hi i'm using openssh , and i want to know how i can login to a remote computer from mine ( which has a dialup connection -- dynamic ip, but with a dyndns.org hostname) without being asked for a password. i used ssh-keygen to generate both dsa & rsa keys and i put the pub keys in the remote computer's ~/.ssh/authorized_keys2 & ~/.ssh/authorized_keys, but it still is asking for a password. What have i done wrong ? regard omicron -- ****** An optimist sees light at the end of every tunnel.

What have i done wrong ? There are several questions here: 1. What password is it asking of you? The RSA and DSA private keys usually have a passphrase associated with them, which the SSH client will ask of you. 2. Have you configured client and server for RSA and/or DSA authentication? 3. Are the SSH client user's public keys in ~/.ssh/authorized_keys[2] in the correct format? Are the permissions on the files correct? Are the filenames correct? IMHO, the best way to discover what the real problem is, is to call sshd with the -d option on the SSH server and use 'ssh -v -v' on the client, monitoring the result. That way, you can trace just about everything that happens on the client as well as the server. This should help you find the cause of your problem. HTH Tobias

Missing anouncements?

by Frank Steiner

Hi, just checked the "Patches, Updates, Bugfixes" webpage of suse.de for SuSE 6.4 and was quite surprised to find 23 updates marked as security updates for January and February, while the security-announce mailing list contains only 4 announcements for Jan/Feb, although some of the updates are already quite old like cron or gnuserv. Is there some special reason for that big discrepancy? Best regards, Frank -- Dipl.-Inform. Frank Steiner mailto:fst@informatik.uni-kiel.de Lehrstuhl f.

ssh and saint... and popper

by Gediminas Grigas

Hello, Saint says: "ssh versions 1.2.27 and earlier if compiled with the --with-rsaref option are vulnerable." ... "This problem can be fixed by upgrading to ssh-1.2.28. If this is not possible, then install the ssh patch " Suse has latest patch which produces ssh-1.2.27-209 for SuSE 6.3/6.4 (this version was uploaded 15/Feb or so.) So i thought it looks like brand new vulnerability... The only link given to 1.2.28 sources is on ftp://ftp.cs.hut.fi/pub/ssh/ which seems does not allow anonymous users... I would prefer rpm, becouse i have one machine without any sources due low HDD space, so it couldnt compile at all - but rpmfind did not find any 1.2.28. Oh well i would compile sources on other suse 6.3 machine, only if i could get them. So my question would be: is it new ssh bug, and no vendors yet developed patch, or theres some mess with versions and saint? Where i could get sources of ssh-1.2.28? P.S. The saint i downloaded today - so it should be up to date P.P.S. Saint also finds complains on popper, even althought i patched it on last suse rpm update (pop-99.11.2-5) it seems provaides qpop 2.53, so i got sources from eudora.com and upgraded popper to 3.1.2 (what a version jump?!) QUALCOMM`s note on this: Security Vulnerability Some versions of Qpopper are vulnerable to buffer overruns. Qpopper 2.41 and older can be used to obtain root access to your system. Qpopper 2.53 and older may permit an attacker who has access to a valid account to obtain a shell with group-id 'mail', potentially allowing read/write access to all mail. All users of Qpopper are urged to upgrade to the current version. :( Sincerely Yours, Gediminas Grigas mailto:gedas@kryptis.lt

Does anyone know, what someone was trying to do? Any help is apreciated! Thanks, Ralf Ronneburger

about teh cookies problems someone was mentioning///

by jfweber＠eternal.net

******* Where does a newborn go from here? The Net is Vast, and Infinate...******** whelp guys, Here's how I solved the cookies problems evne on windwoes! make the cookie file "read only" It works pretty well, even for MSN sites. apparenlty thier computer tries to write to your hard drive and thinks , since it sent the message that it must have worked, or if they get an error message they dont keep trying, either way is ok by moi! It only annoys my users a little bit, I have them surf to evey "personalised" site they have and setup personalisations, before I make the file read only.. and then tell they they dont have any more alloted space to do more, unless they want to delete some??? <evil grin> and on a really other topic: since I cant even get an email reply out of Suse US; phone tree never has a human pick up I went ot Best Buy , which so many of you have touted, and got suse7.1 pro for $49 !!! I am about to log out of this y'ar windwos and get into serious installation mode ... Blondely, j afterthought--- Clinton has replaced the military salute with a wink.
