!" see http://tr.opensuse.org/SDB:Using_the_Extra_Keys_on_the_Keyboard The diacritics are usually typed with non-diacritic letter. It would be nice to have facility to use both in convenient way e.g. toggling with a Fonts / Scripts कey by permanently turning the Caps Locक to a Fonts / Scripts कey. Could this be done - When this Fonts / Scripts कey is pressed with a letter कey it toggles to diacritic letter 1 or 2 or 3 (depending on how many diacritics are there connected with a 'target' letter) - this toggling will need to factor in a 'remain at same spot' and toggle these diacritics feature. When the Fonts / Scripts कey is released then the cursor would move to the next base. Here are the target letters, the diacritics connected with them and the URL with more info about them: A Ā = http://www.fileformat.info/info/unicode/char/0100/index.htm a ā = http://www.fileformat.info/info/unicode/char/101/index.htm D Ḍ = http://www.fileformat.info/info/unicode/char/1e0c/index.htm d ḍ = http://www.fileformat.info/info/unicode/char/1e0d/index.htm H Ḥ = http://www.fileformat.info/info/unicode/char/1e24/index.htm h ḥ = http://www.fileformat.info/info/unicode/char/1e25/index.htm I Ī = http://www.fileformat.info/info/unicode/char/12a/index.htm i ī = http://www.fileformat.info/info/unicode/char/12b/index.htm L Ḷ = http://www.fileformat.info/info/unicode/char/1e36/index.htm l ḷ = http://www.fileformat.info/info/unicode/char/1e37/index.htm L L̐ = http://pastehtml.com/view/1az9crq.html - http://bit.ly/doq30H l l̐ = http://pastehtml.com/view/1az92sb.html - http://bit.ly/chipOw M Ṁ ̇= http://www.fileformat.info/info/unicode/char/1e40/index.htm m ṁ = http://www.fileformat.info/info/unicode/char/1e41/index.htm N Ñ = http://www.fileformat.info/info/unicode/char/d1/index.htm n ñ = http://www.fileformat.info/info/unicode/char/f1/index.htm N Ṇ = http://www.fileformat.info/info/unicode/char/1e46/index.htm n ṇ = http://www.fileformat.info/info/unicode/char/1e47/index.htm N Ṅ = http://www.fileformat.info/info/unicode/char/1e44/index.htm n ṅ = http://www.fileformat.info/info/unicode/char/1e45/index.htm R Ṛ = http://www.fileformat.info/info/unicode/char/1e5a/index.htm r ṛ = http://www.fileformat.info/info/unicode/char/1e5b/index.htm R Ṝ = http://www.fileformat.info/info/unicode/char/1e5c/index.htm r ṝ = http://www.fileformat.info/info/unicode/char/1e5d/index.htm S Ṣ = http://www.fileformat.info/info/unicode/char/1e62/index.htm s ṣ = http://www.fileformat.info/info/unicode/char/1e63/index.htm S Ś = http://www.fileformat.info/info/unicode/char/15a/index.htm s ś = http://www.fileformat.info/info/unicode/char/15b/index.htm T Ṭ = http://www.fileformat.info/info/unicode/char/1e6c/index.htm t ṭ = http://www.fileformat.info/info/unicode/char/1e6d/index.htm U Ū = http://www.fileformat.info/info/unicode/char/016a/index.htm u ū = http://www.fileformat.info/info/unicode/char/16b/index.htm Referring to the above 32 diacritics, in theory a diacritic letter could have up to 7 diacritics 'sign' variations per letter: 1. Macron 2. Dot Below 3. Candrabindu 4. Dot Above 5. Tilde 6. Dot Below & Macron 7. Acute and 2 diacritics 'case' (lower/upper sizes) variations per letter - in 'total' up to 14 diacritics variations altogether per letter In actuality, the maximum letter n/N has 6 diacritics sign/case variations and a/A only has 2 diacritics sign/case variations. Thus if you can turn the Caps Locक into a Fonts / Scripts कey that can allow up to 7 diacritics variations using this toggle approach: Fonts / Scripts कey press + letter कey tap once = diacritic letter 1st variation (sign/case) Fonts / Scripts कey press + letter कey tap twice = diacritic letter 2nd variation (sign/case) Fonts / Scripts कey press + letter कey tap thrice = diacritic letter 3rd variation (sign/case) Fonts / Scripts कey press + letter कey tap four times = diacritic letter 4th variation (sign/case) Fonts / Scripts कey press + letter कey tap five times = diacritic letter 5th variation (sign/case) Fonts / Scripts कey press + letter कey tap six times = diacritic letter 6th variation (sign/case) Fonts / Scripts कey press + letter कey tap seven times = diacritic letter 7th variation (sign/case) The above does not require the case कey (arrow upwards) to be used because the above has both lower and upper letters. If you feel that 'case कey' producing upper case letters should be used just as it is with non-diacritic letters, then fine. Thus this would mean: - 50 percent variations of the above toggle with Fonts / Scripts कey press + letter कey tap for lower case letters, and - other 50 percent variation of the above toggle Fonts / Scripts कey press + letter कey tap + caps कey for upper case letters. "if you assign Mode_switch and ISO_Level3_Shift to different keys, you can assign up to six characters to one key!" see http://tr.opensuse.org/SDB:Using_the_Extra_Keys_on_the_Keyboard Does this mean it is possible? Could 7 characters to one कey be possible? Features to consider for the Fonts / Scripts कey development: 1. Toggle other कeyboard mapped layouts for example, languages and diacritics. 2. Access other fonts through toggling (Fonts / Scripts कey + another कey) without needing going every time to the particular application's micro layer. 3. Design more styles per letter and/or partner with other fonts and thus more styles on a font and accessing them through toggling (Fonts / Scripts कey + another कey) without needing to go to application's micro layer. It would be nice to have some person/s on board and get these things done. Best, Meeकu

Internet issue, exchange server - Ipswich
by Dalibor Zeman 22 Sep '10

22 Sep '10

Hi guys, I hope you will be able to help me, at least to explain what's going on. A few months ago I lost land line connection (currently in investigation whether it's internal/external problem with Orange as my provider - cannot make/receive calls). Probably in the same time my internet speed for download dropped from 6 MBits to 1MBits I have now. When I check other providers, all of them show the same speed for my location during testing procedure. Do you have any knowledge, info what's happening? Does anybody from my location have the same experience? I haven't used Google to search for this problem yet :-) My post code - IP4 2JL. Thanks in advance for your input. Dali.

Duplicity vs rdiff-backup
by Jon Dye 21 Sep '10

21 Sep '10

Hi all, I've used rdiff-backup in the past for backing up my home directories to a friend's server over ADSL. This works pretty well because rdiff-backup only ever sends the changes. I can delete all but the last 30 (or whatever) days of backups and it still always only sends increments. I've recently started trying to use duplicity as I wanted my backups to be encrypted so that users on the remote server can't see my data. I thought duplicity "builds on rdiff-backup and adds encryption" but I don't think it works the same. As far as I can see, if I want to delete backups older than say 30 days in duplicity I need to have a full backup newer than 30 days. This means at least once every 30 days I need to transmit all the data to the remote end. This takes me over 24 hours on ADSL. Does anyone know if I've got this wrong? Any other suggestions for backups that are *always* bandwidth efficient after the first full and are encrypted? JD P.S. I'm also going to ask on the duplicity list but I thought someone here might know.
