Thunderbird question
by Chris Green 25 May '05

25 May '05

I'm playing with Thunderbird as an 'alternative' GUI mail clinet to mutt. I have it configured OK and reading a remote IMAP server. The one thing I want to do that I can't see how to do at the moment is copy a folder (or even better a folder hierachy) of messages from the IMAP server to a local folder. Dragging and dropping the Inbox copied it and the mail messages in it but dragging and dropping other folders seems only to copy the folder but not its contents. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

GUI mail client for Linux/Unix mbox delivery (i.e. not POP3)
by Chris Green 24 May '05

24 May '05

Are there any GUI mail clients that read Linux/Unix mailbox file mail delivery? I use mutt for most of my mail reading but now that I can do all my mail reading on my home machine it would occasionally be useful to read my mail with a GUI mail reader (e.g. for the very occasional HTML mail that says something useful with the HTML, and/or to look at attached pictures). All the GUI clients I have tried in days gone by have assumed mail comes from a POP3 server and/or munge the local mail spool with specialised indexes etc. that break it for other (better behaved) clients. It doesn't even have to be a Linux program as my Win2k machine has access to the mail on the Linux box. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

Fetching with fetchmail versus sending with SMTP
by Chris Green 24 May '05

24 May '05

I currently read (nearly) all my mail on a remote system (this one) where I have a Linux shell login. I log in to the system using ssh and read my mail using mutt, this gives me access to my mail from anywhere with little hassle. Since we now have broadband at home I can transfer this process (remote ssh login and use mutt) to my home Linux machine. This gives me a couple of extra advantages - virtually unlimited storage space and the ability to use a GUI/HTML mail reader when I'm at home if I want to. The question is should I simply move all my fetchmail bits and pieces from the system where I currently read my mail to my home system or should I receive the mail using SMTP? I already run a Postfix SMTP server on the home system for people to send mail to the outside world, I see no need to authenticate local users, if they can get into my house I may as well allow them to send mail! Would it actually be easier/safer to collect all the mail using fetchmail (much of it is collected on the hosting service by using fetchmail to get it from other places) or does SMTP actually confer any advantages? It would actually be pretty easy just to transfer my .fetchmailrc file from where it is now to my home Linux box and not bother with SMTP at all. If I open up the SMTP port to the outside world what issues are there? I want to deliver mail from my hosting service which handles all mail for my isbd.co.uk and isbd.net domains, I have a web configurator which will let me forward all this mail to my home machine (which is a subdomain of isbd.net) I can thus limit connections to just the hosting service so that will probably deal with most of the security issues, I will also obviously check that relaying is not allowed (I'm pretty sure it isn't now). I will still need to run fetchmail to get mail from a few old POP3 hosts where I get the odd message still. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

How can a user unmount something mounted with smbmount?
by Chris Green 23 May '05

23 May '05

I am using 'smbmount' to mount a Windows file system on a directory in $HOME on my Linux box. This works for a user if smbmount is SUID. However I don't seem to be able to umount the file system except as root, it just says:- umount: /home/chris/win is not in the fstab (and you are not root) The umount executable is alread SUID but this doesn't seem to help. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

Further to ssh security without a passphrase for the key
by Chris Green 23 May '05

23 May '05

I was reading the ssh (and other ssh utilities) manual pages just now and it would appear that hostbased authentication offers an improvement on 'no passphrase' user keys. As I understand it what it does effectively is make a key for the host you are connecting from rather than the user. This key can then be protected from casual access by being owned by root (or even better a special user) and a utulity program ssh-keysign which is suid is used to access the key. If your host machine is reasonably secure and you have root access (or a friendly sysadmin) this does offer a step up in security, though maybe not quite as good as using ssh-keygen - it depends on the way you use ssh. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

/etc/shadow - password field
by Chris Green 23 May '05

23 May '05

I was looking in my /etc/shadow file to see which users had passwords (so I could change them to something more secure, I know some are rubbish at the moment) and now I'm not sure what the password field is signifying. Most of the non-login 'system' accounts like 'bin' have a password field of '*', but there are a couple ('postgres' and another) which have a password field of '!'. Do both '!' and '*' indicate no password? -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."
