debian aptitude(1) "un-update"
Hello, I've marked too many packages to update (with the "U" key of aptitude) and would like to undo this. But I can't find a way except for holding them all. Is there a way to make aptitude forget a package marked for update and get it backed to a simple "installed" state?

As far as I looked at it there are conflicts between perl-base and libperl5.8/perl. At first I suspected that there are missing upgrades of other packages but this upgrade is already 9 days old. As it is now - if I'll go on with the upgrade it'll remove half the packages on my system because they have unmet dependencies. I use Hamakor's mirror, in case this makes a difference.

RE: is Overnet safe?
essentially it opens a port to a 3rd party client, lets call it a supernode and converse with other clients from there. i.e. no need to open a port. now, there's a hitch. by not opening a port then it is more difficult to converse with you and thus the connections will be slower and maybe other clients will decide not to converse with you at all because of that. you must understand that in order to "open a port" on your machine, the other party will send a message to the supernode, you will then receive the message because you are already connected to it. Then, your client will connect to the other client (the other client mustn't be behind a firewall). If the other client is also behind the firewall then its upto the supernode or a delegated party to decide if to reroute your communications between you at a considerable cost for himself of course, and thus will probably not. Of course it all depends on the network and protocol you use.

I can't find overnet's protocol spec right now, but I've seen that other popular protocols use "public directory servers" which can be accessed to search files and sometimes download them (if the host on the other side is on a "real" IP). i.e. it could be that many of the files you found aren't really accesible to you because of your situation. It's a bit like the dead-tree telephone directories which used to be in public telephone booths before the 80's - the directory itself is public, but you still need a token to be allowed to make a call. As for safety - it's like any other network-based program - if the program can accept packets from outside and there is a bug in it about processing the data then the risk is larger than the absolute zero. The main difference weather you open a port or not is that without opening a port it should be more difficult to "inject" packets to your program from just any computer on the net, but instead only computers with which you established connection pose a real risk (but we are not talking in absolute terms, at least theoretically any computer can send "the right packet" if it knows what to send. See the recently found TCP security risk widely publicised in the press). Hope this answers your question. If you'll find the protocol spec then maybe I'll be able to give you more specifics about it (if I'll have time). --Amos = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

I don't remember the exact specifics, but at least some of these protocols have a system where if the uploading user is behind a firewall and the downloading one isn't (or the port is open or whatever) the message can be sent to the file owner through a third party to perform the connection instead of the downloader which allows bypassing firewalls. > 2 - does running Overnet pose a danger (with or without opening a firewall > port)? > > -- > Shlomo Solomon > http://come.to/shlomo.solomon > Sent by KMail 1.6.1 (KDE 3.2) on LINUX Mandrake 10.0 > > > = > To unsubscribe, send mail to [EMAIL PROTECTED] with > the word "unsubscribe" in the message body, e.g., run the command > echo unsubscribe | mail [EMAIL PROTECTED] > > > +++ > This Mail Was Scanned By Mail-seCure System > at the Tel-Aviv University CC. > = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

I know that you can make it Forget that some packages are appropriate for the new section.

You only need an open port for incoming connections(i.e. sharing files). So you can still run it with some limited functionality It means that you are getting a so-called low-id. Thus you can only connect to non-firewalled clients. Of course, the downloads would not be as kickass, as you are limiting your sources list to something like 25% of the whole network. Ok, I see that I starting to just rephrase the original FAQ, so why don't you read it yourself? :)) http://www.overnet.com/documentation/faq.html http://www.overnet.com/documentation/lowid.html SS> 2 - does running Overnet pose a danger (with or without opening a firewall SS> port)? Well, look at it this way...overnet was still closed source, last time I checked(which is just now). Am not about to doubt the skill of the developers, but...my pet paranoia tells me that every server or client you are running poses a threat to security. It really does not matter if it has an open port or not as long as it is getting a data stream originating holy Random knows where. So locking it down into a chroot jail seems like a good idea, reducing the risk if done properly. In fact I admit that I done that when I was running overnet. It is statically compiled so locking it down is a matter of reading `man chroot`. -- Sincerely Yours, Vasiliev Michael = To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
