Public bug reported: Mounting a network share using mount.cifs through port 139 gives an input/output error. I'm using port 139 because the NAS I'm connecting to somehow needs a netbiosname. I'm using the following command:
/sbin/mount.cifs //IP/SHARE MOUNTPOINT -o rw,guest,dir_mode=0770,file_mode=0770,uid=1000,gid=1000,port=139,netbiosname=laptop This command used to work: I have not changed the software or settings of the NAS, only updated software on the client (laptop). Although I'm running Lubuntu I suspect this bug is related to Ubuntu. I have found an identical bug on Fedora/Red Hat, with a patch that is reported to work: https://bugzilla.redhat.com/show_bug.cgi?id=1068862 dmesg gives the following error, that is similar to the output given on the above link [ 4874.026333] WARNING: CPU: 1 PID: 12553 at /build/buildd/linux-3.13.0/fs/cifs/transport.c:313 smb_send_rqst+0x201/0x260 [cifs]() [ 4874.026336] Send length mismatch(send_length=72 smb_buf_length=2164260932) [ 4874.026338] Modules linked in: nls_utf8 cifs fscache ctr ccm rfcomm bnep bluetooth binfmt_misc uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_core videodev arc4 snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep snd_pcm snd_page_alloc pcmcia snd_seq_midi ath9k ath9k_common snd_seq_midi_event ath9k_hw joydev snd_rawmidi serio_raw ath mac80211 r592 yenta_socket lpc_ich memstick snd_seq snd_seq_device snd_timer snd pcmcia_rsrc pcmcia_core soundcore cfg80211 i915 asus_laptop video drm_kms_helper sparse_keymap drm mac_hid input_polldev parport_pc i2c_algo_bit ppdev coretemp lp parport ahci psmouse 8139too 8139cp sdhci_pci mii libahci sdhci [ 4874.026411] CPU: 1 PID: 12553 Comm: mount.cifs Tainted: G W 3.13.0-36-generic #63-Ubuntu [ 4874.026414] Hardware name: ASUSTeK Computer Inc.
