iptables question
by Mark Rogers 01 May '13

01 May '13

I have an Internet facing server running pptpd. Users who connect via pptp need to be able to route through the server to the rest of the Internet. As well as configuring net.ipv4.ip_forward=1 I also have iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE .. and it all works. However, is the above iptables command too broad for an internet server? Doesn't it effectively mean that anyone can send traffic through it? Assuming the pptp interface is ppp0 I would have expected (having very little iptables knowledge) that: iptables -t nat -A POSTROUTING -o eth0 -i ppp0 -j MASQUERADE .. would be better but I'm just guessing and I don't want to kill access to the remote server by playing! Given that every howto I find says to use just "iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE" I assume that's actually right, so I think I'm just asking for help understanding why.

Widespread spamattack
by Anthony Anson 30 Apr '13

30 Apr '13

In case anyone doesn't know, there's a widespread infiltration of btinternet and yahoo accounts, spreading multiple spam messages. Beware of trying to open any unknown URLs contained in emails from those sources. (My firewall warned me of just such an attack, seemingly from an old friend. Whether it could have infected a Linux box I don't know.) -- Tony http://www.girolle.co.uk/

Converting photogravure (back) to photograph quality?
by Anthony Anson 30 Apr '13

30 Apr '13

Does anyone know of a program which will take a (dotty) photogravure pic and convert it back (as far as is possible) to the original one from which the plates were made? -- Tony http://www.girolle.co.uk/

System temperature monitor?
by Ted.Harding＠wlandres.net 29 Apr '13

29 Apr '13

Hi Folks, My laptop (which was quite busy at the time) suddenly switched itselfr off. I checked the power lead etc., and then switched it back on, and since then it's been fine. I don't really know what happened. It may have been a loose connection in the power supply (the battery is shot, so any interruption kills it immediately); I may have accidentally tapped on the power button (I was typing furiously at the time); but more probably I suspect that the machine may have been over-heating and decided to switch itself off. It felt quite warm, but not really hot. This led me to look for any program that monitors things like the state (including temperature) of the system (e.g. CPU temperature or whatever), but I didn't find anything. Any suggestions as to what I should look for? This is a rather old Debian system (2010) on which I'm running "classic Gnome" (thank God), and for various to reasons it has reached the state where Debian-sourced updates or further software can no longer be installed off repositories. So anything new would have to be installed from scratch. An alternative might be the contents of something under /dev which stores ambient system information, which I could then decipher for myself. But I'm also wondering where that might be! With thanks for any suggestions, Ted. ------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)wlandres.net> Date: 27-Apr-2013 Time: 21:56:01 This message was sent by XFMail -------------------------------------------------

Looking for simple web photo gallery software with some very specific requirements
by Chris Green 29 Apr '13

29 Apr '13

I'm after a web application to display pictures, there are zillions of them out there but it's difficult to find one to match my requirements:- Take an existing directory hierarchy of pictures and use it to organise the album/gallery. Don't copy the pictures, use them direct from the existing directory structure. Must not require any write access to the pictures directory. The thumbnails and other information must be stored elsewhere. No need for any picture manipulation at all, just a way to navigate through the hierarchy and view the pictures. Preferably no database and the ability to use EXIF information but these are not absolute requirements. It can use PHP, Python, Perl or anything really, slight preference for Python or PHP as I can modify/maintain it more easily myself then. -- Chris Green

Accessing IMAP from W*****s
by Ted.Harding＠wlandres.net 26 Apr '13

26 Apr '13

Greetings All! My apologies for even hinting at any abominations, but I would like to know the answer to this problem -- and of all people I think ALUG may be able to help! Situation: I have a remote IMAP account with 1and1.co.uk, which my mailer accesses basically via telnet on port 143 (along with email address thereon as userid and a password, both of which I know, of course). The problem: Suppose I am visiting a friend or family, but without my computer (which has the access built in). They all use W*****s systems. I would like to be able to see my emails on the remote IMAP server, perhaps read some, and delete any I'm not interested in. Maybe even reply (but this is not my priority). So: Is there a procedure with some W*****s softwrare which they would have installed by which I can have such access? Ideally, I'd be delighted if this could be done with a browser (e.g. Ex*****r) so that there's minimal interference with the machine I'm using. And (and here I return to the fold) if that were possible then I could also do it using Linux (which would add to the coterie of friends from whose places I could do this). But my attempts from my home Linux system got nowhere (short of setting up an IMAP account in the mail agent , which of course is already there). The host address for access to IMAP accounts is imap.1and1.co.uk port 143 Much gratitude for any useful advice! Best wishes to all, Ted. ------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)wlandres.net> Date: 23-Apr-2013 Time: 18:02:39 This message was sent by XFMail -------------------------------------------------

Accessing IMAP from W*****s
by Ewan Slater 24 Apr '13

<quote> If you have a spare USB stick, you could install Portable Apps http://portableapps.com/ on it and use something like Thunderbird http://portableapps.com/apps/internet/thunderbird_portable to access the IMAP account. I've only used it with PC's with XP installed but believe it works with most varieties of W*****s. All you do is stick it in a USB socket and the apps automatically fire up. When you remove the USB stick, it doesn't leave anything behind on the host PC. </quote> Portable Apps works on Windows 7 and XP. Don't know about Vista or 8. Another option would be to take a Virtual Box Linux VM with you and use that. My €0.02 Ewan

old tat going free
by mick 23 Apr '13

23 Apr '13

Or really useful old hardware..... Another clear out means that I have some old tat to get rid of. Someone may find some of it useful. If so, let me know, otherwise it's going to the wee recycling dump. Two EZ PCMCIA 10/100 ethernet adaptors (cards slot into old adaptor slots and provide RJ45 ethernet connectors) One Dell external CD/DVD drive wich uses the Dell connecting cable (with cable) One Dell external CD/DVD drive which uses USB connecting cable (with cable) One 5 1/4" floppy drive (really). I have also found a box of Digital Research 5 1/4 floppies with GEM etc dating from 1987 if anyone is feeling really nostalgic. One "universal modulator" from Maplin (one of these http://www.maplin.co.uk/programmable-universal-modulator-33050) Mick --------------------------------------------------------------------- blog: baldric.net gpg fingerprint: FC23 3338 F664 5E66 876B 72C0 0A1F E60B 5BAD D312 ---------------------------------------------------------------------
