FTP/Telnet User Adminitration

Hi, apparently both my FTP & Telnet services are running
<<STATE STIME FMRI
online 2:03:46 svc:/network/ftp:default
root@new-host # svcs telnet
STATE STIME FMRI
online 2:03:46 svc:/network/telnet:default
>>
Could somone please let me know how to give users rights to ftp/telnet to the machine? When I try to ftp to the machine I get an error that the password is incorrect. I am trying to log on as root first, to make sure that it works, and then I will start trying to log on withactual user names. Thank You Alex Tl

root is not allowed to log in by ftp. You need to add non-root users.
It is controlled by:
bash-3.00# cat /etc/ftpd/ftpusers
# ident "@(#)ftpusers 1.5 04/02/20 SMI"
# List of users denied access to the FTP server, see ftpusers(4).

FTP/telnet issue on OL 5 64bit

I am trying to enable FTP/Telnet on Oracle Linux server (64bit), i am still getting same error.
I installed required RPM's
[root@apps xinetd.d]# rpm -qa|grep telnet
telnet-0.17-38.el5
[root@apps xinetd.d]# rpm -qa|grep ftp
lftp-3.5.1-2.fc6

[root@apps xinetd.d]# chkconfig telnet on
error reading information on service telnet: No such file or directory
[root@apps xinetd.d]#

FTP and Telnet are really obsolete and considered a security risk. Both were replaced by the SSH2 package many years ago. Btw, you should use YUM and not install some very old Fedora software using RPM under Enterprise Linux, which can break your system beyond repair.
If you really need a FTP server, simply do the following without the need to install any additional software.
cd /etc/xinetd.d/
vi gssftp
Change the following:
disable = yes to disable = no.
remove the –a option in the server_args line.
/etc/init.d/xinetd restart
You should now be able to FTP to your server.What was the outcome of your previous post here?

FTP & TELNET in Enterprise Linux

hi,
can anyone help me am new in linux world,how can i connect ( ftp & telnet) from
my xp machine to Enterprise Linux, i got connection refused
thanks

First, you'd have to see if any ftp and telnet-server packages are installed:
# rpm -qa | grep ftp
and
# rpm -qa | grep telnetIf telnet server is not installed, you'd have to install it, for example:
# up2date --install telnet-serverIf there's no ftp server package installed, this will work:
# up2date --install vsftpd Then you'll want to start the vsftpd service:
# /sbin/service vsftpd startSergio

FTP Host & user names?

I just bought Fetch because I need to download some photos via FTP from a remote server. The software needs to know my hostname and user name. I use Mobile Me. What should I enter as the hostname? Is the user name just my name or is it also in the form of a web address? I'm stuck! Thanks for any help.

Firstly, you did not need to buy Fetch - if you had looked around on the internet you would have seen that you could get Cyberduck or Transmit and download them both for free - I would say that these are probably better than Fetch anyway. Don't pay for them unless you need to.
Also, what remote server are you talking about? MobileMe is not a remote server and if you have MobileMe all you need to do is log into your account and go to your iDisk and you can retrieve any photos that you need from there by opening the file on your iDisk directly, you don't need Fetch to do this.
If you are really talking about a remote server then the details you need to enter in Fetch are those server details to connect with it - which hosting company is it with? You need to contact the hosting company to get those details or talk to the person who owns the remote server and get those details from them.
For MobileMe - your own account you don't need Fetch anyway, so you might just have wasted your money!

"orcladmin" access has been disabled & some FTP problems & user IDs

Hi,
I was working on a problem with OCS 10g (10.1.2) where we can only upload/ftp successfully file types (with extensions: BMP, JPG, WAV, MP3 & LOG). Txt, Doc and XLS files get an access denied error.
So I try to logon to "http://myocsserver.com:7778/content/" as orcladmin to change any applicable settings to allow all file types to be uploaded to my library in Content Services. When orcladmin access gets an error message "Error
Your access has been disabled. Contact your system administrator for more information."
I've tried looking at the product documentations, OTN and even MetaLink. Unfortunately I couldn't find anything. Can anyone tell me how to get my orcladmin account to work again on "http://myocsserver.com:7778/content/" ?
When i goto "http://myocsserver.com:7777/oiddas/" and even "http://myocsserver.com:1810", orcladmin works just fine. When I examince orcladmin account in OID I see that it is not locked and is enabled. So I can't seem to understand/figure out why I get the error "Your access has been disabled. Contact your system administrator for more information."
BTW, we also tried to create another super user account. We created it in OID granted it with all the privileges available and assigned it a domain admin role. However when it is able to logon to "http://myocsserver.com:7778/content/" it is not able to access the administration mode.
Hopefully someone can point me in the right direction.
Thanks in advance.
Regards,
-Ken

Hi user544366,
Thank you for the suggestion, I appreciate it.
Hi all,
Got a fix from Metalink support personnel on the orcladmin user access disabled issue. Apparrently you have to de-provision Content for orcladmin and re-provision again. After doing that we were able to login to Content services again ("Http://ourOCSserver:7778/content/").
My remaining issue now is that even after I log on as orcladmin to Content Services I cannot find any settings that will fix my original problems. Using any user id (orcladmin etc) I can only successfully upload files w/ extensions (WAV, MP3, BMP, JPG & LOG) to Content services. I cannot upload -fails - (DOC, TXT, PDF, PPT & PDF) files to Content services. If I use FTP I get "Access Denied" error. If I use the web interface to upload I get an error "Error An Item must be selected etc."
TIA.
:)

FTP & Telnet using Tool

I know that there have been some discussions running from time to time
talking about integrating FTP and Telnet with Forte. Has anyone implemented
either of these in Tool or has the trend been towards wrappering third party
products? Some feedback would be terrific as we have the need to use both
protocols and I would like to avoid some pitfalls up front.
TIA

IIS Server / Ftp Isolation user not working in Windows 2008 R2

HI,
Please help as last time when we are still using the Server 2003 we don't have issue with the IIS virtual directory, what I mean is when the user log in there username and password they can only see directly their folder but when we already shift to server
2008 everytime we log in we can able to see other users folder , of course even I try to open other users folder they cant able to access only what belongs to me. I hope we can still do like last time, we can only see our own folder in file explorer.
Please help..
Thanks,

Hi,
As the permissions on IIS virtual directory are not similar with the permissions on windows file systems, I suggest you ask for help from IIS7 forum for better and accurate answer to the question.

How to set SMB and FTP sharing for different users?

In Tiger FTP and SMB sharing was different options with their own settings each other. In Leopard there if i enable user for sharing, it enables for all protocols together.
Another problem. In file sharing i can add shared folder, but what's sens of it, if the whole filesystem is shared (at least FTP and AFP, not SMB, thanks god) and there's no way to remove this share. Just shortcut? How can i create ftp sharing, allowing user to see only his folder, not the whole filesystem?
Any advices are pleased, except to get Leopard Server Thank you.

OS X Client FTP implementation is not comprehensive at all. Apple does not make FTP serving a priority for OS X (on the general principle that it is not really necessary for most consumers). Thus, by default you can't enable/disable FTP for individual users. Nor can you create FTP only users.
However, a useful product called [Pure-FTPd|http://www.pureftpd.org/project/pure-ftpd], provides the missing functionality for free to all UNIX based systems. Even better, [PureFTPd Manager|http://jeanmatthieu.free.fr/pureftpd> provides a GUI on OS X for managing it.
This product is probably overkill for a single-user situation - but it is a great example of leveraging the UNIX platform of OS X to significantly enhance file sharing capabilities to server level.
Cheers,
Rodney

Question: FTP jobs local user field

Just wanted to get an idea if anyone knows if as a best practice this should be populated or not. We don't have the configuration setting 'FTP Local User Mandatory' checked, but I wonder if it should. I am assuming that if local user is not populated that the agent service account then is what the job runs as.

Everyones security requirements may vary.
I would suggest making it mandatory as a best practice as it forces you to be consistent. Then when that one-off happens and you need to deliver to a "secure" location the RTU id is obvious and not hidden by falling out to the agent service and a different RTU could be used that is permissioned. (we name our RTU and logon accounts for services differently)
We have very few FTP jobs left in Tidal (we have to host our own FTP Solution anyway so we just use its API to send / rec) which will all be retired when we move to 6.X

Mark,
Unfortunately, Forte doesn't offer any ready-to-use internet

Forte.
Does any one know if SUN plans to include this into Forte?

Hi,
Unfortunatly, Forte does not provide SMTP and POP3 protocoles.
But, you can use External connections to do it if you need.
You can find a simple SMTP send mail sample code on
http://perso.club-internet.fr/dnguyen/ . The receive should be as easy as the send.
For MIME base 64 encoding and decoding, it should last one or two weeks of coding
(if you need optimization).
One advantage of coding this in Tool directly is the portability.
In your case, on NT, you could also interface with MAPI using for instance the
ActiveX interface.
By that way, you will already have SMTP, POP3 and MIME.
Hope this helps,

You would have to pick a library to do that. There are several commercial libraries. Out of the open source ones, the most mature one seems to be Ganymed SSH-2.

Slow Authentication on FTP

I have an OS-10.5.1 Server that I am presently using for nothing other than an FTP server. (users are set up with OD passwords in LDAPv3 local.) Updates have been held back to 10.5.1
Authentication is very slow, about 15-20 seconds.
I've done some research on this and tend to think it is attempting RFC 931 authentication. I would like to turn this off but only find ways to turn this off for xinetd or xftpd. These were on earlier servers but the Leopard server uses ftpd.
I don't see /etc/ftpd.conf file so I'm wondering where and how I should change this setting. If someone thinks my problem is elsewhere, I would welcome those comments too.
Any help would be greatly appreciated.

O.K., is this an initial login slowness issue only or is it slow for every action?
If it is only for login then this sounds like it is more a DNS issue than a confgiratoin issue.
Check to see if you can resolve the clients address from the Server with something like _nslookup ipaddress_.
