<0> ssh and ftp is different of connection rite
<1> yes
<1> ftp is for transfering files, ssh is encrypted terminal like telnet
<0> how about openssL
<0> ^_^"
<1> thats the enryption
<1> used by ssh and webservers etc
<1> or encrytion layer or whatever, its not a service
<0> ssh and openssL is same category encryption terminal
<1> openssl is part of ssh
<1> ssh is the terminal program that uses openssl for encryption
<0> i c ... so how can i install openssL for my ssh terminal
<0> i type netstat and it show tcp 0:::::ssh .. is that meansi am using ssh connection but not ftp ?
<1> yes if you have ssh installed then openssl is probably already installed
<1> you can type "service sshd status"
<1> should say ssh is running, ftp is another service, you can transfer files with ssh also using scp, but the other system has to have ssh installed on it
<0> it comes sshd (xxx xxxxxx) is running .....
<1> that means ssh is installed and running...but no not ftp
<0> so is this ssh running with openssL ?
<1> yes
<0> can i know what is the version openssl current this ssh is running ?
<1> uumm
<0> can i have ssh and vftpd together?
<1> type openssl version
<1> or openssl --version
<1> vsftpd yes
<1> service vsftpd start
<0> so it won't conflict with existing vsftpd?
<0> is this vsftpd will come together with openSSL encryption too ?
<1> u only have one vsftpd installed and ssh wont conflict
<1> ummm
<2> ssh and ftpd are two COMPLETELY different protocols. why should they conflict?!?
<1> yea it works with the ssl to provide you with encrypted ftp if you configure it
<2> and, no, FTP doesn't use ssl normally, ftp over ssl is a rather nonstandard protocol, I suggest you use sftp/scp (part of ssh) instead.
<1> vsftp can use ssl
<1> it does sftp
<0> .......
<0> so the vsftpd already (sftp/scp)
<2> sftp is part of the SSH suite, not ftp over ssl. sftp is more closely related to scp
<0> so is the vsftpd already (sftp/scp) ?
<2> and, sftp/scp are part of SSH not FTP
<2> are you dense?
<1> vsftp can use ssl
<2> it can. but ftp over ssl is _NOT_ sftp.
<1> You can quite easily configure your vsftpd server to use OpenSSL encryption, so that usernames & p***word, and even data files, are encrypted during transfer.
<2> and, ftp over ssl is a rather nonstandard protocol. when you HAVE scp/sftp, why do you want to mess with sftp over ssl ?
<1> oh ok
<0> ........ so what should i install ?
<3> ARGHHHHHHH
<0> ..... i_i "
<0> so how can i know my current ssh is under sftp/scp ?
<3> shinyo22, try rephrasing... the queston is gibberish
<2> from another system, `scp username@hostname:path/filename localfile` will copy a file from the remote system. or, `scp localfile user@host:path` will copy it to the remote system.
<2> man scp
<4> thanks
<5> secure ftp server?
<4> flooded the shinyo guy off too huh
<0> ......i_i
<4> or not
<6> anyone here use Scalix?
<0> just not sure nowaday which one is better ? remain ssh protocol or vsftpd
<4> apparently sftp is part of ssh, my bad
<0> ic
<4> with sftp you can issue ftp like commands to ssh to transfer files
<3> shinyo22, if all you want to do is move files to and from unix systems in a secure way use ssh ( scp/sftp )
<4> i use scp
<2> the only place I'd use ftp would be for anonymous readonly access, and even then, I lean towards preferring http
<0> is it my existing ssh ?
<5> shinyo,just open the sshd config file,in the end of the config,you will find something like "Subsystem sftp /usr/libexec/openssh/sftp-server"
<4> yes
<2> shinyo22; yes, it should be enabled by default in centos.
<0> where is th sshd config file?
<3> shinyo22, /etc/ssh/sshd_config
<2> its already configured quite reasonably by default, centos has sftp/scp enabled
<0> the "Subsystem sftp is not" is not in the config file .... how to check the sftp/scp status?
<0> service sftp status ?
<4> how bout just "sftp me@mybox"
<0> huh type it ?
<2> sftp isn't a 'service', its part of sshd
<4> i would think you should be able tyo sftp to yourself to test it
<4> me=your useraccount mybox=yourhostname
<2> Iconx; this guy is slow, you better tell him -exactly- what to type. how to spell his username, how to figure out what his local address is.
<0> i_i "
<4> haha
<4> no kidding
<4> i think thats supposed to be a face of somekind?
<4> i_i"
<4> hmm
<0> crying face i_i "
<4> that was my first guess
<4> im sure your sftp works
<0> i type sftp <username>@<hostname/publicaddress> correct?
<0> BTW is it i use back the centos to sftp back to myself ?
<4> yea
<0> Iconx: it seem just connecting and now show msg couldn't read packet
<0> oh .. i think would it becox of the port ?
<4> no dont think so
<0> because we have a firewall
<4> nope should be able to connect to yourself still
<4> try just ssh me@mybox
<5> or just ssh username@127.0.0.1
<4> stitches taste gross
<0> oh if i not using public address, i can connect it
<4> yay
<0> if i use the local address no problem
<0> but i used public address ...connection seem got problem
<0> i remember the firewall actual forwarding the different port instead of port 22
<2> you typically can't use your external address from behind your NAT firewall, NAT systems aren't real happy about packets from inside being rewritten to go back in, thats a double translation, and it rarely works
<2> users outside should be able to use your public IP if you've forwarded port 22/tcp (ssh) to the server inside.
<7> well actually if you add an SNAT rule you'll be able to get to your external and it will do what you expect
<2> misc--; yeah, but that extra set of rules usually isn't part of most firewall stacks, especially dedicated routers and such.
<7> yes that is true
<7> it depends on the router
<2> and its no big deal. if you're on the local net, use the local addresses.
<4> know if a netscreen can do that?
<7> it is if you have severs behind the firewall that DNS lookup to your public IP
<2> use split DNS, and have a private zone for your local net. or even just use /etc/hosts
<7> you could, but it's a pain if you don't need it, most of the time you don't
<7> and you can't tell your DNS server to use /etc/hosts and push it out to the clients. Maybe you can but not with what I've used, dnscache and others
<4> opinions? : whats a good newsletter mailer? im using mailman
<2> thats what I use for email announcement lists, etc.
<0> sorry .... a dummy question, my outside user what kind of client ther can use for connect to this sftp ?
<3> sftp?
<0> er ... ya ... sftp
<2> there's a freeware windows GUI app, winscp, thats pretty good
<2> otherwise, most any unix or linux system has sftp/scp command line.
<2> as does mac osx
<0> actually do u all expertise mind i ask
<0> what kind of connection good to use for file transfering from outside and inside our office
<2> what do you mean, 'kind of connection' ? physical internet connection? faster the better up to a point.
<2> if you mean protocol, scp/sftp
<0> protocol .... scp and sftp is the same protocol rite
<2> shinyo22; yes, pretty much (to be precise, both use an SSH connection, but they invoke different remote commands within the ssh session... equivalent for most purposes)
<0> so i recomend my customer use scp or sftp ?
<2> depends entirely on yours and there needs and requirements.
<0> i used the filezilla connect it seem is sftp over SSH type
<0> and can i add public/private key in these sftp?
<2> yeah, same keys as ssh uses.
<0> can i know what is the command for me to add the key to it?
<2> google for ssh-keygen
<2> that generates the keys, you need to copy and add them to the remote system manually
<0> is that lot procedures ?
<2> you know, THIS IS ALL IN THE MANUALS FOR CENTOS... http://www.centos.org/docs/4/html/rhel-sag-en-4/s1-openssh-client-config.html
<0> oh thanks for this info
<0> i will try to look into first
<0> thanks you very much for all the information thank thanks
