Server :: Pure-ftp / Openssh Failures - Transfer Files
Apr 22, 2010
I need by searching this site so I haven't had a need to sign up since I can't really help anyone as of yet. With that said here is my problem: I'm running a VPS with CentOS RHEL 5 host-in-a-box, I just did a rebuild of the server and after a day or two pure-ftpd and sshd unexpectedly close out any incoming connections. I am the only one that uses ssh and ftp so I'm not sure what the problem could be. I checked the logs and there is nothing to do with not being able to bind on the address.
I tried connecting through ssh in verbose mode and it connects to the server just fine, but drops the connection before it asks me for my key pass phrase. If I enable password access it will drop before it asks me for it's password. I've tried restarting sshd and ftpd. I've tried rebooting the machine. I've tried google, but this problem seems to need a little more specific trouble shooting. I can get in through console access, but that doesn't help me much when I need to transfer files.

I have configured openssh 5.8p2 with centos 5.6. My sftp is working fine with chroot environment but i am having problem with SCP. I am dealing with muliti Redhat servers. When i try to transfer data from other linux server through scp it gives connection refused. For e.g ssh 5.8 is configured on new server and i want to transfer files from old server which is using openssh 4.3 version.i created same username and password on new server as on old server.My sftp users on new server has no shell access but only sftp access. When i try to scp from old server to new server it gives error connection refused. Is the below configuration only for sftp and can't scp? According to google the configurations i found are for scp and sftp. Do i need to generate ssh keys by giving users on new server shell access, once created then stop shell access again, as i dont want to give shell access permanent for security reasons? but i want to use ssh keys for more security as well.
Port 22
PermitRootLogin no

I am having problems troubleshooting my pure-ftpd setup. I am always getting a 530 authentication error. I attempted to correct the problem by doing the following:
# pure-pw mkdb
# ln -s /etc/pure-ftpd/conf/PureDB /etc/pure-ftpd/auth/PureDB
# gedit /etc/pure-ftpd/conf/PAMAuthentication
[code]....
This create a new error. 421 Unable to read the indexed puredb file (or old format detected) - Try pure-pw mkdb I am getting a feeling this is getting from bad to worse. I attempted to remove pure-ftpd and pureadmin to start over again. However, it appears I cannot remove everything. I attempted the following:
apt-get remove pure-ftpd pureadmin I am not sure what this really does because I can still see the folder /etc/pure-ftpd and I cannot remove it. I could not use rm /etc/pure-ftpd because the system said it was not empty. I also tried sudo aptitude remove pure-ftpd pureadmin . Again I cannot completely remove the folder. How do I completely remove pure-ftpd and pure admin and all databases, files and folders so I have a fresh system ready to start the install again?

I have set up pure-authd and pure-ftpd. They are both running, I have created the socket etc.
In my authentication module (a php script) for testing purposes I have done a vardump in to a file, and have realised that pure-authd is not passing on any variables (username, password of the current person trying to log in via ftp) to the PHP script.
I am sure the authentication module is working (have tested it vigorously on the command line), but after 10 hours wondering why it wouldnt work and messing about with the script, I have realised that the variables were never even getting in to the script in the first place!
I am running the processes such as this:
Everything seems as if it is working other than this. For instance, when testing the setup with a very basic auth module which doesnt require a username or password (the basic module just passes "auth_ok:1" to pure-ftpd and the user is then logged in), I can log in to the FTP server fine.
But like I say, a vardump ($argv) on my proper PHP authentication script would suggest that no username or password are being passed to it.

I have 2 computers on the same network that i need to link together to transfer files 1 is a web server the other is a minecraft server. the problem is that the file transfer will be constant as the minecraft server will constantly updates files on the web server and I dont want it to go to the router then to come back to the web server. I want to add a second network card to each computer and link them together and use this second connection to transfer the files is it possible?

I would like to transfer files from my PC to my account at a sftp server, and I don't know how to do it.
My PC is running with:
User: User1
Address: 10.0.2.3
My sftp account is:
User: SFTPUser1
Address: sftp-server
I can access the sftp server with the command:
Code:
sftp SFTPUser1@sftp-server
The sftp server doesn't answer to ssh requests.
How can I transfer files to the sftp server?

When trying to transfer files from my server to my desktop, the files never get fully transfered. I have windows cmd running a ping to my server, and all is fine until i try to transfer files. Some will transfer fine, and then out of nowhere the server will stop replying. I then have to restart the server to gain access to it. A 2 GB file will transfer about halfway, and then the server will not be able to be pinged. I have static IP on the server and my desktop. Running XP x64 and Ubuntu server 32-bit 9.04. Tried using Samba and NFS Exports. I have both my desktop and server connected to the same gigabit switch, and then my switch connected to my router.

I have a server with Private IP and without any public IP. I want to transfer files to the private IP. I can log in to the Private IP through SSH. So basically I installed vsftpd in the server with Public Ip and tried to ftp the public ip from the private ip but it is not working.

Here's the system:
1 server running regular Ubuntu, 40km above the surface of the earth on a scientific balloon behind an iridium modem (RUDICS) connected to its serial port
1 server on the ground running Ubuntu server
1 intermediate server used for contacting the iridium system from the ground server
I'm not sure if all the above details are completely necessary but I included them for completeness. I would like to be able to log into the balloon server and transfer files in both directions. The procedure for connecting is to telnet to the intermediate server and then to issue some modem commands to call the balloon. The balloon server is set with getty running on the serial port connected to the modem. The way I have figured out to transfer files is to run kermit on the ground server and connect to the balloon server through the intermediate server, then run kermit on the balloon server, and set it as a file server with the server command.
However, there is some sort of timeout or something, and only a few kB of any file gets transferred before the connection is broken. After that it seems like the ground server is trying to get the file from the intermediate server (which has no useful files on it at all). The file transfer screen stays open and it keeps trying and trying to transfer, until I type ^C. I don't know if there is a way of detecting through a kermit command whether the connection is still open or if there is some sort of switch to make the transfer automatically stop once it has stalled.
I have been reading about No Kermit Server (NKS) protocol, which seems to be designed for a system like this where the connection is across a third server. Is this likely to do a better job of keeping the connection open and the file transfer going? How can it be implemented? Is there any kermit command to determine from the ground server whether the connection is actually still open? Is there any way of telling whether the connection goes all the way to the balloon server or whether it ends at the intermediate server? I actually just learned about kermit today.
On a related note, is it possible to have the balloon server running getty on the serial port but still have the port accessible for reading and writing by, say, a python script (which could use the modem to dial down to the ground when it isn't in use)? It doesn't seem to work but I'm wondering if there is a way. Is there a way to temporarily stop getty, then restart it, or is this potentially hazardous? Keep in mind there will be no way to contact it if something goes wrong since it will be 40km above the earth.

I use Ubuntu Lucid and use the terminal to access my virtual server (GoDaddy - Red Hat Fedora Core 6). Using the terminal and entering SSH [account name]@IP gets me there. I can manipulate the server then.
But how do I transfer files to/from the Ubuntu terminal to the Fedora server? I want to (using Evolution) email a file on the server to someone.

I'm carrying out a project for my university (CIT in Cork, Ireland) and I'm using CentOS running over WMware. I have a server and a client. The server has no GUI (command line UI) while the client has a UI. I need to install a Simple Forum Machine application and I'm told to FTP the files into the server. I figured out that the best option is to load the files in the client via the GUI and then ftp them in the server. How do I transfer the files from a the client t o the server using FTP? I'm totally new to Linux so the more details the better. Also I'm trying to mount a USB key on the server but have had no luck.

I need to scrape logfiles and do some pattern matching for a series of hardware and system faults;
For example:
Network interface down / up
IO errors
Out of Inodes
Out of Diskspace
Memory Errors
Power Failure
When the appropriate Strings appear in the log (assuming /var/logs/messages)Then a trap will be sent. (Customer specific SNMP solution) So what I need (I think) is a list of the strings I need to match.Has anybody any idea where I can find a list of strings which will definitely appear in the log - RHEL5 ?

I am currently having problems with my RAID partition. First two disks were having trouble (sde, sdf). Through smartctl I noticed there were some bad blocks, so first I set them to fail, and readded them so that the RAID array will overwrite these. Since that didn't work, I went ahead and replaced the disks. The recovery process was slow and I left things running overnight. This morning I find out that another disk (sdb) has failed. Strangely enough the array has not become inactive.
md3 : active raid6 sdf1[15](S) sde1[16](S) sdak1[10] sdj1[8] sdk1[9] sdb1[17](F) sdan1[13] sdd1[2] sdc1[1] sdg1[5] sdi1[7] sdal1[11] sdam1[12] sdao1[14] sdh1[6]
25395655168 blocks level 6, 64k chunk, algorithm 2 [15/12] [_UU__UUUUUUUUUU]
Does anyone have any recommendations as the steps to take ahead with regards to recovery/fixing the problem? The disk is basically full so I haven't written anything to disk in the interim of this problem.

I am setting up a cluster of servers which use Centos Directory Server for control of logins, etc and kerberos for authentication. The basic setup is working fine, I have been able to manually create accounts using the directory console and these accounts seem to work. Now what I want to do is automate the process of creating new accounts. I am writing a perl script which can be run by one of the server administrators, they supply a small number of arguments and it should create a new user in the directory server, and also create a principal in the kerberos.
I want them to be able to do this using their logged-in kerberos credentials, i.e., without having to enter and re-enter their passwords. My first attempt was to use perl modules Net::LDAP and Authen::SASL. I could not get this working so fell back to using ldap command line tools, but even these I cannot seem to get working! When using mozldap tools, as specified in the admin manual, I get the following:
$ /usr/lib64/mozldap/ldapmodify -h ldaphost.mycompany.com -D uid=eharmic,ou=mydept,dc=mycompany -o mech=GSSAPI -o authid=eharmic < ../ldapmod.txt
Bind Error: Invalid credentials
Bind Error: additional info: SASL(-14): authorization failure:
Using openldap tools I strike exactly the same problem:
$ ldapmodify -Y GSSAPI -H LDAP://ldaphost.mycompany.com -D uid=eharmic,ou=mydept,dc=mycompany -U eharmic < ../ldapmod.txt
SASL/GSSAPI authentication started
ldap_sasl_interactive_bind_s: Invalid credentials (49)
additional info: SASL(-14): authorization failure:
I believe I have set up the mapping correctly:
dn: cn=MyMapping,cn=mapping,cn=sasl,cn=config
objectClass: top
objectClass: nsSaslMapping
cn: MyMapping
nsSaslMapRegexString: ^(.+)@MYCOMPANY.COM
nsSaslMapBaseDNTemplate: ou=mydept,dc=mycompany
nsSaslMapFilterTemplate: (uid=1)
It must be getting reasonably far because after doing the above I can see the LDAP service ticket in my "klist" output.

I've installed pure-ftp, and the firewall is open on port 21, the router has port forwarding.
I can connect to this machine, from my smart-phone and a laptop using its IP Address 77.xx.xx.xxx
I'm getting user OK but its not accepting my password or one I just made on another account
This is whats happening:-
What layer of extra security is stopping this working, as the guy attempting access is trying to send a file to big to attach to an e-mail.

I am running an FTP server using Pure-FTPD which was a migration from an OS-X workstation to Fedora 10 - VMware esxi.
This was done for various reasons but the reason for choosing the Pure-FTPD app was due to an easier migration.
The system has been migrated for about a month and works very well. I installed it on the server using yum install pure-ftpd, configured it and imported all the accounts [about 150 accounts] so this is all fab. however we now want to see if we can get an upload notification.
This has lead me to look at the uploadscript option in pure-ftpd. we use virtual users and the pure-pw file.
The Problem:
When we set the directive
Code:
The ftp server hangs, I cant seem to see how to get this to work, from my investigation I think the issue is that the yum install is not building the app " --with-uploadscript " i have tried to do a hand install on a test Fedora 10 VM, I downloaded pure-ftpd-1.0.27.tar.gz and unpacked it, did a ./configure --with uploadscript then a make and make install, nothing reports any errors but it doesnt seem to install anything. I can start the server from a command line but there are no config directories ? and even after creating a new user and a passwd-mkdb i cant log in to the server. but that most likely as i dont have a full configuration. but i can t find where to put the configuration files.

I'm trying to install Pure-FTPd. I'm going to use it via the internal file-based userlist.The problem is, when I yum install pure-ftpd from rpmforge or CentOS.Karan.Org, I also get mysql, perl-DBI and postgresql-libs as dependencies.Since I'm not intrested in DB-based authentication, I'd strongly prefer to skip these packages.Why are these listed as dependencies, since AFAIK, they are not really dependencies? Can I force yum to skip them somehow?

I have a "friend" who hosts a couple of websites that I maintain. I have always used filezilla client to connect and update the files on the website.I lost access for a little while and he said that "The profiles had accidentally been dropped".He reinstated everything but now I cannot complete a log on session. I maintain several other websites which have the same PURE FTPd server at their end and I can connect to these OK.The delicacy of the matter is that, with no changes at my end, and my other sites working, logic suggests that something has changed at his end. I have very patiently worked through all his suggestions but to no avail.I can't suggest that he is at fault when he claims expertise in the field and I am a complete lamer when it comes to FTP.
I wonder if anyone would be kind enough to review the log on result below and see if they can throw some light on the situation for me.(I have anonymised the IP address and other information for security reasons)

I'm having problems getting openssh server to accept connections in Ubuntu 10.04.Here's what I've done (twice): Installed Ubuntu 10.04 on USB drive with pendrive installer. This creates a default user "ubuntu" and you don't get the chance to choose a password for it. Started a keyring for network access and selected password. Works.Enabled VNC and selected password. Works fine with VNC client on local network. Logs in as "ubuntu" user and asks for the VNC password, then connects. Note: the client doesn't know the "ubuntu" user password, and neither do I! However, it works.Installed openssh client and server from Ubuntu s/w center.
$ ssh localhost OR $ ssh ubuntu@localhost try to connect, but asks for password, which I don't know (see step one, above) so, then I created a new user, with known password, logged in as new user in Ubuntu, works.however, $ ssh newuser@localhost still fails, even when correct password for <newuser> is supplied. Rejects the password three times, then gets the usual error about keys.I also tried connecting with an SSH terminal app from my iPad, again using <newuser>. It gets essentially the same error, "failure to authenticate".
All this is still on my own LAN, haven't gotten to going outside the router yet.What I want to do in the end is use VNC over SSH from a client on my iPad to talk securely to Ubuntu while I'm traveling.

I would like to recompile the openssh-server with a different version string. I download and compile the source, but so far I have only been able to compile and run the client. Not the server.
Steps taken:

I have recently discovered the following: when I attempt to connect to any of our machines that are OpenSSH 5.x (Ubuntu 10 or OpenSuSE 11.x in our case) as one of the users defined in the NIS domain that fails. For instance, me (user bepstein) can SSH into all those machines but not SFTP.I can SFTP into those machines on the network that are OpenSSH 4.x, however (CentOS 5.3 - 5.4, OpenSUSE 10.3).As a user defined locally on the machine (in /etc/passwd ) I can connect via either SSH or SFTP even if the machine is OpenSSH 5.x.Some further discussion of that issue is available here: http:[url]....

My Fedora Core 8 server came with OpenSSH Server 4.7p1 installed. I could not find a YUM package or RPM for 5.2p1, so I installed it manually and rebooted. Now if I do a version check with "sshd -v", it reports it's version as "OpenSSH_5.2p1", but if I connect with Putty, it reports "SSH-2.0-OpenSSH_4.7". Do I have two versions of OpenSSH running or what's going on?
